Question 41

Which component stores the operating system and user files when the computer is powered off?

1. CPU cache
2. RAM
3. Storage drive
4. System bus

Correct Answer: 3

Explanation

A storage drive provides nonvolatile storage for the operating system, applications, documents, and other user data. Common storage devices include solid-state drives and hard disk drives. Unlike RAM and CPU cache, storage retains information when the computer is powered off. The system bus provides communication pathways between components rather than serving as permanent storage. Storage capacity is typically measured in gigabytes or terabytes. When troubleshooting insufficient disk space or planning a storage upgrade, the technician should evaluate the drive’s capacity, interface, performance, and compatibility with the system.

Question 42

Which wireless standard is commonly used for short-range connections between a computer and devices such as keyboards, mice, and headsets?

1. Bluetooth
2. Wi-Fi 6E
3. NFC
4. Cellular

Correct Answer: 1

Explanation

Bluetooth is designed for short-range wireless personal-area connections and is commonly used with peripherals such as keyboards, mice, headphones, speakers, and game controllers. It generally consumes less power than technologies designed for broader wireless networking and does not require a traditional network infrastructure for basic device-to-device communication. Wi-Fi is primarily designed for network connectivity, NFC operates over a very short distance for applications such as pairing and contactless transactions, and cellular technology provides wide-area connectivity. Bluetooth is therefore the most suitable choice for common wireless peripherals.

Question 43

A technician needs to install a replacement motherboard. Which information is most important when selecting a compatible replacement?

1. Mouse DPI
2. Case form factor and supported CPU socket
3. Printer resolution
4. Monitor speaker wattage

Correct Answer: 2

Explanation

When replacing a motherboard, the technician must verify compatibility with the computer case and processor. The motherboard’s form factor, such as ATX, Micro-ATX, or Mini-ITX, determines whether it will physically fit in the case. The CPU socket and chipset determine which processors are supported. The technician should also consider RAM compatibility, expansion slots, storage interfaces, firmware requirements, and available connectors. Mouse DPI, printer resolution, and monitor speaker specifications do not determine motherboard compatibility. Proper planning prevents installation problems and ensures the replacement board supports the system’s existing components.

Question 44

Which technology is commonly used to create a virtual machine that runs independently of the host operating system environment?

1. RAID
2. Virtualization
3. Spooling
4. Defragmentation

Correct Answer: 2

Explanation

Virtualization allows a physical computer to host one or more virtual machines that operate as separate computing environments. A hypervisor manages the allocation of resources such as CPU processing, memory, storage, and networking to virtual machines. This technology is useful for testing operating systems, consolidating servers, running isolated workloads, and supporting development environments. RAID combines physical storage devices, spooling temporarily queues jobs, and defragmentation reorganizes file data on certain storage systems. Therefore, virtualization is the technology responsible for creating and managing virtual machine environments.

Question 45

Which component provides temporary working space for programs and data currently being used by the operating system?

1. RAM
2. SSD
3. CMOS battery
4. Optical disc

Correct Answer: 1

Explanation

Random Access Memory (RAM) provides temporary working space for the operating system, applications, and data currently being processed. RAM is volatile, meaning its contents are lost when system power is removed. Having sufficient RAM can improve multitasking and reduce the need for the operating system to rely heavily on slower storage for memory management. An SSD provides persistent storage, a CMOS battery helps maintain certain firmware settings and system time, and an optical disc provides removable storage. Therefore, RAM is the primary working memory used by active applications and processes.

Question 46

A user wants to transfer photos from a smartphone to a laptop without using a cable and without joining a wireless network. Which technology may be appropriate for a very short-range transfer?

1. Ethernet
2. NFC
3. SATA
4. HDMI

Correct Answer: 2

Explanation

Near Field Communication (NFC) is designed for very short-range wireless communication and can support certain device-to-device interactions and data exchanges. Depending on the devices and operating systems involved, NFC may be used to initiate pairing or facilitate small amounts of information transfer. It is not intended for large file transfers over long distances. Ethernet requires a physical network cable, SATA is primarily an internal storage interface, and HDMI is designed for audio and video transmission. NFC is therefore the technology most closely associated with extremely short-range wireless communication.

Question 47

Which connector is designed to provide a reversible USB connection commonly found on modern laptops and smartphones?

