Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

A network-attached storage (NAS) device. A NAS device is designed for centralized file sharing on a local network, supports permissions, and works with both Windows and macOS clients. It avoids recurring cloud fees and is more affordable and manageable than a SAN. The other options either do not provide network-wide shared access, are too complex, or violate the no-subscription requirement.

Answer

A direct-attached storage (DAS) enclosure

Answer

A storage area network (SAN)

Answer

A cloud storage subscription

Question 2

A technician is configuring a laptop for a user who frequently travels and needs to connect to both wired and wireless networks. The laptop has an RJ45 port and supports Wi-Fi 6. Which statement accurately describes the role of the network interface card (NIC) in this scenario?

Accepted Answer

The NIC provides the physical and data link layer connection for both wired and wireless communication.. The NIC is responsible for the physical and data link layer functions, enabling the laptop to communicate over Ethernet and Wi-Fi. Modems convert digital to analog, DHCP servers assign IP addresses, and routers route packets between networks, so those roles belong to other devices.

Answer

The NIC assigns IP addresses to other devices on the network.

Answer

The NIC converts digital signals to analog for transmission over the internet.

Answer

The NIC routes packets between different networks.

Question 3

A technician is troubleshooting a desktop computer that powers on but does not display any video. The monitor works when connected to another computer. Which TWO of the following are the most likely causes to check first? (Choose two.)

Accepted Answer

The video cable is loose or connected to the wrong port. When a computer powers on but shows no video and the monitor is known good, the first things to verify are the video cable connection and input selection, followed by internal components that can halt POST such as improperly seated RAM. Printer drivers, keyboard layout, and a switched-off surge protector do not match the symptom of powering on without display.

Answer

The printer driver is outdated

Answer

The keyboard layout is set incorrectly

Answer

The surge protector is switched off

Question 4

A technician is connecting a desktop PC directly to a cable modem to provide internet access. The PC needs to receive a public IP address automatically from the ISP. Which protocol should the technician ensure is enabled on the PC's network adapter?

Accepted Answer

DHCP. The PC must obtain a public address from the ISP without manual entry, which is the role of DHCP. The ISP's DHCP server leases the address along with gateway and DNS details. DNS, SMTP, and SNMP serve naming, email, and management functions respectively and cannot assign an address to the adapter.

Answer

DNS

Answer

SNMP

Answer

SMTP

Question 5

A user reports that their desktop computer will not power on at all. No lights appear, and no fans spin. The power cable is securely connected to the wall outlet and the power supply. Which component should the technician check first?

Accepted Answer

The power supply unit. A completely unresponsive computer with no lights or fan activity points to a power delivery problem, making the power supply unit the first component to check. RAM, hard drive, and CPU cooler issues would typically allow some signs of power or produce specific errors.

Answer

The hard drive

Answer

The CPU cooler

Answer

The RAM modules

Question 6

A technician needs to connect a new desktop computer to a wired network in an office where the wall jack is active and the network uses DHCP. The computer has an integrated RJ45 port. Which of the following should the technician do to enable network connectivity?

Accepted Answer

Connect an Ethernet cable from the wall jack to the computer's RJ45 port. With an active wall jack, an integrated RJ45 port, and DHCP in place, the only required action is to connect a standard Ethernet cable between the jack and the computer. DHCP will handle IP configuration automatically. Wireless, static addressing, and Internet Connection Sharing are either unnecessary or incorrect for this wired scenario.

Answer

Assign a static IP address in the same subnet as the gateway

Answer

Install a wireless network adapter and configure the SSID

Answer

Enable Internet Connection Sharing on the computer

Question 7

A small business owner wants to print multi-part carbon-copy invoices on continuous form paper in a warehouse environment where dust is common. Which printer type is most appropriate?

Accepted Answer

Dot matrix. Impact printing is the only method that physically transfers ink through multiple paper layers to create carbon copies. Dot matrix printers are designed for continuous form paper and tolerate dusty industrial environments, making them the standard choice for multi-part invoices. Inkjet, laser, and thermal technologies all print on a single surface and cannot produce duplicate copies on multi-part forms.

Answer

Inkjet

Answer

Laser

Answer

Thermal

Question 8

A user reports that their desktop computer powers on, the fans spin, but the monitor shows no signal and there are no beep codes. A technician notices the monitor's cable is connected to a port on the motherboard, but the computer has a dedicated graphics card installed. Which of the following is the MOST likely explanation?

Accepted Answer

The monitor cable is connected to the motherboard's integrated video port instead of the discrete graphics card's port.. The system powers on and fans spin, indicating power and basic operation, but no video appears because the display cable is attached to the motherboard's video port. When a dedicated graphics card is present, integrated video is often disabled, so the motherboard port produces no signal. Connecting the monitor to the graphics card's output resolves the issue.

