HP HPE7-A01 Practice Test 6
Question 50
An AOS-CX switch uses a dedicated management interface but a new remote-access ACL accidentally admits guest-subnet SSH sessions. Which specific corrective design step best meets the stated campus requirement?
- Place management traffic in the approved dedicated interface or VRF and constrain permitted administrator sources.
- Assign the AP to the correct device group and apply the intended approved WLAN configuration.
- Correct the host's DHCP scope or static configuration so address, prefix and gateway belong to the intended subnet.
- Enable appropriate authorized IPv6 RA behavior on the correct gateway interface with intended prefix and policy.
Explanation
Correct Answer
A:Place management traffic in the approved dedicated interface or VRF and constrain permitted administrator sources. Data-plane connectivity and administrative reachability serve different trust boundaries; a dedicated management design restricts who can configure devices. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described management vlan access isolation situation.
Incorrect Answers
B:Assign the AP to the correct device group and apply the intended approved WLAN configuration. This instead concerns access point assignment to site and group. Central device enrollment and effective configuration group are separate steps; wrong scope can apply valid settings to the wrong site. It would not implement the specifically required change. The immediate problem concerns management vlan access isolation.
C:Correct the host's DHCP scope or static configuration so address, prefix and gateway belong to the intended subnet. 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 implement the specifically required change. The immediate problem concerns management vlan access isolation.
D:Enable appropriate authorized IPv6 RA behavior on the correct gateway interface with intended prefix and policy. 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 implement the specifically required change. The immediate problem concerns management vlan access isolation.
Question 51
An AOS-CX switch uses a dedicated management interface but a new remote-access ACL accidentally admits guest-subnet SSH sessions. Following a targeted change, which acceptance test would most directly demonstrate success?
- Verify the AP's effective settings, advertised SSIDs and client association to the target site match the design.
- Use host route inspection and successful traffic to both local and remote approved destinations as proof.
- Confirm the client installs the intended IPv6 prefix and default route and reaches a permitted external IPv6 endpoint.
- Verify approved NOC sessions succeed and blocked campus-client sources cannot reach management services.
Explanation
Correct Answer
D:Verify approved NOC sessions succeed and blocked campus-client sources cannot reach management services. Data-plane connectivity and administrative reachability serve different trust boundaries; a dedicated management design restricts who can configure devices. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described management vlan access isolation situation.
Incorrect Answers
A:Verify the AP's effective settings, advertised SSIDs and client association to the target site match the design. This instead concerns access point assignment to site and group. Central device enrollment and effective configuration group are separate steps; wrong scope can apply valid settings to the wrong site. It would not establish that this function actually works. The immediate problem concerns management vlan access isolation.
B:Use host route inspection and successful traffic to both local and remote approved destinations as proof. 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 establish that this function actually works. The immediate problem concerns management vlan access isolation.

The immediate problem concerns management vlan access isolation.
Question 52
An AOS-CX switch uses a dedicated management interface but a new remote-access ACL accidentally admits guest-subnet SSH sessions. The change fails acceptance. What is the safest targeted restoration action?
- Move the AP back to its known-good group and restore last published site configuration if the reassignment fails.
- Restore the previous correct scope mapping and lease parameters, then renew a test client before wider rollout.
- Reapply the last controlled management ACL and known-good out-of-band path to preserve access while repairing isolation.
- Restore the previous valid RA and gateway configuration while protecting the segment from rogue router advertisements.
Explanation
Correct Answer
C:Reapply the last controlled management ACL and known-good out-of-band path to preserve access while repairing isolation. Data-plane connectivity and administrative reachability serve different trust boundaries; a dedicated management design restricts who can configure devices. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described management vlan access isolation situation.
Incorrect Answers
A:Move the AP back to its known-good group and restore last published site configuration if the reassignment fails. This instead concerns access point assignment to site and group. Central device enrollment and effective configuration group are separate steps; wrong scope can apply valid settings to the wrong site. It would not safely roll back the relevant failed change. The immediate problem concerns management vlan access isolation.
B: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 management vlan access isolation.
D: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.

The immediate problem concerns management vlan access isolation.
Question 53
A campus access switch has management reachable over a production VLAN where the approved design requires administrative traffic separation. Before implementing a remedy, what should the engineer check first?
- Review AP serial identity, selected site or group and effective inherited configuration before changing radios.
- Cross-check management interface or VRF assignments, reachability paths and source-access controls for administrative traffic.
- 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.
Explanation
Correct Answer
B:Cross-check management interface or VRF assignments, reachability paths and source-access controls for administrative traffic. Data-plane connectivity and administrative reachability serve different trust boundaries; a dedicated management design restricts who can configure devices. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described management vlan access isolation situation.
Incorrect Answers
A:Review AP serial identity, selected site or group and effective inherited configuration before changing radios. This instead concerns access point assignment to site and group.

Question 54
A campus access switch has management reachable over a production VLAN where the approved design requires administrative traffic separation. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Put management traffic in the approved dedicated interface or VRF and constrain permitted administrator sources.
- Map the AP to the correct device group and apply the intended approved WLAN configuration.
- Repair the host's DHCP scope or static configuration so address, prefix and gateway belong to the intended subnet.
- Activate appropriate authorized IPv6 RA behavior on the correct gateway interface with intended prefix and policy.

Question 55
A campus access switch has management reachable over a production VLAN where the approved design requires administrative traffic separation. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Review AP serial identity, selected site or group and effective inherited configuration before changing radios.
- Cross-check management interface or VRF assignments, reachability paths and source-access controls for administrative traffic.
- Repair the host's DHCP scope or static configuration so address, prefix and gateway belong to the intended subnet.
- Put management traffic in the approved dedicated interface or VRF and constrain permitted administrator sources.
Explanation
Correct Answers
B:Cross-check management interface or VRF assignments, reachability paths and source-access controls for administrative traffic. Data-plane connectivity and administrative reachability serve different trust boundaries; a dedicated management design restricts who can configure devices. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described management vlan access isolation situation.

Question 56
A campus access switch has management reachable over a production VLAN where the approved design requires administrative traffic separation. If the revised setting disrupts users, which controlled rollback would be most relevant?
- Transfer the AP back to its known-good group and restore last published site configuration if the reassignment fails.
- Reinstate the previous correct scope mapping and lease parameters, then renew a test client before wider rollout.
- Reapply the last controlled management ACL and known-good out-of-band path to preserve access while repairing isolation for the affected campus deployment.
- Reinstate the previous valid RA and gateway configuration while protecting the segment from rogue router advertisements.

Question 57
An AP is adopted into a management inventory but inherits a remote site's SSID settings because its assigned configuration group is wrong. Which investigation would best isolate the immediate network dependency?
- Compare host address and prefix, default gateway, switch VLAN and the gateway interface's network assignment.
- Inspect ICMPv6 router advertisements, RA flags, prefix information and default-route installation at the client.
- Inspect AP serial identity, selected site or group and effective inherited configuration before changing radios.
- Inspect LLDP neighbor identifiers, chassis and port IDs and the physical patching record for the affected link.
