Exhibit.

After an initial setup of CX 8325 VSX configuration, the active gateway is set up for SVI 10. For testing purposes. SVI 10 on sw-aggi is shut down while traffic from the client connected to Edge-1 is initiated towards the default route.
What is the expected behavior white performing this test?

• A. Traffic is potentially dropped between the client and the destination.
• B. Traffic Is unaffected and a 50nsfailover time is expected for agg-sw2 to start traffic forwarding.
• C. Traffic is dropped and vsx-sync will disable SVI10 on agg-sw2 automatically.
• D. Traffic is forwarded over the ISL without the risk of dropped packets.

Answer: B

Explanation:
The question involves a VSX configuration with CX 8325 switches (agg-sw1 and agg-sw2) where SVI 10's active-gateway is set up. For testing, SVI 10 on agg-sw1 is shutdown, and traffic from a client connected to Edge-1 is initiated toward the default route. The task is to determine the expected behavior.
* Analysis of Options:
* Option A:Incorrect. Traffic is not dropped, as VSX ensures redundancy via the active-gateway on agg-sw2.
* Option B:Incorrect. Traffic does not traverse the ISL unnecessarily; agg-sw2 takes over directly.
* Option C:Correct. Traffic continues unaffected, with a 50ms failover time for agg-sw2 to assume forwarding responsibilities for SVI 10.
* Option D:Incorrect. Traffic is not dropped, and vsx-sync does not disable SVI 10 on agg-sw2; it ensures consistency.
* Why Option C is Correct:In a VSX cluster with active-gateway, both switches (agg-sw1 and agg- sw2) share a virtual IP and vMAC for SVI 10, allowing either to respond to ARP requests and forward traffic. Shutting down SVI 10 on agg-sw1 triggers agg-sw2 to take over Layer 3 forwarding, leveraging the active-gateway configuration. VSX's fast failover mechanism ensures a typical failover time of approximately 50ms, making the transition seamless for clients on Edge-1. The vsx-sync feature ensures SVI configurations remain consistent, preventing traffic disruption. This behavior aligns with HPE Aruba Networking's VSX high-availability design.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting VSX for high availability.
* Routing (16%):Ensuring seamless Layer 3 forwarding in VSX environments.
* Troubleshooting (10%):Diagnosing failover behavior in campus networks.

NEW QUESTION # 29
Refer to the exhibit.

A gateway cluster needs to be connected to the VSX-enabled switches where MC-LAG is configured What Is a possible constraint?

• A. LACP is not supported during the initial provisioning and needs to be turned off.
• B. LLDP needs to be enabled to detect LACP-configured interfaces.
• C. lacp mode active needs to be configured on the gateways when usingstatic-activate" mode.
• D. The command lacp fallback is missing on the interface lag level.

Answer: A

Explanation:
The question asks about a possible constraint when connecting an Aruba Gateway Cluster to upstream VSX switches using an MC-LAG.
* Scenario:Gateway Cluster acts as a single logical device forming an LACP LAG. The VSX switches are configured with MC-LAG, allowing the gateway cluster to bundle links across the two physical VSX switches.
* LACP & Initial Provisioning:LACP requires negotiation (exchange of LACP PDUs) between both ends of the link bundle to activate the LAG. During initial gateway provisioning (ZTP, OTP), the gateway might be in a minimal state without its full configuration, including LACP parameters. If the VSX switch ports are configured strictly for LACP active mode, the LAG might not form until the gateway is fully provisioned and running LACP. This lack of connectivity during provisioning is a constraint.
* Analysis of Options:
* A: lacp mode active is standard, but the issue is during provisioning, not runtime mode choice.
"static-activate" is unrelated.
* B: Theabsenceof lacp fallback could be the constraint. Fallback allows connectivity if LACP doesn't establish, which is useful during provisioning.
* C: LLDP is not required for LACP.
* D: Correctly identifies the constraint: Standard LACP required by the switch might not be supported or active on the gateway during its initial provisioning phase, potentially hindering the setup process. Workarounds like disabling LACP or enabling LACP fallback on the switch ports during this phase are often necessary.
* Conclusion:LACP incompatibility during the initial provisioning phase of the gateway cluster is a common constraint when connecting to switches requiring LACP for the LAG.

