“Awareness & Training – AWS trains AWS employees, but a customer must train their own employees.”

#7. According to best practices, how should an application be designed to run in the AWS Cloud?

Loose Coupling

As application complexity increases, a desirable attribute of an IT system is that it can
be broken into smaller, loosely coupled components. This means that IT systems
should be designed in a way that reduces inter-dependencies —a change or a failure in
one component should not cascade to other components.

#14. Which of the following is characteristic of Amazon S3?

Amazon S3 also supports features that help maintain data version control, prevent accidental deletions, and replicate data to the same or different AWS Region. With S3 Versioning, you can easily preserve, retrieve, and restore every version of an object stored in Amazon S3, which allows you to recover from unintended user actions and application failures. To prevent accidental deletions, enable Multi-Factor Authentication (MFA) Delete on an S3 bucket. If you try to delete an object stored in an MFA Delete-enabled bucket, it will require two forms of authentication: your AWS account credentials and the concatenation of a valid serial number, a space, and the six-digit code displayed on an approved authentication device, like a hardware key fob or a Universal 2nd Factor (U2F) security key.

#15. What can you create in AWS to maintain a log of network connections?

AWS uses Flow Logs to log network connections and communications within the cloud.

#16. Which service enables risk auditing by continuously monitoring and logging account activity, including user actions in the AWS Management Console and AWS SDKs?

AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. CloudTrail provides event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services. This event history simplifies security analysis, resource change tracking, and troubleshooting. In addition, you can use CloudTrail to detect unusual activity in your AWS accounts. These capabilities help simplify operational analysis and troubleshooting.

#17. A characteristic of edge locations is that they:

If the content is already in the edge location with the lowest latency, CloudFront delivers it immediately.

If the content is not in that edge location, CloudFront retrieves it from an origin that you’ve defined—such as an Amazon S3 bucket, a MediaPackage channel, or an HTTP server (for example, a web server) that you have identified as the source for the definitive version of your content.

#18. What privilege is specific to the AWS root account, and cannot be granted to another IAM user on the account?

#19. Which AWS IAM feature allows developers to access AWS services through the AWS CLI?

(I’m not 100% sure about this answer)

#20. Which of the following can limit Amazon Storage Service (Amazon S3) bucket access to specific users?

Managing access refers to granting others (AWS accounts and users) permission to perform the resource operations by writing an access policy. For example, you can grant PUT Object permission to a user in an AWS account so the user can upload objects to your bucket. In addition to granting permissions to individual users and accounts, you can grant permissions to everyone (also referred as anonymous access) or to all authenticated users (users with AWS credentials). For example, if you configure your bucket as a website, you may want to make objects public by granting the GET Object permission to everyone.

#21. Which AWS tools assist with estimating costs?

You can use tags to organize your resources, and cost allocation tags to track your AWS costs on a detailed level. After you activate cost allocation tags, AWS uses the cost allocation tags to organize your resource costs on your cost allocation report, to make it easier for you to categorize and track your AWS costs.

#22. Compared with costs in traditional and virtualized data centers, AWS has:

#23. Which service should a customer use to consolidate and centrally manage multiple AWS accounts?

AWS Organizations helps you centrally govern your environment as you grow and scale your workloads on AWS.

#24. Under the AWS shared responsibility model, which of the following activities are the customer’s responsibility?

The AWS customer is the one in charge of the

#25. Which of the following is a correct relationship between regions, Availability Zones, and edge locations?

CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you’re serving with CloudFront, the user is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.

#26. Which of the Reserved Instance (RI) pricing models can change the attributes of the RI as long as the exchange results in the creation of RIs of equal or greater value?