1. USB Type-A
2. Micro-USB
3. USB Type-C
4. Mini-USB

Correct Answer: 3

Explanation

USB Type-C is a small, reversible connector used extensively on modern laptops, smartphones, tablets, docking stations, and peripherals. Its reversible design means the connector can be inserted in either orientation. Depending on the implementation, USB Type-C can support data transfer, charging, video output, and other functions through technologies such as USB, DisplayPort Alt Mode, and USB Power Delivery. USB Type-A is larger and not reversible, while Micro-USB and Mini-USB are older connector designs. Therefore, USB Type-C is the appropriate connector for the described modern devices.

Question 48

Which security technology can be used to securely erase data from a storage device so that ordinary recovery methods cannot retrieve it?

1. Data sanitization
2. File compression
3. Disk partitioning
4. Screen locking

Correct Answer: 1

Explanation

Data sanitization is the process of securely removing information from a storage device so that the original data cannot be reasonably recovered using normal methods. The appropriate sanitization technique depends on the type of storage device and organizational requirements. For example, secure erase commands or cryptographic erase may be appropriate for certain SSDs. File compression only changes how data is stored, partitioning organizes storage areas, and screen locking protects access to an active system but does not remove stored information. Secure sanitization is essential when disposing of or repurposing sensitive storage devices.

Question 49

Which printer type is generally well suited for producing high-volume black-and-white documents quickly?

1. Inkjet
2. Laser
3. Thermal receipt printer
4. 3D printer

Correct Answer: 2

Explanation

Laser printers are commonly used for high-volume document printing because they can produce text quickly and efficiently. They use toner rather than liquid ink and typically offer fast print speeds, sharp text output, and relatively low per-page costs for many office workloads. Inkjet printers are often useful for color images and photo printing, while thermal receipt printers are specialized for transaction receipts. A 3D printer creates physical objects rather than conventional paper documents. For large quantities of black-and-white business documents, a laser printer is generally a suitable choice.

Question 50

A technician receives a report that a computer has become extremely slow after many applications were installed. Which resource should be checked to determine whether the system is running low on memory?

1. RAM utilization
2. Monitor resolution
3. Printer queue
4. BIOS logo

Correct Answer: 1

Explanation

RAM utilization should be checked when investigating whether insufficient memory is contributing to poor system performance. Running many applications simultaneously can consume a large amount of available RAM. When physical memory becomes limited, the operating system may use storage as virtual memory, which is considerably slower than physical RAM and can result in noticeable performance degradation. Monitoring memory usage helps determine whether a RAM upgrade or application-management change may be appropriate. Monitor resolution, printer queues, and the BIOS logo do not directly indicate whether the system is experiencing memory pressure.

Question 51

Which component connects a computer to a wireless network when wireless capability is not integrated into the motherboard?

1. Wireless NIC
2. Sound card
3. Capture card
4. RAID controller

Correct Answer: 1

Explanation

A wireless Network Interface Card (NIC) provides the hardware required for Wi-Fi communication when wireless networking is not already integrated into the computer. Wireless NICs may be installed as internal expansion cards, M.2 modules, or external USB adapters depending on the system. They communicate with wireless access points and routers using supported Wi-Fi standards. A sound card handles audio processing, a capture card handles incoming audio or video signals, and a RAID controller manages certain storage configurations. Therefore, a wireless NIC is the appropriate hardware for adding Wi-Fi connectivity.

Question 52

Which feature allows a computer to start an operating system from a network instead of local storage?

1. PXE
2. HDMI
3. RAID
4. TPM

Correct Answer: 1

Explanation

Preboot Execution Environment (PXE) allows a compatible computer to obtain startup information and potentially boot an operating system or deployment environment from a network. PXE is commonly used in enterprise environments for operating system deployment, imaging, diagnostics, and centralized management. The computer’s firmware initializes the network interface and communicates with appropriate network services during the boot process. HDMI is a display interface, RAID manages storage configurations, and TPM provides hardware-based security functions. PXE is therefore the technology associated with network-based booting.

Question 53

Which hardware component is responsible for converting digital audio data into an analog signal for traditional speakers or headphones?

1. GPU
2. NIC
3. Sound card
4. RAM

Correct Answer: 3

Explanation

A sound card or integrated audio controller handles audio processing and conversion between digital and analog signals. When digital audio needs to be played through traditional analog speakers or headphones, the digital-to-analog conversion allows the electrical audio signal to be delivered through an appropriate analog output. A GPU processes graphics, a NIC handles network communication, and RAM provides temporary working memory. Modern motherboards often include integrated audio hardware rather than requiring a separate sound card. Nevertheless, the audio subsystem performs the conversion required for traditional analog output.

Question 54

A technician wants to protect a workstation from brief voltage spikes but does not need battery backup. Which device is appropriate?

