HP HPE7-A08 Exam Dumps - Actual Questions Answers

To capture packets on an HPE Aruba CX switch and view the output remotely in real-time, the best practice is to use a mirror session that forwards traffic to a remote device running a packet analyzer such as Wireshark. ERSPAN (Encapsulated Remote Switched Port Analyzer) allows the mirror traffic to be encapsulated in GRE and sent over an IP network to a remote monitoring station. This method ensures full packet capture with no local resource constraints and provides full visibility to the analyst.

Option B (using tcpdump on the switch) only provides summarized or limited capture locally.

Option C (mirroring to another switch port) only allows local monitoring and does not provide remote real-time viewing.

Option D (mirror to CPU and then use tshark) is less efficient and may be resource-intensive on the switch.

Therefore, configuring ERSPAN to a remote Wireshark host is the recommended and best way.

When adding a switch with an existing configuration into a group in Aruba Central, the group requires devices to have factory default configurations to allow Central to apply the group config correctly.

If the switch has an existing configuration, synchronization and auto-commit may fail because of configuration conflicts.

Option A: Pending authorization is unrelated to config synchronization.

Option C: Auto-commit can be disabled but does not block syncing existing config.

Option D: VSX support limitations are irrelevant here.

Therefore, the likely cause is that only switches with factory default config can be added to a group with existing config.

When line card LEDs do not light up, and the cards are newly installed, the best troubleshooting methodology is Divide and conquer by swapping the line cards. This method isolates the problem by testing hardware in different slots or known working units.

Spot the difference involves comparing configurations, which does not directly isolate hardware failure.

Follow the path is more suited for connectivity issues.

Replace configuration relates to software or config problems.

Hardware issues are best isolated by physically swapping components.
