tracert. This question tests knowledge of network diagnostic commands. Tracert (or traceroute) shows the route packets take and measures latency at each hop, helping to pinpoint where delays or failures occur.

Answer

ping

Answer

ipconfig

Answer

nslookup

Question 2

Accepted Answer

Wi-Fi analyzer. This question tests understanding of wireless connectivity tools. A Wi-Fi analyzer can detect available networks and signal strength, helping to confirm if the adapter is working and seeing the network.

Answer

Cable tester

Answer

Loopback plug

Answer

Multimeter

Question 3

You are setting up a new branch office and need to run Ethernet cables through ceiling plenums. You must ensure the cables meet fire safety codes. Which type of cable should you use, and which tool would you use to verify its integrity after installation?

Accepted Answer

Answer

Toner probe; it can measure signal strength

Answer

Multimeter; it can measure resistance

Answer

Loopback plug; it can simulate network traffic

Question 5

You are troubleshooting a network where users in one department cannot reach a critical server. You need to check if the server's IP address is reachable and measure the round-trip time. Which command-line tool provides this information?

Accepted Answer

ping. This question tests understanding of basic network diagnostic commands. Ping sends ICMP echo requests to a host and measures response time, confirming reachability and latency.

Answer

tracert

Answer

nslookup

Answer

netstat

Question 6

A user reports that their external monitor connected via HDMI shows a blurry image and the text is hard to read. They have tried a different HDMI cable and the issue persists. What is the most likely cause?

Accepted Answer

The display resolution is set below the monitor's native resolution.. This scenario tests understanding of display resolution settings. The most common cause of blurry text on an external monitor is incorrect resolution scaling, not a cable or driver issue. Adjusting the display resolution to the monitor's native resolution will usually fix the problem.

Answer

The HDMI cable is defective.

Answer

The monitor's refresh rate is set too low.

Answer

The graphics driver is corrupted.

Question 7

A customer wants to connect a laptop to a 4K TV for a presentation. The laptop has an HDMI 1.4 port, and the TV supports HDMI 2.0. What is the maximum resolution and refresh rate the customer can expect?

Accepted Answer

4K at 30Hz. HDMI 1.4 supports 4K resolution at 30Hz, while HDMI 2.0 supports 4K at 60Hz. The bottleneck is the laptop's HDMI 1.4 port, so the output will be limited to 4K at 30Hz.

Answer

4K at 60Hz

Answer

1080p at 120Hz

Answer

1440p at 60Hz

Question 8

A technician is installing a new LCD monitor for a user who does photo editing. The user complains that colors appear washed out compared to their old CRT monitor. What should the technician adjust first?

Accepted Answer

Adjust the color settings in the monitor's on-screen display.. LCD monitors often have different color gamuts and settings than CRTs. The most straightforward fix is to adjust the color calibration settings in the monitor's OSD or OS to improve color accuracy.

Answer

Replace the video cable with a DVI cable.

Answer

Update the graphics driver.

Answer

Set the resolution to the monitor's native resolution.

Question 9

A user's laptop screen flickers intermittently, but the external monitor works fine. What is the most likely cause?

Accepted Answer

The display cable connecting the motherboard to the screen is loose or damaged.. Since the external monitor works fine, the issue is likely with the laptop's display components. A loose or failing display cable is a common cause of intermittent flickering on built-in screens.

Answer

The graphics driver is outdated.

Answer

The LCD panel is failing.

Answer

The inverter or backlight is failing.

Question 10

A customer wants to use a 34-inch ultrawide monitor (3440x1440) with their desktop PC. The PC has an older GPU with a DVI-D dual-link port and an HDMI 1.4 port. Which connection should the technician recommend for the best image quality?

Accepted Answer

HDMI 1.4. 3440x1440 at 60Hz requires significant bandwidth. HDMI 1.4 can support this resolution at 60Hz, but DVI-D dual-link can also handle it. However, HDMI is generally preferred for modern monitors, and DVI-D dual-link is less common. The correct answer is HDMI 1.4, as it can support the resolution and is more versatile.

Answer

DVI-D dual-link

Answer

VGA

Answer

DisplayPort

Question 11

A user reports that their monitor displays a 'No Signal' message when they turn on their computer. The monitor is connected via DisplayPort. The technician checks that the monitor is powered on and the cable is secure. What should the technician check next?

Accepted Answer

Try a different DisplayPort cable or port on the GPU.. DisplayPort cables can sometimes have issues with the locking mechanism or be partially unseated. The next logical step is to try a different DisplayPort cable or port on the GPU to isolate the issue.

Answer

Replace the monitor.

Answer

Check the input source setting on the monitor.

Answer

Update the graphics driver.

Question 12

A technician is configuring a dual-monitor setup for a stock trader. One monitor is a 24-inch 1080p display, and the other is a 27-inch 4K display. The user wants the mouse to move seamlessly between them. What setting must the technician configure in the OS display settings?

Accepted Answer

Arrange the displays in the OS to match their physical positions.. When using monitors with different resolutions, the OS must align the virtual displays correctly. The technician needs to arrange the monitors in the display settings to match their physical layout, ensuring the mouse moves smoothly across the bezels.

Answer

Set both monitors to the same resolution.

Answer

Adjust the scaling settings on the 4K monitor.

Answer

Set the 4K monitor as the primary display.

Question 13

A user's laptop screen has a small crack in the corner, and the display shows lines and discoloration in that area. The rest of the screen works. What is the most cost-effective solution?

Accepted Answer

Replace the LCD panel.. A cracked LCD panel requires replacement of the entire screen assembly, not just the glass. Replacing the whole LCD panel is the standard and most cost-effective repair for this type of physical damage.

Answer

Replace the entire laptop.

Answer

Replace the display cable.

Answer

Use an external monitor permanently.

Question 14

A technician is troubleshooting a monitor that displays a 'fuzzy' image with ghosting. The monitor is connected via VGA. The technician has already tried a different VGA cable and the issue persists. What should the technician check next?

Accepted Answer

Route the VGA cable away from power cables and other electronics.. VGA is an analog signal that can be affected by electrical interference. Ghosting and fuzziness are classic symptoms of interference from nearby power cables or other electronics. Moving the VGA cable away from power sources is the next logical step.

Answer

Replace the monitor.

Answer

Change the resolution to a lower setting.

Answer

Update the graphics driver.

Question 15

A user's all-in-one PC has a touchscreen that is not responding correctly. The technician calibrates the touchscreen, but the issue persists. The technician then notices that the screen is slightly misaligned with the bezel. What is the most likely cause?

Accepted Answer

The LCD panel has shifted inside the chassis.. A misaligned screen relative to the bezel suggests that the LCD panel has shifted inside the chassis. This physical misalignment can cause the touch sensor to be out of sync with the display, leading to touch inaccuracies that calibration cannot fix.

Answer

The touchscreen driver is corrupted.

Answer

The digitizer is failing.

Answer

The operating system needs a touchscreen firmware update.
