Authentic HP Certification Exam HPE7-A08 Questions Answers

The troubleshooting methodology exemplified by comparing outputs or configurations to find discrepancies is called Spot the difference. It involves checking variations between working and non-working states or devices.

Follow the path: tracing packet flow step-by-step.

Top-down/Bottom-up: analyzing layers systematically.

Replace configuration: swapping configurations to isolate issues.

Here, comparing command outputs aligns with spot-the-difference.

When deploying a new Aruba CX 8325 switch to provide gateway and routing services, the L3-apg profile (Layer 3 Aggregation Profile) should be selected instead of the factory default. This profile is designed for switches acting as aggregation or core routers, enabling Layer 3 routing capabilities and optimized configurations for such roles.

The Spine profile (factory default) is optimized for leaf/spine architectures, but may not be ideal for aggregation gateways.

Leaf and L3-core profiles are targeted for different roles.

Using the L3-apg profile helps to ensure the switch is correctly optimized for Layer 3 gateway functions.

When a recent routing change causes an outage affecting all users, the recommended immediate action is to restore the last-known working configuration to quickly return the network to a stable state. This is critical to minimize downtime and impact.

Asking customers to send logs or explaining the issue takes time and delays remediation.

Collecting show tech and opening TAC cases can be done after restoring service.

Hence, the quickest way to mitigate the impact is to restore the last known good configuration.
