ANS-C01 Question #41: Real Exam Question with Answer & Explanation

Question

A real estate company is building an internal application so that real estate agents can upload photos and videos of various properties. The application will store these photos and videos in an Amazon S3 bucket as objects and will use Amazon DynamoDB to store corresponding metadata. The S3 bucket will be configured to publish all PUT events for new object uploads to an Amazon Simple Queue Service (Amazon SQS) queue. A compute cluster of Amazon EC2 instances will poll the SQS queue to find out about newly uploaded objects. The cluster will retrieve new objects, perform proprietary image and video recognition and classification update metadata in DynamoDB and replace the objects with new watermarked objects. The company does not want public IP addresses on the EC2 instances. Which networking design solution will meet these requirements MOST cost-effectively as application usage increases?

• BPlace the EC2 instances in a private subnet. Create a NAT gateway in a public subnet in the
• CPlace the EC2 instances in a private subnet. Create an interface VPC endpoint for Amazon SQS.
• DPlace the EC2 instances in a private subnet. Create a gateway VPC endpoint for Amazon SQS.
