FC0-U71 Infrastructure — 30 Questions

Question 1

A network administrator is designing a new office network and wants to use a topology that provides redundancy so that if one cable fails, communication can still occur via alternate paths. Which TWO topologies offer this redundancy? (Choose TWO.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Hybrid topology. Mesh topology connects every device to every other device, providing multiple paths so that a single cable failure does not disrupt communication. Hybrid topology combines multiple topologies and can include redundant paths (e.g., a partial mesh component) allowing alternate routes. In contrast, star topology lacks alternate paths for the affected device, ring topology breaks entirely with a single cable fault, and bus topology also fails when the main cable is broken.

Answer

Ring topology

Answer

Star topology

Answer

Bus topology

Question 2

A technician is upgrading a desktop computer's memory. Which component would the technician most likely replace to improve system performance using dual-channel architecture?
