SK0-005 · Question #109

A server is experiencing heavy disk thrashing due to a need for more memory. A manager asks the server technician to install 32GB of static RAM on the server. The technician tells the manager this…

The correct answer is B. static RAM does not come in this size. The technician's statement is correct because static RAM (SRAM) is significantly more expensive and less dense than dynamic RAM (DRAM), making large capacities like 32GB impractical and generally unavailable for main system memory.

Question

A server is experiencing heavy disk thrashing due to a need for more memory. A manager asks the server technician to install 32GB of static RAM on the server. The technician tells the manager this is incorrect because:

Options

  • Athe RAM used in this case is dynamic RAM.
  • Bstatic RAM does not come in this size.
  • Cdynamic RAM is used for CMOS.
  • Dstatic RAM needs a refresh cycle.

Why each option

The technician's statement is correct because static RAM (SRAM) is significantly more expensive and less dense than dynamic RAM (DRAM), making large capacities like 32GB impractical and generally unavailable for main system memory.

Athe RAM used in this case is dynamic RAM.

While it is true that the main system memory used in servers is dynamic RAM, stating "the RAM used in this case is dynamic RAM" does not directly explain why the manager's request for static RAM in that size is incorrect.

Bstatic RAM does not come in this size.Correct

Static RAM (SRAM) is very fast and does not require a refresh cycle, but it is much more complex, expensive, and less dense than Dynamic RAM (DRAM). For main system memory in servers and PCs, large capacities like 32GB are exclusively fulfilled by DRAM modules due to their cost-effectiveness and high density, making 32GB of static RAM an impractical and non-existent offering for this purpose.

Cdynamic RAM is used for CMOS.

CMOS (Complementary Metal-Oxide-Semiconductor) memory is typically a very small, non-volatile memory that stores BIOS settings, and it does not use dynamic RAM.

Dstatic RAM needs a refresh cycle.

This statement is incorrect; static RAM (SRAM) does not need a refresh cycle, which is one of its distinguishing characteristics from dynamic RAM (DRAM).
