• During installation, install the 32-bit compatibility drivers

• Edit the BIOS and configure the processor to run in 32-bit mode.

• Replace the processor with a 32-bit processor.

• Install the application normally.

When using Intel chips, which of the following features BEST allows a single processor to run two threads in parallel instead of processing single threads linearly?

• Multi-processing

• Dual core

• Hyper-threading

• Overclocking

Which of the following refers to placing two processors on a single processor chip or die?

• Multi-core

• Multi-processor

• Multi-threading

• Hyper-threading

Which of the following is a characteristic of a multi-processor system?

• Ability to use over 4 GB of memory

• Multiple processor sockets on the motherboard

• Multiple cores on the same die

• Shared L2 cache

Assuming all other processor specifications are the same, which of the following processor sizes will consume the least amount of power?

• 45 nm

• 90 nm

• 65 nm

• 32 nm

Brian is a new employee on the development team. As part of his job, he runs three virtual machines (VMs) on his computer. Each VM runs a different Windows license. After a while, Brian notices that his VMs are not running as fast as he thought. He has asked you to explore the issue. Which of the following BEST describes why Brian's VMs are running slowly?

• Brian's computer has a quad-core processor, but hyper-threading has not been configured.

• Brian's computer has two physical CPUs, but hyper-threading has not been configured

• Brian's computer has a single dual-core CPU containing two central processing units.

• Brian's computer has a single-core CPU configured to use hyper-threading.

Which of the following BEST describes the purpose of a CPU socket?

• A CPU socket allows computer memory (RAM) to be inserted in the computer.

• A CPU socket is used to expand the computer's functionality, like a video card, network card, or sound card.

• A CPU socket is a single connector between a microprocessor and the motherboard.

• A CPU socket allows you to connect external devices such as your monitor, speakers, keyboard, and mouse.

You are in the process of purchasing several new computers to replace broken or outdated computers. After much research, you have determined to purchase computers that use AMD sockets. Which of the following BEST describes an AMD and why you would select this option? (Select TWO).

• Typically, AMD chips are less expensive.

• Typically, an AMD uses a land grid array (LGA) socket type.

• Typically, an AMD has a larger market share.

• Typically, an AMD uses a Pin Grid Array (PGA) socket type.

• Typically, an AMD uses numbers to represent the number of pins on the socket.

Your motherboard has two memory slots and supports a maximum of 8 GB of RAM. You are using a 32-bit version of Windows. After installing two 4 GB modules and booting your system, you find that Windows only recognizes 3.5 GB of RAM. Which of the following would MOST likely fix this issue?

• Upgrade to a 64-bit version of Windows.

• Make sure that both modules are seated properly in their slots.

• Reboot the computer and run memory diagnostic tests on the memory.

• Change the memory timings in the BIOS to a slower (higher) setting.

• Return both modules for a replacement.

Your computer has one single core processor installed. The motherboard supports processors with up to four cores. You want to upgrade your computer to a quad-core system. Which of the following will be part of your configuration?

• Configure the system to use dual channel memory

• Add a second processor that matches the speed of the first processor.

• Remove the terminating resistor from slots where the new processor will be installed.

• Replace the existing processor.
