Designing Cisco Enterprise Networks (ENSLD) — Question 38

An engineer must design a large Layer 2 domain that contains hundreds of switches and VLANs. The engineer's primary goals are to:
✑ Efficiently utilize the bandwidth of all links
✑ Avoid Layer 2 loops
✑ Cause minimal impact on switch CPU and memory
Which technology should the engineer include in the design?

Answer options

• A. MST
• B. Rapid PVST+
• C. RSTP
• D. PVST+

Correct answer: A

Explanation

The correct choice is MST (Multiple Spanning Tree), as it allows for the efficient use of bandwidth across multiple VLANs while minimizing CPU and memory usage. Rapid PVST+, RSTP, and PVST+ do not provide the same level of efficiency in managing multiple VLANs and can potentially lead to higher resource consumption or slower convergence times.
