Two switches connected with a single link

[DoHuuBa]

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?

1. Open Shortest Path First (OSPF)
2. Priority-based Flow Control (PFC)
3. RDMA over Converged Ethernet (RoCE)
4. Multi Active Discriminator (MAD)

Do you need help with this question or it is a test for us? (-:

Anyhow, I bet on 'PFC', because the issue is with traffic prioritization on transit devices and PFC is the only technology from this list that is relevant.
