Which architecture provides the highest degree of connectivity in the event of the pictured failure?

The diagrams show two possible physical network architectures.
Each architecture provides a means in dealing with the pictured failure. Which architecture
provides the highest degree of connectivity in the event of the pictured failure?

A.
Diagram A’s architecture will provide the highest percentage of connectivity in times of
failure.

B.
Neither design is properly architected to work around the displayed failure.

C.
Both designs will provide the same percentage of connectivity in times of failure.

D.
Diagram B’s architecture will provide the highest percentage of connectivity in times of
failure.
