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 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 down a 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.

Answer: A
