• The motherboard has failed

• The video card has failed

You have implemented a solution that resolved an audio problem on a laptop computer.

Following the best practice methodology, what is the next step to take?

• Vertify full system functionality and , if applicable, implement preventive measures

• Document findings, action, and outcomes

• Review system and application logs

• Establish a plan of action to resolve the problem

You have been troubleshooting a laptop for an hour and have established a theory of probable cause for the problem.

What is the next step you should take?

• Document findings, actions, and outcomes

• Test the theory to determine the cause

• Establish a plan of action to resolve the problem

• Vertify full system functionality and implement preventive measures

You are using the best practice methodology to troubelshoot a video problem.

During which step should you question the obvious?

• Establigh a theory of probable cause

• Test the theory to determine the cause

• Establish a plan of action to resolve the problem

• Identify the problem

You have fixed a printer problem and verified full functionality.

What is the next step to take in the best practice methodology?

• Document findings, actions, and outcomes

• Establish a theory of probable cause

• Review system and application logs

• Conduct internal or external research

You turn on a desktop computer and it fails to boot.

You hear a rhythmic ticking coming from inside the case.

What is most like the problem?

• Failed motherboard

• Failed hard drive

• Failed RAM

• Failed CPU

Answer explanation

Only components with moving parts can make ticking or clicking noises. This question assumes the hard drive is a HDD (hard disk drive) and not an SSD (solid state drive), but none of the components would make a ticking noise
