A, D. Intel’s Virtualization Technology (Intel VT) is needed to support virtualization. It’s enabled in the BIOS, not the operating system.

A. Graphic design (or CAD/CAM) workstations require solid CPU power, RAM, and a high-end video card. Hard drive storage is the least important upgrade for these types of users.

C. The most common analog video connector is a VGA connector.

A. Refresh rate defines the vertical scan frequency of a monitor and determines how many times, in one second, an image can be redrawn on the screen. Many LCD monitors have a fixed refresh rate.

D. Thunderbolt v1 and v2 both provide 20Gbps of data bandwidth. In addition, Thunderbolt ports power the attached peripherals with 18V and 9.9W of power.

B. The fuser heats up to approximately 350° Fahrenheit. Do not touch it as it will cause burns!

B. A standard thick client is not really a custom configuration; it’s the standard configuration on which custom configurations are based. In other words, a thick client is a standard client computer system.

C. The order of steps is processing, charging, exposing, developing, transferring, fusing, and cleaning.

B, C. PCI slots and adapters are manufactured in 3.3V and 5V versions. Adapters are keyed to fit in a slot based on their voltage requirements. Universal adapters are keyed to fit in slots based on either of the two voltages.

A. Trusted Platform Module (TPM) is an international standard for a dedicated security coprocessor, or cryptoprocessor. Coupled with a BIOS, it can be configured to boot the system only after authenticating the boot device.

A. The transfer corona assembly is given a high-voltage charge, which is transferred to the paper, which in turn pulls the toner from the photosensitive imaging drum.

C. This is an eight-pin PCIe connector. They also come in 6-pin configurations.

D. After installing a new printer, it’s good practice to print a test page to ensure functionality.

B. The high-voltage power supply (HVPS) provides the high voltages used by both the charging corona and the transfer corona during the laser printing process.

D. Wi-Fi (802.11a, b, g, n, or ac) and Bluetooth can be used to connect a printer temporarily to a single computer (or mobile device), and the connection does not have permanent status. This type of configuration is known as an ad hoc network connection. When Wi-Fi is used to connect printers to a network on a more permanent basis, it is known as infrastructure mode.

C. PCI-X version 2.0 introduced the current maximum bus speed, 533MHz. With an 8-byte (64-bit) bus, this translates to maximum throughput of 4266MBps, roughly 4.3GBps.

D. The power-on-self-test (POST) is a series of system checks performed by the system BIOS. Checking the system memory is part of the POST routine.

C. RAID 10 (also known as RAID 1+0) provides fault tolerance to RAID 0 through the RAID 1 mirroring of each disk in the RAID 0 striped set. It requires four hard disks.

C. The image is of a SATA connector, commonly used for internal hard drives.
