HP HPE7-A01 Practice Test 59
Question 580
A network switch accepts Telnet from guest devices despite a policy requiring encrypted administrative sessions only. The change fails acceptance. What is the safest targeted restoration action?
- Restore a preapproved out-of-band encrypted management path rather than reopening unrestricted Telnet or weak SNMP access.
- Restore the last least-privilege user-role mapping if the new rule admits unexpected destinations.
- Restore the prior valid RADIUS trust configuration or reissue the authorized certificate while preserving EAP-TLS validation.
- Restore the previously supported isolated legacy WLAN instead of disabling PMF for the protected enterprise SSID.
Explanation
Correct Answer
A:Restore a preapproved out-of-band encrypted management path rather than reopening unrestricted Telnet or weak SNMP access. Administrative access should use authenticated encryption and controlled source permissions; functional cleartext protocols do not meet that objective. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described secure management protocols and telemetry situation.
Incorrect Answers
B:Restore the last least-privilege user-role mapping if the new rule admits unexpected destinations. This instead concerns role-based policy assignment. Authentication identifies a client; effective authorization is determined by the assigned role and its policy scope. It would not safely roll back the relevant failed change. The immediate problem concerns secure management protocols and telemetry.
C:Restore the prior valid RADIUS trust configuration or reissue the authorized certificate while preserving EAP-TLS validation. This instead concerns eap-tls client certificate trust. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. It would not safely roll back the relevant failed change. The immediate problem concerns secure management protocols and telemetry.
D:Restore the previously supported isolated legacy WLAN instead of disabling PMF for the protected enterprise SSID. This instead concerns protected management frames policy. Protected Management Frames help protect selected 802.11 management traffic and are mandatory for many modern WPA3 security profiles. It would not safely roll back the relevant failed change. The immediate problem concerns secure management protocols and telemetry.
Question 581
A monitoring system can poll switches only with SNMPv2c community strings after SNMPv3 credentials were rotated. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Review RADIUS returned attributes, effective user role and the matching policy decision on the access device.
- Review enabled management protocols, permitted source networks and the configured SSH or SNMPv3 security parameters.
- Reissue or correctly trust the approved client and issuing CA certificates under the existing EAP-TLS policy.
- Turn off unsafe cleartext management where required and configure authorized SSH or SNMPv3 with scoped access.
Explanation
Correct Answers
B:Review enabled management protocols, permitted source networks and the configured SSH or SNMPv3 security parameters. Administrative access should use authenticated encryption and controlled source permissions; functional cleartext protocols do not meet that objective. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described secure management protocols and telemetry situation.
D:Turn off unsafe cleartext management where required and configure authorized SSH or SNMPv3 with scoped access. Administrative access should use authenticated encryption and controlled source permissions; functional cleartext protocols do not meet that objective. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described secure management protocols and telemetry situation.
Incorrect Answers
A:Review RADIUS returned attributes, effective user role and the matching policy decision on the access device. This instead concerns role-based policy assignment. Authentication identifies a client; effective authorization is determined by the assigned role and its policy scope. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns secure management protocols and telemetry.
C:Reissue or correctly trust the approved client and issuing CA certificates under the existing EAP-TLS policy. This instead concerns eap-tls client certificate trust. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns secure management protocols and telemetry.
Question 582
A monitoring system can poll switches only with SNMPv2c community strings after SNMPv3 credentials were rotated. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Repair authorized identity-to-role mapping and role-specific policy enforcement without giving broader rights.
- Reissue or correctly trust the approved client and issuing CA certificates under the existing EAP-TLS policy.
- Turn off unsafe cleartext management where required and configure authorized SSH or SNMPv3 with scoped access.
- Enforce the required PMF-capable security profile for modern clients and provide an approved isolated alternative for incompatible devices.
Explanation
Correct Answer
C:Turn off unsafe cleartext management where required and configure authorized SSH or SNMPv3 with scoped access. Administrative access should use authenticated encryption and controlled source permissions; functional cleartext protocols do not meet that objective. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described secure management protocols and telemetry situation.
Incorrect Answers
A:Repair authorized identity-to-role mapping and role-specific policy enforcement without giving broader rights. This instead concerns role-based policy assignment. Authentication identifies a client; effective authorization is determined by the assigned role and its policy scope. It would not implement the specifically required change. The immediate problem concerns secure management protocols and telemetry.
B:Reissue or correctly trust the approved client and issuing CA certificates under the existing EAP-TLS policy. This instead concerns eap-tls client certificate trust. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. It would not implement the specifically required change. The immediate problem concerns secure management protocols and telemetry.
D:Enforce the required PMF-capable security profile for modern clients and provide an approved isolated alternative for incompatible devices. This instead concerns protected management frames policy.

Question 583
A monitoring system can poll switches only with SNMPv2c community strings after SNMPv3 credentials were rotated. A deployment job reports success. Which observed result would actually validate the affected service?
- Confirm the test account receives the intended role and can reach only applications explicitly permitted to it.
- Confirm encrypted authorized management works and plaintext or unauthorized management probes are rejected.
- Verify certificate validation succeeds and the permitted user role is assigned without insecure fallback.
- Confirm supported devices negotiate PMF and legacy clients are not silently admitted to the modern secured SSID.
Explanation
Correct Answer
B:Confirm encrypted authorized management works and plaintext or unauthorized management probes are rejected. Administrative access should use authenticated encryption and controlled source permissions; functional cleartext protocols do not meet that objective. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described secure management protocols and telemetry situation.
Incorrect Answers
A:Confirm the test account receives the intended role and can reach only applications explicitly permitted to it. This instead concerns role-based policy assignment. Authentication identifies a client; effective authorization is determined by the assigned role and its policy scope. It would not establish that this function actually works. The immediate problem concerns secure management protocols and telemetry.
C:Verify certificate validation succeeds and the permitted user role is assigned without insecure fallback. This instead concerns eap-tls client certificate trust. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. It would not establish that this function actually works. The immediate problem concerns secure management protocols and telemetry.

