Question 7

A user complains that their smartphone photos take up too much space and that image quality is critical for printing. A technician explains that a particular image format uses lossy compression, which reduces file size by permanently discarding some image data. Which of the following formats is the technician describing?

Accepted Answer

JPEG. JPEG is the standard lossy image format that permanently removes some visual data to achieve smaller file sizes, making it suitable for photographs where slight quality loss is acceptable. The other formats either preserve all data or reduce colors without the same lossy compression mechanism. The technician's description of discarding image data to save space points directly to JPEG.

Answer

BMP

GIF

Answer

PNG

Question 8

A technician is setting up a new desktop computer and needs to install an operating system from a bootable USB flash drive. The computer powers on but boots directly into the existing hard drive instead of the USB drive. Which of the following should the technician configure to allow the computer to boot from the USB drive?

Accepted Answer

BIOS/UEFI boot order. The firmware boot order controls which device the computer attempts to boot from first. If the internal hard drive precedes the USB drive, the system skips the USB media. Reordering the boot sequence in BIOS/UEFI so the USB drive is first allows the installation media to load as needed.

Answer

Windows Device Manager

Answer

Task Scheduler

Answer

Disk Management console

Question 9

A user complains that their laptop battery drains quickly even when the laptop is idle. A technician suspects that a background process is consuming resources. Which of the following Windows tools should the technician use to identify the process consuming the most CPU or disk resources?

Accepted Answer

Task Manager. Task Manager is the built-in Windows utility that shows real-time resource usage by process. By sorting on CPU or disk columns, the technician can quickly identify a background process causing high usage and draining the battery. The other tools serve different purposes and do not provide per-process resource monitoring.

Answer

Question 14

A technician is explaining data representation to a trainee. The trainee asks which of the following statements correctly describe how bits and bytes are used in computing. (Choose two.)

Accepted Answer

A bit is the smallest unit of data and can have a value of 0 or 1.. A bit is the smallest unit of data, holding a 0 or 1, and a byte is 8 bits, capable of representing 256 values. These two statements accurately describe fundamental data representation. The other options incorrectly describe bit capacity, byte size, or binary-to-decimal mapping, so they are not correct.

Answer

A bit can represent decimal numbers directly without conversion.

Answer

A byte is always equal to 10 bits in modern computing systems.

Answer

A bit can store multiple characters, while a byte stores only one.

Question 15

A technician is setting up a small office network and needs to connect devices using a physical topology where each device connects to a central device, and a failure of one cable does not affect the others. Which topology should the technician implement?

Accepted Answer

Star topology. A star topology uses a central device to connect all nodes, so a single cable failure only affects the device on that cable. This provides the fault isolation and central management the technician needs. The other topologies either share a common backbone, form a loop, or require extensive redundant connections, none of which fit the described requirements.
