question 8

Multiple Choice

A company is developing a new web application. An AWS CloudFormation template was created as a part of the build process. Recently, a change was made to an AWS::RDS::DBInstance resource in the template. The CharacterSetName property was changed to allow the application to process international text.

What should a database specialist do to prevent data loss during the stack upgrade?

• A) Create a snapshot of the DB instance. Modify the template to add the DBSnapshotIdentifier property with the ID of the DB snapshot. Update the stack.
• B) Modify the stack policy using the aws cloudformation update-stack command and the set-stack-policy command, then make the DB resource protected.
• C) Create a snapshot of the DB instance. Update the stack. Restore the database to a new instance.
• D) Deactivate any applications that are using the DB instance. Create a snapshot of the DB instance. Modify the template to add the DBSnapshotIdentifier property with the ID of the DB snapshot. Update the stack and reactivate the applications.
