AWS Certified Database – Specialty — Question 93

A database specialist must create nightly backups of an Amazon DynamoDB table in a mission-critical workload as part of a disaster recovery strategy.
Which backup methodology should the database specialist use to MINIMIZE management overhead?

Answer options

• A. Install the AWS CLI on an Amazon EC2 instance. Write a CLI command that creates a backup of the DynamoDB table. Create a scheduled job or task that runs the command on a nightly basis.
• B. Create an AWS Lambda function that creates a backup of the DynamoDB table. Create an Amazon CloudWatch Events rule that runs the Lambda function on a nightly basis.
• C. Create a backup plan using AWS Backup, specify a backup frequency of every 24 hours, and give the plan a nightly backup window.
• D. Configure DynamoDB backup and restore for an on-demand backup frequency of every 24 hours.

Correct answer: C

Explanation

The correct answer is C because AWS Backup allows for automated backup management with minimal manual intervention, making it an efficient choice for regular backups. Option A requires manual scripting and scheduling, which increases management overhead. Option B, while automated, involves managing a Lambda function and CloudWatch Events, which can also add complexity. Option D does not provide the same level of automation and management efficiency as AWS Backup.
