Which package management tools can be used to verify the integrity of installed files on a Linux system?

Question

Options

• ARPM and DPKG
• BAPT and YUM
• Cdpkg and aptitude
• Dyum and zypper

• A
  88% (49)
• B
  2% (1)
• C
  7% (4)
• D
  4% (2)

Explanation

RPM and DPKG are the low-level package managers that include built-in file integrity verification commands: rpm -V <package> checks files against checksums stored in the RPM database, and dpkg --verify <package> does the same using the dpkg database - both report mismatches in permissions, size, or checksums.

Option B (APT and YUM) are wrong because these are high-level front-ends that handle dependency resolution and downloading; they delegate the actual package-level operations to RPM and DPKG respectively and lack dedicated integrity-check commands.

Option C (dpkg and aptitude) is wrong because aptitude is another high-level front-end (like APT) for Debian systems, not a low-level tool with integrity verification.

Option D (yum and zypper) is wrong for the same reason - both are high-level package managers (yum for RHEL/CentOS, zypper for openSUSE) that rely on RPM underneath.

Memory tip: Think "low-level = verify" - RPM and DPKG are the foundational tools that own the package database, so they're the ones that can check files against it. The acronym RD (RPM + DPKG) matches the Red Hat and Debian families.
