Which command is used to stop the ActiveGate service on Linux?

The capability to stop the ActiveGate service on Linux is primarily demonstrated through the third option, which indicates the command structure for managing the service. It highlights that the service can be controlled using the service command followed by the service name and an action such as stop, start, or forcestop. The notation provided illustrates that there are various commands available for the service that enable the user to manage its state effectively, including stopping it.

Using service dynatracegateway stop (as seen in the first choice) is a valid command specifically for stopping the service, indicating that stopping the ActiveGate service is possible through this command. However, the broader context in the third option makes it more comprehensive by showing that the service can be managed in multiple ways using the structure provided.

The second option, service dynatracegateway restart, is focused exclusively on restarting the service, which is not relevant to stopping it.

The fourth option, systemctl stop dynatracegateway, is also a valid command that specifically addresses stopping the service but utilizes a different management system for services (systemd) rather than the overarching approach indicated in the correct answer.

Hence, option C presents a more inclusive command usage for controlling the ActiveGate service,
