RHCSA RHCSA Systemd and Service Management 4

Question 1

Which systemd unit type is used to mount a filesystem defined in /etc/fstab at a specific path?

Accepted Answer

.mount

Answer

`.mount` units represent filesystem mount points and correspond to entries in `/etc/fstab`.

Question 2

What is the purpose of `systemd-analyze blame`?

Accepted Answer

Lists each unit and the time it took to initialize during boot

Answer

`systemd-analyze blame` shows each service unit's initialization time, helping identify boot bottlenecks.

Question 3

A `Type=forking` service unit is used when the process does what?

Accepted Answer

Daemonizes by forking and having the parent exit

Answer

`Type=forking` is for traditional daemons that fork a child process and exit the parent; systemd tracks the child.

Question 4

Which command creates a systemd override file for `httpd.service` using a text editor?

Accepted Answer

systemctl edit httpd.service

Answer

`systemctl edit httpd.service` opens an editor for a drop-in override file without replacing the original unit.

Question 5

What does `systemctl kill -s SIGKILL httpd.service` do differently from `systemctl stop httpd.service`?

Accepted Answer

It sends SIGKILL directly to all processes in the service's cgroup, bypassing ExecStop=

Answer

`systemctl kill` sends a signal directly to all cgroup members, while `stop` runs the `ExecStop=` sequence.
