Disconnecting the computer helps prevent any potential malware from communicating with its controller or spreading to other systems, and reporting to IT security allows for a proper response to the incident.
Option A is incorrect because continuing to work without taking action could allow potential malware or a breach to worsen.
Option B is incorrect because changing passwords immediately without first securing the system might not prevent further damage if malware has been installed.
Option D is incorrect because simply deleting the email does not mitigate the risk if the link has already been clicked.

Correct Answer. B. Set the display to turn off after a shorter period of inactivity Adjusting the power settings to turn off the display after a shorter period of inactivity can significantly conserve battery life, as the display is one of the largest consumers of battery power on a laptop.
Option A is incorrect because increasing the screen brightness would actually consume more battery power Option C is incorrect because disabling sleep mode would lead to higher power consumption when the laptop is not actively used Option D is incorrect as setting the processor's minimum state to 100% would increase power consumption, not decrease it

Correct Answer. B. Check the HDMI cable and connection Ensuring that the HDMI cable is properly connected and functional is a fundamental first step in troubleshooting connectivity issues between a MacBook and an external monitor.
Option A is incorrect because replacing the MacBook is unnecessary without first checking simpler issues Option C is incorrect because increasing screen resolution does not affect whether the MacBook recognizes an external display Option D is incorrect as AirPlay mirroring is used for wireless connections and is unrelated to physical HDMI connections

Correct Answer. B. System Information utility The System Information utility on a Mac provides extensive details about the hardware, including the processor type, speed, and other specifications, which are necessary to determine compatibility with software applications.
Option A is incorrect because About This Mac provides only basic information about the processor, such as the type and model, but lacks detailed specifications.
Option C is incorrect because the Terminal command, while detailed, may provide too much technical data that is difficult for average users to interpret accurately.
Option D is incorrect because the Activity Monitor primarily focuses on the current usage of the CPU rather than its specifications.

Correct Answer. C. Cross-reference multiple articles to ensure a comprehensive understanding of similar past issues Cross-referencing allows technicians to understand various angles and solutions that have been effective in the past, providing a thorough background for making informed decisions.
Option A is incorrect because older solutions may not be relevant to current software environments or bug manifestations.
Option B is incorrect as recent articles alone may not capture the full context or range of solutions necessary for effective troubleshooting.
Option D is incorrect because complexity does not inherently correlate with effectiveness, and simpler solutions may often be more appropriate.
