Question 341

Which motherboard feature allows a technician to install a dedicated expansion card for improved wireless connectivity?

1. DIMM slot
2. PCIe slot
3. CPU socket
4. SATA port

Correct Answer: 2

Explanation

A PCI Express slot provides a high-speed expansion interface that can accommodate devices such as wireless network adapters, sound cards, storage controllers, and graphics cards. The exact PCIe lane configuration depends on the device and motherboard design. DIMM slots are intended for system memory, the CPU socket holds the processor, and SATA ports connect compatible storage devices. A wireless adapter installed in a suitable PCIe slot can provide Wi-Fi connectivity when the computer lacks integrated wireless capability. Therefore, a PCIe slot is the appropriate expansion interface.

Question 342

Which storage technology is generally preferred when a technician needs fast boot times and rapid application loading?

1. HDD
2. Optical disc
3. SSD
4. Magnetic tape

Correct Answer: 3

Explanation

Solid-state drives provide significantly faster access times than traditional mechanical hard disk drives because they use flash memory without spinning platters or moving read/write heads. Installing an operating system and applications on an SSD can reduce boot times and improve application responsiveness. NVMe SSDs connected through PCIe can provide even higher performance than SATA-based SSDs when supported by the system. Optical discs and magnetic tape are designed for other storage purposes and generally have much slower access characteristics. Therefore, an SSD is well suited for fast system booting and application loading.

Question 343

Which connector is typically used to connect a SATA storage drive to the motherboard for data communication?

1. SATA
2. HDMI
3. RJ45
4. USB-B

Correct Answer: 1

Explanation

SATA connectors are used to establish data communication between compatible SATA storage devices and the motherboard or storage controller. A SATA data connector is narrower than the separate SATA power connector used to supply electrical power to the drive. SATA interfaces are commonly found on traditional hard drives and 2.5-inch SATA SSDs. HDMI is used for digital audio and video, RJ45-style connectors are commonly used for Ethernet networking, and USB-B is found on certain external peripherals. Therefore, SATA is the appropriate storage data interface.

Question 344

Which component can provide temporary power to a desktop computer during a short electrical outage?

1. Surge protector
2. UPS
3. Power strip
4. Voltage regulator

Correct Answer: 2

Explanation

An uninterruptible power supply, or UPS, contains a battery that can provide temporary electrical power when utility power fails. This gives users time to save work and shut down equipment safely, depending on the UPS capacity and connected load. Many UPS devices also provide surge protection and power conditioning. A standard power strip distributes electricity but does not normally provide battery backup, while a surge protector protects against certain voltage spikes. Therefore, a UPS is the device designed to provide temporary backup power during an outage.

Question 345

Which type of network cable uses pairs of copper wires twisted together to reduce electromagnetic interference?

1. Fiber-optic
2. Coaxial
3. Twisted-pair
4. Serial

Correct Answer: 3

Explanation

Twisted-pair cable consists of pairs of copper conductors twisted together to help reduce electromagnetic interference and signal crosstalk. It is widely used for Ethernet networking, with cable categories such as Cat 5e, Cat 6, and Cat 6a supporting different performance characteristics. Fiber-optic cable transmits data using light, coaxial cable uses a central conductor surrounded by shielding, and serial cables are designed for specific legacy or specialized connections. Therefore, twisted-pair is the cable type described in the question.

Question 346

Which Windows utility can be used to stop an unresponsive application that is consuming system resources?

1. Task Manager
2. Disk Management
3. Device Manager
4. System Configuration

Correct Answer: 1

Explanation

Task Manager allows a technician to view running applications and processes and can be used to terminate an unresponsive application. It also provides information about CPU, memory, disk, network, and other resource utilization. This makes it useful for diagnosing performance problems and applications that have stopped responding. Disk Management handles storage volumes, Device Manager manages hardware and drivers, and System Configuration provides options for controlling startup and system services. Therefore, Task Manager is the appropriate utility for ending a frozen application.

Question 347

Which protocol is commonly used to transfer files securely between computers over an encrypted connection?