NEW QUESTION # 30
Exhibit.

A conference venue has a requirement to secure independent network users from each other in their network.
The following configurations are created on Edge-1:

• A. change the VLAN 152 type. primary-vlan 152
• B. change the VLAN 152 private-vlan community
• C. change the VLAN 151 primary-vlan 151
• D. change the VLAN 151 private-vlan community

Answer: D

Explanation:
The requirement is to secure independent network users from each other in a conference venue using Edge-1.
This scenario typically calls for Private VLANs,specifically using the 'isolated' type to prevent communication between hosts within the same secondary VLAN.
* Analysis of Options:
* Private VLANs consist of a primary VLAN and one or more secondary VLANs (isolated or community). Isolated ports cannot communicate with other isolated ports in the same VLAN; they can only communicate with promiscuous ports (usually the router uplink). Community ports can communicate with each other and promiscuous ports.
* Option A: Configures VLAN 152 as private-vlan community.
* Option B: Configures VLAN 151 as private-vlan community.
* Option C: Defines VLAN 152 as a primary-vlan associated with itself, which isn't standard syntax
/logic.
* Option D: Defines VLAN 151 as a primary-vlan associated with itself.
* The goal isisolation. None of the options directly configure an isolated VLAN. Options A and B configure community VLANs, which allow communication between users within that VLAN, contradicting the requirement. Options C and D attempt to define primary VLANs in a potentially incorrect way.
* Caveat:There seems to be an issue with the provided options. Standard configuration to make VLAN 151 isolated would involve defining a primary VLAN (e.g., vlan 152 private-vlan primary) and then defining VLAN 151 as isolated (vlan 151 private-vlan isolated). Since none of the options correctly configure anisolatedVLAN, and the requirement is isolation, the question or options are likely flawed. However, if forced to interpret intent, questions sometimes test understanding of thetypesof private VLANs. Changing a VLANtocommunity type (Option B for VLAN 151) is a distinct action, even if it doesn't meet the statedisolationgoal. Without correct options for 'isolated', selecting the 'best' flawed option is difficult. Assuming the question intends to configure VLAN 151 assome typeof private secondary VLAN, Option B modifies VLAN 151's private VLAN characteristic.
* Conclusion:Based on the requirement for isolation, none of the provided options are correct. However, if assuming a potential error in the question or options and needing to select the closest modification related to private VLAN types for VLAN 151, Option B is chosen tentatively, despite configuring
'community' instead of the required 'isolated'.

NEW QUESTION # 31
When using the cable diagnostic feature on an AOS-CX switch to test a 1000BaseT connection, whatthe accuracy of 'distance to fault"?

• A. +/- 10m
• B. +/-1m
• C. +/-6m
• D. +/- 2m

Answer: B

Explanation:
The question asks about the accuracy of the 'distance to fault' measurement provided by the cable diagnostic feature (using Time Domain Reflectometry - TDR) on an AOS-CX switch for a 1000BaseT connection.
* TDR Accuracy:TDR works by sending a signal down the cable and measuring the time it takes for reflections to return, which indicates faults like opens or shorts. The accuracy depends on the quality of the TDR circuitry, the calibration,and the cable characteristics. Network equipment vendors typically specify the expected accuracy.
* AOS-CX Specification:According to HPE Aruba Networking documentation for AOS-CX switches, the accuracy of the TDR-based cable diagnostics for distance to fault on copper cabling is typically specified as +/- 1 meter.
* Analysis of Options:
* A: +/- 10m - Too inaccurate.
* B: +/- 2m - Less accurate than specified.
* C: +/- 6m - Too inaccurate.
* D: +/- 1m - Matches the documented accuracy for AOS-CX TDR.

