Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
dpkg --verify
Why this is correct
dpkg --verify (or dpkg -V) checks files installed by packages against the database to detect modifications.
- ✗
rpm -Va
Why it's wrong here
rpm -Va is used on RPM-based systems (RedHat/CentOS), not Debian/Ubuntu.
- ✗
debsums -ac
Why it's wrong here
While debsums checks sums, dpkg --verify is the native dpkg suite tool for comprehensive file state verification.
- ✗
apt-get check-integrity
Why it's wrong here
apt-get check-integrity is not a valid apt-get command; apt verifies dependency graphs.
