When dealing with a suspected virus infection on an air-gapped computer, after an initial scan with Windows Defender shows no infection, the next steps should include examining the event logs to look for suspicious activity and updating the virus definitions for a more thorough scan. Event logs can provide insights into system changes and potential malicious activities, while updated definitions ensure the antivirus software can detect the latest threats. Connecting to the network or enabling the firewall might not be appropriate due to the risk of spreading the infection, and re-imaging the computer or documenting the findings would be subsequent steps if the initial actions don't resolve the issue.References: Official CompTIA A+ Core 1 and Core 2 Student Guide.

The correct answer is A. Verify the DNS server settings. This is because the DNS server is responsible for resolving domain names to IP addresses, which is necessary for accessing the internet or named network resources. If the DNS server settings are incorrect or the DNS server is down, the technician will not be able to access these resources even if they have a valid IP address and can ping the default gateway1.

Group Policy is a feature of Windows that allows administrators to manage and configure settings for computers and users on a network12. One of the settings that can be controlled by Group Policy is the password policy, which defines the rules for creating and changing passwords, such as minimum length, complexity, expiration, and history34. By using Group Policy, the Chief Information Officer can enforce the new password length requirement for all users and computers in the company's domain, without having to manually adjust each user account or device.
