Question 42/136

A junior administrator updated the PostgreSQL service unit file per the data-base administrator's recommendation. The service has been restarted, but changes have not been applied. Which of the following should the administrator run for the changes to take effect?

A. Systemct1 get-default

B. systemct1 daemon-reload

C. systemct1 enable postgresq1

D. systemct1 mask postgresq1

Correct Answer: B

To apply changes to a systemd service unit file, the administrator needs to reload the systemd daemon using the command systemct1 daemon-reload (B). This will make systemd aware of the new or changed unit files. The other commands will not reload the systemd daemon or apply the changes. Reference:
[CompTIA Linux+ Study Guide], Chapter 7: Managing System Services, Section: Modifying Systemd Services
