CompTIA A+ Core 1 (220-1201)HardwareMedium
A technician is troubleshooting a server that intermittently fails to boot, sometimes displaying memory-related errors. The server uses DDR4 RAM. The technician suspects a memory issue. Which of the following tools should the technician use FIRST to diagnose potential problems with the RAM modules?
- ALoopback adapter
- BMemory diagnostic software
- CMultimeter
- DPOST card
Show answer & explanationAnswer & explanation
Correct answer: B. Memory diagnostic software
Memory diagnostic software (like MemTest86 or Windows Memory Diagnostic) is specifically designed to thoroughly test RAM modules for errors, patterns, and integrity, making it the most appropriate first tool for diagnosing suspected memory issues.
Why the other options are wrong
- A. A loopback adapter is used for testing network interface cards (NICs) by sending and receiving data on the same port.
- C. A multimeter measures electrical properties like voltage, current, and resistance, useful for power supply or circuit testing, not direct RAM integrity.
- D. A POST card displays diagnostic codes during the Power-On Self-Test (POST), which can indicate a general area of failure but doesn't specifically test RAM integrity in detail.
Memory Diagnostic Software
Software tools designed to test the integrity and functionality of RAM modules by performing various read/write patterns and checks.
- Identifies faulty RAM modules.
- Runs comprehensive tests.
- Can be bootable from USB or included in OS.
Memory trick: Memory errors? Diagnostic software knows the answers.
