Question 201.

Which type of computing device is designed primarily for portability and typically includes a built-in display, keyboard, and battery?

1. Laptop
   2. Rack server
   3. Desktop tower
   4. Network switch

Correct Answer: 1. Laptop

Explanation:

A laptop is designed for portable computing and usually combines a display, keyboard, pointing device, battery, storage, memory, and processor in one compact system. Desktop towers and rack servers are generally intended for fixed locations, while a network switch is a networking device rather than a personal computer. Portability makes laptops suitable for users who work in different locations, but battery life, thermal design, weight, and expandability are usually more constrained than on desktop systems.

Question 202.

Which device is commonly optimized for providing shared applications, files, or services to multiple users over a network?

1. Smartphone
   2. Server
   3. Keyboard
   4. Webcam

Correct Answer: 2. Server

Explanation:

A server is designed to provide services or resources to other computers and users over a network. Servers may host websites, databases, shared files, authentication services, virtual machines, or business applications. A smartphone is primarily a personal mobile device, while keyboards and webcams are peripherals. Servers are often built with reliability, scalability, redundancy, and centralized management in mind because many users may depend on the services they provide.

Question 203.

Which device category is designed primarily for handheld mobile communication and application use?

1. Desktop computer
   2. Rack server
   3. Smartphone
   4. Network appliance

Correct Answer: 3. Smartphone

Explanation:

A smartphone is a handheld computing device that combines mobile communication, internet access, applications, cameras, sensors, and touchscreen input. It commonly connects through cellular networks, Wi-Fi, Bluetooth, and NFC. Desktop computers and rack servers are intended for different computing roles, while network appliances provide specialized infrastructure functions. Smartphones are powerful general-purpose devices but usually have less expandability and smaller displays than traditional computers.

Question 204.

Which type of device is most likely to use a touchscreen as its primary input method while providing a larger display than a typical smartphone?

1. Server
   2. Desktop tower
   3. Switch
   4. Tablet**

Correct Answer: 4. Tablet

Explanation:

A tablet is a portable computing device with a touchscreen as its primary user interface. It generally provides a larger display than a smartphone while remaining more portable than many laptops. Tablets may support external keyboards, pens, cameras, and wireless connectivity. Servers, desktop towers, and switches are not primarily designed around touchscreen interaction. Tablets are commonly used for education, field work, entertainment, digital forms, and mobile productivity.

Question 205.

Which component is primarily responsible for rendering graphics and accelerating visual processing?

1. GPU
   2. PSU
   3. HDD
   4. NIC

Correct Answer: 1. GPU

Explanation:

A graphics processing unit, or GPU, is designed to process graphics and other highly parallel workloads. It renders images, video, 3D scenes, and user-interface elements and may also accelerate workloads such as machine learning or scientific calculations. The PSU supplies electrical power, the HDD stores data, and the NIC provides network connectivity. Some systems use integrated graphics built into the processor, while others use dedicated GPUs with their own memory.

Question 206.

Which hardware component allows a computer to connect to a wired or wireless network?

1. GPU
   2. Network interface controller
   3. CPU cooler
   4. Optical drive

Correct Answer: 2. Network interface controller

Explanation:

A network interface controller, or NIC, provides network connectivity. A wired NIC may connect through Ethernet, while a wireless NIC connects through Wi-Fi. The GPU handles graphics, CPU cooling removes processor heat, and optical drives read or write optical media. Many modern computers include both wired and wireless network interfaces. Correct drivers and network configuration are required for the NIC to communicate properly with switches, access points, routers, and other systems.

Question 207.

Which component helps remove heat directly from a processor?

1. SSD
   2. Speaker
   3. Heat sink and fan assembly
   4. Ethernet cable

Correct Answer: 3. Heat sink and fan assembly

Explanation:

A heat sink draws heat away from the processor, while a fan helps move warm air away from the heat sink and through the computer chassis. Some systems use liquid cooling or passive cooling instead. SSDs store data, speakers produce audio, and Ethernet cables carry network traffic. Proper cooling is critical because processors generate substantial heat under load, and excessive temperatures can reduce performance, cause instability, or trigger emergency shutdowns.

Question 208.

Which component stores frequently accessed processor data closer to the CPU than system RAM?

1. Optical disc
   2. HDD
   3. USB flash drive
   4. CPU cache**

Correct Answer: 4. CPU cache

Explanation:

CPU cache is high-speed memory located on or very close to the processor. It stores frequently used instructions and data so the CPU can access them more quickly than if it had to retrieve everything from system RAM. Cache is much smaller than RAM but much faster. Hard drives, optical discs, and USB flash storage are nonvolatile storage technologies and are considerably slower. Modern processors may include multiple levels of cache optimized for different performance needs.

Question 209.

Which operating system feature allows multiple user accounts to have different permissions on the same computer?

1. Access control
   2. Disk formatting
   3. Screen scaling
   4. File compression

Correct Answer: 1. Access control

Explanation:

Access control allows an operating system to determine which users or groups can access files, applications, devices, and system functions. Different accounts can therefore have different permissions. Formatting prepares storage media, scaling changes display presentation, and compression reduces file size. Proper access control supports least privilege and helps prevent users from viewing or changing resources they do not need. Administrative permissions should be limited to users who actually require them.

Question 210.

Which feature allows a user to lock a computer session without signing out or closing open applications?

1. Shutdown
   2. Screen lock
   3. Disk cleanup
   4. Formatting

Correct Answer: 2. Screen lock

Explanation:

A screen lock secures an active session while leaving applications and documents open. The user must authenticate again to regain access. This is useful when stepping away from a computer because it prevents casual unauthorized access without requiring a full sign-out or shutdown. Disk cleanup and formatting relate to storage, while shutdown powers off the system. Organizations often configure automatic screen locking after a period of inactivity as a basic security control.

