To disable the service vmtoolsd.service, the correct approach is to use the command "systemctl disable vmtoolsd.service." This command prevents the service from starting automatically at boot time, effectively disabling it in a persistent manner. Disabling a service is essential when you want to stop it from running in future sessions without affecting the current operational state.

The "systemctl disable" command specifically modifies the service's symbolic links in the system’s configuration to ensure it isn't activated on system startup. This contrasts with simply using "systemctl stop," which only halts the service for the current session. The other options are also not valid for the purpose of disabling a service. "systemctl deactivate" and "systemctl end" are not recognized commands in systemd service management. Therefore, using "systemctl disable vmtoolsd.service" is the correct method to ensure that a service does not automatically start in the future.
