An engineer is writing a script that must create a temporary directory, download a file into it, and then clean up the directory when the script exits, even if the script fails. Which approach ensures the cleanup happens reliably?

Use mktemp -d and delete the directory manually after the download.

Use a trap command to delete the directory on EXIT.

Create the directory, download the file, and delete the directory at the end of the script.

Create the directory in /tmp and rely on the system to clean it up.

A team has a Bash script that needs to use a shared API token. The token is currently stored in a file with restrictive permissions. The team wants to load the token into an environment variable without exposing it in the process list. Which approach is most secure?

Use a secret management tool to inject the token into the environment at runtime.

Read the token from the file directly in the script without setting an environment variable.

export API_TOKEN=$(cat /path/to/token)

Use a configuration file that is sourced by the script, with the token as a variable.

A backup script needs to copy files from /var/lib/app to /backup, but the destination is on a different filesystem. The script must preserve file permissions and timestamps. Which command should be used?

`rsync -r /var/lib/app/ /backup/`

`cp -a /var/lib/app/. /backup/`

`cp -r /var/lib/app/* /backup/`
