Which ArubaOS-CX feature allows administrators to write custom Python scripts that react to network events and automatically remediate issues?
Answer: Network Analytics Engine (NAE)
NAE on ArubaOS-CX enables Python-based monitoring agents that can trigger automated actions in response to network events and threshold violations.
An Aruba switch is configured with SNMP but the NMS is not receiving traps. Which configuration element is most likely missing?
Answer: SNMP trap receiver host address and version
SNMP traps require the trap receiver's IP address and SNMP version to be explicitly configured on the switch; without this, traps have no destination.
What is streaming telemetry's primary advantage over traditional SNMP polling for network monitoring?
Answer: It pushes data continuously in real time rather than requiring periodic requests
Streaming telemetry uses a push model to deliver continuous, high-frequency operational data to collectors, providing lower latency visibility than poll-based SNMP.
Which protocol does ArubaOS-CX use for streaming telemetry to modern monitoring platforms?
Answer: gRPC with OpenConfig or gNMI
ArubaOS-CX supports gRPC-based streaming telemetry using OpenConfig data models and gNMI (gRPC Network Management Interface) for integration with modern collectors.
A switch administrator wants to identify which MAC addresses are present on each VLAN. Which command provides this on an Aruba switch?
Answer: show mac-address-table vlan
The 'show mac-address-table vlan ' command displays all MAC addresses learned on the specified VLAN along with their associated ports.
What does the 'show logging' command display on an Aruba switch?
Answer: Buffered syslog messages stored in the switch's memory
The 'show logging' command displays the syslog messages that have been stored in the switch's internal logging buffer.
An engineer configures port mirroring on an Aruba switch but notices the monitor port is dropping packets. What is the most likely cause?
Answer: The mirrored traffic volume exceeds the monitor port bandwidth
When mirrored traffic from high-speed or multiple source ports exceeds the capacity of the monitor port, packet drops occur at the destination port.
