Refer to the exhibit. Your customer plans to deploy its edge WAE appliances in an off-path, two-arm configuration. The WAE appliances are connected to Catalyst 6500 switches and use WCCPv2 for traffic interception. The customer wants to use Layer 2 redirection, rather than GRE tunnels, to minimize the latency added by interception.

What should you say when you are asked if this is possible?

A.
Layer 2 redirection can be used only in in-path configurations.

B.
Layer 2 redirection can be used only in one-arm configurations.

C.
Layer 2 redirection can be used in the customer’s configuration.

D.
GRE tunnels provide better performance than Layer 2 redirection.
