Refer to the exhibit.

The switches in this network are HP ProVision switches.
The network architect plans to set up Core 1 and Core 2 as distributed trunking (DT) switches.
What is an advantage of this design?

A.
The core switches connect to each access layer switch over one link aggregation, which
provides better failover than spanning tree

B.
The core switches become a single CLOS fabric, which lets them to provide faster and more
reliable routing for a virtualized environment.

C.
The core switches no longer need to implement VRRP. Instead DT provides faster and more
reliable redundancy for default gateway services.

D.
The core switches act as a single logical device, which simplifies management of the
networking devices.
