You have an older computer that has four DDR2 memory slots. Currently, there are two 512-MB memory modules installed. You check the motherboard documentation and find that the system has a 4-GB memory limitation. You want to add more memory to this system. What is the maximum total amount of usable RAM you can have in this system by adding new memory modules (and without replacing the existing memory modules)?

3gb

You want to build a new system that supports 16 GB of memory. Which of the following is the MOST important consideration when building the computer?

64-Bit Processor

You work as the IT administrator for a small corporate network. Sam, an employee in the support department, wants to run a virtual machine on his computer for troubleshooting customer issues, and he needs a very stable computer from which to work. You need to decide whether to install buffered or non-buffered RAM in his computer. Which of the following BEST describes the reason to choose buffered instead of unbuffered memory for this new computer?

Buffered memory reduces the load on the memory controller and allows the system to be more stable

With a memory module read request, there is a delay between the time of the data request and the time the data is available for output from the memory module. What is this delay called?

CAS latency

You are in a carpeted office lighted by fluorescent bulbs. You are preparing to add memory modules to a user's computer. The user has already unpacked the memory modules and stacked them on top of an old, unused CRT monitor. What is the greatest threat to these memory modules in this environment?

Electrostatic Discharge

Which of the following is the most common method for removing RAM from a motherboard?

Move the tabs holding the RAM out of the way, then pull straight up to remove the RAM

You have an existing system that has a single DDR3 memory module installed. You would like to add more memory to the three remaining empty memory slots. Which of the following steps should you take to make sure that you get the right memory for the system? (Select two.)

Purchase additional modules that are the same as what is currently installed. Check the mnotherboard documentation to find which modules are supported.

Which of the following statements is true regarding single- and double-sided memory?

Single-Sided memory uses half the number of memory modules as double-sided memory of the same capacity

You have just upgraded the memory in one of your network servers by adding two 4-GB ECC memory cards. Before purchasing the new memory, you made sure that the modules fit in the memory slots (packaging) and the speed (memory frequency) was supported by the memory controller. What did you forget to check that would significantly impact the memory checking of your new ECC memory cards?

Whether or not the existing memory modules support ECC

You are trying to push a memory module into a memory slot, but it is not seating properly. What is the MOST likely issue?

You are trying to install the memory module backwards in the memory slot.
