HP HPE7-A01 Practice Test 7
Question 60
An AP is adopted into a management inventory but inherits a remote site's SSID settings because its assigned configuration group is wrong. The change fails acceptance. What is the safest targeted restoration action?
- Restore the previous correct scope mapping and lease parameters, then renew a test client before wider rollout.
- Restore the previous valid RA and gateway configuration while protecting the segment from rogue router advertisements.
- Return the patch to the documented known-good uplink and restore accurate port inventory if the change fails.
- Move the AP back to its known-good group and restore last published site configuration if the reassignment fails.
Explanation
Correct Answer
D:Move the AP back to its known-good group and restore last published site configuration if the reassignment fails. Central device enrollment and effective configuration group are separate steps; wrong scope can apply valid settings to the wrong site. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described access point assignment to site and group situation.
Incorrect Answers
A:Restore the previous correct scope mapping and lease parameters, then renew a test client before wider rollout. This instead concerns ipv4 subnet and gateway correctness. A host needs coherent subnet membership and gateway information; link-up cannot compensate for an incorrect prefix or default router. It would not safely roll back the relevant failed change. The immediate problem concerns access point assignment to site and group.
B:Restore the previous valid RA and gateway configuration while protecting the segment from rogue router advertisements. This instead concerns ipv6 ra and default-router discovery. IPv6 clients commonly learn prefixes and default-router presence from RAs; IPv4 DHCP success does not validate that control plane. It would not safely roll back the relevant failed change. The immediate problem concerns access point assignment to site and group.
C:Return the patch to the documented known-good uplink and restore accurate port inventory if the change fails. This instead concerns lldp neighbor identification. LLDP exposes directly connected device identifiers, helping distinguish mispatching from routing or WLAN failures without guessing topology. It would not safely roll back the relevant failed change. The immediate problem concerns access point assignment to site and group.
Question 61
A replacement AP reports online in Aruba Central but does not advertise the intended campus WLAN after being placed in a lab group. Before implementing a remedy, what should the engineer check first?
- Cross-check host address and prefix, default gateway, switch VLAN and the gateway interface's network assignment.
- Review ICMPv6 router advertisements, RA flags, prefix information and default-route installation at the client.
- Review AP serial identity, selected site or group and effective inherited configuration before changing radios.
- Review LLDP neighbor identifiers, chassis and port IDs and the physical patching record for the affected link.
Explanation
Correct Answer
C:Review AP serial identity, selected site or group and effective inherited configuration before changing radios. Central device enrollment and effective configuration group are separate steps; wrong scope can apply valid settings to the wrong site. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described access point assignment to site and group situation.

The immediate problem concerns access point assignment to site and group.
D:Review LLDP neighbor identifiers, chassis and port IDs and the physical patching record for the affected link. This instead concerns lldp neighbor identification. LLDP exposes directly connected device identifiers, helping distinguish mispatching from routing or WLAN failures without guessing topology. It does not isolate the cause of the stated incident. The immediate problem concerns access point assignment to site and group.
Question 62
A replacement AP reports online in Aruba Central but does not advertise the intended campus WLAN after being placed in a lab group. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Cross-check host address and prefix, default gateway, switch VLAN and the gateway interface's network assignment.
- Review AP serial identity, selected site or group and effective inherited configuration before changing radios.
- Activate appropriate authorized IPv6 RA behavior on the correct gateway interface with intended prefix and policy.
- Map the AP to the correct device group and apply the intended approved WLAN configuration.
Explanation
Correct Answers
B:Review AP serial identity, selected site or group and effective inherited configuration before changing radios.

Question 63
A replacement AP reports online in Aruba Central but does not advertise the intended campus WLAN after being placed in a lab group. A deployment job reports success. Which observed result would actually validate the affected service?
- Confirm the AP's effective settings, advertised SSIDs and client association to the target site match the design.
- Choose host route inspection and successful traffic to both local and remote approved destinations as proof.
- Verify the client installs the intended IPv6 prefix and default route and reaches a permitted external IPv6 endpoint.
- Validate bidirectional neighbor advertisements and match learned port IDs to the approved topology map for the affected campus deployment.
Explanation
Correct Answer
A:Confirm the AP's effective settings, advertised SSIDs and client association to the target site match the design.
