NEW QUESTION # 31
Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.
What is correct about access from the servers to the Core? (Select two.)
- A. Server 2 cannot access the core layer.
- B. Server 1 and Server 2 can communicate with each other via the core layer
- C. Server 1 can access the core layer on only one uplink
- D. Server 1 can access the core layer via both uplinks
- E. Server 1 can access the core layer via the keepalrve link
- F. Server 2 can access the core layer via the keepalive link
Answer: B,D
Explanation:
These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question.

NEW QUESTION # 32
How is Dynamic Multicast Optimization (DMO) implemented in an HPE Aruba wireless network?
DMO is configured individually tor each SSID in use in the network.
The AP uses OOS to provide equal air time for multicast traffic,
DMO is configured globally for each SSID in use in the network.
The controller converts multicast streams into unicast streams.
- A. DMO is not configured globally for each SSID in use in the network. DMO is configured individually for each SSID, as different SSIDs may have different multicast requirements.
- B. The controller does not convert multicast streams into unicast streams. The AP does the conversion, as it is closer to the wireless clients and can optimize the transmission based on the client capabilities and channel conditions.
- C. The AP does not use QoS to provide equal air time for multicast traffic. QoS is a feature that prioritizes different types of traffic based on their importance and latency sensitivity. QoS does not affect how multicast streams are transmitted over the wireless link.
- D. DMO is configured individually for each SSID in use in the network.
DMO is a feature that allows the AP to convert multicast streams into unicast streams over the wireless link. This enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. DMO is configured individually for each SSID in use in the network, as different SSIDs may have different multicast requirements.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure DMO is:
Dynamic multicast optimization: Select Enabled to allow IAP to convert multicast streams into unicast streams over the wireless link.

What is enabled by LLDP-MED? (Select two.)
- A. iSCSl client devices can request to have flow control enabled
- B. iSCSl client devices can set the required MTU setting for the port.
- C. GVRP VLAN information can be used to dynamically add VLANs to a trunk
- D. APs can request power as needed from PoE-enabled switch ports
- E. Voice VLANs can be automatically configured for VoIP phones
Answer: D,E
Explanation:
These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery). LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies. Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to adjust their power consumption and performance based on the available power budget. The other options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED.

NEW QUESTION # 34
Your customer is interested in hearing more about how roles can help keep consistent policy enforcement in a distributed overlay fabric How would you explain this concept to them''
- A. Group Based Policy ID is applied on egress VTEP after device authentication and policy is enforced on ingress VTEP
- B. Role-based policies are tied to IP addresses which have an advantage over IP-based policies and role names are sent between VTEPs
- C. Role-based policies enhance User Based Tunneling across the campus network and the policy traffic is protected with iPsec
- D. Group Based Policy ID is applied on ingress VTEP after device authentication and policy is enforced on egress VTEP
Answer: D
Explanation:
This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms.

NEW QUESTION # 36
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)
- A. A client associates and authenticates with the AP2 after roaming from AP1
- B. The Key Management service receives from AirMatch a list of all AP2's neighbors
- C. The Key Management service then generates R1 keys for AP2's neighbors.
- D. AP1 will cache the client's information and send it to the Key Management service
- E. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
Answer: C,D
Explanation:
Explanation
The correct steps that are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2 are A and D.
A: AP1 will cache the client's information and send it to the Key Management service. This is true because when a client associates and authenticates with AP1, AP1 will generate a pairwise master key (PMK) for the client and store it in its cache. AP1 will also send the PMK and other client information, such as MAC address, VLAN, and SSID, to the Key Management service, which is a centralized service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) devices1. The Key Management service will use this information to facilitate fast roaming for the client.
D: The Key Management service then generates R1 keys for AP2's neighbors. This is true because when the Key Management service receives the client information from AP1, it will use the PMK to derive R0 and R1 keys for the client. R0 keys are used to generate R1 keys, which are used to generate pairwise transient keys (PTKs) for encryption. The Key Management service will distribute the R1 keys to AP2 and its neighboring APs, which are determined by AirMatch based on RF proximity2. This way, when the client roams to AP2 or any of its neighbors, it can skip the 802.1X authentication and use the R1 key to quickly generate a PTK with the new AP3.
B: The Key Management service receives from AirMatch a list of all AP2's neighbors. This is false because the Key Management service does not receive this information from AirMatch directly. AirMatch is a feature that runs on MCs or MM devices and optimizes the RF performance of Aruba devices by using machine learning algorithms. AirMatch periodically sends neighbor reports to all APs, which contain information about their nearby APs based on signal strength and interference. The APs then send these reports to the Key Management service, which uses them to determine which APs should receive R1 keys for a given client2.
C: The Key Management service receives a list of all AP1 s neighbors from AirMatch. This is false for the same reason as B. The Key Management service does not receive this information from AirMatch directly, but from the APs that send their neighbor reports.
E: A client associates and authenticates with the AP2 after roaming from AP1. This is false because a client does not need to authenticate with AP2 after roaming from AP1 if it has already authenticated with AP1 and received R1 keys from the Key Management service. The client only needs to associate with AP2 and perform a four-way handshake using the R1 key to generate a PTK for encryption3. This is called fast roaming or
802.11r roaming, and it reduces the latency and disruption caused by full authentication.1: ArubaOS 8.7 User Guide 2: ArubaOS 8.7 User Guide 3: ArubaOS 8.7 User Guide : ArubaOS 8.7 User Guide
NEW QUESTION # 37
Which method is used to onboard a new UXI in an existing environment with 802 1X authentication? (The sensor has no cellular connection)
- A. Connect the new UXI from an already installed one and adjust the initial configuration.
- B. Use the Aruba installer app on your smartphone to scan the barcode
- C. Use the UXI app on your smartphone and connect the UXI via Bluetooth
- D. Use the CLI via the serial cable and adjust the initial configuration.
Answer: C
Explanation:
To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

