Designing Cisco Data Center Infrastructure (DCID) — Question 61

A network consultant evaluates the Cisco UCS Fabric Interconnect SAN configuration, which must meet these requirements:

• All traffic must pass over the upstream device for switching and domain IDs must be preserved in the fabric.
• Each server should be pinned to one designated upstream interface and for the traffic to pass through the pinned port.

Which Fabric Interconnect SAN operational mode meets these requirements?

Answer options

• A. end host
• B. switch
• C. NPIV
• D. Fibre Channel

Correct answer: A

Explanation

The correct answer is A, end host mode, as it allows for all traffic to flow through the upstream device while preserving domain IDs. In contrast, switch mode (B) and Fibre Channel (D) do not enforce the same pinning requirement for upstream interfaces, and NPIV (C) is more about virtualizing resources rather than the traffic flow and pinning described in the requirements.
