______ constructs a tree to eliminate loops on the switching network. A. SPOF B. NAT C. Redundancy D. STP

Breakdown the Problem

1. Identify what is meant by constructing a tree to eliminate loops in switching networks.
2. Analyze the options provided to determine which most accurately fits the definition of creating a loop-free topology.

Relevant Concepts

• The process of creating a loop-free network topology often involves specific protocols or methodologies aimed at preventing broadcast storms and ensuring data packets can traverse the network efficiently without looping back.
• Loop prevention mechanisms are crucial in network design.

Analysis and Detail

1. SPOF (Single Point of Failure): Refers to a point in a system where a failure will stop the entire system from working. While important, it does not directly relate to creating loops in a switching network.

2. NAT (Network Address Translation): A method used to modify network address information while in transit. It does not deal with the loop structures in switching networks.

3. Redundancy: This concept involves having multiple instances of critical components or functions to increase reliability. While related to network design, it doesn't specifically construct a tree structure to eliminate loops.

4. STP (Spanning Tree Protocol): This is specifically designed to prevent loops in a network by creating a spanning tree that selectively blocks certain ports to ensure there are no cycles.

Verify and Summarize

After analyzing each option, it becomes apparent that STP (Spanning Tree Protocol) is the correct answer since its main function is to construct a loop-free topology in Ethernet networks.

Final Answer

D. STP (Spanning Tree Protocol) is the correct answer, as it constructs a tree to eliminate loops in the switching network.
