A technician plans to upgrade a laptop's RAM from 4GB to 16GB. Which of the following should the technician do?

The correct answer is A. Purchase the same architecture of RAM.. RAM architecture (e.g., DDR3, DDR4, DDR5, LPDDR5) determines the physical slot design, voltage requirements, and signaling standard. A laptop's memory slots are built for one specific architecture, and only that architecture will physically fit and function. This is the single mo

Explanation

RAM architecture (e.g., DDR3, DDR4, DDR5, LPDDR5) determines the physical slot design, voltage requirements, and signaling standard. A laptop's memory slots are built for one specific architecture, and only that architecture will physically fit and function. This is the single most critical requirement when purchasing replacement or upgrade RAM. Configuring BIOS settings (B) is typically not required as modern systems auto-detect RAM. Matching CAS latency (C) can be beneficial for performance but is not required for compatibility. Matching brand (D) has no technical significance for compatibility.
