Question 1

Afield technician is responding to a ticket about an animated sign with double images. One image is stationary, and the other image is live. Which of the following is the cause of the issue?

Answer : C

Display burn-in occurs when a static image is left on a screen for a long time, causing the pixels to wear out unevenly and retain a ghost image even when new content is displayed. This issue can result in double images, where the 'burned-in' stationary image persists alongside new, live content. This problem is more common in older displays or those used for static signage. Replacing the display cable or adjusting color settings would not address the underlying cause of uneven pixel wear, and burned-out bulbs would likely result in a loss of image clarity or brightness, not double images.

Question 2

Which of the following cloud service models is most likely to provide application patching?

Answer : D

In the SaaS (Software as a Service) model, the service provider manages the infrastructure, platforms, and software applications, including maintenance tasks such as application patching. Users access the applications over the internet, and the provider is responsible for ensuring the software is up to date, secure, and performing optimally. This model contrasts with IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), where the customer has more control and responsibility over the environment and may need to manage patching for applications they develop or install.

Question 3

Users have been reporting slow network traffic in a branch office, and the technician needs to determine if packet loss is occurring on the network. Which of the following would the technician most likely use to passively assess the network traffic issue?

Answer : B

A network tap (Test Access Point) is a device used for monitoring network traffic. It allows the technician to passively observe the traffic between two network nodes in real-time without introducing latency or affecting the network's performance. By using a network tap, the technician can analyze the data packets flowing through the network to identify if packet loss is occurring, which could be contributing to the slow network traffic in the branch office.

Question 4

Every time a user submits a print job, the user receives an error from the printer requesting A4 paper. No other users in the office are having printing issues. Which of the following is the best way to address the user's issue?

Answer : C

When a user consistently receives an error requesting A4 paper for print jobs, and no other users are experiencing similar issues, it indicates a possible misconfiguration in the user's printer settings. By setting the printer defaults in the Control Panel to use letter-sized paper, which is more common in some regions, this ensures that the user's print jobs are aligned with the available paper size in the office printer. This approach addresses the root cause of the issue by ensuring that the default settings match the paper size used in the office, eliminating the need for the user to adjust settings for each print job.

Question 5

A user states that when docking a laptop, network drives are lost. However, when working wirelessly, network drives are present. While troubleshooting, a technician does not see any recent infrastructure changes and thinks the laptop has a bad network card. The technician orders a new laptop for the user and closes the ticket documenting the new laptop. After receiving the new laptop, the user still cannot access network drives when docked. Which of the following steps did the technician skip?

Answer : B

The technician failed to properly diagnose the issue by not establishing a theory of probable cause. Instead of investigating why the network drives were accessible wirelessly but not when docked, the technician assumed a faulty network card and ordered a new laptop. Proper troubleshooting involves developing a theory of what might be causing the problem, based on the symptoms and available information, and then testing that theory. In this case, the issue could have been related to docking station settings, network configurations, or hardware issues specific to the docking connection.

Question 6

A company gives users microSD cards to install on smartphones so users can store pictures that will be used on the website. After installing the cards, users report only being able to save a small number of pictures on the microSD cards before running out of space. Which of the following is the most likely issue?

Answer : A

If users are only able to save a small number of pictures on the microSD cards before running out of space, it suggests a formatting issue. Improper or incomplete formatting can lead to the card not utilizing its full storage capacity, resulting in significantly less available space for storing pictures. Formatting the microSD cards correctly would ensure the file system on the cards is set up properly, allowing the devices to use the full capacity of the cards for storage. Compatibility, UHD storage capability, and camera storage settings are less likely to be the issue in this scenario.

Question 7

A user is unable to get a laptop screen to display on the conference room TV. The room has an in-room computer, which is currently being displayed on the TV screen. The user has plugged the laptop into the conference room's wireless HDMI dongle, but the TV screen is still showing the in-room computer desktop. Which of the following should the user do to most likely resolve the issue?

Answer : C

When a laptop screen is not displaying on a conference room TV despite being connected to a wireless HDMI dongle, the issue is often related to the TV being set to the wrong input source. Since the in-room computer's desktop is displayed, it suggests the TV is currently set to the input source used by the in-room computer. Changing the TV's input source to the one associated with the wireless HDMI dongle connected to the user's laptop is the simplest and most direct approach to resolve the issue. This does not involve adjusting network settings or hardware configurations but rather selecting the correct input source through the TV's input selection menu.