NEW QUESTION # 32
An IT administrator uses AOS-CX switches to send TCP 22 trafficfrom the switch port to a remoteserver for analysis. The administrator now wants to save it locally tobedownloaded and used later in case the admin changes their mind about the approach to take.

• A. destination cpu
• B. destination tunnel file tshark-pcpap
• C. destination file tshatk-pcap
• D. destination flash:/.'my-mirror.pcnap policy Policy Minor22

Answer: C

Explanation:
The question involves an AOS-CX switch administrator using a packet capture (e.g., tshark) to monitor TCP port 22 traffic and wanting to save it locally for later download, instead of sending it to a remote server.
* Analysis of Options:
* Option A:Correct. The destination file tshark-pcap command specifies that the packet capture output is saved to a local file (e.g., tshark-pcap) on the switch's flash storage.
* Option B:Incorrect. destination tunnel file tshark-pcpap is not a valid AOS-CX command for local storage.
* Option C:Incorrect. destination cpu is not relevant for saving packet captures; it may refer to CPU-based monitoring.
* Option D:Incorrect. destination flash:/.'my-mirror.pcnap policy Policy Minor22 has invalid syntax and does not align with packet capture storage.
* Why Option A is Correct:In AOS-CX, packet captures can be configured using the monitor command (e.g., monitor session 1 source interface 1/1/1 destination file tshark-pcap). The destination file tshark- pcap option saves the captured packets (e.g., TCP port 22 traffic) to a local file on the switch's flash storage, which can be downloaded later via SCP, SFTP, or the Web UI. This meets the administrator's requirement to store the capture locally for future analysis, aligning with AOS-CX's packet capture capabilities.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Performing advanced troubleshooting using packet captures.
* Performance Optimization (6%):Analyzing network traffic for performance issues.
* Connectivity (9%):Diagnosing connectivity issues with monitoring tools.

NEW QUESTION # 33
Match the BGP connection states to the conditions that could have caused that state.

Answer:

Explanation:

Explanation:
The last keepalive is less than 3 times the negotiated holddown timer. -->established The router has not received a response. The neighbor might be unreachable. -->active The router is waiting for an initial response from the neighbor. -->connect The router starts listening for a connection. -->idle This question requires matching specific BGP connection states from the BGP Finite State Machine (FSM) to descriptions of the router's activity or condition in those states.
* Idle:This is the starting state. The BGP process is administratively up but is not actively trying to connect. It refuses all incoming BGP connection attempts but listens for a start event (like configuration or operator initiation) or potentially listens for incoming connections if configured for passive peering.
* Matches:"The router starts listening for a connection." (This describes the passive aspect of the Idle state before active attempts begin).
* Connect:In this state, BGP is actively trying to establish a TCP connection with the peer. It has initiated the TCP three-way handshake and is waiting for it to complete, or it is waiting for a remote peer to initiate the TCP connection.
* Matches:"The router is waiting for an initial response from the neighbor." (Specifically, waiting for the TCP handshake to complete).
* Active:If the TCP connection attempt in the Connect state fails (e.g., timeout), the router transitions to the Active state. In this state, it will periodically retry establishing the TCP connection while also listening for an incoming connection from the peer. This state indicates repeated failures to establish TCP connectivity.
* Matches:"The router has not received a response. The neighbor might be unreachable." (This reflects the condition in the Active state where connection attempts fail, suggesting the neighbor is unreachable at the TCP level).
* Established:This is the final, operational state where the TCP connection is up, BGP session parameters have been successfully negotiated via OPEN messages, and KEEPALIVE messages are being exchanged. Routing information (UPDATEs) can be exchanged. The condition described implies the session is healthy and timers are being maintained.
* Matches:"The last keepalive is less than 3 times the negotiated holddown timer." (While phrased slightly unusually, this indicates the holddown timer hasnotexpired because keepalives are being received within the expected window (Holddown Timer = ~3 * Keepalive Interval). This confirms the session is alive, which is true in the Established state).

