Which load balancing method should be used to accomplish this goal?

An environment consists of a Cisco MDS 9000 Series Switch that uses port channels. An engineer must ensure that frames between the source and the destination follow the same links for a specific flow. Subsequent flows are allowed to use a different link.

Which load balancing method should be used to accomplish this goal?
A . src-id/dst-id
B . src-dst-oui
C . src-dst-port
D . src-id/dst-id/oxid

Answer: C

Explanation:

The src-dst-port load balancing method ensures that frames in the same flow (identified by the source and destination ports) follow the same links in a port channel. This method is effective in environments with Cisco MDS 9000 Series Switches because it maintains the order of frame delivery within a flow, which is crucial for storage traffic. Subsequent flows can use different links, allowing for efficient utilization of the port channel bandwidth.
