A user is having problems printing. The technician believes the printer may be out of ink. Which of the following troubleshooting steps should be performed NEXT?

Options

AEstablish a plan of action to resolve the problem
BImplement the solution
CTest the theory to determine cause
DVerify full system functionality

Explanation

The CompTIA A+ troubleshooting methodology follows a defined order: (1) Identify the problem, (2) Establish a theory of probable cause, (3) Test the theory to determine cause, (4) Establish a plan of action, (5) Implement the solution, (6) Verify full system functionality, (7) Document findings. In this scenario, the technician has already completed steps 1 and 2 - the problem is identified and a theory (out of ink) has been formed. The NEXT logical step is step 3: test the theory, for example by checking ink levels in the printer software or physically inspecting the cartridge. You should not create a plan of action or implement a solution until you've confirmed your theory is correct.
