Which two security settings can be controlled using group policy?

The first choice accurately highlights two important security settings that can be managed through Group Policy in a Windows environment. Password complexity ensures that users create strong passwords that meet certain criteria, which helps prevent unauthorized access to accounts. This is a crucial security measure as weak passwords can easily be guessed or cracked by attackers.

Controlling access to the Run command is also significant since it allows administrators to prevent users from running unapproved or potentially harmful applications. By restricting this command through Group Policy, organizations can further safeguard their systems against malicious software or unintended system changes.

The other choices, while containing security-related elements, do not fully align with what can be controlled specifically through Group Policy. Disk encryption and firewall settings can also be managed in certain contexts, but they are typically configured through specific administrative tools rather than broad Group Policy settings alone. Similarly, physical security measures and data backups fall outside the realm of Group Policy since they pertain to processes and equipment rather than software settings. Lastly, while antivirus updates and user access levels are important security considerations, they involve a range of configurations, not all of which can be directly manipulated via Group Policy.
