Where does the cron daemon look for user-specific scheduled jobs?

In the /var/spool/cron/crontabs directory, with one file per user.

In the user's home directory as a hidden file named .crontab.

In the /etc/cron.d directory, with one file per user.

In the /etc/crontab file only, which contains all users' jobs.

Which statement best describes the role of the cron daemon in a Linux system?

It compiles crontab entries into binary executables for faster startup.

It replaces the system init process to manage background services.

It executes commands immediately when they are submitted by a user.

It reads crontab files and runs the commands they contain at the specified times.

A small office runs a file server that is powered off every night at 20:00 and powered on at 08:00. The administrator needs a daily backup job to run reliably even if the server is off at the scheduled time. Which solution best meets this requirement?

Use the at command to schedule the backup for 02:00 each day.

Configure anacron to run the backup script daily with a delay of 15 minutes after boot.

Place the backup script in /etc/cron.daily/ and rely on run-parts.

Add a cron job in /etc/crontab that runs the backup at 02:00 every day.

A user reports that a cron job runs but the script cannot find a required executable that works fine when run manually from the shell. The script is invoked as `/usr/local/bin/myscript`. Which is the most likely cause and fix?

The script lacks the executable bit; run `chmod +x /usr/local/bin/myscript`.

The cron daemon is running as a different user; switch the job to run as root.

The crontab entry has a syntax error; the job would not run at all.

Cron uses a minimal PATH; the script should use absolute paths or set PATH within the crontab.
