Exhibit: Your customer plans to deploy the edge WAE appliances in an off-path, two-arm
configuration. The WAE appliances are connected to Cisco Catalyst 6500 Series Switches
and use WCCPv2 for traffic interception. The customer wants to minimize the latency added
by interception. The customer also wants to know if Layer 2 redirection, rather than GRE
tunnels, will improve performance.What should you tell your customer?

A.
Layer 2 redirection can be used in the customer configurations

B.
GRE tunnels provide better performance than Layer 2 redirection

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

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