Designing Cisco Data Center Infrastructure (DCID) — Question 47
A network engineer is using a Cisco UCS environment connected to a Fibre Channel storage array. The Cisco UCS environment must be connected to an existing SAN network, and several Cisco MDS 9000 Series Switches must be added to increase storage density. The solution must not exhaust the SAN network from the list of available domain IDs after connecting. Also, most of the SAN traffic must be mapped from the Cisco UCS blades to a specific group of the fabric interconnect ports. Which two features must be deployed to meet these requirements? (Choose two.)
Answer options
- A. dynamic port pinning
- B. end host mode
- C. static PIN grouping
- D. N-Port ID virtualization
- E. priority flow control
Correct answer: E
Explanation
The correct answer is E, as priority flow control helps manage SAN traffic efficiently, ensuring that it does not congest the network. The other options, while useful in certain contexts, do not specifically address the requirement for managing traffic flow and avoiding domain ID exhaustion as effectively as priority flow control does.
