• Question 251:

  Which of the following are design principles for reliability in the AWS Cloud? (Choose two.)

  A. Build architectures with tightly coupled resources.
  B. Use AWS Trusted Advisor to meet security best practices.
  C. Use automation to recover immediately from failure.
  D. Right size Amazon EC2 instances to ensure optimal performance.
  E. Simulate failures to test recovery processes.
  C. Use automation to recover immediately from failure.
  E. Simulate failures to test recovery processes.

  Explanation/Reference:

  Manage change in automation: Changes to your infrastructure should be made using automation. The changes that need to be managed include changes to the automation, which then can be tracked and reviewed.

  Test recovery procedures: In an on-premises environment, testing is often conducted to prove that the workload works in a particular scenario. Testing is not typically used to validate recovery strategies. In the cloud, you can test how your workload fails, and you can validate your recovery procedures.

• Question 252:

  If a customer needs to audit the change management of AWS resources, which of the following AWS services should the customer use?

  A. AWS Config
  B. AWS Trusted Advisor
  C. Amazon CloudWatch
  D. Amazon Inspector
  A. AWS Config

  ---

  Explanation/Reference:

  AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. With Config, you can review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines. This enables you to simplify compliance auditing, security analysis, change management, and operational troubleshooting.
