A field service technician is replacing a server motherboard that supports CPUs with multithreading capabilities. The technician notices the motherboard has four processor sockets. If each socket supports a quad-core processor, how many logical processors does the system appear to have? 4 8 16 32

32 (4 CPUs x 4 Cores per CPU x 2 threads per core).

For maximum efficiency and performance, a highly tuned and specialized application needs to run on a system capable of handling exactly 16 threads at the same time from the operating system. Which two of the following will best meet the specified requirement? A motherboard with four dual-core processors A system board with two quad-core processors A system with a 64-bit operating system installed A system board with four quad-core processors A motherboard with two 8-core processors

A motherboard with four dual-core processors A system board with two quad-core processors

What is the most likely result of a correctly installed processor, but an incorrectly installed cooler? Powers on, stays on, but the system freezes and nothing else happens Boot process begins, but the system suddenly turns off after a short period You press the power button, but the system does not power on at all BIOS/UEFI setup does not recognize the processor correctly

Boot process begins, but the system suddenly turns off after a short period

You are reviewing new RAM to purchase for a gaming computer and find three different RAM modules that are the same except for their CL rating.The memory with which rating will work best? CL15 CL18 CL20 They will all perform at the same speed.

A customer takes a computer to a repair shop because the system did not boot successfully after adding a memory module to help increase performance. What is likely to be the problem? Two different manufacturer's memory are installed The memory modules operate at different speeds One memory stick in unbuffered, the other is registered One of the memory slots has been left unpopulated

One memory stick in unbuffered, the other is registered

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

PC4 32000

An entrepreneur wants to design and produce memory modules that meet industry specifications. To increase memory performance in servers the module should use technology to hold and amplify the signal just before the data is written to the module. What technology should the memory modules include? ECC Registers Parity CAS

Registers

When selecting a processor to match system needs, what features should you NOT consider? Reviews of processors, including benchmarks and comparisons to other processors Processor's ability to multitask, the number of cores, and multithreading abilities and which programs can make use of the abilities Balancing the performance and power of the CPU with the entire system, including graphics adaptors and hard drives The latest and most powerful processor available because the performance benefit will far outweigh the cost

The latest and most powerful processor available because the performance benefit will far outweigh the cost

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

The system will run as expected with no problems at all

Gina is upgrading your computer with a new processor. She installs the processor into your motherboard and adds the cooling system. She powers up the computer, and it begins to boot but then shuts down.What could be the cause of this problem? Computer is overclocked. Thermal compound was not used. Processor is not compatible. Processor is not seated properly.

Thermal compound was not used.

Joanna is researching high-end motherboards for a gaming computer with the best performance possible. Which consideration should be highest on the list?
