You work for a small city IT department and the customers in City Hall complain that they can’t print to the network printer in their area. You go to one of the customer’s computers and try to ping the IP address of the printer, but this test fails. Of the following, what could be the problem? (Choose three.)

A. The printer is turned off.

B. The printer’s NIC is disabled.

C. The printer’s network cable is loose.

D. The DHCP server has issued the printer the wrong IP address.

Solution

A and D. An access point, like any other computing device that runs software, is subject to bugs that cause errors in behavior. One such possible bug can result in an authentication failure. Updating the WAP’s firmware to the latest version can apply whatever bug fixes the WAP manufacturer has created. Also, sometimes a person can leave caps lock on when typing a username and password, resulting in authentication failure.
