A network technician recently replaced a managed switch in an enterprise network with a new managed switch. Users on the switch can communicate with each other but now cannot access other network…

Question

Options

• AThe newly installed switch is defective and must be returned.
• BThe newly installed switch is using a different MAC address than the previous switch.
• CThe technician forgot to change the VTP mode on the new switch to server.
• DThe technician did not use the correct cable when trunking the new switch.

• A

• B

• D
  85% (11)

Explanation

The key symptom is that intra-switch communication works (same segment) but inter-segment communication fails. This points directly to a trunking problem. Trunk links carry traffic for multiple VLANs between switches and to routers, enabling inter-VLAN and inter-segment routing. If the trunk port is not correctly cabled (e.g., a wrong port was used or the port was not configured as a trunk), traffic cannot pass to other segments. A defective switch (A) would likely cause broader failures including local communication. A different MAC address (B) is normal and does not affect routing. VTP server mode (C) is used for VLAN propagation, but VTP misconfiguration alone would not block communication to other segments if VLANs were manually configured.
