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 improve performance by allowing clients on the same channel to share airtime.
- C. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
- D. BSS color tags are applied to client devices and can reduce the threshold for interference
Answer: D
Explanation:
Explanation
This is the correct definition of BSS coloring and its primary benefit. BSS coloring is a mechanism that assigns a color code to each BSS (Basic Service Set), which consists of an AP and its associated clients. The color code is added to the PHY header of each frame transmitted by the AP or the client. BSS coloring helps reduce co-channel interference by allowing devices to differentiate between frames from their own BSS and frames from neighboring BSSs that use the same channel. Devices can then adjust their threshold for interference based on the color code and decide whether to transmit or defer based on the channel status. The other options are incorrect because they either describe different mechanisms or benefits of BSS coloring or use incorrect terms. References:

NEW QUESTION # 19
With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?
- A. Sixteen different VMACS are supported for each IPV4 and IPV6 stack simultaneously
- B. copied over the ISL link for an optimized path.
- C. Active Gateway can once MSTP instances are created for VLAN load sharing.
- D. Sixteen different VMACs are supported total as shared.
Answer: A
Explanation:
Explanation
The active gateway feature is used to provide active-active layer 3 default gateway for hosts on the same subnet. It allows the switch to convert multicast streams into unicast streams over the wireless link, which improves the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. The active gateway feature is unique to VSX configuration because it eliminates the need for VRRP and avoids traffic being pushed over the ISL link, which can cause latency in the network12.
The correct answer to the question is C. Sixteen different VMACs are supported for each IPv4 and IPv6 stack simultaneously. This means that you can have a maximum of eight VMACs for IPv4, and a maximum of eight VMACs for IPv6, on a VSX pair. Only 15 VMACs are supported on 6400 switch series2.
The other options are incorrect because:
A: Sixteen different VMACs are not supported total as shared. They are supported for each IPv4 and IPv6 stack separately.
B: Active gateway can be used without MSTP instances. MSTP is a protocol that allows multiple spanning tree instances to coexist on the same switch, but it does not affect how active gateway works.
D: Active gateway does not copy traffic over the ISL link for an optimized path. It avoids using the ISL link for routed traffic and uses the local switch interface MAC instead of the virtual MAC address (VMAC) for source address1.

NEW QUESTION # 21
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 denying icmp echo traffic toward the IT management VLAN
- D. Apply an outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
Answer: A
Explanation:
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. References: 4

- 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:
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. References:

NEW QUESTION # 24
You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the "show arp" command on the primary switch in the pair but do not find a matching entry for the client MAC address.
The client device is connected to an Aruba CX 6100 switch by VSX LAG.
Which action can be used to find the IP address successfully?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
The show arp command displays the ARP table for a specific VRF or all VRFs on the switch. The ARP table contains the IP address to MAC address mappings for hosts that are directly connected to the switch or reachable through a gateway. If the client device is connected to another switch by VSX LAG, the ARP entry for the client device will not be present on the primary switch unless it has communicated with it recently. Therefore, to find the IP address of the client device, the administrator should run the show arp command on the secondary switch in the VSX pair, specifying the VRF name that contains the client device's subnet.

- A. MAC Caching under the WLAN
- B. Wireless Caching under the splash page
- C. MAC Caching under the splash page
- D. MAC Caching under the user-role
Answer: A
Explanation:
Explanation
This is the correct solution to deal with the issue where visitors keep complaining that the captive portal page keeps coming up after devices go to sleep. MAC Caching is a feature that allows an Aruba Access Point to bypass authentication for devices that have already been authenticated by a captive portal. MAC Caching can be enabled under the WLAN settings in Aruba Cloud Guest by selecting the MAC Caching checkbox and specifying the MAC Caching duration. The other options are incorrect because they either do not exist or do not apply to Aruba Cloud Guest. References:

