A systems administrator has been tasked with disabling the nginx service from the environment to prevent it from being automatically and manually started.

D . systemct1 stop nginx

View Answer

Answer: C

Explanation:

The command systemct1 mask nginx disables the nginx service from the environment and prevents it from being automatically and manually started. This command creates a symbolic link from the service unit file to /dev/null, which makes the service impossible to start. This is the correct way to accomplish the task. The other options are incorrect because they either do not exist (systemct1 cancel nginx), do not prevent manual start (systemct1 disable nginx), or do not prevent automatic start (systemct1 stop nginx).
