Correct Answer: CD
To properly tunnel client traffic between the ArubaOS-CX switch and the Aruba Gateway, it is important to not block IP Protocol 47 (GRE) on the datapath as GRE tunnels use this protocol. Additionally, GRE-encapsulated frames may exceed the standard MTU size, so adjusting the default MTU on the data-path between the switch and gateway is necessary to ensure compatibility and prevent fragmentation of these frames.
