DBS-C01 Management and Operations Practice Question

A company has an Amazon RDS for MySQL DB instance with automated backups enabled. The database is 500 GB in size. The company wants to create a new test database from the current state with minimal impact on production. Which approach meets these requirements?

⚠ Common exam trap

Many candidates confuse the ability to create a manual snapshot from an automated backup (which is not supported) with the valid option of taking a new manual snapshot directly from the DB instance, leading them to choose option D incorrectly.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Take a snapshot of the DB instance and restore it to a new instance.

Taking a snapshot of the RDS DB instance and restoring it to a new instance creates an independent copy of the database with minimal performance impact on the source. Snapshots are asynchronous and capture a consistent state without blocking writes, making this the most efficient method for creating a test database from the current production state.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Take a snapshot of the DB instance and restore it to a new instance.

    Why this is correct

    Snapshots are taken asynchronously with minimal performance impact, and restore creates a new instance.

  • Create a read replica and promote it to a standalone instance.

    Why it's wrong here

    Creating a read replica puts additional load on the source during creation.

  • Use mysqldump to export the database and import into a new instance.

    Why it's wrong here

    mysqldump can cause lock contention and performance impact on production.

  • Create a manual DB snapshot from the automated backup and restore.

    Why it's wrong here

    Manual snapshot is similar to automated; but this approach still requires a snapshot.
