A company is transitioning its Amazon EC2 based MariaDB database to Amazon RDS. The company has already identified a database instance type that will meet the company’s CPU and memory requirements. The database must provide at least 40 GiB of storage capacity and 1,000 IOPS.

Which storage configuration for the Amazon RDS for MariaDB instance is MOST cost-effective?

A

Incorrect. Magnetic storage does not support IOPS as a configurable parameter.

For more information about magnetic storage, see Amazon RDS Storage Types.

B

Incorrect. Baseline I/O performance for General Purpose SSD storage is 3 IOPS for each GiB, with a minimum of 100 IOPS. For 50 GiB of storage, the baseline performance would be 150 IOPS.

C

Correct. Baseline I/O performance for General Purpose SSD storage is 3 IOPS for each GiB. For 334 GiB of storage, the baseline performance would be 1,002 IOPS. Additionally, General Purpose SSD storage is more cost-effective than Provisioned IOPS storage.

For more information about General Purpose SSD storage, see General Purpose SSD Storage.

For more information about Amazon RDS costs, see Amazon RDS for MariaDB Pricing.

D

Incorrect. 50 GiB of Provisioned IOPS storage with 1,000 IOPS would be more expensive than 334 GiB of General Purpose SSD storage.
