ACP Network Management and Troubleshooting 3

Question 1

Which Aruba tool provides AI-driven anomaly detection and root-cause analysis for wireless performance degradation?

Accepted Answer

Aruba AIOps in Central

Answer

Aruba AIOps (within Aruba Central) uses machine learning to detect network anomalies and provides root-cause analysis with remediation suggestions.

Question 2

A technician needs to verify that OSPF adjacencies are forming correctly on an Aruba switch. Which command provides this information?

Accepted Answer

show ip ospf neighbor

Answer

'show ip ospf neighbor' displays the state of all OSPF neighbor relationships including their current FSM state (e.g., FULL, 2WAY).

Question 3

In Aruba Instant (IAP) deployments, what happens to client connectivity if the Virtual Controller AP goes offline?

Accepted Answer

A new VC is automatically elected from remaining APs and clients reconnect

Answer

Aruba Instant uses an automatic VC election process; when the current VC fails, the remaining APs elect a new VC within seconds and client services resume.

Question 4

Which syslog severity level should be configured to capture authentication failures without overwhelming storage with debug messages in Aruba OS?

Accepted Answer

Level 6 (Informational)

Answer

Syslog level 6 (Informational) captures authentication events and general operational messages without the volume overhead of Debug-level logging.

Question 5

A roaming client on an Aruba network experiences a 2-second interruption every time it moves between APs. Which feature, when enabled, would most reduce this roaming latency?

Accepted Answer

Opportunistic Key Caching (OKC) / PMK caching

Answer

OKC (Opportunistic Key Caching) allows clients to reuse cached PMKs when roaming between APs on the same controller, eliminating the full 802.1X re-authentication delay.
