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.
Question 112 shows the exact same diagram twice, once with MSTP and one with DT. The diagram on the right in question 112 has both DT and VRRP, so answer C can’t be it. (Distributed trunking still uses VRRP as well)
Answer D is wrong, because the switches do not “act” as one device, the links to/from them are just aggregated.
Answer B looks wrong because I have never seen CLOS fabric and DT mentioned together. CLOS frabrics only have to do with what ports are being used
So, I think A is correct. Also, in question 112 DT replaces MSTP. STP means spanning tree, so it checks out.

Also, VRRP is routing, DT is link aggregation. They are completely unrelated. So, C cannot be it.
