CompTIA Tech+ (FC0-U71)IT Concepts and TerminologyEasy
A technician is troubleshooting a network connectivity issue. After verifying the physical connections, they ping a known good IP address on the local network and receive no response. Which of the following is the MOST appropriate next step in a standard troubleshooting methodology?
- AVerify full system functionality.
- BImplement a solution and test it.
- CEstablish a theory of probable cause.
- DDocument findings, actions, and outcomes.
Show answer & explanationAnswer & explanation
Correct answer: C. Establish a theory of probable cause.
After identifying the problem (no ping response) and gathering initial information (physical connections verified), the next logical step in troubleshooting is to establish a theory about why the problem is occurring.
Why the other options are wrong
- A. Verifying full system functionality comes after a solution has been implemented and tested.
- B. Implementing a solution is premature before a theory is established and tested.
- D. Documentation is the final step in the troubleshooting process, after a solution is confirmed.
Troubleshooting Methodology
A systematic approach to diagnosing and resolving problems in a logical and efficient manner.
- Follows a structured sequence of steps.
- Aims to identify root causes, not just symptoms.
- Ensures consistent and effective problem resolution.
