After updating a configuration file for the 'chronyd' service, an engineer wants the playbook to apply the change only if the file was actually modified. Which task should be used?

command: systemctl restart chronyd, always run

lineinfile: path=/etc/chrony.conf line='...' notify: restart chronyd, and a handler that restarts the service

service: name=chronyd state=restarted, with a notify handler that restarts the service

service: name=chronyd state=started, with a handler that reloads the service

An administrator needs to ensure that the 'chronyd' service is running and will start automatically after a reboot on a set of RHEL hosts. The playbook also needs to apply a new time server configuration. Which tasks should be used?

service: name=chronyd state=restarted; template: src=chrony.conf.j2 dest=/etc/chrony.conf

template: src=chrony.conf.j2 dest=/etc/chrony.conf; systemd: name=chronyd state=restarted enabled=yes

systemd: name=chronyd state=started enabled=yes; lineinfile: path=/etc/chrony.conf regexp='^server' line='server time.example.com'

copy: src=chrony.conf dest=/etc/chrony.conf; service: name=chronyd state=started

An Ansible playbook must configure the 'postgresql' service to listen on a custom port (5433) and ensure the service is running. The configuration file is large, and only the port setting needs to change. The playbook should be idempotent and avoid unnecessary restarts. Which approach is best?

Use lineinfile to change the 'port' directive, register the result, and use a handler to restart the service only when the file changes.

Use copy to replace the config file with a static version and restart the service.

Use template to overwrite the entire config file with the new port and always restart the service.

Use command to run sed to change the port and restart the service.

An engineer is troubleshooting a playbook that manages the 'sshd' service. The playbook uses the service module with state=restarted, but after running the playbook, the SSH service is not running. The engineer suspects the configuration file has a syntax error. Which Ansible feature should be used to prevent this issue?

Use the service module with state=reloaded instead of restarted

Use the command module to run 'sshd -t' before the restart, and use the 'failed_when' condition to stop the playbook if the test fails

Use the copy module to back up the config before restarting

Use the service module with state=started and enabled=yes
