A technician has several possible solutions to a reported server issue. Which of the following BEST represents how the technician should proceed with troubleshooting?

Question

Options

• ADetermine whether there is a common element in the symptoms causing multiple problems.
• BPerform a root cause analysis.
• CMake one change at a time and test.
• DDocument the findings, actions, and outcomes throughout the process.

• A

• B
  3% (1)
• C
  82% (28)
• D
  9% (3)

Explanation

Standard troubleshooting methodology requires making a single change at a time and then testing the result before making another change. This isolates cause and effect, ensuring the technician knows exactly which action resolved the issue. Making multiple simultaneous changes makes it impossible to determine the root cause. While root cause analysis (B) and documentation (D) are also important steps in the troubleshooting process, the question asks specifically how to proceed when applying possible solutions-and the answer is to test one change at a time. Option A describes identifying a common cause, which is part of the problem identification phase, not the solution phase.
