You have just installed a new network printer in a customers

You have just installed a new network printer in a customer’s office. You connect your laptop to the printer using a USB cable, and it prints fine. However, when your customer attempts to connect and print over the network, he can’t do so. You check the computer’s network configuration and physical network connections, and everything is fine. You check the IP address you’ve given the printer as well as its physical connections, and they are correct. You try to ping the printer’s IP address from the customer’s computer, but the request times out. Of the following, what could be wrong?

A. The printer is configured to use the wrong DHCP server.

B. The printer is configured to use the wrong DNS server.

C. The printer is configured to use the wrong NAT server.

D. The printer is configured to use the wrong subnet mask.

Solution

D. A subnet mask defines the specific network to which an IP address belongs. It is expressed similarly to the way an IPv4 address is expressed. A common subnet mask is 255.255.255.0. If this setting is missing or entered incorrectly onto a device that has a manual network configuration, the device will not be able to be reached over the network.
