Refer to the exhibit.

A network architect has designed the topology in the exhibit. The Gigabit links between layer and
the core uses OM3 grade multi-mode fiber between 100m and 150m long.
The solution is for an enterprise customer whose employees use mostly HTTP-based application
and have medium utilization needs.
What should the network architect do to resolve a potential issue?

A.
Replace the modular switches at the access layer with switches that support stacked meshing.

B.
Add more bandwidth between each pair of distribution layer switches and the core switches.

C.
Add more links between each modular switch at the access layer and its distribution layer
switch.

D.
Remove the distribution layer since it is not needed on this environment.
