• Question 385:

  Which statements explain the business value of migration to the AWS Cloud? (Select TWO.)

  A. The migration of enterprise applications to the AWS Cloud makes these applications automatically available on mobile devices.
  B. AWS availability and security provide the ability to improve service level agreements (SLAs) while reducing risk and unplanned downtime.
  C. Companies that migrate to the AWS Cloud eliminate the need to plan for high availability and disaster recovery.
  D. Companies that migrate to the AWS Cloud reduce IT costs related to infrastructure, freeing budget for reinvestment in other areas.
  E. Applications are modernized because migration to the AWS Cloud requires companies to rearchitect and rewrite all enterprise applications.
  B. AWS availability and security provide the ability to improve service level agreements (SLAs) while reducing risk and unplanned downtime.
  D. Companies that migrate to the AWS Cloud reduce IT costs related to infrastructure, freeing budget for reinvestment in other areas.

  ---

  Explanation

  B and D are correct because AWS availability and security enable customers to improve their SLAs while reducing risk and unplanned downtime1, and AWS reduces IT costs related to infrastructure, allowing customers to reinvest in other areas2. A is incorrect because migrating to the AWS Cloud does not automatically make applications available on mobile devices, as it depends on the application design and compatibility. C is incorrect because companies that migrate to the AWS Cloud still need to plan for high availability and disaster recovery, as AWS is a shared responsibility model3. E is incorrect because migrating to the AWS Cloud does not require companies to rearchitect and rewrite all enterprise applications, as AWS offers different migration strategies depending on the application complexity and business objectives4.

• Question 386:

• Question 387:

  A company wants to store its files in the AWS Cloud. Users need to be able to download these files directly using a public URL.

  Which AWS service or feature will meet this requirement?

  A. Amazon Redshift
  B. Amazon Elastic Block Store (Amazon EBS)
  C. Amazon Elastic File System (Amazon EFS)
  D. Amazon S3
  D. Amazon S3

  ---

  Explanation

  Amazon S3 (Simple Storage Service) is a scalable object storage service that allows users to store and retrieve any amount of data at any time from anywhere on the web. S3 provides the ability to make objects (files) publicly accessible via a

  public URL, which allows users to download files directly. S3 is highly durable, scalable, and secure, making it an ideal service for storing files that need to be accessed publicly.

  Why other options are not suitable:

  A. Amazon Redshift: A data warehouse service designed for complex queries and analytics, not for storing and publicly sharing files.

  B. Amazon Elastic Block Store (Amazon EBS): Provides block storage for use with EC2 instances, but does not support public URLs or direct file access from the web.

  C. Amazon Elastic File System (Amazon EFS): A managed file storage service for use with EC2 instances, not designed for public access via URLs.

• Question 388:

  A company is planning to migrate its application to the AWS Cloud.

  Which AWS tool or set of resources should the company use to analyze and assess its readiness for migration?

  A. AWS Cloud Adoption Framework (AWS CAF)
  B. AWS Pricing Calculator
  C. AWS Well-Architected Framework
  D. AWS Budgets

  The AWS Cloud Adoption Framework (AWS CAF) is indeed designed to help organizations develop an effective strategy for adopting the AWS Cloud. It provides guidance on key aspects of cloud adoption, including business, people, governance, and technology considerations. While the AWS CAF does not directly offer a tool for analyzing readiness for migration, it does provide a comprehensive framework that can help organizations assess their readiness and plan their migration strategy effectively.
