What correctly describes one trend that is changing how network architects must design the data
center network infrastructure?

A.
Applications are drawing on more and more locally stored data, which causes customers to
favor blade servers and blade enclosures

B.
Applications are considering on single, highly available mainframes, driving the need for 10G
connections to the server edge

C.
Applications are increasingly virtualized, which requires architects to implement routing at the
access layer to segment each rack into its own VLAN

D.
Applications are scaling out across multiple servers, increasing communications between
servers distributed across the data center
