Which of these statements is true concerning the data center access layer design?

A.
The access layer in the data center is typically built at Layer 3, which allows for better sharing
of services across multiple servers.

B.
With Layer 2 access, the default gateway for the servers can be configured at the access or
aggregation layer.

C.
A dual-homing NIC requires a VLAN or trunk between the two access switches to support the
dual IP addresses on the two server links to two separate switches.

D.
The access layer is normally not required, as dual homing is standard from the servers to the
aggregation layer.

Explanation:

With Layer 2 / 3, capabilities in-built access layer switches can have data & voice VLANs with
interfaces; this is helpful in improving routing convergence.
