A technician needs to upgrade the operating system on 200 lab computers to the latest version of Linux. Which of the following is the fastest upgrade method?
Show answer
Answer: C
Explanation
For upgrading the operating system on 200 lab computers to the latest version of Linux, the fastest method would be C. Installing from a network share. Installing from a network share allows the technician to deploy the operating system upgrade to multiple computers simultaneously over the network. This method is faster than starting up from a USB flash drive or cloning each computer's hard drive individually. Additionally, it is more efficient than using the Windows Subsystem for Linux, as it doesn't involve installing Linux within a Windows environment, which could introduce complexity and potential compatibility issues.

Question 476 · 683 in bank
A user’s antivirus software reports an infection that it is unable to remove. Which of the following is the most appropriate way to remediate the issue?
Show answer
Answer: C
Explanation
The confusion here comes from the way the term "remediate" is understood in the context of IT security. So while quarantining doesn't directly remove the infection, it is the right answer in this context because it is the first necessary action to take before the issue can be fully resolved. The exam often focuses on best practices and proper procedures, and in security, containment is always the first and most important step.

This helps minimize risks associated with changes and increases the likelihood of successful deployment.
