HP HPE7-A07 Exam With Confidence Using Practice Dumps

In BGP, the route marked with a ">" symbol is the best route that is chosen based on BGP attributes in the following order: highest weight (Cisco-specific), highest local preference, originated by BGP running on the local router, shortest AS path, lowest origin type, lowest MED, eBGP over iBGP, closest IGP neighbor, and lowest BGP router ID. Based on the table provided, Option E would be marked with a ">" symbol as it has the highest local preference of 100 which is a decisive factor in the BGP best path selection process.

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.

In Aruba AOS-CX, OSPF neighbors that reach EXSTART/EXCHANGE but fail to advance typically indicate a database description (DD) negotiation issue, most commonly caused by an MTU mismatch on the link. The OSPF header carries the interface MTU; if the values do not match, the peer rejects DD packets and the adjacency remains stuck at EXSTART (often shown as EXSTART/DR or EXSTART/BDR).

Aruba’s OSPF guidance states:

“If neighbors remain in EXSTART/EXCHANGE, verify that the Layer-3 MTU matches on both ends of the adjacency. An MTU mismatch causes DD packets to be rejected and prevents the adjacency from reaching FULL.”

Recommended corrective action is to align or remove custom L3 MTU settings on the participating interfaces (or use the mtu-ignore feature where appropriate).

In this scenario, removing the custom Layer-3 MTU configuration so both sides use the same default MTU allows DD packet negotiation to succeed and the adjacency to progress to FULL.