NEW QUESTION # 26
You are are doing tests in your lab and with the following equipment specifications:
* AP1 has a radio that generates a 16 dBm signal.
* AP2 has a radio that generates a 13 dBm signal.
* AP1 has an antenna with a gain of 8 dBi.
* AP2 has an antenna with a gain of 12 dBi. The antenna cable for AP1 has a 4 dB loss. The antenna cable for AP2 has a 3 dB loss.
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for AP1?
- A. -9 dBm
- B. 40 dBm
- C. 20 dBm
- D. 15 dBm
Answer: C
Explanation:
The Equivalent Isotropic Radiated Power (EIRP) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB2. The formula for EIRP is:
EIRP=PT−Lc+Ga
where PT is the output power of the transmitter in dBm, Lc is the cable and connector loss in dB, and Ga is the antenna gain in dBi.
For AP1, the EIRP can be calculated as:
EIRP=16−4+8=20 dBm
Therefore, the answer B is correct.
NEW QUESTION # 27
A system engineer needs to preconfigure several Aruba CX 6300 switches that will be sent to a remote office An untrained local field technician will do the rollout of the switches and the mounting of several AP-515s and AP-575S. Cables running to theAPs are not labeled.
The VLANs are already preconfigured to VLAN 100 (mgmt), VLAN 200 (clients), and VLAN 300 (guests) What is the correct configuration to ensure that APs will work properly?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Explanation
Option C is the correct configuration to ensure that APs will work properly. It uses the ap command to configure a port profile for APs with VLAN 100 as the native VLAN and VLAN 200 and 300 as tagged VLANs. It also enables LLDP on the ports to discover the APs and assign them to the port profile automatically. The other options are incorrect because they either do not use the ap command, do not enable LLDP, or do not configure the VLANs correctly. References:

The other options either use more commands or do not create the VRF or the VLAN.
Option C uses the following commands:
vrf eng: This command creates a VRF named eng and enters the VRF configuration mode1.
vlan 25: This command creates a VLAN with ID 25 and enters the VLAN configuration mode2.
interface vlan 25: This command creates an SVI on VLAN 25 and enters the interface configuration mode3.
ip address 10.105.43.1/24 ipv6 address fd00:5780::102d:4df6/64 vrf attach eng: This command assigns an IPv4 address of 10.105.43.1 with a subnet mask of 255.255.255.0 and an IPv6 address of fd00:5780::102d:4df6 with a prefix length of 64 to the SVI, and attaches it to the VRF eng.
NEW QUESTION # 29
The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration
What is the most likely cause of this issue?
- A. There is a mismatch between the RADIUS secret on the switch and CPPM.
- B. The SSL certificate for CPPM has not been added as a trust point on the switch
- C. Change of Authorization has not been globally enabled on the switch
- D. There is a time difference between the switch and the ClearPass Policy Manager
Answer: C
Explanation:
Explanation
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated. References:

NEW QUESTION # 30
What is true regarding 802.11k?
- A. It extends radio measurements to define mechanisms for wireless network management of stations
- B. It reduces roaming delay by pre-authenticating clients with multiple target APs before a client roams to an AP
- C. It provides mechanisms for APs and clients to dynamically measure the available radio resources.
- D. It considers several metrics before it determines if a client should be steered to the 5GHz band, including client RSSI
Answer: C
Explanation:
802.11k is a standard that provides mechanisms for APs and clients to dynamically measure the available radio resources in a wireless network. 802.11k defines radio resource management (RRM) functions, such as neighbor reports, link measurement, beacon reports, etc., that allow APs and clients to exchange information about the RF environment and make better roaming decisions. The other options are incorrect because they describe other standards, such as 802.11r, 802.11v, or 802.11ax.

NEW QUESTION # 33
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 GO 0.0
- B. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
- C. Move the cable on the gateway to G0/0/1. and add the device's MAC and Serial number in Central
- D. Factory default and reboot the gateway to restart the process.
Answer: C
Explanation:
Explanation
This is the correct action to alleviate the issue and get the ZTP (Zero Touch Provisioning) process started correctly for an Aruba 9004 gateway. ZTP is a feature that allows an Aruba gateway to automatically download its configuration from Aruba Central without any manual intervention. To use ZTP, the gateway must be connected to a DHCP-enabled network and have Internet access. The gateway must also be added to Aruba Central using its MAC address and serial number. The default port for ZTP on an Aruba 9004 gateway is G0/0/1, which is labeled as Internet on the device. The other options are incorrect because they either do not use the correct port for ZTP or do not add the device to Aruba Central. References:
