A company wants to deploy and maintain static websites on AWS. Each website's source code is hosted in one of several version control systems, including AWS CodeCommit, Bitbucket, and GitHub.
The company wants to implement phased releases by using development, staging, user acceptance testing, and production environments in the AWS Cloud. Deployments to each environment must be started by code merges on the relevant Git branch. The company wants to use HTTPS for all data exchange. The company needs a solution that does not require servers to run continuously.
Which solution will meet these requirements with the LEAST operational overhead?

• A.  Host each website in different Amazon S3 buckets for each environment. Configure AWS CodePipeline to pull source code from version control. Add an AWS CodeBuild stage to copy source code to Amazon S3.
• B.  Host each website by using AWS Amplify with a serverless backend. Conned the repository branches that correspond to each of the desired environments. Start deployments by merging code changes to a desired branch.
• C.  Host each website on its own Amazon EC2 instance. Write a custom deployment script to bundle each website's static assets. Copy the assets to Amazon EC2. Set up a workflow to run the script when code is merged.
• D.  Host each website in AWS Elastic Beanstalk with multiple environments. Use the EB CLI to link each repository branch. Integrate AWS CodePipeline to automate deployments from version control code merges.

A company hosts its application on AWS. The application runs on an Amazon Elastic Container Service (Amazon ECS) cluster that uses AWS Fargate. The cluster runs behind an Application Load Balancer The application stores data in an Amazon Aurora database A developer encrypts and manages database credentials inside the application The company wants to use a more secure credential storage method and implement periodic credential rotation.
Which solution will meet these requirements with the LEAST operational overhead?

• A.  Migrate the credentials to AWS Secrets Manager. Encrypt the credentials by using an AWS Key Management Service (AWS KMS) key Turn on secret rotation Use 1AM policies and roles to grant Amazon ECS Fargate permissions to access to AWS Secrets Manager by using keys.
• B.  Migrate the credentials to AWS Systems Manager Parameter Store. Encrypt the parameter by using an AWS Key Management Service (AWS KMS) key. Turn on secret rotation. Use 1AM policies and roles to grant Amazon ECS Fargate permissions to access to AWS Secrets Manager
• C.  Migrate the secret credentials to Amazon RDS parameter groups. Encrypt the parameter by using an AWS Key Management Service (AWS KMS) key Turn on secret rotation. Use 1AM policies and roles to grant AWS KMS permissions to access Amazon RDS.
• D.  Migrate the credentials to ECS Fargate environment variables. Encrypt the credentials by using an AWS Key Management Service (AWS KMS) key Turn on secret rotation. Use 1AM policies and roles to grant Amazon ECS Fargate permissions to access to AWS Secrets Manager.

A developer is working on an app for a company that uses an Amazon DynamoDB table named Orders to store customer orders. The table uses OrderlD as the partition key and there is no sort key. The table contains more than 100,000 records. The developer needs to add a functionality that will retrieve all Orders records that contain an OrderSource attribute with the MobileApp value.
Which solution will improve the user experience in the MOST efficient way?

• A.  Create a global secondary index (GSI) with OrderSource as the sort key. Perform a Query operation by using MobileApp as the key.
• B.  Create a local secondary index (LSI) with OrderSource as the partition key. Perform a Query operation by using MobileApp as the key.
• C.  Create a global secondary index (GSI) with OrderSource as the partition key. Perform a Query operation by using MobileApp as the key.
• D.  Perform a Scan operation on the Orders table. Provide a QueryFilter condition to filter to only the items where the OrderSource attribute is equal to the MobileApp value.

A developer is setting up infrastructure by using AWS Cloud Formation. If an error occurs when the resources described in the CloudFormation template are provisioned, successfully provisioned resources must be preserved. The developer must provision and update the CloudFormation stack by using the AWS CLI.
Which solution will meet these requirements?

• A.  Add an --enable-terminal ion-protection command line option to the create-stack command and the update-stack command.
• B.  Add a -parameters ParameterKey=P reserve Resources. ParameterVaIue=True command line option to the create-stack command and the update-stack command.
• C.  Add a -disable-roll back command line option to the create-stack command and the update-stack command
• D.  Add a -tags Key=PreserveResources.VaIue=True command line option to the create-stack command and the update-stack command.

A company is providing read access to objects in an Amazon S3 bucket for different customers. The company uses 1AM permissions to restrict access to the S3 bucket. The customers can access only their own files.
Due to a regulation requirement, the company needs to enforce encryption in transit for interactions with Amazon S3.
Which solution will meet these requirements?

• A.  Add an 1AM policy to the 1AM users that allows S3 actions when the s3:x-amz-acl condition is equal to bucket-owner-read.
• B.  Add a bucket policy to the S3 bucket to deny S3 actions when the s3:x-amz-acl condition is equal to public-read.
• C.  Add a bucket policy to the S3 bucket to deny S3 actions when the aws:SecureTransport condition is equal to false.
• D.  Add an 1AM policy to the 1AM users to enforce the usage of the AWS SDK.
