  A company needs to migrate all of its development teams to a cloud-based integrated development environment (IDE).

  Which AWS service should the company use?

  A. AWS CodeBuild
  B. AWS Cloud9
  C. AWS OpsWorks
  D. AWS Cloud Development Kit (AWS CDK)
  B. AWS Cloud9

  ---

  Explanation

  The correct answer is B because AWS Cloud9 is an AWS service that enables users to run their existing custom, nonproduction workloads in the AWS Cloud quickly and cost-effectively. AWS Cloud9 is a cloud-based integrated development environment (IDE) that allows users to write, run, and debug code from a web browser. AWS Cloud9 supports multiple programming languages, such as Python, Java, Node.js, and more. AWS Cloud9 also provides users with a terminal that can access AWS services and resources, such as Amazon EC2 instances, AWS Lambda functions, and AWS CloudFormation stacks. The other options are incorrect because they are not AWS services that enable users to run their existing custom, nonproduction workloads in the AWS Cloud quickly and cost-effectively. AWS CodeBuild is an AWS service that enables users to compile, test, and package their code for deployment. AWS OpsWorks is an AWS service that enables users to configure and manage their applications using Chef or Puppet. AWS Cloud Development Kit (AWS CDK) is an AWS service that enables users to define and provision their cloud infrastructure using familiar programming languages, such as TypeScript, Python, Java, and C#.

  AWS Cloud9 FAQs

• Question 717:

  A company has an application that runs periodically in an on-premises environment. The application runs for a few hours most days, but runs for 8 hours a day for a week at the end of each month.

  Which AWS service or feature should be used to host the application in the AWS Cloud?

  A. Amazon EC2 Standard Reserved Instances
  B. Amazon EC2 On-Demand Instances
  C. AWS Wavelength
  D. Application Load Balancer
  B. Amazon EC2 On-Demand Instances

  ---

  Explanation

  Amazon EC2 On-Demand Instances are instances that let you pay for compute capacity by the hour or second (minimum of 60 seconds) with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs. On-Demand Instances are suitable for applications with short-term, irregular, or unpredictable workloads that cannot be interrupted, such as periodic applications that run for a few hours most days, but run for 8 hours a day for a week at the end of each month2. Amazon EC2 Standard Reserved Instances are instances that provide you with a significant discount (up to 75%) compared to On-Demand Instance pricing. In exchange, you select a term and make an upfront payment to reserve a certain amount of compute capacity for that term. Reserved Instances are suitable for applications with steady state or predictable usage that require reserved capacity3. AWS Wavelength is a service that enables developers to build applications that deliver ultra-low latency to mobile devices and users by deploying AWS compute and storage at the edge of the 5G network. Wavelength is suitable for applications that require single-digit millisecond latencies, such as game and live video streaming, machine learning inference at the edge, and augmented and virtual reality (AR/VR). Application Load Balancer is a service that operates at the request level (layer 7) and distributes incoming application traffic across multiple targets, such as EC2 instances, containers, Lambda functions, and IP addresses. Application Load Balancer is suitable for applications that need advanced routing capabilities, such as microservices or container-based architectures.

• Question 718:

  A company is looking for a managed machine learning (ML) service that can recommend products based on a customer's previous behaviors.

  Which AWS service meets this requirement?

  A. Amazon Personalize
  B. Amazon SageMaker
  C. Amazon Pinpoint
  D. Amazon Comprehend
  A. Amazon Personalize

  ---

  Explanation

  The AWS service that meets the requirement of providing a managed machine learning (ML) service that can recommend products based on a customer's previous behaviors is Amazon Personalize. Amazon Personalize is a fully managed service that enables developers to create personalized recommendations for customers using their own data. Amazon Personalize can automatically process and examine the data, identify what is meaningful, select the right algorithms, and train and optimize a personalized recommendation model2. Amazon SageMaker, Amazon Pinpoint, and Amazon Comprehend are other AWS services related to machine learning, but they do not provide the specific functionality of product recommendation.

• Question 719:

  A company wants to improve its security and audit posture by limiting Amazon EC2 inbound access.

  According to the AWS shared responsibility model, which task is the responsibility of the customer?

  A. Protect the global infrastructure that runs all of the services offered in the AWS Cloud.
  B. Configure logical access controls for resources, and protect account credentials.
  C. Configure the security used by managed services.
  D. Patch and back up Amazon Aurora.
  B. Configure logical access controls for resources, and protect account credentials.

  ---

  Explanation

  According to the AWS shared responsibility model, the customer is responsible for configuring logical access controls for resources, and protecting account credentials. This includes managing IAM user permissions, security group rules, network ACLs, encryption keys, and other aspects of access management1. AWS is responsible for protecting the global infrastructure that runs all of the services offered in the AWS Cloud, such as the hardware, software, networking, and facilities. AWS is also responsible for configuring the security used by managed services, such as Amazon RDS, Amazon DynamoDB, and Amazon Aurora2.

Amazon SNS is a fully managed pub/sub messaging service that enables the user to send messages to multiple subscribers or endpoints, such as email addresses, phone numbers, HTTP endpoints, AWS Lambda functions, and more. Amazon SNS can be used to send notifications, alerts, confirmations, and reminders from applications to users or other applications4.
