Exam 220-1101 topic 1 question 113 discussion

I think B is correct. He has established a theory "technician thinks a desktop PC has failed due to a defective power supply." I think the question wants us to assume he has already completed step 1.

I think it's actually A. The suggested answer is step 2 of troubleshooting method and so far he hasn't completed any step in troubleshoot methodology.

Step 1: Identify the Problem Step 2: Establish a Theory Step 3: Test the Theory Step 4: Establish a Plan of Action Step 5: Verify Functionality Step 6: Document Findings They just finished step 2. C (Plan of Action) would skip to step 4. I guess research is considered part of step 3 (Testing)?

The technician thinks what the problem is doesnt mean he has identified. Step 1 is to Identify the problem by gathering information and asking questions. and then establish therory

According to the CompTIA troubleshooting methodology, the next step after establishing a theory of probable cause is to test the theory to determine the cause. However, before testing the theory, the technician may need to conduct some research based on the symptoms and the possible cause. This may involve consulting online resources, manuals, documentation, or colleagues to find out more information about the power supply and how to test it. Research can help the technician confirm or eliminate the theory and avoid unnecessary actions or damage.

B or C ? Once the technician has determined that the power supply is likely to be defective, they should establish a plan of action to resolve the problem. This may include replacing the power supply or further testing to confirm that it is indeed defective. After establishing a plan of action, the technician should implement the solution and verify that it has resolved the issue.

B Once the technician suspects a power supply issue, the next logical step is to verify the hypothesis by researching the symptoms and performing diagnostics.

Identify the problem - System failure Establish a theory of probable cause- The power supply is problematic Test the theory to determine the cause - Conducting research based on the symptoms (B) Establish a plan of action- Replace the power supply

the answer is B this involves gathering more information about the symptoms observed and possibly looking up common issues related to power supply failures in desktop pcs. this research should help the tech confirm or rule out the possibility of a defective power supply and gather insights into troubleshooting steps.

The answer is B because he did step 2, which is establish a theory. The next step is test the theory, which also includes conducting research based on symptoms.

Test the theory to determine the cause. This is step three for COMPTIA's troubleshooting process.

B. Conduct external or internal research based on symptoms: Investigate the symptoms related to the power supply failure. Check for common signs such as no power, flickering LEDs, or abnormal noises. Research possible causes and solutions related to power supply issues.

I hate this question lol

Through research, the technician might be able to determine if power is the issue.

After trying to plug it into another wall socket, if the PC doesn't turn on, I'd think the PSU is dead. Can't imagine what environmental or infrastructure changes could lead to a dead PSU (NOT A) & I can't think of what there could be on the internet to research about a dead PSU (NOT B). It's kinda like a burned out light bulb. Somethings you fix; somethings you just replace. When the remote control fails, do ask Siri questions?

• Step 1: Identify the problem • Step 2: Establish a theory of probable cause • Step 3: Test the theory to determine the cause • Step 4: Establish a plan of action to resolve the problem and implement the solution So: C&D are not correct since he did not do step 3 which is test the theory. A is more likely the answer since Inquire about environmental or infrastructure changes is part of testing the theory which is defective power supply. For example, the devise might moved to another room with different voltage which cause a power supply.

Answer is B
