Designing Cisco Data Center Infrastructure (DCID) — Question 54

An engineer is implementing a storage area network where an NPV is used. The engineer notices that the servers in a storage farm are experiencing heavy traffic contention. The engineer needs to migrate traffic from heavily loaded server interfaces to interfaces with less load. When the new links are deployed, the existing traffic is not rebalanced as expected. Which feature must be used to meet these requirements?

Answer options

Correct answer: A

Explanation

NPIV (N_Port ID Virtualization) allows multiple N_ports to share a single physical port, which helps in rebalancing traffic among server interfaces. The other options, such as multiple VSAN support and DPVM, do not specifically address the issue of traffic contention and load balancing like NPIV does. Disruptive load balancing, while it may seem relevant, typically involves more interruptions and is not as efficient in dynamic rebalancing as NPIV.
