[All AWS Certified Database - Specialty Questions]

A database specialist was alerted that a production Amazon RDS MariaDB instance with 100 GB of storage was out of space. In response, the database specialist modified the DB instance and added 50 GB of storage capacity. Three hours later, a new alert is generated due to a lack of free space on the same DB instance.
The database specialist decides to modify the instance immediately to increase its storage capacity by 20 GB.
What will happen when the modification is submitted?

  • A. The request will fail because this storage capacity is too large.
  • B. The request will succeed only if the primary instance is in active status.
  • C. The request will succeed only if CPU utilization is less than 10%.
  • D. The request will fail as the most recent modification was too soon.

Selected Answer: D
Answer is D - cannot modify storage until EITHER 6 hours have passed OR the "storage-optimization" status is complete (instance will show "storage-optimization" happens after previous storage capacity has increased -it CAN take more than 6 hours) https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PIOPS.StorageTypes.html

D Storage optimization can take several hours. You can't make further storage modifications for either six (6) hours or until storage optimization has completed on the instance, whichever is longer.

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PIOPS.StorageTypes.html - either 6 hours or when the first job completes - I would go with D too
