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

Accepted Answer

Label both ends of each cable with a unique identifier.. Labeling both ends of each cable with a unique identifier is a best practice for cable management that directly reduces troubleshooting time. When a cable fault occurs or a move/add/change is needed, technicians can quickly trace the cable from the patch panel to the workstation jack without tone-and-probe testing, minimizing downtime. This practice aligns with TIA/EIA-606-A labeling standards for administration of telecommunications infrastructure.

Answer

Use crossover cables for all workstation connections.

Answer

Run cables parallel to electrical wiring to save space.

Answer

Use flat ribbon cables for all long runs.

Question 2

A technician is repairing a tablet that has a cracked digitizer. The LCD panel is intact and displays correctly. After replacing the digitizer, the touch input is unresponsive. What is the most likely oversight?

Accepted Answer

The digitizer flex cable is not fully seated in the connector.. The digitizer flex cable must be fully seated and locked into its connector on the tablet's mainboard to establish electrical continuity for touch signals. If the cable is loose or not properly inserted, the touch controller cannot communicate with the digitizer, resulting in a completely unresponsive touch input despite the LCD display functioning correctly.

Answer

The digitizer is not compatible with the tablet model.

Answer

The LCD panel was damaged during the repair.

Answer

The tablet's touch controller needs to be calibrated.

Question 3

A technician is deploying tablets for use in a warehouse where workers wear gloves. The tablets need to be used for scanning barcodes and entering data. Which accessory is most critical for this environment?

Accepted Answer

A rugged case.. In a warehouse environment where workers wear gloves, the most critical accessory is a rugged case because it protects the tablet from drops, dust, and moisture common in industrial settings. While gloves prevent capacitive touchscreen use, a rugged case does not solve input issues but ensures device survival; however, the question asks for the most critical accessory for the environment, and without rugged protection, the tablet would fail quickly. The correct answer is C because it directly addresses the physical hazards of the warehouse, which are more fundamental than input method challenges.

Answer

A screen protector.

Answer

A Bluetooth keyboard.

Answer

A capacitive stylus.

Question 4

A field technician frequently uses a ruggedized tablet outdoors for data collection. They complain that the screen is hard to read in direct sunlight. Which accessory would best improve screen visibility without adding significant bulk?

Accepted Answer

An anti-glare screen protector. An anti-glare screen protector uses a matte finish with microscopic ridges that diffuse reflected light, reducing glare and improving contrast in bright environments. This directly addresses the technician's issue of poor readability in direct sunlight without adding significant bulk to the ruggedized tablet.

Answer

A privacy filter

Answer

A portable external monitor

Answer

An external battery pack

Question 5

A technician is configuring a new wireless router for a home office. The customer wants to ensure that guests can access the internet but cannot see other devices on the main network. Which feature should the technician enable on the router?

Accepted Answer

Guest network. Enabling a guest network creates a separate SSID and VLAN (or subnet) that isolates guest traffic from the main LAN. This prevents guests from accessing local devices (e.g., printers, file shares) while still providing internet access through the router's NAT. The isolation is typically achieved via client isolation or AP isolation settings, ensuring Layer 2 separation between the guest and main networks.

Answer

MAC address filtering

Answer

Port forwarding

Answer

WPS (Wi-Fi Protected Setup)

Question 6

A network administrator is configuring a new firewall to allow remote employees to securely access internal resources. The requirement is to encrypt all traffic between the remote client and the internal network. Which protocol should be used?

Accepted Answer

IPsec. IPsec is the correct choice because it provides end-to-end encryption at the network layer (Layer 3), securing all IP traffic between a remote client and an internal network. It operates in tunnel mode to encapsulate the entire original IP packet, ensuring confidentiality, integrity, and authentication for remote access VPNs. SSL/TLS operates at the transport layer and is typically used for securing individual application sessions (e.g., HTTPS), not for encrypting all traffic from a remote client to an entire internal network.

Answer

SSL/TLS

Answer

L2TP

Answer

HTTP

Question 7

A small business is moving to a new office that already has a fiber-optic termination point installed. They need the fastest symmetrical speeds for cloud-based applications. Which internet connection type should they choose?

Accepted Answer

Fiber-optic. Fiber-optic internet provides symmetrical speeds (equal upload and download) essential for cloud-based applications that require fast data transfer in both directions. Unlike other connection types, fiber uses light signals through glass strands, offering low latency and high bandwidth that scale to meet business needs without the distance limitations of copper-based technologies.

Answer

DSL

Answer

Cable broadband

Answer

Satellite

Question 8

A technician is configuring a new SOHO router for a client who has a DSL internet connection. What type of cable will the technician use to connect the router to the wall jack?

Accepted Answer

Telephone cable (RJ-11). DSL (Digital Subscriber Line) transmits data over standard copper telephone lines using frequencies above the voice band. The wall jack for DSL is a standard RJ-11 phone jack, so the technician must use a telephone cable with RJ-11 connectors to connect the router's DSL port to the wall jack.

