A network technician has been tasked with deploying new VoIP phones on a network. When the technician plugs the Ethernet cable for the phone into the wall port, the phone fails to turn on. When the technician plugs the Ethernet cable directly into the computer, the computer is able to access the network. Which of the following is the MOST likely cause of this issue?
- A.
The network switch does not support PoE
- B.
The technician is connecting the phone to the wrong type of port
- C.
The firewall on the network is blocking access to the DHCP server
- D.
The Ethernet cable is the wrong type
Correct Answer
A. The network switch does not support PoEExplanation
The most likely cause of the issue is that the network switch does not support PoE (Power over Ethernet). PoE is required to provide power to the VoIP phone through the Ethernet cable. Since the phone fails to turn on when connected to the wall port, it suggests that the switch is not providing the necessary power. When the Ethernet cable is connected directly to the computer, which does not require PoE, it is able to access the network.Rate this question:

A user is notified of file system errors on an external hard drive. Which of the following tools can be used to repair common errors on the drive?
- A.
Chkdsk
- B.
Diskpart
- C.
Format
- D.
Sfc

An office printer that was working earlier in the day is no longer printing any documents. Pre-existing workstations are manually configured to print to the printer directly over the network. A technician has started to troubleshoot the problem and determines that the printer can still be seen in the network directory. The technician has also verified that the printer can print self-diagnostic pages successfully. Which of the following is the MOST likely cause of the problem?
- A.
The printer's IP address has changed
- B.
The network print spooler service has been restarted
- C.
"Perform Printer Maintenance" message is displayed on the printer’s LCD panel
- D.
Two or more users sent print jobs simultaneously, causing a print collision
Correct Answer
A. The printer's IP address has changedExplanation
The most likely cause of the problem is that the printer's IP address has changed. This would explain why the pre-existing workstations are no longer able to print to the printer directly over the network. The fact that the printer can still be seen in the network directory and can print self-diagnostic pages successfully suggests that the printer itself is functioning properly. Therefore, the issue is likely related to a change in the printer's IP address, which would require reconfiguring the workstations to print to the new IP address.Rate this question:
