NEW QUESTION # 86
You need to configure four uplinks between an AOS-CX access and aggregation switch. Which HPE Aruba Networking Central configuration method should you use?
Answer: C
Explanation:
Technical explanation
Use LACP to bundle four physical uplinks into one logical LAG, with consistent speeds, VLAN configuration and link settings on both endpoints. The port-channel distributes traffic across members according to a hashing algorithm, so a single conversation does not necessarily multiply its own throughput by four. The bundle also preserves connectivity when one member fails if sufficient links remain active. Verify the partner system ID, active member count, collecting/distributing state and any minimum-links requirement before production cutover. The aggregate offers more total bandwidth, but any single flow may remain limited to one physical member depending on the hash. Confirm matching LACP mode, allowed VLANs and MTU at both ends.
Turning off STP on four unmanaged parallel L2 links creates an obvious loop risk. Four independent VLAN access ports do not aggregate throughput for the same logical connection. LACP forms one port-channel and detects member mismatches.

NEW QUESTION # 87
A retail branch needs POS traffic to be forwarded locally but guest traffic forwarded through a Gateway located in a DMZ. Which SSID mode meets this requirement?
Answer: C
Explanation:
Technical explanation
A mixed-mode SSID supports both bridged and tunneled forwarding, selected according to the client VLAN and deployment configuration. Put POS endpoints in the locally bridged role/VLAN where latency-sensitive branch processing must remain onsite; tunnel the guest VLAN toward a DMZ gateway cluster where centralized inspection is required. Ensure guest VLANs terminate on gateways and are not accidentally carried onto the AP's local switching trunk. Mixed mode is not arbitrary per-packet application steering; the forwarding selection must match the actual WLAN/VLAN policy. Under mixed forwarding, the relevant VLAN assignment decides the datapath. Ensure POS VLANs are permitted on the local AP uplink, while the guest VLAN is present on the gateway cluster for tunneling.
All-tunnel forwarding would backhaul the POS transactions unnecessarily; all-bridge forwarding would bypass the DMZ gateway for guests. Mixed forwarding is selected per VLAN/client role, so different VLANs require the intended bridge/tunnel mapping and uplink support. The AOS-10 WLAN wizard exposes Traffic Forwarding Mode = Mixed in its VLAN settings, with a primary gateway cluster for tunneled VLANs.

NEW QUESTION # 88
HPE Aruba Networking Central shows repeated "EAP timeout" errors. What's the first step to confirm the cause?
Answer: A
Explanation:
Technical explanation
An EAP timeout indicates that an expected authentication message or reply did not arrive within its timer; it is not equivalent to an explicit credential rejection. Verify that the gateway or appropriate AP can reach the configured RADIUS server over the correct network, that shared credentials are valid and that UDP 1812 or configured RadSec connectivity functions. Inspect server logs for received requests and response latency.
Only after establishing transport health should you inspect user accounts, certificates or EAP-method mismatches.
An "EAP timeout" is a lack of a timely authentication response, not inherently a bad password; credential failures usually create a rejection. Replacing certificates without checking network reachability can destroy useful evidence and does not restore an unreachable server. If RADIUS requests leave the gateway but responses are absent, check firewall rules, shared-secret configuration and server processing. If a timely Access-Reject returns instead, move the investigation to credentials or authorization.

NEW QUESTION # 89
You need to capture a sequence of diagnostic actions for audit. Which Troubleshoot feature preserves prior runs for later review?
Answer: B
Explanation:
The Troubleshoot tool within HPE Aruba Networking Central includes a dedicated History tab designed for auditing and continuity. When diagnostic tests or CLI command sessions are executed, the results are not volatile; instead, they are archived in this tab with associated timestamps and device details. This allows administrators to revisit the exact output of previous troubleshooting sessions, compare results over time, and provide documented evidence of diagnostic actions for audit purposes.

Which Aruba Central feature helps predict potential network problems before they occur?
Answer: B
Explanation:
AIOps Predictive Insights analyzes trends and historical telemetry data to proactively identify conditions that could lead to future network issues.
