Question 1

A company has an application that includes AWS Lambda functions. The Lambda functions run Python code that is stored in an AWS CodeCommit repository. The company has recently experienced failures in the production environment because of an error in the Python code. An engineer has written unit tests for the Lambda functions to help avoid releasing any future defects into the production environment.

The company's DevOps team needs to implement a solution to integrate the unit tests into an existing AWS CodePipeline pipeline. The solution must produce reports about the unit tests for the company to view.

Which solution will meet these requirements?

Options:

Associate the CodeCommit repository with Amazon CodeGuru Reviewer. Create a new AWS CodeBuild project. In the CodePipeline pipeline, configure a test stage that uses the new CodeBuild project. Create a buildspec.yml file in the CodeCommit repository. In the buildspec.yml file, define the actions to run a CodeGuru review.

Create a new AWS CodeBuild project. In the CodePipeline pipeline, configure a test stage that uses the new CodeBuild project. Create a CodeBuild report group. Create a buildspec.yml file in the CodeCommit repository. In the buildspec.yml file, define the actions to run the unit tests with an output of JUNITXML in the build phase section. Configure the test reports to be uploaded to the new CodeBuild report group.

Create a new AWS CodeArtifact repository. Create a new AWS CodeBuild project. In the CodePipeline pipeline, configure a test stage that uses the new CodeBuild project. Create an appspec.yml file in the original CodeCommit repository. In the appspec.yml file, define the actions to run the unit tests with an output of CUCUMBERJSON in the build phase section. Configure the tests reports to be sent to the new CodeArtifact repository.

Create a new AWS CodeBuild project. In the CodePipeline pipeline, configure a test stage that uses the new CodeBuild project. Create a new Amazon S3 bucket. Create a buildspec.yml file in the CodeCommit repository. In the buildspec.yml file, define the actions to run the unit tests with an output of HTML in the phases section. In the reports section, upload the test reports to the S3 bucket.

Question 2

A company has an application that stores data that includes personally Identifiable Information (Pll) In an Amazon S3 bucket All data Is encrypted with AWS Key Management Service (AWS KMS) customer managed keys. All AWS resources are deployed from an AWS Cloud Formation template.

A DevOps engineer needs to set up a development environment for the application in a different AWS account The data in the development environment's S3 bucket needs to be updated once a week from the production environment's S3 bucket.

The company must not move Pll from the production environment without anonymizmg the Pll first The data in each environment must be encrypted with different KMS customer managed keys.

Which combination of steps should the DevOps engineer take to meet these requirements? (Select TWO )

Options:

Activate Amazon Macie on the S3 bucket In the production account Create an AWS Step Functions state machine to initiate a discovery job and redact all Pll before copying files to the S3 bucket in the development account. Give the state machine tasks decrypt permissions on the KMS key in the production account. Give the state machine tasks encrypt permissions on the KMS key in the development account

Set up S3 replication between the production S3 bucket and the development S3 bucket Activate Amazon Macie on the development S3 bucket Create an AWS Step Functions state machine to initiate a discovery job and redact all Pll as the files are copied to the development S3 bucket. Give the state machine tasks encrypt and decrypt permissions on the KMS key in the development account.

Set up an S3 Batch Operations job to copy files from the production S3 bucket to the development S3 bucket. In the development account, configure an

AWS Lambda function to redact all Pll. Configure S3 Object Lambda to use the Lambda function for S3 GET requests Give the Lambda function's 1AM role encrypt and decrypt permissions on the KMS key in the development account.

Create a development environment from the CloudFormatlon template in the development account. Schedule an Amazon EventBridge rule to start the AWS Step Functions state machine once a week

Create a development environment from the CloudFormation template in the development account. Schedule a cron job on an Amazon EC2 instance to run once a week to start the S3 Batch Operations job.

Question 3

A company is refactoring applications to use AWS. The company identifies an internal web application that needs to make Amazon S3 API calls in a specific AWS account.

The company wants to use its existing identity provider (IdP) auth.company.com for authentication. The IdP supports only OpenID Connect (OIDC). A DevOps engineer needs to secure the web application's access to the AWS account.

Which combination of steps will meet these requirements? (Select THREE.)

Options:

Configure AWS 1AM Identity Center. Configure an IdP. Upload the IdP metadata from the existing IdP.

Create an 1AM IdP by using the provider URL, audience, and signature from the existing IdP.

Create an 1AM role that has a policy that allows the necessary S3 actions. Configure the role's trust policy to allow the OIDC IdP to assume the role if the sts.amazon.conraud context key is appid from idp.

Create an 1AM role that has a policy that allows the necessary S3 actions. Configure the role's trust policy to allow the OIDC IdP to assume the role if the auth.company.com:aud context key is appid_from_idp.

Configure the web application lo use the AssumeRoleWith Web Identity API operation to retrieve temporary credentials. Use the temporary credentials to make the S3 API calls.

Configure the web application to use the GetFederationToken API operation to retrieve temporary credentials Use the temporary credentials to make the S3 API calls.

Answer:

B, D, E

Explanation:

Step 1: Creating an Identity Provider in IAMYou first need to configure AWS to trust the external identity provider (IdP), which in this case supports OpenID Connect (OIDC). The IdP will handle the authentication, and AWS will handle the authorization based on the IdP's token.

Action:Create an IAM Identity Provider (IdP) in AWS using the existing provider's URL, audience, and signature. This step is essential for establishing trust between AWS and the external IdP.

Why:This allows AWS to accept tokens from your external IdP (auth.company.com) for authentication.

[Reference:AWS documentation onIAM Identity Providers., So, this corresponds toOption B: Create an IAM IdP by using the provider URL, audience, and signature from the existing IdP., Step 2: Creating an IAM Role with Specific PermissionsNext, you need to create an IAM role with a trust policy that allows the external IdP to assume it when certain conditions are met. Specifically, the trust policy needs to allow the role to be assumed based on the context key auth.company.com:aud (audience claim in the token)., Action:Create an IAM role that has the necessary permissions (e.g., Amazon S3 access). The role's trust policy should specify the OIDC IdP as the trusted entity and validate the audience claim (auth.company.com:aud), which comes from the token provided by the IdP., Why:This step ensures that only the specified web application authenticated via OIDC can assume the IAM role to make API calls., Reference:AWS documentation onOIDC and Role Assumption., This corresponds toOption D: Create an IAM role that has a policy that allows the necessary S3 actions. Configure the role's trust policy to allow the OIDC IdP to assume the role if the auth.company.com:aud context key is appid_from_idp., Step 3: Using Temporary Credentials via AssumeRoleWithWebIdentity APITo securely make Amazon S3 API calls, the web application will need temporary credentials. The web application can use the AssumeRoleWithWebIdentity API call to assume the IAM role configured in the previous step and obtain temporary AWS credentials. These credentials can then be used to interact with Amazon S3., Action:The web application must be configured to call the AssumeRoleWithWebIdentity API operation, passing the OIDC token from the IdP to obtain temporary credentials., Why:This allows the web application to authenticate via the external IdP and then authorize access to AWS resources securely using short-lived credentials., Reference:AWS documentation onAssumeRoleWithWebIdentity., This corresponds toOption E: Configure the web application to use the AssumeRoleWithWebIdentity API operation to retrieve temporary credentials. Use the temporary credentials to make the S3 API calls., Summary of Selected Answers:, B: Create an IAM IdP by using the provider URL, audience, and signature from the existing IdP., D: Create an IAM role that has a policy that allows the necessary S3 actions. Configure the role’s trust policy to allow the OIDC IdP to assume the role if the auth.company.com:aud context key is appid_from_idp., E: Configure the web application to use the AssumeRoleWithWebIdentity API operation to retrieve temporary credentials. Use the temporary credentials to make the S3 API calls., This setup enables the web application to use OpenID Connect (OIDC) for authentication and securely interact with Amazon S3 in a specific AWS account using short-lived credentials obtained through AWS Security Token Service (STS)., ]
