Refer to the exhibit.
The exhibit shows the current plan for a wired network upgrade.
As much as possible, the customer wants to flatten the architecture and avoid recabling. However, each Building 2 switch must also maintain connectivity to the core if one link fails. What should the architect propose to meet the customer requirements?
A. Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections.
B. Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers.
C. Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.
D. Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.
