CIS 106 Unit 5 Assessment
3.5 - 3.7
1.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?
A. Buffered memory is faster and less expensive.
B. Buffered memory reduces the load on the memory controller, but due to the extra clock cycle, is less
stable.
C. Buffered memory increases the load on the memory controller, but is faster and more stable.
D. Buffered memory reduces the load on the memory controller and allows the system to be more stable.
2. What are the advantages of DDR4 over DDR3, assuming the same operating frequency? (Select two.)
DDR4 includes a buffer between the data bus and the memory.
DDR4 doubles the data transfer rate of DDR3.
DDR4 uses less power than DDR3.
DDR4 accepts sixteen consecutive 64-bit words per bus clock cycle.
DDR4 accepts four consecutive 64-bit words per bus clock cycle.
3. As a computer technician, you are troubleshooting a client's computer that is experiencing intermittent crashes
and sudden reboots. The client reports that these issues started happening after a recent memory upgrade.
You have already confirmed that the new memory modules are compatible with the system and are properly
installed.
What would be the next BEST step to diagnose the issue?
A. Install a new operating system on the computer.
B. Run a memory diagnostic tool to check for any memory errors.
C. Check the system's power supply for any fluctuations.
D. Check the system for any software bugs.
4. After installing two memory modules, you power on the system to check for errors. You find that the BIOS
program recognizes only one of the memory modules.
Which of the following is BEST to try first when troubleshooting this issue?
A. Scan for new devices in Device Manager and enable any disabled memory modules.
