NEW QUESTION # 79
You need to capture a sequence of diagnostic actions for audit. Which Troubleshoot feature preserves prior runs for later review?
Answer: B
Explanation:
Technical explanation
Run tests and, where authorized, command sessions from Troubleshooting so their timestamps, device context and results appear in History. The session record allows comparison before and after an intervention and can be exported as operational evidence. For accountability, also consult Audit Trail, which records administrative actions rather than being a substitute for diagnostic output. Preserve results externally when a regulatory or investigation retention period exceeds Central's operational history retention window. Central records troubleshooting sessions under Troubleshoot > History; select a session ID to read its outputs and any associated notes.
A configuration-change event cannot replay the output of a cable test or ping. The site timeline helps correlate incidents but is not a test archive. History contains prior sessions and can be reviewed for repeated diagnostics or handover.

NEW QUESTION # 80
A downlink reports flapping. Which Troubleshoot tool provides a guided test you can run from HPE Aruba Networking Central to validate physical health?
Answer: B
Explanation:
Technical explanation
Launch the Tests tab for the affected switch, select Cable Test and target the reported downlink interface.
Interpret pair status and estimated distance in conjunction with switch port logs and NIC/transceiver behavior.
A cable test is most useful for compatible copper media; optical links require optics diagnostics and error counters instead. Changing speed/duplex blindly can introduce mismatches, and administrative shutdown destroys evidence of intermittent negotiation problems. Schedule potentially disruptive cable diagnostics around user impact.
Changing port speed and duplex before testing can create a new negotiation mismatch. Disabling a port via remote console only proves it stops forwarding. The purpose of the cable test is to interrogate the suspect copper pair while preserving diagnostic evidence. Use the affected device's Troubleshoot > Tests workflow and choose Cable Test where the port and platform support it.

NEW QUESTION # 81
You are consolidating LAN and WLAN administration into one platform. Which HPE Aruba Networking Central capability will achieve the goal to manage all domains from a unified interface?
Answer: A
Explanation:
HPE Aruba Networking Central provides a single pane of glass to manage access points, switches, and gateways from one unified interface. This consolidated view enables centralized configuration, monitoring, and policy management across both LAN and WLAN domains, simplifying operations and improving visibility.
NEW QUESTION # 82
HPE Aruba Networking Central flags "High Retry Rate on 5 GHz." What's the best next action?
Answer: A
Explanation:
Technical explanation
High 5 GHz retries can reflect co-channel interference, hidden nodes, low SNR, weak client transmit power or congestion even when an AP advertises adequate signal. Expand the performance card to compare channel utilization, noise, retries, PHY rates and client distribution over the relevant interval. Only then decide whether RF optimization, an AP placement change or a client-side fix is justified. Forcing clients to 2.4 GHz may worsen contention, and disabling band steering removes a steering mechanism without addressing underlying airtime loss.
Moving everyone to 2.4 GHz might simply exchange a noisy 5 GHz channel for a more congested band. Band steering changes client preference, not the cause of retries. First determine whether utilization, signal quality, or interference correlates with retries.

NEW QUESTION # 83
Clients report brief outages overnight. Which dashboard element helps correlate events with time windows to identify root cause?
Answer: C
Explanation:
Technical explanation
Select the interval matching the overnight complaint and inspect event timestamps against authentication failures, DHCP activity, uplink transitions, AP restarts and configuration pushes. Correlating several event categories avoids mistaking the symptom for its cause. For example, multiple client disconnects coinciding with a PoE switch reboot indicate a likely shared infrastructure problem, not dozens of individual WLAN faults. Remember that dashboards may aggregate or delay telemetry; use raw device logs or system audit records when minute-level ordering matters.
A neighbor count reports adjacency, not the precise start and end of an incident. Subscription expiry is useful for licensing administration but cannot explain a ten-minute night-time interruption unless associated with specific device events.