NEW QUESTION # 38
you need to have different routing-table requirements With Aruba CX 6300 VSF configuration.
Assuming the correct layer-2 VLAN already exists, how would you create a new SVI for a separate routing table?
- A. create a new VLAN, and attach the VRF to it.
- B. Create a new SVI and use attach command.
- C. Create a new VLAN. and attach the routing table to it
- D. Create a new routing table, and attach VLANS to it
Answer: B
Explanation:
Explanation
The correct answer is C. Create a new SVI and use attach command.
To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.
According to the AOS-CX Virtual Switching Framework (VSF) Guide1, one of the steps to configure VRF-aware VSF is:
Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:
switch(config)# vrf red
switch(config-vrf)# exit
switch(config)# interface vlan 10
switch(config-if-vlan)# ip address 10.1.1.1/24
switch(config-if-vlan)# attach vrf red
The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of
10.1.1.1/24.
The other options are incorrect because:
A: You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.
B: You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.
D: You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.
NEW QUESTION # 39
With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?
- A. VRIDs need to be non-overlapping with VRRP
- B. VRID is set automatically as SVI vlan id
- C. VRRP and Active gateway are mutually exclusive on a VLAN
- D. VRRP and Active Gateway can be configured on a single VLAN for interoperability
Answer: C
Explanation:
Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network. If you have enabled active gateway, VRRP is not required3. Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches. The switch views the active gateway IP as a self IP address3. Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network3. Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.
NEW QUESTION # 40
Refer to the image.
Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7
- A. The AP is configured in Mesh mode
- B. The AP is a remote access point.
- C. The AP is using a directional antenna.
- D. The AP is an outdoor access point.
Answer: C
Explanation:
Explanation
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna.
A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

NEW QUESTION # 41
A customer wants to provide wired security as close to the source as possible The wired security must meet the following requirements:
-allow ping from the IT management VLAN to the user VLAN
-deny ping sourcing from the user VLAN to the IT management VLAN
The customer is using Aruba CX 6300s
What is the correct way to implement these requirements?
- A. Apply an inbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- B. Apply an inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
- C. Apply an outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
- D. Apply an outbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
Answer: A
Explanation:
An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5.

NEW QUESTION # 42
Which statements are true about VSX LAG? (Select two.)
- A. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
- B. Outgoing traffic is preferentially switched to local members of the LAG.
- C. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
- D. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.
- E. The total number of configured links may not exceed 8 for the pair or 4 per switch
Answer: B,E
Explanation:
Explanation
The correct answers are A and D.
According to the web search results, VSX LAG is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices1. VSX LAGs span both aggregation switches and appear as one device to partner downstream or upstream devices or both when forming a LAG with the VSX pair2.
One of the statements that is true about VSX LAG is that the total number of configured links may not exceed
8 for the pair or 4 per switch1. This means that a VSX LAG across a downstream switch can have at most a total of eight member links, and a switch can have a maximum of four member links. When creating a VSX LAG, it is recommended to select an equal number of member links in each segment for load balancing1.
Another statement that is true about VSX LAG is that outgoing traffic is preferentially switched to local members of the LAG2. This means that when active forwarding and active gateway are enabled, north-south and south-north traffic bypasses the ISL link and uses the local ports on the switch. This optimizes the traffic path and reduces the load on the ISL link2.
The other statements are false or not relevant for VSX LAG. Outgoing traffic is not switched to a port based on a hashing algorithm, which may be either switch in the pair. This is a characteristic of MLAG (Multi-Chassis Link Aggregation), which is a different feature from VSX LAG. LAG traffic is not passed over VSX ISL links only while upgrading firmware on the switch pair. This is a scenario that may occur when performing hitless upgrades, which is a feature that allows software updates without impacting network availability. The number of VSX lags that can be configured on all 83xx and 84xx model switches is not 255, but depends on the switch model and firmware version. For example, the AOS-CX 10.04 supports up to 64 VSX lags for 8320 switches and up to 128 VSX lags for 8325 and 8400 switches.
NEW QUESTION # 43
You need to drop excessive broadcast traffic on an ingress port or an ArubaOS-CX switch. What is the best feature to use for this task?
- A. QoS shaping
- B. Rate limiting
- C. DWRR queuing
- D. Strict queuing
Answer: B
Explanation:
According to the Aruba Documentation Portal1, the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.
This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second. Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port

