You are a systems administrator and have created an uncompressed backup of theapplication directory.

This performance-based question tests correct use of the tar utility for backup and restore operations, which is part of System Management in CompTIA Linux+ V8. The key detail is that the backup is explicitly described as uncompressed, so the correct archive file must be a plain .tar file rather than .tar.gz, .tgz, or .tar.bz2.

For the backup command, the correct syntax is:

tar -cvf /backups/application.tar -C /opt/ application

Here, -c creates the archive, -v enables verbose output, and -f specifies the archive filename. The -C /opt/ option changes to the /opt/ directory before archiving, and application is then archived relative to that location. This is the correct Linux+ method because it avoids storing unnecessary leading path components in the archive.

For the restore command, the correct syntax is:

tar -xvf /backups/application.tar -C /opt/

Here, -x extracts the archive, -v displays files being restored, and -f identifies the archive file. The -C /opt/ option ensures the archived application directory is restored back into /opt/, recreating /opt/application correctly.

The other file choices such as /backups/application.tar.gz, /backups/application.tgz, and /backups/application.tar.bz2 are incorrect because they indicate compressed backups, which the question specifically rules out. Likewise, options such as -xzvf or -xjvf are used for gzip- or bzip2-compressed archives and would not apply here.

Therefore, the verified correct PBQ answers are:

Backup: tar -cvf /backups/application.tar -C /opt/ application

Restore: tar -xvf /backups/application.tar -C /opt/
