CompTIA Network+ (N10-008) — Question 149

An administrator would like to create a fault-tolerant ring between three switches within a Layer 2 network. Which of the following Ethernet features should the administrator employ?

Answer options

• A. Spanning Tree Protocol
• B. Open Shortest Path First
• C. Port mirroring
• D. An interior gateway protocol

Correct answer: A

Explanation

The Spanning Tree Protocol (STP) is specifically designed to prevent loops in Layer 2 networks by creating a loop-free topology. The other options, such as Open Shortest Path First (OSPF), are related to Layer 3 routing, while port mirroring is used for monitoring network traffic and not for fault tolerance.
