Answers
C.
Configure additional SAN LIFs.
D.
Configure a higher queue depth on the target ports.
Answers
D.
Configure a higher queue depth on the target ports.
Suggested answer: B, C

Explanation:

When adding 40 more hosts to a two-node NetApp ONTAP cluster that is already hosting 64 SAN hosts, the following actions are necessary to avoid potential performance problems:

Configure additional FC target ports: Increasing the number of Fibre Channel (FC) target ports on the storage nodes will help distribute the I/O load more evenly, reducing the risk of bottlenecks.

Configure additional SAN LIFs: Adding more SAN Logical Interfaces (LIFs) will ensure that the increased number of hosts can connect efficiently, improving load balancing and path management.

These actions help maintain optimal performance and prevent congestion in the SAN environment.
