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

Accepted Answer

An anti-glare screen protector with a matte finish.. An anti-glare screen protector with a matte finish reduces reflections by scattering ambient light through a microscopic textured surface, which improves readability in direct sunlight without increasing the display's inherent brightness. This directly addresses the driver's issue of screen glare outdoors, whereas other options either fail to reduce glare or introduce impracticality for mobile use.

Answer

A high-brightness screen protector that boosts luminance.

Answer

A privacy screen filter to reduce viewing angles.

Answer

A sunshade hood that attaches to the tablet case.

Question 2

A user wants to use a portable SSD with their tablet for video editing. The tablet has a USB-C port that supports USB 3.1 Gen 2. They need to transfer large files quickly and also charge the tablet simultaneously. Which accessory should they use?

Accepted Answer

A USB-C hub with power delivery pass-through. A USB-C hub with power delivery (PD) pass-through is the correct accessory because it allows the tablet to simultaneously charge via the hub's PD input while providing a dedicated USB-C data port for the portable SSD. USB 3.1 Gen 2 supports up to 10 Gbps, which is sufficient for fast video file transfers, and PD pass-through ensures the tablet's battery is replenished during use. Without PD pass-through, a standard hub would split power and data, potentially starving the tablet of charge.

Answer

A USB-C to USB-C cable

Answer

A USB-C to USB-A adapter

Answer

A wireless SSD with Bluetooth 5.0

Question 3

A user wants to use a wired headset with their tablet for voice calls, but the tablet only has a single USB-C port and no 3.5mm jack. The headset has a 3.5mm plug. Which accessory should you recommend?

Accepted Answer

A USB-C to 3.5mm adapter.. A USB-C to 3.5mm adapter converts the digital audio signal from the USB-C port into an analog signal that the wired headset can use. This adapter typically includes a built-in DAC (Digital-to-Analog Converter) to handle the conversion, enabling voice calls through the tablet's USB-C port without requiring additional power or Bluetooth pairing.

Answer

A USB-C hub with multiple ports.

Answer

A Bluetooth audio adapter for the headset.

Answer

A 3.5mm Y-splitter cable.

Question 4

A user is setting up a new tablet and wants to share its internet connection with a laptop that has no cellular capability. The tablet has a cellular data plan. Which configuration should the user enable on the tablet?

Accepted Answer

Enable Wi-Fi hotspot.. Enabling a Wi-Fi hotspot on the tablet creates a local wireless network that the laptop can connect to, sharing the tablet's cellular data connection. This is the standard method for tethering when the client device (laptop) lacks cellular capability but has Wi-Fi. Bluetooth pairing (option A) can also share internet, but it is slower and not the primary method for a laptop that expects a Wi-Fi connection.

Answer

Enable Bluetooth pairing only.

Answer

Enable airplane mode.

Answer

Enable NFC.

Question 5

A technician is configuring a remote desktop solution for a user who needs to access their Windows workstation from home. Which port must be forwarded on the router for RDP (Remote Desktop Protocol)?

Accepted Answer

3389. Remote Desktop Protocol (RDP) uses TCP port 3389 by default to establish a graphical interface connection to a Windows workstation. Forwarding this port on the home router allows the technician to route incoming RDP traffic from the internet to the specific internal IP address of the target Windows machine, enabling remote access.

Question 6

A desktop PC fails to power on. The technician measures the voltage on the 24-pin motherboard connector and finds that the purple wire (5VSB) reads 4.9V, but the green wire (PS_ON) reads 0V when the power button is pressed. What does this indicate?

Accepted Answer

The power supply is faulty and needs replacement.. A desktop PC fails to power on. Measurements: 5VSB is present (4.9V is within tolerance), indicating the power supply is receiving AC power and its standby circuitry is working. When the power button is pressed, PS_ON is pulled low (0V) by the motherboard, which is the correct signal to request the PSU to turn on. Since the PSU does not start (fans don't spin, no other outputs), the fault lies within the power supply itself. A faulty PSU may have a failed main switching circuit or other internal defect preventing it from responding to the PS_ON signal. Therefore, the power supply should be replaced. Option B is incorrect because a low PS_ON indicates the motherboard is functioning correctly in this regard.

Answer

The motherboard is not sending the PS_ON signal, likely due to a fault.

Answer

The power supply's +12V rail is shorted, causing overcurrent protection.

Answer

The front panel power switch is stuck in the closed position.

Question 7

A technician is setting up a network printer that supports both LPD (Line Printer Daemon) and IPP (Internet Printing Protocol). The printer must be accessible from Windows and Linux clients. Which port should be opened for IPP?

Accepted Answer

631. IPP (Internet Printing Protocol) uses TCP port 631 by default, as defined in RFC 2911. Since the printer must be accessible from both Windows and Linux clients, opening port 631 allows IPP-based printing, which is natively supported by both operating systems.

Question 8

A small business has a single access point that supports both 2.4 GHz and 5 GHz. Employees report that their smartphones connect to the 2.4 GHz band, causing slow internet speeds. Which configuration change should the technician make to prioritize 5 GHz for capable devices?

Accepted Answer

Enable band steering on the access point.. Band steering (also called client steering) is the correct solution because it actively encourages dual-band clients to connect to the less congested 5 GHz band by manipulating probe responses and beacon timing, without disabling the 2.4 GHz radio for legacy devices. This directly addresses the problem of smartphones preferring the 2.4 GHz band due to its stronger signal, while still allowing older 2.4 GHz-only devices to connect.

