Question 181

Which component provides electrical power to the internal components of a desktop computer by converting AC power into usable DC voltages?

1. PSU
2. UPS
3. Heat sink
4. Voltage regulator

Correct Answer: 1

Explanation

The power supply unit, or PSU, converts incoming AC electrical power into the DC voltages required by components such as the motherboard, processor, storage drives, and expansion cards. A PSU also distributes power through different connectors and maintains appropriate electrical output for the connected hardware. A UPS provides temporary battery-backed power, while a heat sink removes heat and a voltage regulator manages voltage for specific circuits. Therefore, the PSU is the primary component responsible for converting and distributing electrical power inside a desktop computer.

Question 182

Which connector is commonly used to provide power to a SATA internal storage drive?

1. 4-pin Molex
2. SATA power connector
3. RJ45
4. PCIe x16

Correct Answer: 2

Explanation

A SATA power connector supplies electrical power to compatible SATA storage devices such as hard disk drives and SATA solid-state drives. SATA drives normally use separate connectors for power and data. The SATA data connector transfers information between the drive and motherboard, while the SATA power connector receives electrical power from the PSU. Molex connectors were common in older systems, RJ45 is used for Ethernet networking, and PCIe x16 is an expansion slot. Therefore, the SATA power connector is appropriate for powering a SATA storage drive.

Question 183

A user reports that a laptop battery drains unusually quickly after several applications are left running in the background. What should the technician investigate first?

1. CPU and application resource usage
2. Printer toner level
3. Ethernet cable category
4. Monitor mounting bracket

Correct Answer: 1

Explanation

Applications running in the background can consume CPU resources, memory, storage activity, network connectivity, and other power-consuming resources. A technician should inspect active applications and system resource usage to identify processes that may be contributing to excessive battery consumption. Windows Task Manager and comparable operating-system utilities can help identify resource-intensive processes. Printer toner, Ethernet cable category, and monitor mounting hardware do not normally affect laptop battery consumption. Investigating resource usage can help determine whether software activity is causing the abnormal battery drain.

Question 184

Which display interface commonly supports digital video and audio and is frequently found on modern monitors and computers?

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

Correct Answer: 3

Explanation

DisplayPort is a digital display interface commonly used to connect computers to monitors and other display equipment. Depending on the implementation and version, DisplayPort can carry high-resolution video and digital audio through a single connection. VGA is an older analog video interface, PS/2 was commonly used for legacy keyboards and mice, and RJ11 is associated with telephone connections. DisplayPort may also support features such as daisy chaining compatible displays. Therefore, DisplayPort is the interface that best matches the described requirements.

Question 185

Which storage interface is designed specifically for communication with modern solid-state drives using PCI Express?

1. IDE
2. NVMe
3. PATA
4. SCSI

Correct Answer: 2

Explanation

NVMe, or Non-Volatile Memory Express, is a storage protocol designed to take advantage of the high bandwidth and low latency available through PCI Express. It is commonly used with modern solid-state drives, particularly M.2 NVMe SSDs. IDE and PATA are older storage technologies, while SCSI is an older family of storage and peripheral interfaces that has largely been replaced in many modern systems. NVMe allows solid-state storage to communicate efficiently with the system and generally provides substantially higher performance than older storage interfaces.

Question 186

Which device can provide a shared keyboard, video, and mouse connection for controlling multiple computers?

1. KVM switch
2. USB hub
3. Network switch
4. Docking station

Correct Answer: 1

Explanation

A KVM switch, meaning Keyboard, Video, and Mouse switch, allows a technician or user to control multiple computers using a shared keyboard, monitor, and mouse setup. KVM switches are useful in server rooms, testing environments, and workstations where several computers need to be accessed from one console. A USB hub expands USB connectivity, a network switch connects devices on a network, and a docking station expands laptop connectivity. Therefore, the KVM switch is specifically designed for sharing keyboard, video, and mouse control.

Question 187

Which wireless security protocol is newer than WPA2 and is designed to provide stronger protections for modern wireless networks?

