HP HPE7-A01 Practice Test 53
Question 520
A research employee logs in correctly over Wi-Fi yet inherits the general staff role rather than the restricted lab access profile. If the revised setting disrupts users, which controlled rollback would be most relevant?
- 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.
- Reverse a mistaken containment action for an approved AP after confirming identity and restore normal service for the affected campus deployment.
Explanation
Correct Answer
A:Reinstate the last least-privilege user-role mapping if the new rule admits unexpected destinations. Authentication identifies a client; effective authorization is determined by the assigned role and its policy scope. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described role-based policy assignment situation.
Incorrect Answers
B:Reinstate 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 role-based policy assignment.
C:Reinstate 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 role-based policy assignment.
D:Reverse a mistaken containment action for an approved AP after confirming identity and restore normal service for the affected campus deployment. This instead concerns rogue ap detection and classification. A shared SSID name does not prove device authorization; rogue classification requires comparing RF observations with trusted infrastructure evidence. It would not safely roll back the relevant failed change. The immediate problem concerns role-based policy assignment.
Question 521
A managed laptop sends an EAP-TLS client certificate but a campus RADIUS server rejects it after its CA trust list was changed. Which investigation would best isolate the immediate network dependency?
- Inspect certificate chain, subject identity, validity dates and RADIUS or EAP rejection events.
- Inspect AP PMF requirement, client capability information and association failure reason.
- Inspect rogue detection records, BSSID details, wired connectivity evidence and approved AP inventory.
- Inspect ordered ACL or role policy matches for representative source, destination and service tuples.
Explanation
Correct Answer
A:Inspect certificate chain, subject identity, validity dates and RADIUS or EAP rejection events. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described eap-tls client certificate trust situation.

It does not isolate the cause of the stated incident. The immediate problem concerns eap-tls client certificate trust.
D:Inspect ordered ACL or role policy matches for representative source, destination and service tuples. This instead concerns acl default deny and segmentation. Ordered access policies match traffic by their conditions; one broad early permit can defeat later restrictive entries. It does not isolate the cause of the stated incident. The immediate problem concerns eap-tls client certificate trust.
Question 522
A managed laptop sends an EAP-TLS client certificate but a campus RADIUS server rejects it after its CA trust list was changed. Which specific corrective design step best meets the stated campus requirement?
- Apply the required PMF-capable security profile for modern clients and provide an approved isolated alternative for incompatible devices.
- Classify and contain the unauthorized device according to authorized wireless security and response policy.
- Replace broad permits with explicit least-privilege allowances and enforce a default deny for unauthorized paths.
- Renew or correctly trust the approved client and issuing CA certificates under the existing EAP-TLS policy.
Explanation
Correct Answer
D:Renew or correctly trust the approved client and issuing CA certificates under the existing EAP-TLS policy. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described eap-tls client certificate trust situation.

Question 523
A managed laptop sends an EAP-TLS client certificate but a campus RADIUS server rejects it after its CA trust list was changed. Following a targeted change, which acceptance test would most directly demonstrate success?
- Verify supported devices negotiate PMF and legacy clients are not silently admitted to the modern secured SSID.
- Verify the unauthorized transmitter no longer has a trusted wired path while legitimate campus APs stay available.
- Confirm certificate validation succeeds and the permitted user role is assigned without insecure fallback.
- Verify needed application flows succeed and negative probes to unrelated management or server subnets are denied.
Explanation
Correct Answer
C:Confirm certificate validation succeeds and the permitted user role is assigned without insecure fallback. EAP-TLS security relies on a valid certificate chain and identity policy; strong RF and successful association cannot bypass certificate checks. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described eap-tls client certificate trust situation.
