AWS Certified Cloud Practitioner — Question 265

Which AWS service provides automated backups of data by default?

Answer options

• A. Amazon S3
• B. Amazon Aurora
• C. Amazon ElastiCache for Memcached
• D. Amazon Elastic File System (Amazon EFS)

Correct answer: B

Explanation

Amazon Aurora automatically enables continuous, incremental backups by default, allowing point-in-time recovery during the retention period. In contrast, Amazon S3 and Amazon EFS require manual configuration or integration with other services like AWS Backup to automate backups, while ElastiCache for Memcached does not support backup and restore functionality at all.
