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:
Incorrect VLAN assignment? Why is this the answer?
prolly cos if the printer is in the wrong vlan it won’t receive messages from hosts outside the vlan. so if PC-A needs to print and is on VLAN-1 but the printer is on VLAN-2 without additional configuration the printer won’t receive the message
The new cable is a key to ignore A, the speed and duplex mismatch may cause issues but will not drop all communication so we can assume it is on a different VLAN and this is why there is no communication attempts made. Even with duplex mismatch or speed mismatch we could ping the printer, if it does not respond to any communication then we can use deductive reasoning to point to C.
But in real world , sometimes even a brand new product comes defective out of box
appears to have link activity. if cable bad no link light.