NEW QUESTION # 44
What is a primary benefit of BSS coloring?
- A. BSS color tags improve security by identifying rogue APs and removing them from the network.
- B. BSS color tags are applied to client devices and can reduce the threshold for interference
- C. BSS color tags improve performance by allowing clients on the same channel to share airtime.
- D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
Answer: D
Explanation:
BSS coloring is a mechanism that helps identify the BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. on the same channel and differentiate them from other BSS on the same channel12. Each BSS is assigned a color code, which is a 6-bit value that is carried in the PHY header of the Wi-Fi frames12. By using BSS coloring, the APs and clients can reduce the threshold for interference detection and avoid unnecessary backoff or retransmissions when they detect frames from other BSS with different colors12. This can improve the spectral efficiency and throughput of the network12. The other options are incorrect because they do not describe the primary benefit of BSS coloring.

Refer to Exhibit:
A company has deployed 200 AP-635 access points. To take advantage of the 6 GHz band, the administrator has attempted to configure a new WPA3-OWE SSID in Central but is not working as expected.
What would be the correct action to fix the issue?
- A. Change the SSID to WPA3-Enterprise (CCM).
- B. Change the SSID to WPA3-Personal.
- C. Change the SSID to WPA3-Enhanced Open.
- D. Change the SSID to WPA3-Enterprise (CNSA).
Answer: C
Explanation:
The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.
WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:
Select the Security Level from the drop-down list. The following options are available:
WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.
WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.
WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.
WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.
The other options are incorrect because:
A) WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
B) WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company's use case.
D) WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.

For the Aruba CX 6400 switch, what does virtual output queueing (VOQ) implement that is different from most typical campus switches?
- A. large ingress packet buffers
- B. VSX
- C. large egress packet buffers
- D. per port ASICs
Answer: A
Explanation:
Explanation
The Aruba CX 6400 switch is a modular switch that supports high-performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ). VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of-line blocking and packet loss due to congestion2. VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class2. VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and scenarios. References: 2

You are setting up a customer's 15 headless loT devices that do not support 802.1X. What should you use?
- A. Multiple Pre-Shared Keys (MPSK) Local
- B. Clearpass with WPA3-AES
- C. Clearpass with WPA3-PSK
- D. Multiple Pre-Shared Keys (MPSK) with WPA3-AES
Answer: A
Explanation:
Explanation
MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

You are helping an onsite network technician bring up an Aruba 9004 gateway with ZTP for a branch office The technician was to plug in any port for the ZTP process to start Thirty minutes after the gateway was plugged in new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is 172.16 0.81 However, the branch office network is supposed to be on 10.231 81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?
- A. Move the cable on the gateway from port G0/0V1 tc port G0 0.0
- B. Move the cable on the gateway to G0/0/1. and add the device's MAC and Serial number in Central
- C. Factory default and reboot the gateway to restart the process.
- D. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
Answer: A
Explanation:
Explanation
Aruba 9004 gateway supports ZTP on port G0/0/0 by default1. If the gateway is connected to a different port, such as G0/0/V1, it will not be able to communicate with Aruba Activate and Aruba Central, which are required for ZTP2. Moreover, port G0/0/V1 is configured as a DHCP server by default, which can cause IP address conflicts with the existing network3. Therefore, the technician should move the cable on the gateway to port G0/0/0, which will allow the gateway to obtain an IP address from the network DHCP server and start the ZTP process. The other options are not correct because they will not solve the issue or enable ZTP. For example, option D will not work because factory defaulting and rebooting the gateway will not change the port configuration or behavior3.
