• Question 1212:

  A company is launching an application in the AWS Cloud. The application will use Amazon S3 storage. A large team of researchers will have shared access to the data. The company must be able to recover data that is accidentally

  overwritten or deleted.

  Which S3 feature should the company turn on to meet this requirement?

  A. Server access logging
  B. S3 Versioning
  C. S3 Lifecycle rules
  D. Encryption in transit and at rest
  B. S3 Versioning

  ---

  Explanation/Reference:

  Versioning-enabled buckets can help you recover objects from accidental deletion or overwrite. For example, if you delete an object, Amazon S3 inserts a delete marker instead of removing the object permanently. The delete marker becomes the current object version. If you overwrite an object, it results in a new object version in the bucket. You can always restore the previous version.

• Question 1213:

• Question 1215:

  A company wants to reduce the physical compute footprint that developers use to run code. Which service would meet that need by enabling serverless architectures?

  A. Amazon Elastic Compute Cloud (Amazon EC2)
  B. AWS Lambda
  C. Amazon DynamoDB
  D. AWS CodeCommit
  B. AWS Lambda

  ---

  Explanation/Reference:

  AWS Lambda is an integral part of coding on AWS. It reduces physical compute footprint by utilizing aws cloud services to run code.

• Question 1216:

  A company is planning to replace its physical on-premises compute servers with AWS serverless compute services. The company wants to be able to take advantage of advanced technologies quickly after the migration. Which pillar of the AWS Well-Architected Framework does this plan represent?

  A. Security
  B. Performance efficiency
  C. Operational excellence
  D. Reliability
  B. Performance efficiency

  ---

  Explanation/Reference:

  Performance efficiency: The performance efficiency pillar focuses on the efficient use of computing resources to meet requirements, and how to maintain efficiency as demand changes and technologies evolve.

  Operational Excellence: The operational excellence pillar includes how your organization supports your business objectives, your ability to run workloads effectively, gain insight into their operations, and to continuously improve supporting

  processes and procedures to deliver business value.

  I understand why you could think it is C, but I believe the correct answer is B (key part: as demand changes and technologies evolve)

• Question 1217:

  An ecommerce company manages its application's infrastructure by using AWS Elastic Beanstalk. A developer wants to deploy the new version of the application with the least possible application downtime. The developer also must minimize

  the application's rollback time if there are issues with the deployment.

  Which approach will meet these requirements?

  A. Use a rolling deployment to deploy the new version
  B. Use a rolling deployment with additional batches to deploy the new version
  C. Use an all-at-once deployment to deploy the new version
  D. Deploy the new version to a new environment Use a blue/green deployment
  D. Deploy the new version to a new environment Use a blue/green deployment

• Question 1218:

  Which of the following is a benefit of operating in the AWS Cloud?

  A. The ability to migrate on-premises network devices to the AWS Cloud
  B. The ability to expand compute, storage, and memory when needed
  C. The ability to host custom hardware in the AWS Cloud
  D. The ability to customize the underlying hypervisor layer for Amazon EC2
  B. The ability to expand compute, storage, and memory when needed

  ---

  Explanation/Reference:

  B. The ability to expand compute, storage, and memory when needed: One of the main benefits of operating in the AWS Cloud is the ability to rapidly scale your resources up or down as your needs change. With AWS, you can quickly provision new resources such as EC2 instances, databases, and storage to handle changing workloads or spikes in traffic. You can also scale resources automatically using services like AWS Auto Scaling, which automatically adjusts the number of EC2 instances in response to changes in demand.
