A company runs an application in a VPC with public and private subnets across multiple Availability Zones. The application runs on EC2 instances in private subnets and uses an Amazon SQS queue. Design a secure connection between the EC2 instances and the SQS queue. Which solution meets these requirements?

The correct solution uses an interface VPC endpoint for SQS, which allows private connectivity from EC2 instances in private subnets to SQS without traversing the internet. Configuring the endpoint in private subnets ensures traffic remains within the private network. A security group on the endpoint, allowing inbound traffic from the EC2 instances' security groups, correctly restricts access to authorized sources. The other options are incorrect because: Using public subnets for the endpoint would expose it to the internet, which is less secure and unnecessary for private subnet communication. A gateway endpoint is not available for SQS; it's used for S3 and DynamoDB. A NAT Gateway is for outbound internet access from private subnets, not for private connectivity to AWS services like SQS.