1. WEP
2. WPA
3. WPA3
4. TKIP

Correct Answer: 3

Explanation

WPA3 is a newer wireless security standard designed to improve security compared with earlier standards such as WPA and WPA2. It provides stronger protections for authentication and wireless communication and includes improvements intended to make certain attacks more difficult. WEP is an outdated wireless security mechanism and should not be relied upon for modern security. WPA is an older standard, while TKIP is an encryption protocol associated with older WPA implementations rather than a complete modern wireless security standard. Therefore, WPA3 is the correct choice.

Question 188

Which network device regenerates or strengthens a signal so it can travel a greater physical distance?

1. Router
2. Repeater
3. Firewall
4. DHCP server

Correct Answer: 2

Explanation

A repeater receives a network signal and regenerates or retransmits it to extend the usable transmission distance. Repeaters can be useful when the signal would otherwise become too weak over a longer physical cable or wireless path. A router forwards traffic between networks, a firewall applies security rules to network traffic, and a DHCP server provides network configuration information to clients. Modern networks may use specialized access points, switches, or other infrastructure instead of simple repeaters, but the fundamental signal-extension function belongs to the repeater.

Question 189

Which IPv4 address range is commonly associated with APIPA when a Windows computer cannot obtain an address from DHCP?

1. 10.0.0.0/8
2. 172.16.0.0/12
3. 169.254.0.0/16
4. 192.168.0.0/16

Correct Answer: 3

Explanation

Automatic Private IP Addressing, or APIPA, commonly assigns an IPv4 address from the 169.254.0.0/16 range when a compatible system cannot obtain an address from a DHCP server. An APIPA address allows limited local communication in some circumstances but generally does not provide normal routed internet connectivity. The 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 ranges are private IPv4 address spaces commonly used for manually or dynamically configured local networks. Therefore, 169.254.0.0/16 identifies the APIPA range.

Question 190

Which protocol is commonly used to securely transfer files through an SSH connection?

1. SFTP
2. HTTP
3. SMTP
4. Telnet

Correct Answer: 1

Explanation

SFTP, or SSH File Transfer Protocol, provides secure file transfer through an SSH-based connection. It encrypts authentication information and transferred data, making it appropriate for securely moving files between systems. HTTP is primarily used for web communication, SMTP is used for email transmission, and Telnet provides remote terminal communication without modern encryption protections. SFTP should not be confused with FTPS, which uses FTP with TLS protection. Therefore, SFTP is the protocol that provides secure file transfer through SSH.

Question 191

Which component on a motherboard is primarily responsible for retaining firmware configuration settings when the system is powered off?

1. CPU
2. CMOS battery
3. RAM module
4. GPU

Correct Answer: 2

Explanation

The CMOS battery traditionally provides power that allows certain motherboard configuration information to remain available when the computer is turned off. A weak or depleted CMOS battery can result in lost firmware settings, incorrect system time, or startup configuration messages on some systems. The CPU performs processing, RAM provides temporary working memory, and the GPU handles graphics processing. Modern systems may use flash-based implementations for configuration storage, but the CMOS battery remains an important component associated with maintaining motherboard settings and real-time clock operation.

Question 192

Which printer type is generally best suited for producing high volumes of fast monochrome documents?

1. Inkjet
2. Laser
3. Dot matrix
4. Thermal receipt printer

Correct Answer: 2

Explanation

Laser printers are well suited to high-volume document printing because they can produce pages quickly and use toner rather than liquid ink. They are commonly deployed in offices where large quantities of text-based documents must be produced efficiently. Inkjet printers are often useful for color and photo printing, dot-matrix printers are useful for certain multipart forms, and thermal receipt printers are designed for specialized heat-sensitive media. Therefore, a laser printer is generally appropriate for high-volume monochrome office printing.

Question 193

Which type of connector was commonly used for analog video output on older computer systems?

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

Correct Answer: 1

Explanation

VGA, or Video Graphics Array, is an older analog video interface commonly found on legacy computers and monitors. It typically uses a 15-pin connector and carries video information without digital audio. HDMI, DisplayPort, and USB-C can support digital video through appropriate implementations, with some also supporting digital audio. Although VGA remains present on some older equipment, modern systems increasingly use digital display interfaces. Therefore, VGA is the connector associated with traditional analog computer video output.

Question 194

A technician needs to determine whether a computer can reach a known IP address across the network. Which utility is most appropriate for a basic connectivity test?

