In the three-layer hierarchical network design model; what’s associated with the access layer? (Choose two)

A.
optimized transport structure

B.
high port density

C.
boundary definition

D.
data encryption

E.
local VLANs

F.
route summaries

Explanation:

The access layer is the outermost layer, and it is composed of the least sophisticated network equipment. The most important function of the access layer is high port density, since these devices connect the individual end users. The access layers are also where VLANs are implemented, since VLANs are assigned on a per-port basis.
