Explanation

{"question_number": 1, "question": "Resolving a corrupted RPM database", "correct_answer": "D", "explanation": "When the RPM database is corrupted, the proper recovery sequence is: (1) navigate to /var/lib/rpm where the database files live, (2) remove the corrupted lock/database files using 'rm -f _db*', (3) rebuild the database with 'rpm --rebuilddb', and (4) clean the yum cache with 'yum clean all'. Order matters critically here. Option A incorrectly runs --rebuilddb BEFORE removing the corrupt _db* files, meaning the rebuild may fail or use corrupted data. Option B uses 'rpm -qd' (which lists documentation files) as a diagnostic step, which is irrelevant to repair. Option C uses 'rpm -qa' (list all packages) before removing files but never rebuilds the database. Only option D follows the correct sequence: remove corrupted files first, then rebuild, then clean.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
