Question 221

Which motherboard component provides the electrical connection between the CPU and the motherboard?

1. CPU socket
2. DIMM slot
3. PCIe slot
4. CMOS battery

Correct Answer: 1

Explanation

The CPU socket provides the physical and electrical interface between the processor and motherboard. It is designed for a specific processor socket type and must match the CPU being installed. The socket contains contacts that allow communication and power delivery between the processor and motherboard circuitry. DIMM slots are used for memory, PCIe slots accommodate expansion devices, and the CMOS battery maintains certain firmware configuration settings and real-time clock information. Therefore, the CPU socket is the component that connects the processor to the motherboard.

Question 222

Which storage interface is commonly associated with modern 2.5-inch SATA solid-state drives?

1. PCIe
2. SATA
3. USB
4. SCSI

Correct Answer: 2

Explanation

A 2.5-inch SATA SSD commonly uses the Serial ATA interface for communication with the motherboard or storage controller. These drives typically use separate SATA data and SATA power connections. SATA SSDs are widely used as replacements for traditional 2.5-inch hard disk drives and offer faster access times because they use flash memory. PCIe is used by NVMe storage devices, USB is an external peripheral interface, and SCSI is an older storage technology. Therefore, SATA is the appropriate interface for the described drive.

Question 223

Which device allows multiple computers to connect to a local network and forwards Ethernet frames based on MAC addresses?

1. Router
2. Modem
3. Switch
4. Repeater

Correct Answer: 3

Explanation

A network switch connects multiple devices within a local Ethernet network and forwards frames based on destination MAC addresses. By learning which MAC addresses are associated with specific ports, the switch can send traffic toward the appropriate destination rather than broadcasting every frame across all ports. A router connects different IP networks, a modem provides communication with certain service-provider networks, and a repeater regenerates or extends signals. Therefore, a switch is the device responsible for forwarding Ethernet frames using MAC-address information.

Question 224

Which wireless frequency band generally provides greater range and better penetration through obstacles than the higher-frequency 5 GHz band?

1. 2.4 GHz
2. 5 GHz
3. 6 GHz
4. 60 GHz

Correct Answer: 1

Explanation

The 2.4 GHz Wi-Fi band generally provides longer range and better penetration through walls and other obstacles than higher-frequency bands such as 5 GHz and 6 GHz. However, 2.4 GHz can experience more interference because many devices use this frequency range, and it typically offers fewer non-overlapping channels. Higher-frequency bands can provide greater throughput under suitable conditions but usually have shorter effective range. Therefore, when range and obstacle penetration are the primary considerations, 2.4 GHz is generally the more suitable band.

Question 225

Which printer component uses heat to fuse toner onto paper during laser printing?

1. Transfer roller
2. Pickup roller
3. Fuser assembly
4. Imaging drum

Correct Answer: 3

Explanation

The fuser assembly in a laser printer uses heat and pressure to permanently bond toner particles to the paper. After toner is transferred onto the page, the paper passes through the fuser, where the toner is melted or fused into the paper surface. The imaging drum forms the image pattern, the transfer roller helps move toner from the drum toward the paper, and the pickup roller feeds paper from the tray. Therefore, the fuser assembly performs the final toner-fusing process.

Question 226

Which display technology uses organic compounds that emit their own light rather than requiring a separate backlight?

1. LCD
2. OLED
3. CRT
4. DLP

Correct Answer: 2

Explanation

OLED, or Organic Light-Emitting Diode, displays use organic compounds that emit light when electrical current passes through them. Because individual pixels can generate their own light, OLED panels do not require a conventional separate backlight like LCD displays. This design can provide deep black levels, high contrast, and thin display construction. CRT displays use electron beams and phosphors, while DLP is a projection technology based on microscopic mirrors. Therefore, OLED is the display technology described in the question.

Question 227

A laptop shuts down immediately when its AC adapter is disconnected even though the battery indicator shows a high charge level. What is the most likely issue?