Answer

The power supply unit is failing and cannot provide enough wattage to the graphics card.

Answer

The monitor is defective and needs to be replaced.

Answer

The RAM is not seated properly, preventing the system from completing POST.

Question 9

A small design studio needs a central device so five wired workstations and two networked printers can exchange data with each other on the same local network. The studio does not need any routing between separate networks. Which device is the best choice?

Accepted Answer

A switch. A switch is the appropriate central device for a single local network with multiple wired endpoints. It forwards frames between connected devices and provides enough ports for the workstations and printers. A router, firewall, or access point does not fulfill the role of aggregating several wired devices on one segment.

Answer

A wireless access point

Answer

A router

Answer

A firewall

Question 10

A technician is assembling a desktop PC for a video editor. The editor frequently transfers large project files to and from external drives and wants the fastest currently available consumer interface. Which interface should the technician prioritize on the motherboard?

Accepted Answer

Thunderbolt 4. The editor needs the fastest consumer external interface for large project files, and Thunderbolt 4 delivers up to 40 Gbps over USB-C. USB 2.0, eSATA, and FireWire 800 are all far slower and largely legacy, so they cannot meet the performance requirement. Thunderbolt 4 is the only listed option that provides current top-tier throughput.

Answer

FireWire 800

Answer

eSATA

Answer

USB 2.0

Question 11

A technician is setting up a new laptop for a traveling salesperson. The laptop must have a built-in cellular modem so the user can access the internet without relying on Wi-Fi hotspots or tethering to a phone. Which internal expansion slot is specifically designed to accept a cellular modem module in a modern laptop?

Accepted Answer

M.2 slot. A cellular modem module in a laptop connects through an M.2 slot keyed for WWAN, typically using PCIe or USB lanes. This slot is designed for the small 3042/3052 module form factor and works with the pre-installed antenna cables found in business laptops. Other listed slots serve memory, storage, or desktop expansion roles and cannot accept or electrically support a WWAN module.

Answer

SO-DIMM slot

Answer

SATA data connector

Answer

PCIe x16 slot

Question 12

A technician is troubleshooting a desktop PC that powers on but produces no video and emits a repeating beep pattern. The motherboard has an integrated speaker and no POST card is available. Which component should the technician check first?

Accepted Answer

RAM module. POST beep codes are diagnostic signals generated when the BIOS detects a hardware failure before video initialization. A repeating pattern most often maps to a memory initialization failure, so reseating or swapping RAM is the logical first action. Power, storage, and CMOS issues produce different symptoms such as no power, boot device errors, or configuration resets rather than repeating beeps.

Answer

Hard disk drive

Answer

Power supply unit

Answer

CMOS battery

Question 13

A small business wants to connect its office computers to a network that provides centralized authentication, file sharing, and printer sharing without relying on a cloud service. The owner wants to minimize recurring costs and keep data on-site. Which of the following should the technician implement?

Accepted Answer

A client-server network with a dedicated server running directory services and shared folders.. A client-server network with an on-premises server delivers centralized authentication, file sharing, and printer sharing while avoiding cloud subscriptions. Directory services on the server allow unified account management and access control. This setup meets the small business's needs for local data storage, centralized administration, and low recurring cost.

Answer

A workgroup where each computer manages its own user accounts and shared resources.

Answer

A peer-to-peer network using each workstation as both client and server for shared resources.

Answer

A virtual private network (VPN) connecting all computers to a remote cloud directory.

Question 14

A user reports that a laptop battery no longer holds a charge and the laptop shuts down immediately when unplugged. The laptop is several years old and the user wants to keep using it. Which of the following is the most appropriate replacement component?

Accepted Answer

A new laptop battery compatible with the model. A battery that no longer holds a charge and causes immediate shutdown when unplugged is failing and should be replaced with a compatible unit. Power adapters, motherboards, and RAM do not address battery capacity loss. Replacing the battery is the correct, targeted repair that restores portable use.

Answer

A higher-wattage power adapter

Answer

An additional RAM module

Answer

A replacement motherboard

Question 15

A small business has a single server that hosts a customer database. The owner wants to ensure the database remains available if the server's primary power supply fails. Which component should the technician install to meet this need?

Accepted Answer

A redundant power supply. The owner needs the server to stay online if its power supply fails, which is exactly what a redundant power supply provides. Extra CPU, RAM, or storage improves performance or capacity but leaves the server vulnerable to a single power failure. Only a second power supply removes that single point of failure.

Answer

A larger hard drive

Answer

Additional RAM

Answer

A second CPU