1. FTP
2. TFTP
3. SFTP
4. Telnet

Correct Answer: 3

Explanation

SFTP provides secure file-transfer capabilities through an encrypted SSH connection. It protects authentication credentials and file-transfer traffic from interception when properly configured. Traditional FTP does not inherently encrypt its traffic, TFTP is a lightweight transfer protocol with limited functionality and no built-in encryption, and Telnet provides remote terminal access without the security protections expected from SSH. SFTP is therefore commonly selected when a technician needs to transfer files securely between systems over a network. It is particularly useful for administrative and server-management tasks.

Question 348

Which type of memory is normally installed in a laptop rather than a standard desktop DIMM form factor?

1. SO-DIMM
2. PCIe
3. M.2
4. ATX

Correct Answer: 1

Explanation

SO-DIMM, or Small Outline Dual Inline Memory Module, is a compact memory form factor commonly used in laptops and other space-constrained systems. Its smaller physical dimensions allow manufacturers to provide upgradeable memory while conserving internal space. Standard desktop systems commonly use full-size DIMMs instead. PCIe is an expansion interface, M.2 is a compact connector and form factor often used for storage, and ATX is a motherboard and system form-factor standard. Therefore, SO-DIMM is the memory form factor typically associated with laptops.

Question 349

Which component is responsible for permanently storing user documents when the computer is powered off?

1. RAM
2. CPU cache
3. SSD
4. Register

Correct Answer: 3

Explanation

An SSD provides nonvolatile storage, meaning information remains stored when the computer is powered off. User documents, applications, operating-system files, photographs, and other persistent data can be stored on an SSD. RAM and CPU cache are volatile memory technologies used while the system is operating, while processor registers hold very small amounts of data needed for immediate instruction processing. SSDs use flash memory and have no moving mechanical components. Therefore, an SSD provides persistent storage for user documents.

Question 350

Which wireless technology is primarily intended for connecting peripherals such as keyboards, mice, and headsets?

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

Correct Answer: 2

Explanation

Bluetooth is designed for short-range personal-area communication and is widely used for wireless peripherals such as keyboards, mice, speakers, headsets, and game controllers. It generally consumes relatively little power and supports convenient device pairing. GPS is used for location services, NFC is designed for very short-range interactions such as contactless transactions, and cellular technology provides wide-area mobile connectivity. Therefore, Bluetooth is the wireless technology most commonly associated with connecting short-range personal peripherals.

Question 351

Which Windows command can be used to determine the IP address associated with a domain name?

1. nslookup
2. netstat
3. tracert
4. hostname

Correct Answer: 1

Explanation

The nslookup command queries the Domain Name System and can display information about how a domain name resolves to an IP address. It is useful when troubleshooting DNS-related problems, verifying name resolution, and checking responses from specific DNS servers. Netstat displays network connections and listening ports, tracert traces the path toward a destination, and hostname displays the local computer’s name. Therefore, nslookup is the appropriate command for determining the IP address associated with a domain name.

Question 352

Which network protocol is primarily responsible for translating human-readable domain names into IP addresses?

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

Correct Answer: 2

Explanation

The Domain Name System, or DNS, translates human-readable domain names into IP addresses and can also provide other types of name and service information. When a user enters a domain name, a DNS resolver searches for the appropriate record and returns the information needed to locate the destination. DHCP provides network configuration, NTP synchronizes clocks, and SMTP handles email transmission. DNS is essential because users can work with memorable names instead of having to remember numerical IP addresses. Therefore, DNS performs the described function.

Question 353

Which Windows recovery feature can help reverse system changes caused by a recently installed driver or application?

1. Disk Cleanup
2. System Restore
3. Task Scheduler
4. Resource Monitor

Correct Answer: 2

Explanation

System Restore can return certain system files, registry settings, drivers, and application-related configuration to an earlier restore point. It can be useful when a recently installed driver or application causes instability and a suitable restore point exists. System Restore is not a replacement for regular data backups and generally does not function as a complete backup of personal files. Disk Cleanup removes unnecessary data, Task Scheduler manages scheduled operations, and Resource Monitor provides detailed resource information. Therefore, System Restore is appropriate for reversing certain recent system changes.

Question 354

Which network device connects multiple wired Ethernet devices and forwards traffic based on destination MAC addresses?