1. Failed battery
2. Damaged display panel
3. Incorrect keyboard layout
4. Faulty touchpad

Correct Answer: 1

Explanation

If a laptop immediately powers off when external AC power is removed despite displaying a high battery percentage, the battery may be unable to provide usable power. A battery can report an inaccurate charge level because of degraded cells, calibration problems, or internal failure. The technician should verify the battery health, charging behavior, and system power-management information. A display panel, keyboard layout, or touchpad problem would not normally cause immediate power loss when the adapter is disconnected. Therefore, a failed or severely degraded battery is the most likely cause.

Question 228

Which port is commonly used to connect a computer to a Gigabit Ethernet network using twisted-pair cabling?

1. RJ11
2. USB-A
3. RJ45
4. VGA

Explanation

RJ45-style connectors are commonly used for Ethernet networking over twisted-pair copper cables. Gigabit Ethernet can operate over compatible twisted-pair cabling such as Cat 5e or higher, depending on the installation requirements. RJ11 connectors are generally associated with telephone wiring, USB-A is a general-purpose peripheral connector, and VGA is an analog video interface. When troubleshooting a wired network connection, the technician should verify that the Ethernet cable is properly connected to the RJ45 network port and that the link indicators behave as expected.

Question 229

Which component stores firmware configuration information and helps maintain the system clock when the computer is powered off?

1. CMOS battery
2. RAM
3. GPU memory
4. CPU cache

Correct Answer: 1

Explanation

The CMOS battery supplies a small amount of power to the motherboard circuitry responsible for maintaining certain firmware settings and the real-time clock when the computer is turned off. A weak or failed battery can result in incorrect date and time values or loss of certain firmware configuration settings after power is removed. RAM loses its contents when power is removed, GPU memory is used for graphics processing, and CPU cache supports fast processor operations. Therefore, the CMOS battery supports the described functionality.

Question 230

1. VGA
2. HDMI
3. PS/2
4. RJ11

Correct Answer: 2

Explanation

HDMI, or High-Definition Multimedia Interface, carries digital video and audio through a single cable. It is widely used with televisions, monitors, gaming systems, streaming devices, receivers, and computers. HDMI supports various video resolutions and audio formats depending on the version and connected equipment. VGA carries analog video and does not normally carry digital audio, while PS/2 is a legacy keyboard or mouse interface and RJ11 is associated with telephone connections. Therefore, HDMI is the appropriate interface for combined digital audio and video.

Question 231

Which expansion slot is most commonly used for a dedicated modern graphics card?

1. PCIe x16
2. PCIe x1
3. DIMM
4. M.2

Correct Answer: 1

Explanation

A PCI Express x16 slot is commonly used for dedicated graphics cards because it provides a high-bandwidth connection between the GPU and motherboard. The physical slot is longer than lower-lane PCIe slots and is designed to accommodate devices requiring substantial data throughput. PCIe x1 slots are typically used for lower-bandwidth expansion devices, while DIMM slots hold system memory and M.2 slots commonly accommodate compact storage or other compatible devices. Therefore, PCIe x16 is the standard expansion slot for a dedicated graphics card.

Question 232

Which wireless technology is commonly used for connecting a keyboard or mouse over a short distance without a cable?

1. GPS
2. NFC
3. Bluetooth
4. Cellular

Correct Answer: 3

Explanation

Bluetooth is commonly used to connect wireless keyboards, mice, headsets, speakers, and other peripherals over relatively short distances. It is designed for low-power personal-area networking and allows compatible devices to communicate without a physical cable. GPS provides location information, NFC is intended for very short-range communication such as contactless transactions, and cellular technology provides wide-area mobile connectivity. Therefore, Bluetooth is the appropriate wireless technology for a typical wireless keyboard or mouse.

Question 233

Which command can be used to verify whether a remote host responds to ICMP echo requests?

1. nslookup
2. ping
3. ipconfig
4. netstat

Correct Answer: 2

Explanation

The ping command sends ICMP echo requests to a specified destination and waits for echo replies when the destination and network permit them. It is commonly used to test basic network reachability and measure response times. A successful ping can indicate that the destination is reachable, although it does not prove that every service on the remote system is functioning. Nslookup focuses on DNS resolution, ipconfig displays local network configuration, and netstat displays network connections and listening ports. Therefore, ping is appropriate for this connectivity test.

Question 234

Which Windows utility can be used to inspect warnings and errors recorded by the operating system?

