Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 48

A network engineer must improve bandwidth and resource utilization on the switches by stopping the inefficient flooding of frames on trunk ports where the frames are not needed. Which Cisco IOS feature can be used to achieve this task?

Answer options

• A. VTP pruning
• B. access list
• C. switchport trunk allowed VLAN
• D. VLAN access-map

Correct answer: A

Explanation

The correct answer is A, VTP pruning, which reduces unnecessary broadcast, multicast, and unknown unicast traffic on trunk links by only allowing relevant VLANs. The other options do not specifically address the issue of frame flooding on trunk ports as effectively as VTP pruning does.
