Refer to the exhibit. A network engineer must configure communication between PC A and the File Server. To avoid interrupting any other communications, which command must be configured?

  • A switchport truck allowed vlan 12
  • B switchport truck allowed vlan none
  • C switchport truck allowed vlan add 13
  • D switchport truck allowed vlan remove 10-11
Explanation

PC A and the File Server are both assigned to VLAN 13 on their access ports, so VLAN 13 must be permitted across the trunk link between Switch A and Switch B for their traffic to pass. The existing trunk configuration on Switch A allows only VLANs 10 through 12, which blocks VLAN 13. Using the command to add VLAN 13 preserves the currently allowed VLANs and enables the needed connectivity without affecting other VLAN traffic.
