68 A technician has installed a printer driver on a Windows 8 client computer. What is the best next step the technician can take to ensure that the printer is installed properly?
A. Ping the printer’s IP address.
B. Check the printer status and ensure it says “Ready.”
C. Stop and restart the spooler service.
D. Print a test page.

A. LVPS
B. HVPS
C. ACPS
D. Transfer corona assembly
70 You are connecting a laptop to a printer on the network using Wi-Fi. The user will need to use the printer frequently when they are in the office. What type of wireless connection will you establish with the printer?
A. Permanent
B. Ad hoc
C. On demand
D. Infrastructure

A. RAMCheck
B. BIOS
C. UEFI
D. POST
73 You have been asked to install and configure a RAID 10 storage array for a computer. What is the minimum number of hard disks required for this configuration?
A. 2
B. 3
C. 4
D. 5
74 Identify the peripheral connector shown here.

75 A technician is recommending that his company use removable memory cards. Which of the following should he tell his manager?
A. MiniSD and microSD cards work in a standard SD card slot.
B. MiniSD cards work in a standard SD slot, but microSD cards do not.
C. MicroSD cards work in a standard SD slot, but miniSD cards do not.
D. Neither miniSD nor microSD cards will work in a standard SD slot.
76 You are purchasing new laptops for your company. When thinking about the monitor quality, which type of backlight will produce better-quality pictures?
A. LED
B. СКАЧАТЬ
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.
A. MiniSD and microSD cards are smaller than standard SD memory cards. Adapters are available to allow them to work in standard SD slots.
A. There are two backlight technologies for LCD monitors: LED and fluorescent. Of the two, LED produces higher-quality images. OLED and plasma are display technologies, not backlight technologies.
