Explanation

mongodump and mongorestore are MongoDB's native backup and recovery tools - mongodump exports data from a running MongoDB instance into BSON files, while mongorestore imports those files back into a MongoDB deployment, making A correct.

Why the distractors are wrong:

• B (audit): MongoDB auditing tracks who did what and when - handled by MongoDB's audit log feature, not dump/restore.
• C (performance tuning): Performance is addressed through indexing, query optimization, and tools like explain() or MongoDB Atlas Performance Advisor.
• D (replication): Replication is a built-in MongoDB feature using replica sets, configured via rs.initiate() - completely separate from backup tooling.

Memory tip: Think of the names literally - "dump" a copy of your data out, "restore" it back in. The word dump is a classic backup term (like SQL's mysqldump), so whenever you see these two tools paired together, think backup/restore pair.
