Dell EMC Associate – Information Storage and Management v4 — Question 23

What is an accurate statement about Storage Class Memory (SCM)?

Answer options

• A. SCM is faster than DRAM
• B. SCM read and write speeds are slower than flash
• C. SCM can be addressed at the bit or word level
• D. SCM has volatile memory

Correct answer: A

Explanation

The correct answer is A because Storage Class Memory (SCM) is designed to provide faster access speeds compared to DRAM. Option B is incorrect as SCM generally offers faster speeds than flash memory, while C is misleading since SCM can indeed be addressed at the bit or word level. Option D is incorrect because while some SCM types can be non-volatile, others can be volatile, thus making the statement not universally accurate.
