AWS Certified Solutions Architect – Associate (SAA-C02) — Question 118

A company is planning to migrate its virtual server-based workloads to AWS. The company has internet-facing load balancers backed by application servers. The application servers rely on patches from an internet-hosted repository.
Which services should a solutions architect recommend be hosted on the public subnet? (Choose two.)

Answer options

• A. NAT gateway
• B. Amazon RDS DB instances
• C. Application Load Balancers
• D. Amazon EC2 application servers
• E. Amazon Elastic File System (Amazon EFS) volumes

Correct answer: A, C

Explanation

The NAT gateway and Application Load Balancers are appropriate for the public subnet as they need to be accessible from the internet. Other options such as Amazon RDS DB instances and Amazon EC2 application servers are typically hosted in private subnets due to security considerations, while Amazon EFS volumes are used for shared file storage and are not specifically tied to public access.