NEW QUESTION # 34
A customer is trialing the below colorless port configuration on a single switch and has noticed that users roaming to access points connected to the test switch are unable to receive an IP address on the corporate Wi- R network, which is operating in bridged mode All other SSIDs are working as expected and the AP is Online in HPE Aruba Networking Central.
The security team reports that there have been no failed authentications m HPE Aruba Networking ClearPass Access Tracker and that the last entry for the wiredport is returning the KADIUS Aruba-User-Hold attribute
'Access_Point.
Which configuration change is required to resolve the issue?

• A. interface 1/1/1-1/1/48
  aaa authentication port-access client-limited 0
• B. port-access client-move enable
• C. interface 1/1/1/1-1/48
  port-access onboarding-method concurrent enable
• D. port access role Access_point auth-mode device-mode

Answer: A

Explanation:
The issue involves users roaming to APs connected to a test switch failing to receive an IP address on the corporate Wi-Fi network (bridged mode), with ClearPass reporting a RADIUS Aruba-User-Role attribute of Access_Point. The goal is to identify the configuration change needed to resolve this issue.
* Analysis of Options:
* Option A (port-access client-move enable):Enables client movement between ports but does not address the AP authentication issue.
* Option B (aaa authentication port-access client-limit 0):Correct. Setting the client limit to 0 on the switch ports (1/1/1-1/1/48) disables MAC authentication for APs, allowing them to be treated as trusted devices and preventing the application of an incorrect role.
* Option C (port-access onboarding-method concurrent enable):Enables concurrent onboarding but is unrelated to the AP role issue.
* Option D (port-access role Access_point auth-mode device-mode):Configures a device mode role but does not resolve the IP assignment issue caused by incorrect authentication.
* Why Option B is Correct:The issue arises because the switch is applying 802.1X or MAC authentication to the AP ports, resulting in ClearPass assigning the Access_Point role, which restricts client connectivity. By setting aaa authentication port-access client-limit 0 on the AP-connected ports (1
/1/1-1/1/48), the switch disables port-access authentication for these ports, treating the APs as trusted devices. This allows clients to authenticate properly via the AP and receive IP addresses in bridged mode, resolving the issue.
* Relevance to Certification Objectives:
* WLAN (9%):Involves troubleshooting wireless functions and Layer 2 issues related to AP connectivity.
* Authentication/Authorization (9%):Includes troubleshooting ClearPass integration and 802.1X configurations.
* Security (10%):Covers troubleshooting wired 802.1X implementations.

NEW QUESTION # 35
A client is unable to connect to the network, In the HPE Aruba Networking ClearPass access tracker, wo can seean EAP timeout What is a possible cause of this message?

• A. The client does not trust the radius server certificate.
• B. The radius server can seethat theclient certificate is expired.
• C. The client can see that theradiusserver certificateis expired.
• D. The radius server doesnot trust the client certificate

Answer: A

Explanation:
The question involves an EAP timeout in HPE Aruba Networking ClearPass Access Tracker during an 802.1 X authentication attempt, with the task of identifying a possible cause.
* Analysis of Options:
* Option A:Incorrect. A client certificate trust issue would cause a different error, not an EAP timeout.
* Option B:Incorrect. An expired client certificate would result in an authentication failure, not a timeout.
* Option C:Incorrect. If the client sees an expired RADIUS server certificate, it would reject it, but this typically causes a trust error, not a timeout.
* Option D:Correct. If the client does not trust the RADIUS server's certificate (e.g., missing CA certificate or untrusted issuer), it may fail to proceed with the EAP handshake, leading to an EAP timeout.
* Why Option D is Correct:In 802.1X authentication with EAP (e.g., EAP-TLS or EAP-PEAP), the client must trust the RADIUS server's certificate to establish a secure TLS tunnel. If the client's trust store lacks the Certificate Authority (CA) certificate or the server's certificate is untrusted (e.g., self- signed without proper installation), the clientaborts the EAP handshake, resulting in an EAP timeout logged in ClearPass. This is a common issue in 802.1X deployments and can be resolved by ensuring the client has the correct CA certificate or by using a trusted server certificate, as per HPE Aruba Networking's security guidelines.
* Relevance to Certification Objectives:
* Authentication/Authorization (9%):Troubleshooting 802.1X and ClearPass authentication issues.
* Security (10%):Diagnosing wired 802.1X with EAP-TLS failures.
* Troubleshooting (10%):Resolving authentication timeouts in campus networks.

