HP HPE7-A01 Practice Test 65
Question 640
A university revokes a student's access in its identity platform but the active wired session continues under the prior authorization. If the revised setting disrupts users, which controlled rollback would be most relevant?
- Reinstate the previously approved guest time window or revoke the account immediately if expiration enforcement fails.
- Return to the previously reachable RADIUS path or approved limited critical-auth policy without bypassing normal admission controls broadly.
- Reinstate a known-good phone-only policy while correcting the workstation's separate authentication conditions.
- Force a controlled reauthentication of the affected session and restore prior CoA settings while resolving delivery failures for the affected campus deployment.
Explanation
Correct Answer
D:Force a controlled reauthentication of the affected session and restore prior CoA settings while resolving delivery failures for the affected campus deployment. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described radius change of authorization situation.
Incorrect Answers
A:Reinstate the previously approved guest time window or revoke the account immediately if expiration enforcement fails. This instead concerns guest credentials and expiration enforcement. Guest identity issuance needs bounded time and scope; mere successful portal registration does not establish enduring access rights. It would not safely roll back the relevant failed change. The immediate problem concerns radius change of authorization.
B:Return to the previously reachable RADIUS path or approved limited critical-auth policy without bypassing normal admission controls broadly. This instead concerns wired 802.1x and radius reachability. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. It would not safely roll back the relevant failed change. The immediate problem concerns radius change of authorization. For the incident in this item: A university revokes a student's access in its identity platform but the active wired session continues under the prior authorization.
C:Reinstate a known-good phone-only policy while correcting the workstation's separate authentication conditions. 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 would not safely roll back the relevant failed change. The immediate problem concerns radius change of authorization.
Question 641
Temporary guest credentials remain valid after an event's scheduled end and permit unnecessary campus access. 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 the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing.
Explanation
Correct Answer
D:Inspect the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing. Guest identity issuance needs bounded time and scope; mere successful portal registration does not establish enduring access rights. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described guest credentials and expiration enforcement situation.
Incorrect Answers
A:Inspect the 802.1X session state, RADIUS server reachability and EAP exchange logs from the switch. This instead concerns wired 802.1x and radius reachability. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. It does not isolate the cause of the stated incident. The immediate problem concerns guest credentials and expiration enforcement.
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 guest credentials and expiration enforcement.
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 guest credentials and expiration enforcement.
Question 642
Temporary guest credentials remain valid after an event's scheduled end and permit unnecessary campus access. Which specific corrective design step best meets the stated campus requirement?
- Restore the approved RADIUS server address and routing path and apply an appropriate authorized 802.1X profile.
- Use a supported multi-endpoint authentication profile with separate authorized voice and data roles for the port.
- Apply the approved guest account validity window and least-privilege role based on the actual visit authorization.
- Configure restricted MAC authentication for the verified non-supplicant class while preserving normal 802.1X for capable endpoints.
Explanation
Correct Answer
C:Apply the approved guest account validity window and least-privilege role based on the actual visit authorization. Guest identity issuance needs bounded time and scope; mere successful portal registration does not establish enduring access rights. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described guest credentials and expiration enforcement situation.
Incorrect Answers
A:Restore the approved RADIUS server address and routing path and apply an appropriate authorized 802.1X profile. This instead concerns wired 802.1x and radius reachability. Wired 802.1X requires successful EAP communication through a RADIUS-backed authenticator; carrier state is not authorization. It would not implement the specifically required change. The immediate problem concerns guest credentials and expiration enforcement.
B:Use a supported multi-endpoint authentication profile with separate authorized voice and data roles for the port. 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 would not implement the specifically required change. The immediate problem concerns guest credentials and expiration enforcement.
D:Configure restricted MAC authentication for the verified non-supplicant class while preserving normal 802.1X for capable endpoints. 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 would not implement the specifically required change. The immediate problem concerns guest credentials and expiration enforcement.
Question 643
Temporary guest credentials remain valid after an event's scheduled end and permit unnecessary campus access. Following a targeted change, which acceptance test would most directly demonstrate success?
- Verify a valid supplicant is authenticated and a negative-credential test remains denied.
- Verify access succeeds only during the authorized interval and expires at the intended end.
- 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.
Explanation
Correct Answer
B:Verify access succeeds only during the authorized interval and expires at the intended end. Guest identity issuance needs bounded time and scope; mere successful portal registration does not establish enduring access rights. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described guest credentials and expiration enforcement situation.

Question 644
Temporary guest credentials remain valid after an event's scheduled end and permit unnecessary campus access. The change fails acceptance. What is the safest targeted restoration action?
- Restore the previously approved guest time window or revoke the account immediately if expiration enforcement fails.
- Return to the previously reachable RADIUS path or approved limited critical-auth policy without bypassing normal admission controls broadly.
- Restore a known-good phone-only policy while correcting the workstation's separate authentication conditions.
- Restore the last limited device exception and disable an overbroad fallback rule if unauthorized devices match.

Question 645
A contractor receives a guest account that expires before the agreed maintenance window, causing an unexpected lockout. 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 the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing.
Explanation
Correct Answer
D:Review the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing. Guest identity issuance needs bounded time and scope; mere successful portal registration does not establish enduring access rights.

Question 646
A contractor receives a guest account that expires before the agreed maintenance window, causing an unexpected lockout. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Reinstate the approved RADIUS server address and routing path and apply an appropriate authorized 802.1X profile.
- Choose a supported multi-endpoint authentication profile with separate authorized voice and data roles for the port.
- Enforce the approved guest account validity window and least-privilege role based on the actual visit authorization.
- Set up restricted MAC authentication for the verified non-supplicant class while preserving normal 802.1X for capable endpoints.
Explanation

Question 649
A security analyst cannot determine whether a campus switch forwards DHCP offers because a span capture on the wrong interface is empty. Which investigation would best isolate the immediate network dependency?
- Inspect the mirror session source, selected direction and destination interface capacity for the affected flow.
- Inspect the installed NAE script, monitored resource, condition and action history for the target metric.
- Inspect UXI sensor connectivity and the configured internal, external and authentication test definitions.
- Inspect per-client association, authentication, roaming and disconnect events correlated to the user's timeline.
Explanation
Correct Answer
A:Inspect the mirror session source, selected direction and destination interface capacity for the affected flow. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described port mirroring and pcap capture situation.
Incorrect Answers
B:Inspect the installed NAE script, monitored resource, condition and action history for the target metric. This instead concerns network analytics engine monitor rules. NAE scripts link monitors, rules, conditions and actions; the existence of a script does not prove its trigger or collection path works. It does not isolate the cause of the stated incident. The immediate problem concerns port mirroring and pcap capture.
C:Inspect UXI sensor connectivity and the configured internal, external and authentication test definitions. This instead concerns uxi sensor internal and external testing. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. It does not isolate the cause of the stated incident. The immediate problem concerns port mirroring and pcap capture.
D:Inspect per-client association, authentication, roaming and disconnect events correlated to the user's timeline. This instead concerns aruba central client health and event timeline. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase. It does not isolate the cause of the stated incident. The immediate problem concerns port mirroring and pcap capture.
Question 650
A security analyst cannot determine whether a campus switch forwards DHCP offers because a span capture on the wrong interface is empty. Which specific corrective design step best meets the stated campus requirement?
- Deploy a supported NAE monitor and rule with the right threshold and bounded diagnostic action for that AOS-CX model.
- Configure approved UXI synthetic tests for the affected wireless or wired access journey and application target.
- Enable the appropriate supported client insight and alerting scope for the target site without expanding unrelated log collection.
- Configure a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription.