Answer

Coaxial cable (RG-6)

Answer

Fiber optic cable

Answer

Ethernet cable (RJ-45)

Question 9

A customer complains that their desktop computer loses network connectivity every time a large file is transferred. The issue does not occur during normal web browsing. What hardware component is most likely at fault?

Accepted Answer

The network interface card (NIC) is failing.. The network interface card (NIC) is most likely at fault because it handles the transmission and reception of network data. During large file transfers, the NIC operates at high throughput, which can expose intermittent failures such as overheating, faulty components, or driver issues. Normal web browsing uses less bandwidth and may not trigger the problem. A failing NIC can cause connectivity drops under heavy load.

Answer

The CPU is overheating.

Answer

The power supply unit is underpowered.

Answer

The Ethernet cable is too long.

Question 10

A user reports that their external monitor connected to a laptop via HDMI flickers intermittently. The laptop's built-in display works fine. You have tried a different HDMI cable and a different monitor, but the flickering persists. What should you check next?

Accepted Answer

Inspect the HDMI port on the laptop for physical damage or debris.. The issue is isolated to the external monitor connection, and swapping cable and monitor didn't help. This points to a defective or loose HDMI port on the laptop, which can cause intermittent signal loss. Testing with a known-good display on a different port or device confirms the port as the root cause.

Answer

Update the graphics driver to the latest version.

Answer

Replace the video cable with a DisplayPort cable.

Answer

Disable the laptop's built-in display to force the external monitor as primary.

Question 11

A user wants to mirror their Android smartphone's screen to a smart TV that does not support Miracast. The TV has HDMI and USB ports. Which device should the technician recommend?

Accepted Answer

A Chromecast device. A Chromecast device connects to the TV via HDMI and uses Wi-Fi Direct (not Miracast) to receive a screen mirror from an Android smartphone. Since the TV lacks Miracast support but has an HDMI port, Chromecast provides the necessary hardware and protocol (Google Cast) to enable wireless display mirroring.

Answer

A USB-C to HDMI cable

Answer

A Bluetooth transmitter

Answer

An NFC tag

Question 12

A user reports that their computer intermittently freezes for a few seconds during normal use. The technician checks Event Viewer and finds 'WHEA-Logger' errors related to the CPU. What is the most likely cause?

Accepted Answer

Unstable CPU overclock or insufficient voltage. WHEA-Logger errors (Windows Hardware Error Architecture) related to the CPU typically indicate hardware-level errors such as machine check exceptions, cache errors, or thermal issues. Intermittent freezes combined with CPU-related WHEA errors most commonly point to an unstable CPU overclock or insufficient voltage, which causes the CPU to throw correctable or uncorrectable errors under load.

Answer

Outdated graphics driver

Answer

CPU overheating

Answer

Faulty hard drive

Question 13

A small office is upgrading from 100Base-TX to 1000Base-T. The existing cabling is Cat5e, runs are under 50 meters, and terminations are T568B. After the upgrade, some workstations intermittently lose connectivity. What is the most likely issue?

Accepted Answer

The terminations are not fully seated or have poor contact on some pairs.. Cat5e supports 1000Base-T up to 100 meters, so the 50-meter runs and T568B wiring are both compliant. Intermittent connectivity after an upgrade most commonly stems from marginal terminations — a single poorly seated conductor or a bad crimp on one pair can cause link negotiation to flap or drop to lower speeds under Gigabit signaling, which uses all four pairs unlike 100Base-TX.

Answer

The cable runs are too long for 1000Base-T.

Answer

The T568B wiring standard is incompatible with 1000Base-T.

Answer

The network switch ports are set to 100 Mbps full duplex.

Question 14

A small office has an inkjet printer that is printing blank pages even though the ink cartridges are full and properly installed. What is the most likely cause of this problem?

Accepted Answer

The printhead is clogged. A clogged printhead prevents ink from being ejected onto the paper even when cartridges are full and correctly installed, producing blank pages. Inkjet printheads have microscopic nozzles that dry out or clog with dried ink residue when the printer sits idle, blocking all ink flow. Running the built-in cleaning cycle or manually cleaning the printhead typically restores output.

Answer

The printer driver is corrupted

Answer

The paper type setting is wrong

Answer

The USB cable is faulty

Question 15

A user reports that their external monitor connected via USB-C (DisplayPort Alt Mode) works intermittently. When it does work, the resolution is limited to 1920x1080 even though the monitor supports 4K. The laptop supports USB-C with DisplayPort Alt Mode. What is the most likely cause?

Accepted Answer

The USB-C cable is not rated for video or high-speed data.. The most likely cause is that the USB-C cable is not rated for video or high-speed data. USB-C cables vary in capabilities; some only support USB 2.0 data and charging, lacking the necessary wires for DisplayPort Alt Mode or high-bandwidth video, which results in intermittent connectivity and limited resolution.

Answer

The laptop's USB-C port is damaged.

Answer

The monitor's USB-C input is set to a lower resolution in its OSD.

Answer

The graphics driver needs to be updated to support 4K over USB-C.
