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

<p>57</p>

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.

<p>58</p>

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

<p>59</p>

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.

<p>60</p>

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.

<p>61</p>

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

<p>62</p>

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.

<p>63</p>

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

<p>64</p>

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.

<p>65</p>

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.

<p>66</p>

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.

<p>67</p>

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

<p>68</p>

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

<p>69</p>

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.

<p>70</p>

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.

<p>71</p>

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.

<p>72</p>

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.

<p>73</p>

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.

<p>74</p>

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