HP HPE7-A07 Exam With Confidence Using Practice Dumps

To address connectivity issues when students are working outdoors, increasing the transmission (TX) power range for the 5GHz radios can help improve signal strength and coverage. The setting shown indicates a conservative approach to power settings, which might not provide sufficient coverage for outdoor areas. By increasing the power range, you can extend the wireless signal reach, which aligns with best practices for outdoor wireless coverage.

ClearPass Request Details shows:Error Code: 9002 — Error Category: RADIUS protocol — Error Message: Request timed out and the alert “Client did not complete EAP transaction.”Exact extract (ClearPass Troubleshooting):“When ClearPass does not receive the next EAP message (for example, because RADIUS packets are dropped or fragmented on the network), Policy Manager logs Error Code 9002 (Request timed out) and the alert ‘Client did not complete EAP transaction’. This indicates a transport problem between the NAS/AP and ClearPass rather than a credential or certificate error.”

AP show ap-debug auth-trace-buf shows:... eap-req / eap-resp ... rad-req ... dot1x-timeout ... server timeoutExact extract (Aruba WLAN Debugging Guide):“dot1x-timeout server timeout in the AP trace indicates the AP did not receive a RADIUS response from the authentication server. Investigate path MTU/fragmentation or firewall filtering between the AP/gateway and the RADIUS server.”

Packet capture of the Access-Request includes AVP: Framed-MTU = 1100 and large EAP-TLS payloads (certificate exchange).Exact extract (Aruba 802.1X/EAP Design Guidance):“EAP-TLS exchanges can produce large RADIUS packets due to certificate payloads. If the path MTU is smaller than the EAP-TLS message size, IP fragmentation occurs and intermediate devices may drop fragments, causing RADIUS timeouts. Use the Framed-MTU attribute (for example, 1100) and ensure the network path supports the selected MTU to avoid EAP-TLS failures.”

Putting this together: the AP is sending EAP-TLS to ClearPass, ClearPass reports a timeout, and the AP reports server timeout—a classic symptom of RADIUS/EAP-TLS fragmentation due to an MTU that is too small somewhere in the path. The presence of Framed-MTU 1100 in the Access-Request further highlights MTU handling; if any hop still enforces a lower MTU or blocks fragments, the exchange stalls and ClearPass times out.

Therefore, the failure is caused by insufficient MTU (fragmentation/drop) between the AP and ClearPass, matching option B.

In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.
