CompTIA A+ Core 1 (220-1001) — Question 3

A server needs a RAM upgrade, and a technician has been tasked with retrieving the RAM from storage and then installing it.
Which of the following is the BEST RAM type for the technician to retrieve?

Answer options

• A. SoDIMM
• B. DDR4
• C. Single channel
• D. ECC

Correct answer: D

Explanation

ECC (Error-Correcting Code) RAM is the best choice for servers because it can detect and correct data corruption, enhancing system stability and reliability. While DDR4 is a type of RAM, it does not inherently include error correction, making it less suitable for critical server applications. SoDIMM refers to a form factor and not a type, and single channel indicates a configuration rather than a specific RAM type.
