A、Server-to-server traffic always remains in the core layer. B、The recommended practice is for the core infrastructure to be in Layer 3. C、The boundary between Layer 2 and Layer 3 should be implemented in the aggregation layer. D、The Cisco Express Forwarding hashing algorithm is the default, based on the IP address and Layer 4 port. E、Core layer should run BGP along with an IGP becauseiBGP has a lower administrative distance than any IGP.
