A customer wants to replicate their database for the accounting and finance departments. What is a benefit of accomplishing this with a clone replication technology?

Question

Options

• AIt uses less storage than a snapshot copy.
• BIt creates an exact copy of the database.
• CIt identifies index corruption on the database.
• DIt provides continuous data protection.

• B
  96% (24)
• D
  4% (1)

Explanation

Clone replication is defined by its ability to produce an exact, bit-for-bit duplicate of the source database at a point in time - making B the correct answer. This is precisely why it's useful here: both accounting and finance get an identical, independent copy of the database to work from without impacting production.

Why the distractors are wrong:

• A is incorrect because clones are full copies and typically consume similar or more storage than the source; snapshot technologies (like copy-on-write snapshots) are the storage-efficient option.
• C is incorrect because identifying index corruption is a database integrity/maintenance function (e.g., DBCC CHECKDB in SQL Server), not a replication feature.
• D is incorrect because continuous data protection (CDP) is a separate technology that captures changes in real time; a clone is a point-in-time copy, not an ongoing protection mechanism.

Memory tip: Think of "clone" like a biological clone - it's an exact duplicate, nothing more, nothing less. If an answer choice describes something beyond simple copying (storage savings, corruption detection, continuous protection), it's describing a different technology entirely.
