RHCSA RHCSA Systemd and Service Management 5

Question 1

Which directive in a unit file's `[Service]` section sets environment variables for the process?

Accepted Answer

Environment=

Answer

`Environment=` sets key=value environment variables directly in the unit file's `[Service]` section.

Question 2

How do you make journald persist logs across reboots on a RHEL system where it is not yet doing so?

Accepted Answer

Create /var/log/journal/ directory and restart systemd-journald

Answer

Creating `/var/log/journal/` causes journald to automatically switch to persistent storage on restart.

Question 3

A unit file has `ConditionPathExists=/etc/myapp.conf`. What happens if that file does not exist when the unit is started?

Accepted Answer

The unit is skipped silently as if it succeeded

Answer

When a `Condition*=` check fails, systemd skips the unit without error — it reports as 'success' but does nothing.

Question 4

Which systemctl subcommand shows all currently loaded and active socket units?

Accepted Answer

systemctl list-units --type=socket

Answer

`systemctl list-units --type=socket` filters the active unit list to show only socket units.

Question 5

What is the correct way to view the full content of a unit file including overrides using systemctl?

Accepted Answer

systemctl cat httpd.service

Answer

`systemctl cat` prints the full unit file content including all applicable drop-in override files.