NEW QUESTION # 36
The customer is experiencing periodic uplink congestion between campus-1's AGG-1 and core. This has boon negativelyaffecting voice communications.The VOIP phones edge mark their packets with DSCP EF. The uplink from AGG-1 to core is LAG1.
The customer has already configured the following class and policy on AGG-1:

Based on this policy, which scrip), when deployed on AGG-1. will improve the reliable forwarding of voice trafficbetween AGG-1 and its uplink to the core?

• A.
• B.
• C.
• D.

Answer: D

Explanation:
The problem describes uplink congestion affecting VoIP traffic (marked with DSCP EF, value 46) on AGG-
1's LAG1 uplink. The existing configuration classifies this traffic into voip_class and applies voip_policy inbound, setting local-priority 6. To improve reliable forwarding during congestion, VoIP traffic needs strict priority queuing on the egress interface (LAG1).
* Analysis of Options:
* Option A applies a QoS schedule profile globally but doesn't modify the policy's local-priority or apply the schedule profile specifically to the congested LAG.
* Option B modifies voip_policy to set local-priority 7 (mapping DSCP 46 traffic to queue 7) and applies the 8qDwrStrict schedule profile to the egress interface lag 1. In the 8qDwrStrict profile, queue 7 is configured for strict priority, ensuring voice traffic gets precedence over lower-priority traffic during congestion. This aligns with best practices for QoS for VoIP.
* Option C also sets local-priority 7 and applies the schedule profile to lag 1, but the profile itself configures queue 7 with DWRR (Deficit Weighted Round Robin) instead of strict priority, which is less suitable for delay-sensitive voice traffic.
* Option D applies a schedule profile globally and uses DWRR for queue 7.
* Conclusion:Option B is the correct solution because it maps the DSCP EF traffic to the highest local priority (7) and applies a QoS schedule profile to the specific congested uplink (lag 1) that treats queue
7 with strict priority. This ensures voice traffic is prioritized reliably.

NEW QUESTION # 37
Refer to the exhibit which illustrates the current configuration of Router-1.

Clients of VLAN 10 require access to services hosted in the 10.1.100.0/24subnet. This 'equites one 01 more routes to be added to Rculer-1 that do not currently exist.
Which script would install a route from 10.2.10.0/24 to 10.1.100.0/24 on Router-1? A return path is not required as part of this answer.

• A. ip route 0.0.0.0/0 10.255.101.11 vrf service
  ip route 10.255.101.0/24 1/1/1 vrf IoT-Medical
  ip route 10.1.100.0/24 10.255.101.11 vrf IoT-Medical
• B. ip route 0.0.0.0/0 10.255.101.11 vrf service
  ip route 10.1.100.0/24 1/1/1:10.255.101.11 vrf IoT-Medical
• C. there is no solution as Core-1 is not part of VRF service
• D. ip route 0.0.0.0/0 10.255.101.11 vrf service
  ip route 10.1.100.0/24 1/1/1 vrf IoT-Medical

