AWS Certified Database – Specialty — Question 109

A banking company recently launched an Amazon RDS for MySQL DB instance as part of a proof-of-concept project. A database specialist has configured automated database snapshots. As a part of routine testing, the database specialist noticed one day that the automated database snapshot was not created.
Which of the following are possible reasons why the snapshot was not created? (Choose two.)

Answer options

• A. A copy of the RDS automated snapshot for this DB instance is in progress within the same AWS Region.
• B. A copy of the RDS automated snapshot for this DB instance is in progress in a different AWS Region.
• C. The RDS maintenance window is not configured.
• D. The RDS DB instance is in the STORAGE_FULL state.
• E. RDS event notifications have not been enabled.

Correct answer: A, D

Explanation

The correct answers are A and D. Option A is valid because if a snapshot is already in progress, the automated snapshot will not be created until that process completes. Option D is also correct since if the DB instance is in the STORAGE_FULL state, it cannot create new snapshots. The other options do not directly prevent automated snapshots from being created.
