Multiple choice

Refer to the exhibit. The network administrator has just added VLAN 50 to Switch1 and Switch2 and assigned hosts on the IP addresses of the VLAN in the 10.1.50.0/24 subnet range. Computer A can communicate with computer B, but not with computer C or computer D. What is the most likely cause of this problem?

  1. There is a native VLAN mismatch.

  2. The link between Switch1 and Switch2 is up but not trunked.

  3. The is not properly configured for inter-VLAN routing.

  4. VLAN 50 is not allowed to entering the trunk between Switch1 and Switch2.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

If Computer A can communicate with Computer B (likely on the same switch) but not with C or D (on the other switch), the trunk link between switches isn't carrying VLAN 50 traffic. By default, trunks carry all VLANs unless explicitly restricted. If VLAN 50 was previously removed from the allowed list or the trunk wasn't properly configured, inter-switch communication for that VLAN fails. Native VLAN mismatch (A) would cause different errors. A non-trunked link (B) wouldn't allow any VLAN traffic to pass.
