HPE Virtual Connect Solutions v4 — Question 85

An administrator has two switches connected with a single link. The administrator observes that, during hours of peak activity, the storage traffic tends to consume the link. The link is shared with other types of traffic that is time sensitive.
What technology can the administrator use to help alleviate the situation while they are working towards a long-term solution?

Answer options

• A. Priority-based Flow Control (PFC)
• B. Multi Active Discriminator (MAD)
• C. RDMA over Converged Ethernet (RoCE)
• D. Open Shortest Path First (OSPF)

Correct answer: A

Explanation

Priority-based Flow Control (PFC) is the correct choice as it allows for the prioritization of specific traffic types, ensuring that time-sensitive data can flow without significant interruption from storage traffic. The other options, such as MAD, RoCE, and OSPF, do not provide mechanisms for traffic prioritization in the same way and are not designed to manage congestion on a shared link.