1. Disk Management
2. Task Scheduler
3. Event Viewer
4. Device Manager

Correct Answer: 3

Explanation

Event Viewer provides access to Windows event logs that contain information about system activity, application events, security events, warnings, and errors. Technicians can use these logs to investigate system crashes, service failures, driver issues, authentication events, and other problems. Disk Management manages storage volumes, Task Scheduler manages scheduled tasks, and Device Manager displays hardware devices and driver status. Therefore, Event Viewer is the appropriate utility for reviewing operating-system warnings and errors.

Question 235

Which backup type saves all selected files each time it runs, regardless of when they were last backed up?

1. Incremental
2. Differential
3. Full
4. Snapshot

Correct Answer: 3

Explanation

A full backup copies all selected data during each backup operation. Because every selected file is included, a full backup generally requires more storage space and can take longer to complete than incremental or differential backups. However, restoration is usually simpler because the required data can be obtained from a single full backup set. Incremental backups contain changes since the previous backup, while differential backups contain changes since the last full backup. Therefore, a full backup matches the described behavior.

Question 236

Which security principle ensures that a user receives only the permissions necessary to perform assigned tasks?

1. Least privilege
2. Open access
3. Shared credentials
4. Full administrative control

Correct Answer: 1

Explanation

The principle of least privilege requires users, applications, and services to receive only the permissions necessary to perform their authorized tasks. Limiting privileges reduces the potential impact of compromised accounts, malicious software, accidental changes, and unauthorized actions. For example, a standard user does not normally need unrestricted administrative rights to perform routine work. Shared credentials and excessive permissions make accountability and security more difficult. Therefore, least privilege is the security principle that restricts access according to the minimum requirements of the assigned role.

Question 237

Which connector is commonly used for a fiber-optic network connection and uses a small form factor with a latch mechanism?

1. RJ45
2. LC
3. RJ11
4. USB-B

Correct Answer: 2

Explanation

The LC connector is a small-form-factor fiber-optic connector commonly used in network infrastructure. It uses a latch mechanism and is popular in environments where high-density fiber connections are required. RJ45 is primarily associated with twisted-pair Ethernet, RJ11 is commonly used for telephone connections, and USB-B is used for certain computer peripherals and devices. Fiber connections can use several connector types, including LC and SC, depending on the equipment and installation. Therefore, LC is the connector described in the question.

Question 238

Which type of memory is volatile and loses its stored contents when system power is removed?

1. SSD
2. ROM
3. RAM
4. Flash memory

Correct Answer: 3

Explanation

RAM, or Random Access Memory, is volatile memory because it requires continuous electrical power to retain its contents. It temporarily stores data and instructions that the CPU needs while applications are running. When the computer is powered off, information stored in RAM is normally lost. SSDs and flash memory are nonvolatile storage technologies, while ROM is designed to retain information without continuous power. Therefore, RAM is the memory type that loses its contents when system power is removed.

Question 239

Which network device forwards traffic between different IP networks and commonly serves as the default gateway for clients?

1. Switch
2. Access point
3. Router
4. Hub

Correct Answer: 3

Explanation

A router forwards packets between different IP networks and commonly provides the default gateway used by clients to reach destinations outside their local subnet. Routers examine IP addressing information and determine an appropriate path for network traffic. A switch primarily connects devices within a local Ethernet network, an access point provides wireless network connectivity, and a hub repeats traffic to connected ports without making forwarding decisions based on destination addresses. Therefore, a router is the device responsible for routing traffic between different IP networks.

Question 240

A technician replaces a defective component and confirms that the computer now operates normally. What should be done next?

1. Immediately replace another component
2. Document the repair and update the ticket
3. Delete all system logs
4. Disable security controls

Correct Answer: 2

Explanation

After resolving a hardware problem, the technician should document the work performed and update the service ticket or relevant records. Documentation should generally include the identified problem, troubleshooting steps, component replaced, corrective action, and verification that the system is functioning correctly. Accurate records support future troubleshooting, organizational knowledge, asset tracking, and accountability. Replacing additional components without justification or disabling security controls can create unnecessary risks. Therefore, documenting the successful repair and updating the ticket is the appropriate next step.