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

Correct Answer: 3

Explanation

A network switch connects multiple Ethernet devices and forwards frames based on MAC-address information. The switch learns which MAC addresses are associated with individual ports and uses that information to send traffic toward the appropriate destination. A router forwards packets between different IP networks, a modem provides a service-provider connection, and an access point primarily provides wireless connectivity. Switches are therefore commonly used to connect computers, printers, servers, and other wired devices within a local network. The correct device is a switch.

Question 355

Which security measure is designed to prevent unauthorized users from reading data if a storage drive is removed from a computer?

1. Disk encryption
2. Screen saver
3. Password hint
4. File compression

Correct Answer: 1

Explanation

Disk encryption protects stored information by converting readable data into an encrypted form that requires the appropriate key or authentication mechanism for access. This provides protection even if a storage drive is physically removed and connected to another computer. A screen saver does not protect data once a drive is removed, a password hint is not an encryption mechanism, and file compression only changes how data is stored. Therefore, disk encryption is the appropriate security measure for protecting data on a removed storage device.

Question 356

Which authentication factor is represented by a fingerprint scan?

1. Something you know
2. Something you have
3. Somewhere you are
4. Something you are

Correct Answer: 4

Explanation

A fingerprint is a biometric characteristic and therefore represents the authentication category known as something you are. Other biometric examples include facial characteristics, iris patterns, and certain behavioral characteristics. Something you know includes passwords and PINs, while something you have includes physical security keys, smart cards, and authentication tokens. Somewhere you are refers to a location-based factor. Biometric authentication can be combined with another factor to create multifactor authentication. Therefore, a fingerprint represents something you are.

Question 357

Which type of attack attempts to make a service unavailable by overwhelming it with excessive traffic?

1. Phishing
2. DDoS
3. Spyware
4. Shoulder surfing

Correct Answer: 2

Explanation

A distributed denial-of-service, or DDoS, attack attempts to disrupt the availability of a service by sending large volumes of traffic or requests toward a target. The traffic can originate from many compromised systems, making it difficult to block based on a single source. Phishing attempts to deceive users into revealing information or taking unsafe actions, spyware secretly collects information, and shoulder surfing involves observing sensitive information. Therefore, DDoS is the attack designed to overwhelm a service and reduce its availability.

Question 358

Which printer component is responsible for permanently bonding toner to the paper?

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

Correct Answer: 3

Explanation

The fuser is the laser-printer component that uses heat and pressure to permanently bond toner particles to the paper. After the image is formed and toner is transferred to the page, the paper passes through the fuser assembly. The pickup roller feeds paper into the printer, the imaging drum helps form the toner image, and the transfer roller assists in moving toner toward the paper. Therefore, the fuser performs the final bonding process that makes the printed image durable.

Question 359

Which storage configuration provides redundancy by maintaining an identical copy of data on two drives?

1. RAID 0
2. RAID 1
3. JBOD
4. Spanning

Correct Answer: 2

Explanation

RAID 1 provides redundancy by mirroring the same data across two drives. If one drive fails, the remaining drive can continue providing access to the mirrored information, assuming the array is otherwise functioning correctly. RAID 0 stripes data across multiple drives for performance but provides no redundancy. JBOD and spanning configurations do not inherently provide the same mirrored protection. RAID 1 reduces usable capacity because the same data is stored twice, but its primary purpose is data redundancy. Therefore, RAID 1 is the correct configuration.

Question 360

A technician confirms that a faulty network cable caused a connectivity problem. What should be done after replacing the cable?

1. Verify connectivity and document the repair
2. Replace the network adapter immediately
3. Delete the network configuration
4. Disable the firewall permanently

Correct Answer: 1

Explanation

After replacing a confirmed faulty network cable, the technician should verify that connectivity has been restored by testing the affected network function. The technician should also document the identified cause, corrective action, and verification results in the service record. Replacing the network adapter without evidence of a hardware problem is unnecessary, while deleting network configuration or permanently disabling security controls could create additional issues. Verification ensures that the repair actually resolved the reported problem. Therefore, testing connectivity and documenting the repair are the appropriate next steps.
