HP HPE7-A01 Practice Test 54
Question 530
A secure WLAN requires PMF but some client devices connect only when PMF is disabled on the SSID. 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.
- Correct the approved user-based role and supported dynamic segmentation or tunneled-node profile for the endpoint.
Explanation
Correct Answer
A:Apply the required PMF-capable security profile for modern clients and provide an approved isolated alternative for incompatible devices. Protected Management Frames help protect selected 802.11 management traffic and are mandatory for many modern WPA3 security profiles. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described protected management frames policy situation.
Incorrect Answers
B:Classify and contain the unauthorized device according to authorized wireless security and response policy. 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 implement the specifically required change. The immediate problem concerns protected management frames policy.
C:Replace broad permits with explicit least-privilege allowances and enforce a default deny for unauthorized paths. 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 would not implement the specifically required change. The immediate problem concerns protected management frames policy.
D:Correct the approved user-based role and supported dynamic segmentation or tunneled-node profile for the endpoint. This instead concerns dynamic segmentation user-based enforcement. Identity-driven segmentation should enforce consistent roles as endpoints move, rather than relying solely on static access-port VLAN placement. It would not implement the specifically required change. The immediate problem concerns protected management frames policy.
Question 531
A secure WLAN requires PMF but some client devices connect only when PMF is disabled on the SSID. Following a targeted change, which acceptance test would most directly demonstrate success?
- Verify the unauthorized transmitter no longer has a trusted wired path while legitimate campus APs stay available.
- Verify needed application flows succeed and negative probes to unrelated management or server subnets are denied.
- Verify policy follows the authorized user across access ports and the resulting path matches the intended enforcement point.
- Verify supported devices negotiate PMF and legacy clients are not silently admitted to the modern secured SSID.
Explanation
Correct Answer
D:Verify supported devices negotiate PMF and legacy clients are not silently admitted to the modern secured SSID. Protected Management Frames help protect selected 802.11 management traffic and are mandatory for many modern WPA3 security profiles. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described protected management frames policy situation.
Incorrect Answers
A:Verify the unauthorized transmitter no longer has a trusted wired path while legitimate campus APs stay available. 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 establish that this function actually works. The immediate problem concerns protected management frames policy.

Question 532
A secure WLAN requires PMF but some client devices connect only when PMF is disabled on the SSID. The change fails acceptance. What is the safest targeted restoration action?
- Reverse a mistaken containment action for an approved AP after confirming identity and restore normal service.
- Reinstate the last reviewed ACL order and remove the unsafe broad entry if policy validation fails.
- Restore the previously supported isolated legacy WLAN instead of disabling PMF for the protected enterprise SSID.
- Return the affected port to its last trusted segmentation configuration if an adjustment bypasses central enforcement.
Explanation
Correct Answer
C:Restore the previously supported isolated legacy WLAN instead of disabling PMF for the protected enterprise SSID. Protected Management Frames help protect selected 802.11 management traffic and are mandatory for many modern WPA3 security profiles. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described protected management frames policy situation.
Incorrect Answers
A:Reverse a mistaken containment action for an approved AP after confirming identity and restore normal service. 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 protected management frames policy.
B:Reinstate the last reviewed ACL order and remove the unsafe broad entry if policy validation fails. 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 would not safely roll back the relevant failed change.
