AWS Certified Solutions Architect – Associate (SAA-C02) — Question 230

A company hosts its static website content from an Amazon S3 bucket in the us-east-1 Region. Content is made available through an Amazon CloudFront origin pointing to that bucket. Cross-Region replication is set to create a second copy of the bucket in the ap-southeast-1 Region. Management wants a solution that provides greater availability for the website.
Which combination of actions should a solutions architect take to increase availability? (Choose two.)

Answer options

• A. Add both buckets to the CloudFront origin.
• B. Configure failover routing in Amazon Route 53.
• C. Create a record in Amazon Route 53 pointing to the replica bucket.
• D. Create an additional CloudFront origin pointing to the ap-southeast-1 bucket.
• E. Set up a CloudFront origin group with the us-east-1 bucket as the primary and the ap-southeast-1 bucket as the secondary.

Correct answer: D, E

Explanation

Option D is correct because adding another CloudFront origin for the ap-southeast-1 bucket allows for redundancy in serving content. Option E is also correct as it creates an origin group, which enables automatic failover to the secondary bucket if the primary is unavailable, enhancing availability. The other options either do not provide the needed redundancy or do not directly address availability improvement.
