ACMA Configuration & Troubleshooting of Aruba Solutions 2

Question 1

An administrator needs to configure a VLAN on an Aruba switch to carry traffic for multiple SSIDs. Which command correctly creates VLAN 20 and assigns it a name?

Accepted Answer

vlan 20 name Corporate

Answer

The command 'vlan 20 name Corporate' is the correct ArubaOS-Switch syntax to create VLAN 20 and assign it the name Corporate.

Question 2

A wireless client is associated but cannot obtain an IP address. The SSID is mapped to VLAN 30. What is the first troubleshooting step?

Accepted Answer

Verify the DHCP server has a scope for VLAN 30

Answer

If a client associates successfully but cannot get an IP, verifying that a DHCP scope exists for the mapped VLAN is the first logical step.

Question 3

Which Aruba CLI command displays the current status and configuration of all SSIDs broadcast by an AP?

Accepted Answer

show ap bss-table

Answer

'show ap bss-table' lists all BSSIDs and their associated SSIDs currently being broadcast by Aruba APs.

Question 4

A new Aruba IAP is powered on but does not appear in the Instant network. The AP has an IP address via DHCP. What should be checked next?

Accepted Answer

Verify the AP can reach the Virtual Controller IP on UDP 8211

Answer

Aruba Instant APs discover and join the Virtual Controller using UDP port 8211; a firewall blocking this port prevents cluster formation.

Question 5

When configuring WPA3-SAE on an Aruba controller, what must also be enabled to support legacy WPA2 clients simultaneously?

Accepted Answer

WPA3 Transition Mode (SAE Mixed)

Answer

WPA3 Transition Mode (SAE Mixed) allows both WPA2-PSK and WPA3-SAE clients to connect to the same SSID simultaneously.
