Question 50.
A company is running Amazon RDS for PostgreSQL Multi-AZ DB clusters. The company uses an AWS CloudFormation template to create the databases individually with a default size of 100 GB. The company creates the databases every Monday and deletes the databases every Friday. Occasionally, the databases run low on disk space and initiate an Amazon CloudWatch alarm. A SysOps administrator must prevent the databases from running low on disk space in the future. Which solution will meet these requirements with the FEWEST changes to the application?
A
Modify the CloudFormation template to use Amazon Aurora PostgreSQL as the DB engine.
B
Modify the CloudFormation template to use Amazon DynamoDB as the database. Activate storage auto scaling during creation of the tables.
C
Modify the Cloud Formation template to activate storage auto scaling on the existing DB instances.
D
Create a CloudWatch alarm to monitor DB instance storage space. Configure the alarm to invoke the VACUUM command.
