Multiple choice

Refer to the exhibit. Hosts that are connected to switch SW1 are not able to communicate with hosts in the same VLAN that are connected to switch SW2. What should be done to fix the problem?

  1. Introduce a Layer 3 device in the topology.

  2. Configure both switches in VTP transparent mode to allow them to share VLAN information.

  3. Reconfigure the fa0/1 interface on switch SW1 with a static trunk configuration.

  4. Reconfigure the fa0/1 interface on switch SW1 with a static trunk configuration.

D Correct answer
Explanation

When hosts in the same VLAN on different switches cannot communicate, the issue is typically the trunk link between switches. Reconfiguring the interface with a static trunk configuration (rather than relying on DTP auto-negotiation) ensures the link becomes a trunk and carries all VLAN traffic. A Layer 3 device is not needed for same-VLAN communication. VTP transparent mode does not automatically create trunks.
