A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based
connectivity is not an option. Which design allows for a stable network when there is a risk of interference
from the manufacturing hardware in use on the factory floor?
A. Design the network to include UDLD to detect unidirectional links and take them out of service.
B. Design the network to include EtherChannel bundles to prevent a single-link failure from taking downa
switch interconnection point.
C. Design the network to include loop guard to prevent a loop in the switched network when a link has too
much interference.
D. Design the network to include BackboneFast on all devices to accelerate failure convergence times.