1. nslookup
2. ping
3. format
4. sfc

Correct Answer: 2

Explanation

The ping utility sends ICMP echo requests to a specified destination and reports whether responses are received. This makes it a common first-line tool for testing basic network reachability. If a computer cannot successfully ping a known reachable address, the technician can investigate local configuration, routing, firewalls, connectivity, or the remote host. nslookup focuses on DNS queries, format prepares storage media, and sfc checks Windows system files. Therefore, ping is the most appropriate utility for a basic IP connectivity test.

Question 195

Which cloud service model provides users with complete software applications through a provider’s infrastructure?

1. IaaS
2. PaaS
3. SaaS
4. Colocation

Correct Answer: 3

Explanation

Software as a Service, or SaaS, provides complete software applications that users access through a provider’s infrastructure. The provider generally manages the underlying hardware, operating system, application platform, and much of the software maintenance. Users typically focus on using the application rather than managing its infrastructure. IaaS provides virtualized infrastructure resources, PaaS provides a managed platform for application development and deployment, and colocation involves housing customer-owned equipment in a facility. Therefore, SaaS is the cloud service model described.

Question 196

Which type of backup contains only data changed since the previous backup of any type?

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

Correct Answer: 3

Explanation

An incremental backup copies data that has changed since the most recent backup, whether that previous backup was full or incremental. This generally makes each incremental backup smaller and faster than a full backup, but restoring data may require the original full backup and each relevant incremental backup in sequence. A differential backup captures changes since the last full backup, while a full backup copies all selected data. A mirror backup maintains a direct copy of selected data. Therefore, incremental backup matches the described behavior.

Question 197

Which Windows utility provides detailed records of application, system, and security events that can assist with troubleshooting?

1. Event Viewer
2. Disk Management
3. Registry Editor
4. Character Map

Correct Answer: 1

Explanation

Event Viewer provides access to Windows event logs containing records generated by applications, system components, security mechanisms, and other services. Technicians can examine timestamps, event sources, severity levels, and event descriptions to identify patterns associated with failures or unusual behavior. Disk Management manages storage partitions and volumes, Registry Editor modifies configuration information stored in the Windows Registry, and Character Map provides access to special characters. Therefore, Event Viewer is the appropriate tool for reviewing detailed Windows event records during troubleshooting.

Question 198

Which security practice reduces the potential damage if an attacker compromises a standard user account?

1. Giving the account permanent administrator privileges
2. Applying least privilege
3. Disabling all authentication
4. Sharing one administrator password

Correct Answer: 2

Explanation

The principle of least privilege limits an account’s permissions to those necessary for its legitimate tasks. If an attacker compromises a standard account, restricting its permissions can reduce the systems, files, and configuration areas that the attacker can access or modify. Granting permanent administrator privileges increases the potential impact of an account compromise. Disabling authentication removes an important security control, while sharing administrator passwords creates accountability and security problems. Therefore, applying least privilege is an important method of limiting the impact of compromised accounts.

Question 199

Which physical security measure can help protect a laptop from theft when it is used in a public or shared environment?

1. Kensington-style security cable
2. HDMI adapter
3. USB hub
4. Ethernet crossover cable

Correct Answer: 1

Explanation

A Kensington-style security cable can physically secure a compatible laptop to a fixed object, helping deter opportunistic theft in offices, classrooms, libraries, and other shared environments. The cable typically attaches to a dedicated security slot on the laptop and is then secured to an immovable structure. An HDMI adapter provides display connectivity, a USB hub expands peripheral connections, and an Ethernet crossover cable is used for certain direct network connections. Physical security measures complement logical controls such as passwords and encryption.

Question 200

A technician replaces a defective component and confirms that the original problem is resolved. Which final action is most appropriate?

1. Immediately remove all replacement hardware
2. Document the repair and communicate the outcome
3. Delete the user’s profile
4. Disable system security updates

Correct Answer: 2

Explanation

After a successful repair, the technician should document the problem, diagnostic steps, component replaced, actions performed, verification results, and any relevant recommendations. The outcome should also be communicated to the user or recorded through the organization’s support process. Proper documentation creates a useful history for future incidents and helps maintain accurate asset and service records. Removing functioning replacement hardware, deleting user profiles, or disabling security updates would be inappropriate and could introduce new problems. Therefore, documenting and communicating the completed repair is the appropriate final action.