Question 211.

Which operating system function allows users to install and remove software applications?

1. File compression
   2. Screen rotation
   3. Application management
   4. DNS only

Correct Answer: 3. Application management

Explanation:

Operating systems provide tools for installing, updating, configuring, and removing applications. These capabilities may appear through package managers, app stores, settings panels, or traditional installers. File compression and screen rotation serve different purposes, while DNS is a networking service. Application management is important for maintaining software compatibility and security. Users should install software only from trusted sources and should remove unsupported or unnecessary applications when appropriate.

Question 212.

Which operating system process is responsible for loading when the computer starts and providing the main environment for users and applications?

1. Printer driver
   2. Browser extension
   3. Spreadsheet macro
   4. Boot process**

Correct Answer: 4. Boot process

Explanation:

The boot process begins when the computer is powered on and continues through firmware initialization, boot-device selection, operating system loading, and startup of essential services. Printer drivers, browser extensions, and spreadsheet macros may load later but do not describe the overall startup sequence. Understanding the boot process helps troubleshoot systems that fail to start, display boot errors, or cannot locate an operating system.

Question 213.

Which file operation creates an additional copy of a file while leaving the original in place?

1. Copy
   2. Move
   3. Delete
   4. Rename

Correct Answer: 1. Copy

Explanation:

Copying a file creates a second instance while leaving the original file in its existing location. Moving transfers the file to a new location, deleting removes it, and renaming changes its name. Copy operations are useful when creating working duplicates, transferring information, or preparing backups. Users should still ensure that sensitive files are copied only to authorized locations because duplicate data may create additional security and privacy risks.

Question 214.

Which file operation changes a file’s location without intentionally creating a second persistent copy?

1. Delete
   2. Move
   3. Compress
   4. Encrypt

Correct Answer: 2. Move

Explanation:

Moving a file changes its location, such as transferring it from one folder to another. In normal use, the file is no longer present at the original location after the move completes. Copying, in contrast, leaves the original and creates another copy. Compression reduces file size, while encryption protects confidentiality. Understanding basic file operations helps users organize data and avoid accidental duplication or loss.

Question 215.

Which file attribute is commonly used to help prevent accidental modification of a file?

1. Hidden only
   2. System only
   3. Read-only
   4. Temporary only

Correct Answer: 3. Read-only

Explanation:

A read-only attribute indicates that a file should not normally be modified. It can help reduce accidental changes, although it should not be treated as a strong security control because users with sufficient permissions may be able to change the attribute. Hidden and system attributes serve different organizational or operating-system purposes. Strong protection of sensitive data should rely on proper access permissions, encryption, backups, and other security controls rather than file attributes alone.

Question 216.

Which file-management practice best reduces the chance of losing important documents due to accidental deletion or hardware failure?

1. Store everything in one location
   2. Disable version history
   3. Never copy files
   4. Maintain regular backups**

Correct Answer: 4. Maintain regular backups

Explanation:

Regular backups provide additional copies of important files that can be used if the originals are deleted, corrupted, encrypted by ransomware, or lost because of hardware failure. Keeping everything in one location creates a single point of failure. Backups should ideally include multiple copies, separate storage locations, and periodic restore testing. Version history can also help recover earlier file versions, but it should not be the only protection against serious data-loss events.

Question 217.

Which protocol is primarily used to translate domain names into IP addresses?

1. DNS
   2. DHCP
   3. SMTP
   4. FTP

Correct Answer: 1. DNS

Explanation:

DNS translates human-readable domain names into IP addresses used by computers for network communication. For example, users can enter a website name instead of memorizing its numerical address. DHCP automatically provides network configuration, SMTP sends email, and FTP transfers files. A DNS problem may cause websites and services to fail by name even when direct IP connectivity continues to work.

Question 218.

Which service normally assigns IP addresses and other network settings automatically to clients?

1. DNS
   2. DHCP
   3. HTTPS
   4. SSH

Correct Answer: 2. DHCP

Explanation:

DHCP automatically assigns IP configuration to network clients. This commonly includes an IP address, subnet information, default gateway, and DNS server addresses. DNS provides name resolution, HTTPS secures web traffic, and SSH provides encrypted remote command-line access. DHCP simplifies network administration because users do not need to configure every device manually. If DHCP fails, a client may receive a link-local address and lose normal access to network resources.

Question 219.

Which security control helps protect data from unauthorized disclosure while it is stored on a lost laptop?

1. Compression
   2. Defragmentation
   3. Full-disk encryption
   4. Screen brightness adjustment

Correct Answer: 3. Full-disk encryption

Explanation:

Full-disk encryption protects data stored on a drive by converting it into an unreadable form that requires authorized credentials or cryptographic keys to access. This is especially useful for laptops because portable devices can be lost or stolen. Compression and defragmentation do not provide confidentiality. A screen lock is also useful, but full-disk encryption provides stronger protection against someone removing the storage device or attempting offline access.

Question 220.

A computer can access other systems on the local network but cannot reach any internet destinations. Which configuration should be checked first?

1. Monitor resolution
   2. Audio volume
   3. Printer settings
   4. Default gateway**

Correct Answer: 4. Default gateway

Explanation:

The default gateway is used to forward traffic from the local subnet to remote networks. If local communication works but all remote IP connectivity fails, an incorrect or missing default gateway is a likely cause. The technician should inspect the computer’s IP configuration and compare it with known working devices. Monitor, audio, and printer settings do not affect routing. If the gateway is correct, the investigation can continue with router availability, upstream connectivity, DNS, and other network services.