Question 584
A monitoring system can poll switches only with SNMPv2c community strings after SNMPv3 credentials were rotated. If the revised setting disrupts users, which controlled rollback would be most relevant?
- Reinstate a preapproved out-of-band encrypted management path rather than reopening unrestricted Telnet or weak SNMP access.
- Reinstate the last least-privilege user-role mapping if the new rule admits unexpected destinations.
- Reinstate the prior valid RADIUS trust configuration or reissue the authorized certificate while preserving EAP-TLS validation.
- Reinstate the previously supported isolated legacy WLAN instead of disabling PMF for the protected enterprise SSID.

Question 585
A staff laptop is linked to an access switchport but remains unauthorized because the configured RADIUS server is unreachable. Which investigation would best isolate the immediate network dependency?
- Inspect the 802.1X session state, RADIUS server reachability and EAP exchange logs from the switch.
- Inspect per-port authentication mode, voice VLAN identity and simultaneous phone and workstation session states.
- Inspect whether the endpoint supplies an 802.1X supplicant and whether MAC-based fallback is permitted by policy.
- Inspect RADIUS Access-Accept attributes and the switch's configured role or VLAN mapping behavior.
Explanation
Correct Answer
A:Inspect the 802.1X session state, RADIUS server reachability and EAP exchange logs from the switch. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described wired 802.1x and radius reachability situation.
Incorrect Answers
B:Inspect per-port authentication mode, voice VLAN identity and simultaneous phone and workstation session states. This instead concerns voice and data endpoints on an access port. Voice-plus-data access requires careful multi-device admission; one shared physical port does not imply one authorization context. It does not isolate the cause of the stated incident. The immediate problem concerns wired 802.1x and radius reachability.
C:Inspect whether the endpoint supplies an 802.1X supplicant and whether MAC-based fallback is permitted by policy. This instead concerns mac authentication bypass for non-supplicants. MAC authentication is an identity fallback for unsupported devices, not equivalent to certificate-backed EAP assurance. It does not isolate the cause of the stated incident. The immediate problem concerns wired 802.1x and radius reachability.
D:Inspect RADIUS Access-Accept attributes and the switch's configured role or VLAN mapping behavior. This instead concerns radius-returned vlan and role attributes. Successful RADIUS authentication is separate from authorization attributes; the switch must parse and apply the returned policy correctly. It does not isolate the cause of the stated incident. The immediate problem concerns wired 802.1x and radius reachability.
Question 586
A staff laptop is linked to an access switchport but remains unauthorized because the configured RADIUS server is unreachable. Which specific corrective design step best meets the stated campus requirement?
- Use a supported multi-endpoint authentication profile with separate authorized voice and data roles for the port.
- Configure restricted MAC authentication for the verified non-supplicant class while preserving normal 802.1X for capable endpoints.
- Align server-issued role or VLAN attributes with the supported switch authorization profile and valid local role names.
- Restore the approved RADIUS server address and routing path and apply an appropriate authorized 802.1X profile.
Explanation
Correct Answer
D:Restore the approved RADIUS server address and routing path and apply an appropriate authorized 802.1X profile. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described wired 802.1x and radius reachability situation.

It would not implement the specifically required change. The immediate problem concerns wired 802.1x and radius reachability.
C:Align server-issued role or VLAN attributes with the supported switch authorization profile and valid local role names. This instead concerns radius-returned vlan and role attributes. Successful RADIUS authentication is separate from authorization attributes; the switch must parse and apply the returned policy correctly. It would not implement the specifically required change. The immediate problem concerns wired 802.1x and radius reachability.
Question 587
A staff laptop is linked to an access switchport but remains unauthorized because the configured RADIUS server is unreachable. Following a targeted change, which acceptance test would most directly demonstrate success?
- Verify both approved devices receive their appropriate role or VLAN and an extra unauthorized device stays blocked.
- Verify the known device receives only its narrow role and an unregistered MAC does not acquire equivalent access.
- Verify a valid supplicant is authenticated and a negative-credential test remains denied.
- Verify the authenticated endpoint receives the intended effective role and access enforcement.
Explanation
Correct Answer
C:Verify a valid supplicant is authenticated and a negative-credential test remains denied. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described wired 802.1x and radius reachability situation.

Question 588
A staff laptop is linked to an access switchport but remains unauthorized because the configured RADIUS server is unreachable. The change fails acceptance. What is the safest targeted restoration action?
- Restore a known-good phone-only policy while correcting the workstation's separate authentication conditions.
- Return to the previously reachable RADIUS path or approved limited critical-auth policy without bypassing normal admission controls broadly.
- Restore the last limited device exception and disable an overbroad fallback rule if unauthorized devices match.
- Restore the last correct role dictionary and VLAN mappings if attribute changes grant excess access.
Explanation
Correct Answer
B:Return to the previously reachable RADIUS path or approved limited critical-auth policy without bypassing normal admission controls broadly. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described wired 802.1x and radius reachability situation.

Question 589
An office rollout enforces wired 802.1X, and all supplicants time out after the switch management VRF loses its route to the authentication server. Before implementing a remedy, what should the engineer check first?
- Review the 802.1X session state, RADIUS server reachability and EAP exchange logs from the switch.
- Review per-port authentication mode, voice VLAN identity and simultaneous phone and workstation session states.
- Review whether the endpoint supplies an 802.1X supplicant and whether MAC-based fallback is permitted by policy.
- Review RADIUS Access-Accept attributes and the switch's configured role or VLAN mapping behavior.
