Desktop Support Technician Interview Practice Test

Testing RAM for faults calls for a tool that specifically exercises memory and reports any errors found. Windows Memory Diagnostic is the built-in utility designed for this purpose. It runs a series of memory tests, usually after a restart, and then shows the results (often logged in the Event Viewer) indicating whether the RAM is healthy or has detected errors. This helps pinpoint faulty memory modules or timing issues, guiding you toward hardware replacement or configuration adjustments. The other utilities test something else entirely: Disk Defragmenter reorganizes data on storage drives to improve performance, SFC (System File Checker) verifies and repairs corrupted Windows system files, and DISM (Deployment Image Servicing and Management) repairs Windows images and components. They don’t perform RAM stress-testing or fault detection.
