Discuss HP HPE7-A07 Exam Topic 9 Question 53

A campus topology uses VSX with a collapsed core topology. The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link. You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.

What is a valid configuration?

AOption A

BOption B

COption C

DOption D

Suggested Answer: A

The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC-LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.

I feel like option B might be the right choice, but I can't recall the exact details we discussed about the SFP+ transceivers and their configurations.

I'm a bit uncertain about the differences between the options. Did we cover how to identify the correct CLI outputs for these configurations?

Luann 3 months ago

I think I saw a similar question in our last mock exam, and I want to say that option C had the right parameters for link aggregation.

I remember we practiced link aggregation configurations, but I'm not entirely sure which option shows the correct settings for the mobility gateways.