Answer: A

Explanation:
The goal is to add a static route on Router-1 to allow clients in VLAN 10 (subnet 10.2.10.0/24, presumably in VRF 'IoT-Medical' based on options) to reach services in the 10.1.100.0/24 subnet. The exhibit indicates interface 1/1/1 (IP 10.255.101.10/24) is in VRF 'service', and the likely next hop towards the destination is Core-1 at 10.255.101.11 (also implied to be reachable via VRF 'service'). This requires adding a route in the source VRF ('IoT-Medical') pointing towards the destination via the next hop in the 'service' VRF.
* Static Route Syntax (with VRF):ip route <destination_prefix> <next-hop-ip> [vrf <source-vrf>]
* Analysis of Options:
* A: Claims Core-1 isn't in VRF 'service', contradicting the likely setup.
* B: Uses unusual interface:ip syntax (1/1/1:10.255.101.11). Defines the route in VRF 'IoT- Medical'.
* C: Uses interface 1/1/1 as the next hop. This is less specific than using the IP address and relies on the interface being point-to-point or having proxy ARP enabled. Defines the route in VRF
'IoT-Medical'.
* D: ip route 10.1.100.0/24 10.255.101.11 vrf IoT-Medical. This uses the standard syntax to define a static route for the destination 10.1.100.0/24 via the next-hop IP 10.255.101.11 within the context of the IoT-Medical VRF. The successful function of this route depends on inter-VRF routing (route leaking) being configured between 'IoT-Medical' and 'service' VRFs, but the command itself correctly defines the desired static route.
* Conclusion:Option D provides the correct and standard command syntax to configure the required static route within the specified source VRF ('IoT-Medical').

NEW QUESTION # 38
Two CX 8325 switches are configured as a cluster using VSX for the coreroleand two CX 6300M in VSF for theaggregation role. When a minor software upgrade is issued on the switches, what isthe method to achieve a hitlessupgrade with the aggregation switches?

• A. ISSU update-software initiates the upgrade first on the primary switch, followed by the secondary.
• B. ISSU update-software initiates the upgrade first on thesecondary switch, Followed by theprimary.
• C. VSF update-software initiates thesoftware upgrade first on the primary switch. followed by the secondary.
• D. VSF update-software initiates the software Upgrade first on the secondary switch, followed by the primary.

Answer: D

Explanation:
The question involves a minor software upgrade on a VSF (Virtual Switching Framework) stack of CX
6300M switches in the aggregation role, with CX 8325 switches in a VSX cluster as the core. The task is to identify the method for a hitless upgrade on the aggregation switches.
* Analysis of Options:
* Option A:Correct. VSF upgrades start with the secondary switch, followed by the primary, to ensure continuous operation without traffic disruption.
* Option B:Incorrect. In-Service Software Upgrade (ISSU) is used for VSX, not VSF, and follows a different process.
* Option C:Incorrect. Upgrading the primary switch first in VSF risks disrupting control plane operations.
* Option D:Incorrect. ISSU is not applicable to VSF upgrades.
* Why Option A is Correct:In a VSF stack, the update-software command initiates a rolling upgrade, starting with the secondary (standby) switch to ensure the primary (commander) continues handling traffic. Once the secondary is upgraded and rejoins the stack, the primary is upgraded, maintaining hitless operation. This process leverages VSF's ability to keep member switches active during upgrades, minimizing downtime. The CX 6300M's VSF implementation supports this hitless upgrade mechanism, as per HPE Aruba Networking documentation.

NEW QUESTION # 39
Match the BGP connection slates to the conditions thatcould have caused that state.

Answer:

Explanation:

Explanation:
The router is able to process update messages. -->established
The router is waiting for the neighbor's open message. -->open sent
Routers have agreed on matching feature sets. -->open confirm
The session establishment has timed out. -->idle
This question requires matching BGP connection states from the BGP Finite State Machine (FSM) to descriptions of conditions that occur within or lead to those states.
* Idle:This is the initial state where BGP awaits a start event or retries after a failure. It's also the state entered upon error detection or session closure, including timeouts during connection attempts.
* Matches:"The session establishment has timed out." - A timeout during the connection process forces the BGP process back to the Idle state to potentially retry later.
* OpenSent:After a TCP connection is established, the local router sends a BGP OPEN message with its parameters (AS number, capabilities, etc.) and transitions to the OpenSent state while waiting to receive an OPEN message from its BGP neighbor.
* Matches:"The router is waiting for the neighbor's open message."
* OpenConfirm:Once the router receives an OPEN message from its neighbor and validates the parameters (e.g., matching AS, compatible capabilities), it sends a KEEPALIVE message and moves to the OpenConfirm state. It waits for a KEEPALIVE from the neighbor to confirm the session. Basic parameter checks and capability negotiations are successfully completed in this phase.
* Matches:"Routers have agreed on matching feature sets." - This agreement happens upon successful validation of the OPEN messages exchanged.
* Established:This is the final, stable state where BGP peering is successful. Both routers have accepted each other's parameters via the OPEN messages and confirmed the session with KEEPALIVEs. In this state, the routers can exchange UPDATE messages containing routing information.
* Matches:"The router is able to process update messages."

