   A backup script needs to copy files from a remote server to a local directory. The script must preserve the directory structure and only copy files that have changed since the last backup. The script should also delete local files that no longer exist on the remote server. Which tool is best suited for this workflow?

   • AUse tar over SSH to create an archive and extract it locally, but this does not delete local files.
   • BUse wget with the -m option to mirror the remote directory, but this does not delete local files.
   • CUse rsync with the -a --delete options to mirror the remote directory to the local backup directory.
   • DUse scp -r to recursively copy the remote directory, and manually delete local files that are not present.

   A DevOps team maintains a fleet of Ubuntu servers. They need a script that installs a list of required packages, but only if they are not already installed, and logs the installation status to a file. The script should also handle the case where the package list file is missing. Which approach best meets these requirements?

   • ALoop through each package in the list file, use dpkg -s to check if it is installed, and if not, run apt-get install -y and append the result to a log; if the list file is missing, print an error and exit.
   • BUse apt-get install -y with the package list as arguments, and redirect output to a log file; if the list file is missing, the script exits with an error message.
   • CRun apt-get update first, then use apt-get install -y with the entire list, and always overwrite the log file; if the list file is missing, the script continues with an empty list.
   • DUse a for loop that reads the list file, but only runs apt-get install -y for the first package and then exits; if the list file is missing, it creates an empty log.
