IT Essentials (Version 8.0) – ITE 8.0 Certification Checkpoint Exam Chapters 1 – 4 Answers
1. A user is building a new computer system. Why would the user select a DDR3?
- to diminish any electrostatic charge
- to attach a laser printer
- to install a memory module
- to attach a VR headset
2. What characteristic best describes an AR headset?
- a head-mounted device that superimposes images and audio over a real world image and can provide users immediate access to information about their real surroundings
- an output device that uses LED, LCD, or OLED technology
- a head-mounted device that provides head-motion and eye-tracking sensors and displays three-dimensional images
- an output device used to present information from a laptop onto a screen
3. A technician has installed a new second hard drive in a tower computer, but the drive does not show up in the BIOS. What are two things the technician should check first? (Choose two.)
- The drive works in another computer.
- The power supply outputs enough wattage.
- Data and power cables are attached.
- The drive has been partitioned.
- The drive port is enabled in the BIOS.
Explanation: If the BIOS cannot detect a drive, either the port is disabled in the BIOS or the cables are not attached securely. A tower computer can typically have a second hard drive installed without any power issues. The drive cannot be partitioned or formatted until the BIOS recognizes it.
4. Where would a technician use an RG-6 cable?
- when connecting a display to a PC
- when attaching a PC to a LAN
- when replacing cable TV cabling
- when attaching an external hard drive
Explanation: RG-6 is a type of coaxial cable used in cable TV installations.
5. A user is building a custom computer system and is trying to decide on components for the new system. The user does light to medium graphic design, programming, and gaming. Which two components would be appropriate for this type of machine? (Choose two.)
- integrated CPU
- maximum CPU cores
- dedicated video card
- SSD
- high speed mechanical drive
Explanation: Both a gaming and graphic design computer should have an SSD and high-end video card. The computer should have a multicore CPU, but this computer does not require the maximum number of cores that a virtualization computer would need.
6. A technician is installing memory into a computer and notices that there are two black memory slots and two blue memory slots. Which memory technology does this motherboard use?
- ECC
- parity
- dual channel
- DDR4
Explanation: Motherboards that support dual channel frequently color the memory slots so the technician knows to populate the same color slots with a matching pair of memory modules.
7. A user reports that when games are being played, the computer displays random blotches on the screen. What are two possible causes? (Choose two.)
- bad inverter
- failing power supply
- failing LCD backlight
- loose video cable
- GPU overheating
Explanation: Artifacts such as dots, lines, or patterns on a screen are typically caused by a failing video card, an underpowered or overheated GPU, a loose video cable, overclocked CPU, or outdated video driver.
8. A technician needs to purchase a storage drive that both connects directly to the PCIe bus and provides reliability. Which type of storage device would best meet these requirements?
- tape drive
- 2.5″ SSD
- NVMe M.2
- 2.5″ HDD
Explanation: An NVMe M.2 device is a type of SSD that attaches to the PCIe bus without requiring SATA connectors or special drivers.
9. Which statement describes a feature of SDRAM?
- It is able to support two writes and two reads per CPU clock cycle.
- It requires constant power to function.
- Its connector always has 240 pins.
- It can process overlapping instructions in parallel.
Explanation: SDRAM ( Synchronous Dynamic RAM) works in synchronization with the memory bus and has higher transfer rates because it can process overlapping instructions in parallel.
10. A technician is asked to configure a laptop for LoJack. What will the technician have to do to accomplish this task?
- Attach a physical cable through a special hardware loop that is part of the computer case.
- Install antimalware software.
- Perform special steps on the hard drive using the Disk Management tool.
- Enable it in BIOS.
Explanation: LoJack is a security option that can be enabled and used to track a stolen device such as a laptop.
11. Match the memory type to the feature. (Not all options are used.)
- It’s connector has 288 pins and has advanced error correction features –> DDR4 SDRAM
- It’s connector has 184 pins and is able to support two writes and two reads per CPU clock cycle. –> DDR SDRAM
- It’s connector has 240 pins and consumes 1.5 Volts of power. –> DDR3 SDRAM
- It’s connector has 240 pins and consumes 1.8 Volts of power. –> DDR2 SDRAM
12. A technician is researching how to troubleshoot a computer that reboots randomly. The research suggests that the technician should check the computer for distended capacitors. Where should the technician look for these?
- under the CPU
- on the motherboard
- on the memory module
- within the power supply
Explanation: Distended capacitors are motherboard components that look like they are bulging. They can leak and cause motherboard issues.
13. A company is deploying both thin and thick client computers. Which configuration step will a technician need to do on the thin clients that will most likely not be done on the thick clients?
- Connect the computer to the LAN.
- Connect the computer to the application server.
- Install additional RAM.
- Install local applications.
Explanation: A thick client is a normal corporate workstation. A thin client is usually a monitor, keyboard, mouse, and a computer with few or no ports and no hard drive. A thin client runs applications and possibly even the operating system from a centralized device such as a server. A corporate technician commonly uses imaging software to install both, but a thin client requires the technician to make the connection to an application server.
14. A user has the following requirements for a RAID drive:
- It must be magnetic.
- It must be fast.
- It must fit into a standard tower case.
Which drive type would meet the user requirements?
- 3.5 inch 15K drive
- SSD
- NVMe
- BD-RE
Explanation: A 3.5 inch drive is commonly used in a tower computer. 15 K is commonly used to represent 15,000 rpm drives which are very fast magnetic drives. Blu-ray drives are not used in a RAID configuration. SSD and NVMe use flash memory and are not mechanical drives.
