Correct Answer. C. Ensuring the cable is not longer than 100 meters to avoid signal degradation Ethernet standards typically recommend a maximum cable length of 100 meters for unshielded twisted pair (UTP) cabling to prevent signal degradation and loss. Using a cable that exceeds this length can result in reduced performance and connection issues.
Option A is incorrect because while cable color can help with organization and safety, it does not impact the functionality regarding signal quality.
Option B is incorrect because using a cable that exceeds 100 meters is against standard recommendations for maintaining optimal Ethernet performance.
Option D is incorrect because an Ethernet cable with multiple RJ-45 connectors isn't standard and doesn't address the issue of signal degradation due to excessive length.

Correct Answer. C. Adjust the brightness manually Manually adjusting the brightness can help balance visibility against glare in different lighting conditions, allowing the user to optimize the display based on the specific environment of the room.
Option A is incorrect because turning off True Tone affects color accuracy and may not effectively reduce glare Option B is incorrect as Night Shift modifies the color temperature primarily for evening use and is not intended for managing glare Option D is incorrect although an anti-glare screen protector is effective, it is a physical addition and not a setting adjustment on the MacOS

Correct Answer. B. Ensure that all VNC software is properly closed and the user's system is secured After completing a session, it is essential to close all related software and confirm that the user's system is secure to prevent unauthorized access and ensure the user's privacy is maintained.
Option A is incorrect because starting another session without a new request or identified issue may not be necessary and could invade the user's privacy.
Option C is incorrect because leaving an open connection can be a significant security risk.
Option D is incorrect as uninstalling VNC might not be necessary if the user requires ongoing support; however, ensuring it is secure after use is critical.

Correct Answer. C. Replace the paper feed rollers in the bypass tray Worn or dirty paper feed rollers can cause frequent jams, especially when using trays that handle special media like the bypass tray. Replacing or cleaning the rollers is typically the first step in resolving these issues.
Option A is incorrect. Network settings would not cause physical paper jams.
Option B is incorrect. Firmware updates are less likely to affect mechanical issues such as paper jams unless the update specifically addresses this.
Option D is incorrect. While paper quality can affect jamming, this is generally not the first step if the jams are frequent and specifically occur when using the bypass tray.

Correct Answer. C. Secure the documentation and ensure it is accessible only to authorized personnel Securing proprietary documentation ensures that sensitive information remains confidential and is only available to those who require it for their work, complying with best security practices.
Option A is incorrect because copying sensitive documentation for personal use breaches confidentiality policies.
Option B is incorrect because sharing proprietary information publicly violates confidentiality and can lead to significant security risks.
Option D is incorrect as deleting official documentation can result in loss of vital information necessary for operations or further maintenance.