1. UPS
2. Surge protector
3. KVM switch
4. Docking station

Correct Answer: 2

Explanation

A surge protector is designed to help protect connected electrical equipment from voltage spikes and transient increases in electrical power. It is appropriate when the primary requirement is protection from electrical surges rather than continued operation during an outage. A UPS also provides surge protection on many models but additionally supplies battery-backed power when utility power fails. A KVM switch controls multiple computers using shared peripherals, while a docking station expands connectivity for compatible computers. Therefore, when battery backup is not required and surge protection is the main goal, a surge protector is appropriate.

Question 55

Which connector is commonly associated with older analog computer displays?

1. VGA
2. USB-C
3. DisplayPort
4. HDMI

Correct Answer: 1

Explanation

VGA is an older analog video interface historically used to connect computers to monitors and projectors. It commonly uses a 15-pin connector and transmits analog video signals. Modern systems increasingly use digital interfaces such as HDMI, DisplayPort, and USB-C with compatible display modes. Because VGA is analog, image quality can be more susceptible to signal degradation compared with modern digital connections, especially at higher resolutions. Although still encountered on legacy equipment, VGA is considered an older display technology and is less common on current consumer hardware.

Question 56

Which mobile device feature allows users to unlock a device using a fingerprint or facial characteristic?

1. Biometric authentication
2. Virtual memory
3. RAID
4. Screen mirroring

Correct Answer: 1

Explanation

Biometric authentication uses measurable physical characteristics to verify a user’s identity. Common examples include fingerprint recognition and facial recognition. Mobile devices may use dedicated sensors, cameras, or other hardware to capture biometric information and compare it with previously enrolled authentication data. Virtual memory concerns memory management, RAID concerns storage configurations, and screen mirroring allows display content to be shown on another compatible screen. Biometric authentication can provide a convenient additional security mechanism, although organizations should still consider alternative authentication methods and the security requirements of the device.

Question 57

A technician needs to connect several USB devices to a laptop that has only one available USB port. Which device can expand the number of available USB connections?

1. Network switch
2. USB hub
3. Modem
4. KVM switch

Correct Answer: 2

Explanation

A USB hub allows multiple USB devices to share a single USB port on a computer. Hubs are useful when a laptop or desktop has fewer physical USB ports than the user needs for peripherals such as keyboards, mice, external storage, and other accessories. Some hubs are bus-powered, while others include their own external power supply for devices requiring more power. A network switch provides Ethernet connectivity, a modem provides network service conversion, and a KVM switch controls multiple computers. Therefore, a USB hub is the appropriate solution for expanding USB connectivity.

Question 58

Which storage interface is commonly associated with traditional internal hard drives and 2.5-inch SATA SSDs?

1. SATA
2. HDMI
3. PCIe x16
4. Bluetooth

Correct Answer: 1

Explanation

SATA is a widely used storage interface for traditional internal hard disk drives and SATA-based solid-state drives. It uses separate data and power connections and has been common in desktop and laptop systems for many years. SATA SSDs offer faster performance than traditional hard drives while retaining compatibility with SATA-based systems. HDMI is a digital display interface, PCIe x16 is commonly used for graphics cards, and Bluetooth provides wireless communication. Therefore, SATA is the interface most directly associated with conventional internal SATA storage devices.

Question 59

Which troubleshooting step helps determine whether a newly installed device is causing a system problem?

1. Remove the device and test the system
2. Delete all user accounts
3. Replace the operating system immediately
4. Disable all security controls permanently

Correct Answer: 1

Explanation

If a problem begins after installing a new hardware device, temporarily removing the device and testing the system can help determine whether it is related to the issue. This process is useful for isolating the cause while avoiding unnecessary replacement of unrelated components. If the problem disappears after removing the device, the technician can investigate compatibility, drivers, firmware, installation, and hardware condition. Deleting accounts, reinstalling the operating system, or permanently disabling security controls are excessive responses that can introduce additional risks without establishing the root cause.

Question 60

Which practice is most important when handling a customer’s computer that contains confidential personal information?

1. Share the files with other technicians
2. Copy all documents to a personal drive
3. Follow privacy and data-handling procedures
4. Disable the user’s password

Correct Answer: 3

Explanation

Technicians may encounter sensitive information such as personal documents, financial records, credentials, or business data while servicing computers. Following established privacy and data-handling procedures helps protect this information from unauthorized access or disclosure. Technicians should access only the information necessary to perform the assigned work and should follow organizational policies regarding storage, transfer, and disposal of customer data. Sharing files unnecessarily, copying data to personal storage, or disabling passwords creates significant security and privacy risks. Proper data-handling practices are therefore an essential part of professional technical support.
