An IT technician is resolving an issue where a workstation intermittently drops wireless network connectivity following a recent system update. Place the following troubleshooting steps performed by the technician in the correct sequential order according to the standard CompTIA troubleshooting methodology.
- 1Interview the affected user to gather details regarding when the connectivity drops occur and review the system update history log.
- 2Formulate a hypothesis that an updated wireless network adapter driver is causing signal instability.
- 3Roll back the network adapter driver to the previous stable version to confirm if the drops cease.
- 4Run continuous network throughput tests to verify that the workstation maintains a stable wireless connection without dropping.
- 5Log the root cause, driver rollback procedure, and final test results in the organization's ticketing database.
Cevap
The correct order follows the standard CompTIA troubleshooting methodology: 1) Interview the user and check update history (Identify the problem), 2) Formulate a hypothesis regarding the driver update (Establish a theory of probable cause), 3) Roll back the driver to test if the issue resolves (Test the theory), 4) Run continuous throughput tests (Verify full system functionality), and 5) Log the resolution details in the ticketing system (Document findings, actions, and outcomes).
The standard CompTIA 6-step troubleshooting methodology follows a mandatory sequence: 1. Identify the problem (interviewing the user and reviewing logs), 2. Establish a theory of probable cause (hypothesizing driver issues), 3. Test the theory to determine cause (rolling back the driver), 4. Establish a plan of action / implement solution, 5. Verify full system functionality (running throughput tests), and 6. Document findings, actions, and outcomes (logging details into the database).