NEW QUESTION # 40
Which issue may becausing the new door locks on the APs to notwork?

• A. BT power to the AP is too much.
• B. AT power to the AP is too much.
• C. AF power to the AP is not enough.
• D. AT power to the AP is notenough.

Answer: C

Explanation:
New PoE-powered door locks, connected via the PoE passthrough port on Aruba APs, are not working. We need to find the likely cause related to PoE power.
* PoE Passthrough:An AP feature where the AP, powered by PoE from a switch, provides PoE power out to another device connected to one of its Ethernet ports.
* Power Budget:The AP must receive enough power from the switch via its PoE input (e.g., 802.3af,
802.3at, 802.3bt) to power itselfandmeet the power demand of the downstream device (the door lock).
* PoE Standards Power (Approx. Available to Device):
* 802.3af (PoE): ~13 Watts
* 802.3at (PoE+): ~25.5 Watts
* 802.3bt (PoE++): 51W (Type 3) or 71W (Type 4)
* Analysis:Modern APs (especially Wi-Fi 6/6E) can consume significant power themselves (>15W or
>25W under load). Standard 802.3af PoE (supplying only ~13W) is often insufficient to power both a modern AP and a downstream PoE device like a door lock. The AP will power up, but won't enable PoE output if its input power budget is insufficient.
* Analysis of Options:
* A, B: Too much power (AT/BT) isn't the issue; devices only draw what they need.
* C: AF power (~13W) received by the AP is very likelynot enoughto power both the AP and the door lock.
* D: AT power (~25.5W)mightbe insufficient if the combined load of the AP and lock exceeds this, but AF being insufficient (C) is a more common limitation.
* Conclusion:Insufficient input power to the AP is the most common reason for PoE passthrough failure.
802.3af (PoE) power is often inadequate.

NEW QUESTION # 41
You haverecently configured a switch for 802.IX authentication with HPE Aruba Networking ClearPass. A security admin is seeing events withthe following description in ClearPass Event Viewer.
RADIUS authentication attempt from unknown NAD (10.10.1.10:1812)'
Which command should you us to identify theconfiguration issue?

• A. show ip source-interfaceradius
• B. show radius-server shared-secret
• C. show radius-server detail
• D. show aaa authentication-server radius

Answer: A

Explanation:
The ClearPass Event Viewer message "RADIUS authentication attempt from unknown NAD (10.10.1.10:
1812)" indicates that ClearPass received a RADIUS request from the IP address 10.10.1.10, but this IP is not configured as a trusted Network Access Device (NAD) in ClearPass's network device list, or the shared secret doesn't match. The first step in troubleshooting on the switch side is to verify which source IP address the switch is actually using to send these RADIUS requests.
* RADIUS Source IP:AOS-CX switches can be configured to use a specific source IP address for RADIUS packets, often using the ip source-interface radius [vrf <vrf-name>] command. This is important if the switch has multiple IP interfaces or uses VRFs.
* Analysis of Commands:
* A. show ip source-interface radius: This command directly displays the configured source interface and IP address used for RADIUS communications, allowing comparison with the IP configured in ClearPass.
* B. show aaa authentication-server radius: Shows server group configuration, not the source IP used by the switch.
* C. show radius-server shared-secret: Not a standard command; secrets are usually masked in other commands.
* D. show radius-server detail: Shows configured RADIUS server details but doesn't explicitly show the source IP the switch is using to originate packets.
* Conclusion:To identify why ClearPass sees requests from an "unknown NAD" IP (10.10.1.10), the first step on the switch is to confirm which source IP it's using. show ip source-interface radius provides this crucial information.

