CompTIA DataX (CNX-001) — Question 17

A company is experiencing multiple switch failures. The network analyst discovers the following:
Network recovery time is unacceptable and occurs after the shutdown of some switches.
Some loops were detected in the network.
No broadcast storm was detected.
Which of the following is the most cost-effective solution?

Answer options

• A. Add a new Layer 3 switch.
• B. Add multiple VLANs.
• C. Implement STP.
• D. Implement tagging.

Correct answer: C

Explanation

Implementing STP (Spanning Tree Protocol) is the most cost-effective solution as it helps eliminate network loops and ensures stable network operation. Adding a new Layer 3 switch or creating multiple VLANs may incur additional costs without directly addressing the loop issue. Tagging does not resolve the underlying problems related to switch failures and loops.
