What three characteristics are true about SRAM and DRAM?

• SRAM and DRAM both need to be refreshed with the same frequency

• Both are considered volatile because they only hold data while power is on

• SRAM is faster than DRAM because it does not need to be refreshed

• DRAM is closer to the CPU than SRAM because it has a 64-bit data path

• The type of memory used in a memory cache is SRAM because it is faster

An organization wants to increase the amount of RAM on their computers. All the computers have four memory slots but only two slots in each computer are populated. They want to add one more memory module to the older computers, and two additional modules to the newer computers. The older computers have three blue slots and one black slot. Which memory type will maximize the number of DIMMS the memory controller can access at the same time in both, the older and newer computers?

• DDR

• DDR2

• DDR3

• DDR4

A computer has four DDR4 memory modules. Two modules have a speed of 3000 MHz and the other two have a speed of 4000 MHz. If the two 3000 MHz DIMMs are upgraded, the new modules to be installed should have what rating?

• PC4 24000

• PC4 25600

• PC4 28800

• PC4 32000

Tomi buys a CPU from a computer store. The retail box references the amount of L1 cache in the list of features. What is it referring to?

• The maximum amount of memory the processor can access

• The memory in the CPU package, but not on the processor die

• The amount of memory residing directly on the processor die

• The memory between the CPU package and the DIMM slots

A system administrator boots a Windows PC using a Live Linux CD/DVD and list the files on the system. One of the files is called pagefile.sys. What is this file used for? Select all that apply.

• Windows normally stores virtual memory in this file.

• Windows stores filesystem information in this file.

• Used to enhance the amount of RAM in the system.

• It is a type of cache to backup up the contents of UEFI.

• Mirrors the contents of RAM to improve performance.

You are able to successfully install new DIMMs with a data path that have 72 bits in a server using a 64-bit processor. Which of the following is true regarding this scenario?

• The system will issue an error message and not power up

• It is not possible to fit a 72-bit DIMM in a 64-bit system

• The system will power on but then shutdown right away

• The system will run as expected with no problems at all