NEW QUESTION # 42
A senior engineer from the network operations team has reported an intermittent problem where some PoE- powered devices are randomly losing power. During your investigation, you found that port 1 of the Acc-1 switch is currently presenting the behavior shown in the CLI output for the Acc-1.

What is a probablecausa lot poor 1/1/1 is denying PoE?

• A. PoE port priority sot to low
• B. This switch does no! support PoE class 4.
• C. PoE was manually disabled for port 1/1/1.
• D. switch PoE powerbudget exceeded

Answer: D

Explanation:
The question involves intermittent PoE-powered device power loss on port 1/1/1 of an AOS-CX switch (Acc-
1), with CLI output (not provided) indicating a PoE issue. The task is to identify a probable cause.
* Analysis of Options:
* Option A:Incorrect. AOS-CX switches typically support PoE Class 4 (802.3at, 30W), sufficient for most devices.
* Option B:Correct. If the switch's PoE power budget is exceeded, it may deny power to port 1/1
/1, causing intermittent device failures.
* Option C:Incorrect. Low PoE port priority may deprioritize the port but is less likely to cause complete power loss compared to budget issues.
* Option D:Incorrect. Manual disabling of PoE would cause consistent power loss, not intermittent issues.
* Why Option B is Correct:AOS-CX switches have a finite PoE power budget (e.g., 370W or 740W, depending on the model and power supply). If the total power demand from connected devices exceeds this budget, the switch denies power to some ports, often intermittently as devices cycle or negotiate power. For port 1/1/1, this could manifest as random power loss for the connected device. The CLI output likely shows a "power denied" status (e.g., via show power-over-ethernet brief). Checking the PoE budget (show power-over-ethernet) and upgrading power supplies or prioritizing critical ports resolves the issue, aligning with HPE Aruba Networking's PoE troubleshooting guidelines.
* Relevance to Certification Objectives:
* Connectivity (9%):Troubleshooting PoE deployment issues.
* Troubleshooting (10%):Diagnosing power-related issues in campus networks.
* Switching (19%):Implementing PoE configurations for Layer 2 devices.

NEW QUESTION # 43
Exhibit.

After Implementing a distributed overlay with distributed anycast gateways, you noticed that toomany ARP packets are being replicated to every access (leaf) switch Which command can you use to optimize the network?

• A. vlan 10 arp-suppression vlan 11 arp-suppression
• B. evpn ip proxy-arp
• C. interface vlan 10 ip proxy-arp interface vlan 11 ip proxy-arp
• D. evpn arp-suppression

Answer: D

Explanation:
In an EVPN VXLAN distributed overlay network, excessive ARP packet replication (flooding) to all leaf switches is observed. We need the command to optimize this.
* EVPN ARP Optimization:EVPN uses its control plane (BGP) to distribute MAC and IP address reachability information. Leaf switches (VTEPs) learn these mappings. To reduce ARP flooding across the VXLAN fabric:
* ARP Suppression:VTEPs intercept ARP requests. If the VTEP already knows the MAC address for the requested IP (learned via EVPN), it can suppress the ARP request, preventing it from being flooded over VXLAN.
* Proxy ARP:VTEPs intercept ARP requests. If the VTEP knows the MAC for the requested IP, it can generate an ARP replyon behalfof the remote host.
* AOS-CX Commands:These features are configured within the EVPN context.
* evpn arp-suppression (B): Enables the ARP suppression feature for EVPN.
* evpn ip proxy-arp (C): Enables the proxy ARP feature for EVPN.
* Options A and D use standard interface/VLAN level arp-suppression or proxy-arp commands, which are not specific to optimizing flooding within the EVPN VXLAN fabric itself.
* Conclusion:To optimize by reducing the replication/flooding of ARP packets across the EVPN VXLAN overlay, enabling evpn arp-suppression (Option B) is the direct command. This leverages the EVPN control plane knowledge to stop unnecessary ARP flooding.
