Final answer:
Joining a computer to an Active Directory domain provides the advantage of centralized network management, making administration easier and more efficient. The correct answer is b) Centralized network management.
Step-by-step explanation:
Joining a computer to an Active Directory domain provides the advantage of centralized network management. This means that all network resources, such as user accounts, security policies, and group settings, can be managed and configured from a single location, making administration easier and more efficient.
Increased processing speed, enhanced graphics performance, and improved battery life are not direct advantages of joining a computer to an Active Directory domain. These factors are more dependent on hardware specifications, software optimizations, and power management settings.
This means that users and computers can be managed from a central location, simplifying tasks such as deploying software, applying security policies, and managing user permissions.
Active Directory does not inherently increase processing speed, enhance graphics performance, or improve battery life.
