CompTIA A+ Core 1 (220-1001) — Question 151

A workstation's RAM is being upgraded to 24GB. The system has six RAM slots supporting DDR4 dual-channel, with a maximum of 32GB total system memory.
Which of the following configurations will maximize system performance?

Answer options

• A. Two 4GB DDR4 chips and one 16GB DDR4 chip
• B. Two 8GB DDR4 chips and one 8GB DDR4 chips
• C. Four 8GB DDR2 chips
• D. Six 4GB DDR4 chips

Correct answer: D

Explanation

Option D is correct because using six 4GB DDR4 modules allows the system to take full advantage of the dual-channel architecture for optimal memory performance. The other options either do not utilize all available slots or include incompatible RAM types, such as DDR2 in option C, which would not work in a DDR4 system.
