A PC technician has installed a new network printer that was preconfigured with the correct static IP address, subnet mask, and default gateway. The printer was
installed with a new cable and appears to have link activity, but the printer will not respond to any network communication attempts. Which of the following is MOST
likely the cause of the problem?
A.
Damaged cable
B.
Duplex mismatch
C.
Incorrect VLAN assignment
D.
Speed mismatch
Explanation:
If a port is accidentally assigned to the wrong VLAN in a switch, it’s as if that client was magically transported to another place in the network. This would explain the
inability to communication with the printer, as it is on a different VLAN.
How do we deduce that a vlan is in this equation w/o any information in the question indicating that this device configuration is part of a vlan? For myself I eliminated vlan because it wasn’t mentioned and selected “B. Duplex Mismatch.” had I known it was part of a vlan I would have made another choice. I get make it challenging but when the test questions intentionally leave out needed information this isn’t a test of understanding of the material, it’s more a case of “read the mind of the test developers.”
