ACMA Configuration & Troubleshooting of Aruba Solutions 4

Question 1

An admin wants to configure port-based 802.1X authentication on an Aruba switch uplink port. Which port mode should be avoided for this configuration?

Accepted Answer

Trunk mode

Answer

802.1X port-based authentication is not applicable to trunk ports, which carry multiple VLANs between infrastructure devices and do not authenticate end users.

Question 2

In ArubaOS, what does the 'aaa profile' bind together for a given SSID?

Accepted Answer

Authentication method, server group, and default user role

Answer

An AAA profile links the authentication method (802.1X, MAC, captive portal), the RADIUS server group, and the default role assigned to authenticated users.

Question 3

A client successfully connects to an Aruba SSID but cannot reach the internet. The 'show user' command shows the client in the 'logon' role. What does this indicate?

Accepted Answer

Authentication has not completed; the client is in the pre-authentication role

Answer

The 'logon' role is the default pre-authentication role; if a client remains there, it means authentication (802.1X, captive portal, or MAC auth) has not succeeded.

Question 4

When deploying Aruba Central for cloud management, which protocol does the AP use to establish its management tunnel to Aruba Central?

Accepted Answer

HTTPS over port 443

Answer

Aruba APs managed by Aruba Central use HTTPS (port 443) to establish the management connection to the cloud platform.

Question 5

An Aruba controller shows high CPU utilization. An admin suspects rogue AP processing is consuming resources. Which command would help identify the number of rogues being tracked?

Accepted Answer

show ap monitor ap-list | count

Answer

Piping 'show ap monitor ap-list' through count reveals how many neighboring APs are being tracked, which directly impacts CPU load from rogue processing.
