The Full Control Services Access policy grants users what ability regarding managed services?

The Full Control Services Access policy is designed to provide users with comprehensive privileges over managed services, specifically allowing them to modify service properties and query them. This means that users granted this policy can make changes to how services are configured, adjust their settings, and retrieve information about the services, which is essential for effective management of endpoints and the applications that run on them.

Being able to modify service properties empowers users to tailor the functionality of services to meet the specific needs of their organization, whether that involves changing start-up types, modifying logon configurations, or adjusting dependencies. Additionally, the ability to query these services allows users to gather important operational data, which can be vital for troubleshooting and maintaining system performance.

In contrast, other options may suggest the capabilities associated with managing services, but they don't encompass the complete range of permissions granted under the Full Control Services Access policy. This makes the option related to modification and querying the most fitting description of what this policy provides to users, emphasizing its role in service management and operational control.
