Microsoft Azure Data Fundamentals — Question 292

Which database transaction property ensures that transactional changes to a database are preserved during unexpected operating system restarts?

Answer options

Correct answer: C

Explanation

The correct answer is C, durability, as it ensures that once a transaction has been committed, its changes remain intact even in the event of a system failure. Options A (consistency), B (atomicity), and D (isolation) describe other aspects of transaction management but do not specifically address the preservation of changes after a restart.
