Designing Cisco Enterprise Networks (ENSLD) — Question 35

A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:
* reduce the impact of topology changes
* reduce the time spent on network administration
* reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)

Answer options

• A. Implement Rapid PVST+ instead of STP.
• B. Implement MST instead of STP.
• C. Use VTP to propagate VLAN information and to prune unused VLANs.
• D. Configure broadcast and multicast storm control on all switches.
• E. Configure dynamic trunking protocol to propagate VLAN information.

Correct answer: A, C

Explanation

Rapid PVST+ (A) allows for faster convergence times compared to STP, helping to reduce the impact of topology changes. Using VTP (C) simplifies VLAN management by automatically distributing VLAN information across switches, which reduces manual errors and administrative overhead. The other options do not directly address the goals of reducing topology impact or administrative time effectively.
