QUESTION: 29

A campus topology uses VSX with a collapsed core topology. The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link. You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.

What is a valid configuration?

A)

B)

C)

D)

Option A
Option B
Option C
Option D

Answer(s): A

Explanation:

The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC- LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.

QUESTION: 30

A customer is running out of IP addresses in a network segment.
What will happen If they add an additional IPsubnet to the same VLAN?

Broadcasts for me two subnets win arrive on all ports in the same VLAN
IGMP will not work in both of the subnets in the same VLAN
This would result in a single SVI using two subinterfaces.
Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN

Answer(s): D

Explanation:

Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.

QUESTION: 31

in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking

Central:

The customer asks you to investigate log messages What should you tell them?

This indicates a security issue. The client with a MAC address ending with 37 18;0d Is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network.
This is normal, expected behavior. No further actions are needed.
This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18 :Od. You should upgrade the client WLAN driver.
There is a roaming issue Enable Fast Roaming 802.11r and OKC to resolve the issue.

Answer(s): B

Explanation:

The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.

QUESTION: 32

A customer has deployed an AOS 10 mobility gateway cluster consisting of three controllers at a single site The WLAN is configured to tunnel wireless device traffic to the AOS 10 mobility cluster The clients are authenticated by ClearPass using WPA3-Enterprise (opmode wpa3-aes-ccm-128). The security team has requested the ability to force a wireless device to reauthenticate using ClearPass.
Which steps are required to ensure ClearPass can consistently initiate a change of authorization against an AOS 10 mobility cluster, including during gateway failover scenarios? (Select two)

set cluster mode to Auto Site under High Availability - Cluster configuration
modify WLAN - SSID - VLAN - Mode Configuration
enable manual cluster configuration under High Availability - Cluster Configuration
enable Dynamic Authorization CoA under High Availability - Cluster Configuration
modify NAS IPv4 address under Security - Advanced - RADIUS Client

Answer(s): D,E

Explanation:

To ensure that ClearPass can initiate a Change of Authorization (CoA) consistently, it's important to enable dynamic authorization to allow RADIUS CoA messages to be processed. This setting typically falls under the high-availability cluster configuration to ensure that it persists across gateway failovers. Additionally, the NAS IP address must be configured under RADIUS client settings to ensure that the correct IP address is used for RADIUS communications, which is necessary for CoA to function correctly.
