AWS Certified Security – Specialty (SCS-C02) — Question 193

A company hosts an application on Amazon EC2 instances. The application also uses Amazon S3 and Amazon Simple Queue Service (Amazon SQS). The application is behind an Application Load Balancer (ALB) and scales with AWS Auto Scaling.

The company's security policy requires the use of least privilege access, which has been applied to all existing AWS resources. A security engineer needs to implement private connectivity to AWS services.

Which combination of steps should the security engineer take to meet this requirement? (Choose three.)

Answer options

• A. Use an interface VPC endpoint for Amazon SQS.
• B. Configure a connection to Amazon S3 through AWS Transit Gateway.
• C. Use a gateway VPC endpoint for Amazon S3.
• D. Modify the IAM role applied to the EC2 instances in the Auto Scaling group to allow outbound traffic to the interface endpoints.
• E. Modify the endpoint policies on all VPC endpoints. Specify the SQS and S3 resources that the application uses.
• F. Configure a connection to Amazon S3 through AWS Firewall Manager.

Correct answer: A, C, E

Explanation

The correct steps involve using an interface VPC endpoint for Amazon SQS (A), a gateway VPC endpoint for Amazon S3 (C), and modifying the endpoint policies to restrict access to only the necessary S3 and SQS resources (E). Options B and F are incorrect as they do not align with the least privilege principle and do not leverage the VPC endpoints effectively, while option D is unnecessary since the IAM roles should already be configured to support private connectivity.
