Question 52

A security team is concerned that a developer can unintentionally attach an Elastic IP address to an Amazon EC2 instance in production. No developer should be allowed to attach an Elastic IP address to an instance. The security team must be notified if any production server has an Elastic IP address at any time

How can this task be automated'?

Options:

Use Amazon Athena to query AWS CloudTrail logs to check for any associate-address attempts Create an AWS Lambda function to disassociate the Elastic IP address from the instance, and alert the security team.

Attach an 1AM policy to the developers' 1AM group to deny associate-address permissions Create a custom AWS Config rule to check whether an Elastic IP address is associated with any instance tagged as production, and alert the security team

Ensure that all 1AM groups associated with developers do not have associate-address permissions. Create a scheduled AWS Lambda function to check whether an Elastic IP address is associated with any instance tagged as production, and alert the secunty team if an instance has an Elastic IP address associated with it

Create an AWS Config rule to check that all production instances have EC2 1AM roles that include deny associate-address permissions Verify whether there is an Elastic IP address associated with any instance, and alert the security team if an instance has an Elastic IP address associated with it.

Question 53

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)., ]

That's amazing. I think I'm going to give Cramkey Dumps a try for my next exam. Thanks for telling me about them! CramKey admin please share more questions……You guys are amazing.

Nate Sep 15, 2024

I failed last week, I never know this site , but amazed to see all these questions were in my exam week before. I feel bad now, why I didn’t bother this site. Thanks Cramkey, Excellent Job.

Nadia

Why these dumps are important? Can I pass my exam without these dumps?

Julian Oct 22, 2024

The questions in the Cramkey dumps are explained in detail and there are also study notes and reference materials provided. This made it easier for me to understand the concepts and retain the information better.

Aliza

I used these dumps for my recent certification exam and I can say with certainty that they're absolutely valid dumps. The questions were very similar to what came up in the actual exam.

Jakub Sep 22, 2024

That's great to hear. I am going to try them soon.

Madeleine

Passed my exam with my dream score…. Guys do give these dumps a try. They are authentic.

Ziggy Sep 3, 2024

That's really impressive. I think I might give Cramkey Dumps a try for my next certification exam.

Question 54

A company is building a web and mobile application that uses a serverless architecture powered by AWS Lambda and Amazon API Gateway The company wants to fully automate the backend Lambda deployment based on code that is pushed to the appropriate environment branch in an AWS CodeCommit repository

The deployment must have the following:

Question 55

A company is running a custom-built application that processes records. All the components run on Amazon EC2 instances that run in an Auto Scaling group. Each record's processing is a multistep sequential action that is compute-intensive. Each step is always completed in 5 minutes or less.

A limitation of the current system is that if any steps fail, the application has to reprocess the record from the beginning The company wants to update the architecture so that the application must reprocess only the failed steps.

What is the MOST operationally efficient solution that meets these requirements?

Options:

Create a web application to write records to Amazon S3 Use S3 Event Notifications to publish to an Amazon Simple Notification Service (Amazon SNS) topic Use an EC2 instance to poll Amazon SNS and start processing Save intermediate results to Amazon S3 to pass on to the next step

Perform the processing steps by using logic in the application. Convert the application code to run in a container. Use AWS Fargate to manage the container Instances. Configure the container to invoke itself to pass the state from one step to the next.

Create a web application to pass records to an Amazon Kinesis data stream. Decouple the processing by using the Kinesis data stream and AWS Lambda functions.

Create a web application to pass records to AWS Step Functions. Decouple the processing into Step Functions tasks and AWS Lambda functions.