Answer

Disable the 2.4 GHz radio completely.

Answer

Set the 2.4 GHz channel to a non-overlapping channel like 1, 6, or 11.

Answer

Increase the transmit power of the 5 GHz radio.

Question 9

A network administrator is setting up a new branch office. The branch router must automatically obtain a public IP address from the ISP, and internal devices must receive private IP addresses from the router. Which combination of network services should be configured on the router?

Accepted Answer

DHCP client and DHCP server. The branch router needs to obtain a public IP address automatically from the ISP, which requires it to act as a DHCP client on its WAN interface. At the same time, internal devices need private IP addresses, so the router must also act as a DHCP server on its LAN interface, leasing addresses from a private range. Option B correctly combines both roles: DHCP client on the WAN side and DHCP server on the LAN side.

Answer

DHCP client and DNS server

Answer

DHCP server and NAT

Answer

DNS server and NAT

Question 10

A user reports that they cannot access the internet, but they can ping other devices on the local network. The technician checks the IP configuration and sees: IP: 192.168.1.25, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.2.1. What is the issue?

Accepted Answer

The default gateway is on a different subnet.. The default gateway 192.168.2.1 is not on the same subnet as the host IP 192.168.1.25 with subnet mask 255.255.255.0. For a /24 network, the host's subnet is 192.168.1.0/24, while the gateway belongs to 192.168.2.0/24. The host will ARP for the gateway but never receive a reply because the gateway is on a different Layer 2 broadcast domain, making internet access impossible despite local connectivity.

Answer

The subnet mask is incorrect.

Answer

The IP address is a broadcast address.

Answer

The DNS server is misconfigured.

Question 11

A technician is troubleshooting a customer's home network where the desktop PC is wired to the router, but the wireless printer intermittently disappears from the network. The printer is connected via Wi-Fi to the same router. After checking, the technician finds that the printer's IP address is in the 169.254.x.x range. Which network type is the printer attempting to use, and what does this indicate?

Accepted Answer

WLAN with DHCP failure; the printer has self-assigned an APIPA address.. The 169.254.x.x IP address range is reserved for Automatic Private IP Addressing (APIPA), which a device assigns to itself when it fails to obtain an IP address from a DHCP server. Since the printer is connected via Wi-Fi to the same router, this indicates a DHCP failure on the WLAN, causing the printer to use a self-assigned APIPA address and intermittently disappear from the network.

Answer

Peer-to-peer network; the printer is sharing directly with the PC.

Answer

PAN network; the printer is using Bluetooth.

Answer

Ad hoc network; the printer is connecting directly to the PC.

Question 12

A small business owner wants to connect five computers in a single office so they can share files and a printer without purchasing a server. Which network type should be configured?

Accepted Answer

Peer-to-peer network. A peer-to-peer network (B) is the correct choice because it allows five computers to share files and a printer directly without a dedicated server. Each computer acts as both a client and a server, making it ideal for small offices with fewer than 10 devices where centralized management is unnecessary.

Answer

Client-server network

Answer

Wide area network (WAN)

Answer

Metropolitan area network (MAN)

Question 13

A user complains that their wireless mouse and keyboard stop working when they move more than 10 feet away from the computer. The devices use a USB dongle. Which network type is being used for these peripherals?

Accepted Answer

Personal Area Network (PAN). Personal Area Network (PAN), because wireless mice and keyboards that connect via a USB dongle typically use Bluetooth or a proprietary 2.4 GHz RF protocol, which creates a short-range PAN. The 10-foot range limitation is characteristic of PAN technologies, which are designed for personal device connectivity within a few meters, not for broader network coverage.

Answer

Local Area Network (LAN)

Answer

Wide Area Network (WAN)

Answer

Metropolitan Area Network (MAN)

Question 14

A company is moving to a new building that has no existing internet infrastructure. They need the highest possible download speeds with low latency for cloud applications. Which connection type should they choose?

Accepted Answer

Fiber optic. Fiber optic uses light pulses transmitted through glass or plastic strands, offering symmetrical gigabit speeds (e.g., 1 Gbps or higher) with extremely low latency (often <5 ms). This makes it ideal for cloud applications requiring high download speeds and real-time responsiveness, unlike older copper-based or wireless technologies.

Answer

DSL

Answer

Cable

Answer

Fixed wireless

Question 15

After deploying a new 802.11ac access point, users report that some devices can connect but others cannot, even though they are in the same room. All devices support 5 GHz. What is the most likely cause?

Accepted Answer

The access point is overloaded with clients.. The scenario describes that some devices can connect while others cannot, even though all devices support 5 GHz. This points to a resource limitation on the access point rather than a radio band issue. If the access point is overloaded with clients, it may reach its maximum association limit, rejecting new connections while existing ones remain active. This explains why some devices are connected and others are not. Option B is incorrect because disabling 2.4 GHz radios would not affect devices that support 5 GHz. Option A is not a problem, as non-overlapping channels are beneficial. Option C would affect all devices uniformly.

Answer

The access point is using a non-overlapping channel.

Answer

The access point has 2.4 GHz radios disabled.

Answer

The devices have incorrect SSID credentials.
