You have added two new AFF A250 nodes to an existing 4-node cluster with NetApp CN1610 cluster network switches. Although the nodes can join the cluster, the storage failover show command output shows that the NVRAM log is not synchronized, and it cannot reach the partner over an HA interconnect.
In this scenario, which two statements are true? (Choose two.)
The AFF A250 uses the same port for both the cluster network and the HA interconnect, which eliminates the possibility of it using different ports (so B is incorrect). Additionally, the AFF A250 does not require 25GbE port support but rather 40GbE port support to ensure the proper functionality of both cluster and HA interconnect, making A the correct option. Therefore, the true statements in this scenario are that the AFF A250 requires switches with 40GbE port support and uses the same port for the cluster and the HA interconnect.

Agree with CD
I agree too CD
This platform and configuration is not supported with CN1610 switches The AFF A250, AFF C250 and FAS500f model uses the same port (e0c, e0d) for both the cluster network connection and the HA interconnect between the HA pair.
