Question

A network engineer has deployed an Amazon EC2 instance in a private subnet in a VPC. The VPC has no public subnet. The EC2 instance hosts application code that sends messages to an Amazon Simple Queue Service (Amazon SQS) queue. The subnet has the default network ACL with no modification applied. The EC2 instance has the default security group with no modification applied. The SQS queue is not receiving messages. Which of the following are possible causes of this problem? (Choose two.)

Accepted Answer

Correct answer: A, C. The correct answer is A, C. Option A: The EC2 instance is not attached to an IAM role that allows write operations to Amazon SQS. Option C: There is no interface VPC endpoint configured for Amazon SQS Amazon EC2 provides resizable virtual servers when you need full control of the operating system. A VPC endpoint provides private connectivity to AWS services without traversing the public internet. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes.
