  ---

  Explanation

  Some of the advantages of using Amazon EC2 instances to host applications in the AWS Cloud instead of on premises are:

  EC2 integrates with Amazon VPC, AWS CloudTrail, and AWS Identity and Access Management (IAM). Amazon VPC lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network

  that you define. AWS CloudTrail enables governance, compliance, operational auditing, and risk auditing of your AWS account. AWS IAM enables you to manage access to AWS services and resources securely. Therefore, the correct

  answer is

  B. You can learn more about Amazon EC2 and its integration with other AWS services from this page.

  EC2 has a flexible, pay-as-you-go pricing model. You only pay for the compute capacity you use, and you can scale up and down as needed. You can also choose from different pricing options, such as On-Demand, Savings Plans, Reserved

  Instances, and Spot Instances, to optimize your costs. Therefore, the correct answer is

  D. You can learn more about Amazon EC2 pricing from this page.

  The other options are incorrect because:

  EC2 does not include operating system patch management. You are responsible for managing and maintaining your own operating systems on EC2 instances. You can use AWS Systems Manager to automate common maintenance tasks,

  such as applying patches, or use Amazon EC2 Image Builder to create and maintain secure images. Therefore, the incorrect answer is A. EC2 does not have a 100% service level agreement (SLA). The EC2 SLA guarantees 99.99%

  availability for each EC2 Region, not for each individual instance. Therefore, the incorrect answer is

  C.

  EC2 does not have automatic storage cost optimization. You are responsible for choosing the right storage option for your EC2 instances, such as Amazon Elastic Block Store (EBS) or Amazon Elastic File System (EFS), and monitoring and

  optimizing your storage costs. You can use AWS Cost Explorer or AWS Trusted Advisor to analyze and reduce your storage spending. Therefore, the incorrect answer is

  E.

• Question 563:

  Which AWS service or feature requires an internet service provider (ISP) and a colocation facility to be implemented?

  A. AWS VPN
  B. Amazon Connect
  C. AWS Direct Connect
  D. Internet gateway
  C. AWS Direct Connect

  ---

  Explanation

  AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. This requires the use of an Internet Service Provider (ISP) and a colocation facility to connect to the Direct Connect location. It provides a private, high-speed, low-latency connection that does not go over the public internet.

  A. AWS VPN: Incorrect, as AWS VPN establishes secure connections over the internet and does not necessarily require a colocation facility.

  B. Amazon Connect: Incorrect, as it is a cloud-based contact center service.

  D. Internet Gateway: Incorrect, as it is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet.

• Question 564:

  Which of the following are pillars of the AWS Well-Architected Framework? (Choose two.)

  A. High availability
  B. Performance efficiency
  C. Cost optimization
  D. Going global in minutes
  E. Continuous development
  B. Performance efficiency
  C. Cost optimization

  ---

  Explanation

  The AWS Well-Architected Framework is a set of six pillars and lenses that help cloud architects design and run workloads in the cloud. The six pillars are: operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability. Each pillar has a set of design principles and best practices that guide the architectural decisions. High availability is not a separate pillar, but a quality that can be achieved by applying the principles of the reliability pillar. Going global in minutes and continuous development are not pillars of the framework, but possible benefits of using AWS services and following the framework's recommendations.

• Question 565:

  Which AWS services are supported by Savings Plans? (Select TWO.)

  A. Amazon EC2
  B. Amazon RDS
  C. Amazon SageMaker
  D. Amazon Redshift
  E. Amazon DynamoDB
  A. Amazon EC2
  C. Amazon SageMaker

  ---

  Explanation

  The AWS services that are supported by Savings Plans are:

  Amazon EC2: Amazon EC2 is a service that provides scalable computing capacity in the AWS cloud. You can use Amazon EC2 to launch virtual servers, configure security and networking, and manage storage. Amazon EC2 is eligible for

  both Compute Savings Plans and EC2 Instance Savings Plans12. Amazon SageMaker: Amazon SageMaker is a service that helps you build and deploy machine learning models. You can use Amazon SageMaker to access Jupyter

  notebooks, use common machine learning algorithms, train and tune models, and deploy them to a hosted environment. Amazon SageMaker is eligible for SageMaker Savings Plans13. The other options are not supported by Savings Plans.

  Amazon RDS, Amazon Redshift, and Amazon DynamoDB are database services that are eligible for Reserved Instances, but not Savings Plans4.

• Question 566:

• Question 567:

  A newly created IAM user has no IAM policy attached.

  What will happen when the user logs in and attempts to view the AWS resources in the account?

  A. All AWS services will be read-only access by default.
  B. Access to all AWS resources will be denied.
  C. Access to the AWS billing services will be allowed.
  D. Access to AWS resources will be allowed through the AWS CLL
  B. Access to all AWS resources will be denied.

  ---

  Explanation

  Access to all AWS resources will be denied if a newly created IAM user has no IAM policy attached and logs in and attempts to view the AWS resources in the account. IAM policies are the way to grant permissions to IAM users, groups, and roles to access and manage AWS resources. By default, IAM users have no permissions, unless they are explicitly granted by an IAM policy. Therefore, a newly created IAM user without any IAM policy attached will not be able to view or perform any actions on the AWS resources in the account. Access to the AWS billing services and AWS CLI will also be denied, unless the user has the necessary permissions.

• Question 568:

  A company is planning to migrate a monolithic application to AWS. The company wants to modernize the application by splitting it into microservices. The company will deploy the microservices on AWS. Which migration strategy should the company use?

  A. Rehost
  B. Repurchase
  C. Replatform
  D. Refactor
  D. Refactor

  ---

  Explanation

  Refactoring involves re-architecting and modifying an application to take advantage of cloud-native features. In this case, the company wants to modernize a monolithic application by breaking it into microservices. This process aligns with the Refactor strategy, which is aimed at modernizing and re-architecting applications. Rehost, Repurchase, and Replatform do not involve the level of re-architecting needed to move from a monolithic to a microservices architecture.

• Question 570:

  A company wants to build a new web application by using AWS services. The application must meet the on-demand load for periods of heavy activity.

  Which AWS services or resources provide the necessary workload adjustments to meet these requirements? (Select TWO.)

  A. Amazon Machine Image (AMI)
  B. Amazon EC2 Auto Scaling
  C. Amazon EC2 instance
  D. AWS Lambda
  E. EC2 Image Builder
  B. Amazon EC2 Auto Scaling
  D. AWS Lambda

  ---

  Explanation

  Amazon EC2 Auto Scaling helps you ensure that you have the correct number of Amazon EC2 instances available to handle the load for your application. You create collections of EC2 instances, called Auto Scaling groups. You can specify the minimum number of instances in each Auto Scaling group, and Amazon EC2 Auto Scaling ensures that your group never goes below this size. You can specify the maximum number of instances in each Auto Scaling group, and Amazon EC2 Auto Scaling ensures that your group never goes above this size4. AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.
