An administrator wants to monitor real-time traffic flows on an Aruba switch without impacting production traffic. Which feature should they use?
Answer: Port mirroring (SPAN)
Port mirroring (SPAN) copies traffic from a source port to a monitor port in real time without impacting the forwarded traffic.
Which SNMPv3 security level provides both authentication and encryption?
Answer: authPriv
authPriv uses both an authentication protocol (MD5 or SHA) and a privacy protocol (DES or AES) to secure SNMP communications.
A network engineer needs to track when interfaces go up or down on Aruba switches. What is the most efficient method?
Answer: Configuring SNMP traps for linkUp and linkDown events
SNMP traps send immediate event-driven notifications when interface state changes occur, eliminating the latency and overhead of polling.
Which Aruba Central feature allows an administrator to set up automated alerts when a switch CPU exceeds a defined threshold?
Answer: Threshold-based alerts in the Alerts & Events module
Aruba Central's Alerts & Events module allows configuring threshold-based alerts that trigger notifications when metrics like CPU utilization exceed defined limits.
What does the 'debug destination' command control on an Aruba switch?
Answer: Where debug log output is sent (session, syslog, or buffer)
The 'debug destination' command specifies where debug output is directed, such as to the current session, a buffer, or a syslog server.
Which protocol does Aruba AirWave use to collect performance data from managed switches?
Answer: SNMP
AirWave uses SNMP to collect device performance metrics, interface statistics, and configuration data from managed Aruba switches.
An Aruba switch is generating excessive syslog messages. Which command limits syslog to only critical and above messages?
Answer: logging severity critical
The 'logging severity critical' command filters syslog output to only transmit messages at the critical severity level (2) and above (emergency, alert).
