AWS Certified Solutions Architect – Professional — Question 446

Which statement is NOT true about a stack which has been created in a Virtual Private Cloud (VPC) in AWS OpsWorks?

Answer options

• A. Subnets whose instances cannot communicate with the Internet are referred to as public subnets.
• B. Subnets whose instances can communicate only with other instances in the VPC and cannot communicate directly with the Internet are referred to as private subnets.
• C. All instances in the stack should have access to any package repositories that your operating system depends on, such as the Amazon Linux or Ubuntu Linux repositories.
• D. Your app and custom cookbook repositories should be accessible for all instances in the stack.

Correct answer: A

Explanation

Option A is incorrect (and thus the correct answer) because subnets that lack direct communication with the Internet are defined as private subnets, whereas public subnets have routes to an Internet Gateway. AWS OpsWorks instances, whether in public or private subnets, must still be able to access OS package repositories as well as custom cookbook and application repositories to provision successfully.
