AFF A250 systems use aconverged networking design, where the same physical ports are used for bothcluster interconnect traffic and HA interconnect traffic. This differs from older platforms that used dedicated HA interconnect ports.

The NetApp CN1610 switches only support10GbE, which is insufficient for AFF A250 systems. AFF A250 platforms require25GbE-capable cluster switchesto support both cluster and HA interconnect traffic.

Because the cluster ports are operational, the nodes can join the cluster. However, the HA interconnect traffic cannot be established due to insufficient switch capability, which explains why the NVRAM log cannot synchronize and the HA partner is unreachable.

Therefore:

The AFF A250requires switches with 25GbE port support

The AFF A250uses the same ports for cluster and HA interconnect

Statements involving 40GbE or separate HA ports are incorrect.

The correct answers areC and D.

From a hardware installation perspective, NetApp SAS shelves are designed to function witha minimum of one installed disk. While performance, redundancy, and aggregate creation require additional disks, the physical shelf itself does not mandate a minimum disk count beyond one for detection and operation.

This flexibility allows administrators to stage hardware installations or expand capacity incrementally. However, ONTAP best practices strongly recommend populating shelves in ways that support RAID protection and performance requirements.

Therefore, the minimum number of disks required in a SAS shelf isone, making optionBcorrect.
