A network designer is redesigning an enterprise campus network to ensure that Ethernet switches proactively attempt to reconnect after a fiber cut. In the design, they will have to address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber is disconnected in the fiber pair, leading to looping. Which feature could be implemented in the design to allow the Spanning Tree Protocol on the switches to be protected?
A. loop guard
B. UniDirectional Link Detection
C. UniDirectional Link Detection aggressive mode
D. root guard
Answer: C
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
