In which of the following types of network would STP be used?
The correct answer is B. An Ethernet network with redundant paths. Spanning Tree Protocol (STP) is used specifically in Ethernet Layer 2 networks to prevent loops caused by redundant paths. STP detects loops and blocks one or more redundant paths to ensure there is a loop-free topology in a bridged network. STP dynamically recalculates the…

Explanation
Spanning Tree Protocol (STP) is used specifically in Ethernet Layer 2 networks to prevent loops caused by redundant paths. STP detects loops and blocks one or more redundant paths to ensure there is a loop-free topology in a bridged network. STP dynamically recalculates the topology if a link fails, reactivating previously blocked paths.
