What database high availability option allows multiple clients to access multiple database servers simultaneously?

What database high availability option allows multiple clients to access multiple database servers simultaneously?

A.
Database commit

B.
Database journal

C.
Replicated database

D.
Shadow database

Explanation:
Answer C is correct; Database replication mirrors a live database, allowing simultaneous reads and writes to multiple replicated databases by clients.

Incorrect Answers and Explanations: A, B, and D: Answers A, B, and D are incorrect. DBMSs may attempt to commit updates: make the pending changes permanent. A database journal is a log of all database transactions. A shadow database is similar to a replicated database, with one key difference: a shadow database mirrors all changes made to a primary database, but clients do not access the shadow.
