HP HPE7-A01 Practice Test 64
Question 630
A certificate-replacement rollout leaves devices presenting an untrusted expired machine certificate to RADIUS. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Set up the required EAP-TLS supplicant method and enroll valid trusted certificates under the existing identity policy.
- Activate and permit authorized RADIUS Change of Authorization or session reauthentication for role changes.
- Enforce the approved guest account validity window and least-privilege role based on the actual visit authorization.
- Reinstate the approved RADIUS server address and routing path and apply an appropriate authorized 802.1X profile.
Explanation
Correct Answer
A:Set up the required EAP-TLS supplicant method and enroll valid trusted certificates under the existing identity policy. EAP methods have different credential prerequisites, and certificate expiration or method mismatch cannot be fixed by changing RF channel power. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described certificate lifecycle and eap method mismatch situation.
Incorrect Answers
B:Activate and permit authorized RADIUS Change of Authorization or session reauthentication for role changes. This instead concerns radius change of authorization. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect. It would not implement the specifically required change. The immediate problem concerns certificate lifecycle and eap method mismatch.
C:Enforce the approved guest account validity window and least-privilege role based on the actual visit authorization. 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 implement the specifically required change. The immediate problem concerns certificate lifecycle and eap method mismatch.
D:Reinstate 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 certificate lifecycle and eap method mismatch.
Question 631
A certificate-replacement rollout leaves devices presenting an untrusted expired machine certificate to RADIUS. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Review the live session identifier, RADIUS CoA delivery and switch support for reauthorization triggers.
- Review negotiated EAP method, supplicant profile, certificate validity and RADIUS failure reason.
- Enforce the approved guest account validity window and least-privilege role based on the actual visit authorization.
- Set up the required EAP-TLS supplicant method and enroll valid trusted certificates under the existing identity policy.
Explanation
Correct Answers
B:Review negotiated EAP method, supplicant profile, certificate validity and RADIUS failure reason. EAP methods have different credential prerequisites, and certificate expiration or method mismatch cannot be fixed by changing RF channel power. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described certificate lifecycle and eap method mismatch situation.
D:Set up the required EAP-TLS supplicant method and enroll valid trusted certificates under the existing identity policy. EAP methods have different credential prerequisites, and certificate expiration or method mismatch cannot be fixed by changing RF channel power. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described certificate lifecycle and eap method mismatch situation.
Incorrect Answers
A:Review the live session identifier, RADIUS CoA delivery and switch support for reauthorization triggers. This instead concerns radius change of authorization. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns certificate lifecycle and eap method mismatch.
C:Enforce the approved guest account validity window and least-privilege role based on the actual visit authorization. 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 is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns certificate lifecycle and eap method mismatch.
Question 632
A certificate-replacement rollout leaves devices presenting an untrusted expired machine certificate to RADIUS. If the revised setting disrupts users, which controlled rollback would be most relevant?
- Force a controlled reauthentication of the affected session and restore prior CoA settings while resolving delivery failures for the affected campus deployment.
- Reinstate the previously approved guest time window or revoke the account immediately if expiration enforcement fails.
- Reinstate a valid prior certificate or properly managed temporary device policy without silently accepting the weaker EAP method.
- Return to the previously reachable RADIUS path or approved limited critical-auth policy without bypassing normal admission controls broadly.
Explanation
Correct Answer
C:Reinstate a valid prior certificate or properly managed temporary device policy without silently accepting the weaker EAP method. EAP methods have different credential prerequisites, and certificate expiration or method mismatch cannot be fixed by changing RF channel power. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described certificate lifecycle and eap method mismatch situation.
Incorrect Answers
A:Force a controlled reauthentication of the affected session and restore prior CoA settings while resolving delivery failures for the affected campus deployment. This instead concerns radius change of authorization. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect. It would not safely roll back the relevant failed change. The immediate problem concerns certificate lifecycle and eap method mismatch.
B: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 certificate lifecycle and eap method mismatch.
D: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 certificate lifecycle and eap method mismatch. For the incident in this item: A certificate-replacement rollout leaves devices presenting an untrusted expired machine certificate to RADIUS.
Question 633
A quarantined user is remediated by endpoint security but their switch session retains the old restrictive role until reconnect. Which investigation would best isolate the immediate network dependency?
- Inspect the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing.
- Inspect the 802.1X session state, RADIUS server reachability and EAP exchange logs from the switch.
- Inspect the live session identifier, RADIUS CoA delivery and switch support for reauthorization triggers.
- Inspect per-port authentication mode, voice VLAN identity and simultaneous phone and workstation session states.
Explanation
Correct Answer
C:Inspect the live session identifier, RADIUS CoA delivery and switch support for reauthorization triggers. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described radius change of authorization situation.
Incorrect Answers
A:Inspect the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing. 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 does not isolate the cause of the stated incident. The immediate problem concerns radius change of authorization.
B: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 radius change of authorization.
D: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 radius change of authorization.
Question 634
A quarantined user is remediated by endpoint security but their switch session retains the old restrictive role until reconnect. Which specific corrective design step best meets the stated campus requirement?
- Apply the approved guest account validity window and least-privilege role based on the actual visit authorization.
- Enable and permit authorized RADIUS Change of Authorization or session reauthentication for role changes.
- 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.
Explanation
Correct Answer
B:Enable and permit authorized RADIUS Change of Authorization or session reauthentication for role changes. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect.

Question 635
A quarantined user is remediated by endpoint security but their switch session retains the old restrictive role until reconnect. Following a targeted change, which acceptance test would most directly demonstrate success?
- Verify the active endpoint role changes without an unrelated link outage after the identity decision is updated.
- Verify access succeeds only during the authorized interval and expires at the intended end.
- Verify a valid supplicant is authenticated and a negative-credential test remains denied.
- Verify both approved devices receive their appropriate role or VLAN and an extra unauthorized device stays blocked.
Explanation
Correct Answer
A:Verify the active endpoint role changes without an unrelated link outage after the identity decision is updated. A new authorization decision must reach the active network session; RADIUS CoA can trigger change without waiting for a physical reconnect. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described radius change of authorization situation.
Incorrect Answers
B:Verify access succeeds only during the authorized interval and expires at the intended end. 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 establish that this function actually works. The immediate problem concerns radius change of authorization.
C:Verify a valid supplicant is authenticated and a negative-credential test remains denied. 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 establish that this function actually works.

Question 636
A quarantined user is remediated by endpoint security but their switch session retains the old restrictive role until reconnect. 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.
- Force a controlled reauthentication of the affected session and restore prior CoA settings while resolving delivery failures.

Question 637
A university revokes a student's access in its identity platform but the active wired session continues under the prior authorization. Before implementing a remedy, what should the engineer check first?
- Review the issued guest role, start and expiry timestamps and captive portal or RADIUS policy processing.
- Review the 802.1X session state, RADIUS server reachability and EAP exchange logs from the switch.
- Review the live session identifier, RADIUS CoA delivery and switch support for reauthorization triggers.
