  6. Which AWS service enables you to decouple application components using a publish/subscribe messaging pattern?

    Answer: Amazon SNS

    Amazon SNS is a pub/sub messaging service that allows publishers to send messages to topics, which fan out to multiple subscribers simultaneously.

  7. What does 'infrastructure as code' mean in the context of AWS architecture best practices?

    Answer: Defining and managing cloud infrastructure using configuration files and templates

    Infrastructure as code means defining your infrastructure in configuration files (like CloudFormation templates) so it can be version-controlled, tested, and repeatedly deployed.
