VLANs 50 and 60 exist on the trunk links between all switches All access ports on SW3 are configured for VLAN 50 and SW1 is the VTP server.

Which command ensures that SW3 receives frames only from VLAN 50?

Answer: A

Explanation:

VTP pruning enhances network bandwidth use by reducing unnecessary flood traffic. It does not forward broadcasts intended for VLANs across trunk links if there are no active ports in that VLAN on the downstream switches. So, enabling VTP pruning on SW1 ensures that SW3 receives frames only from VLAN 50 as all its access ports are configured for VLAN 50.
