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.)
- dedicated video card
- integrated CPU
- SSD
- high speed mechanical drive
- maximum CPU cores
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.

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 has been partitioned.
- The drive works in another computer.
- Data and power cables are attached.
- The drive port is enabled in the BIOS.
- The power supply outputs enough wattage.
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.
-
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
- loose video cable
- failing LCD backlight
- GPU overheating
- failing power supply
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typically caused by a failing video card, an underpowered or overheated GPU, a loose video cable, overclocked CPU, or outdated video driver.

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
- BD-RE
- NVMe
- SSD
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.
-
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?
- Install additional RAM.
- Install local applications.
- Connect the computer to the LAN.
- Connect the computer to the application server.
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.

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

Explanation: Distended capacitors are motherboard components that look like they are bulging. They can leak and cause motherboard issues.
-
Where would a technician use an RG-6 cable?

Explanation: LoJack is a security option that can be enabled and used to track a stolen device such as a laptop.
-
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?
- 2.5″ HDD
- 2.5″ SSD
- tape drive
- NVMe M.2
Explanation: An NVMe M.2 device is a type of SSD that attaches to the PCIe bus without requiring SATA connectors or special drivers.
