Question 49

A security engineer configures Amazon S3 Cross-Region Replication (CRR) for all objects that are in an S3 bucket in the us-east-1. Region Some objects in this S3 bucket use server-side encryption with AWS KMS keys (SSE-KMS) for encryption at test. The security engineer creates a destination S3 bucket in the us-west-2 Region. The destination S3 bucket is in the same AWS account as the source S3 bucket.

The security engineer also creates a customer managed key in us-west-2 to encrypt objects at rest in the destination S3 bucket. The replication configuration is set to use the key in us-west-2 to encrypt objects in the destination S3 bucket. The security engineer has provided the S3 replication configuration with an IAM role to perform the replication in Amazon S3.

After a day, the security engineer notices that no encrypted objects from the source S3 bucket are replicated to the destination S3 bucket. However, all the unencrypted objects are replicated.

Which combination of steps should the security engineer take to remediate this issue? (Select THREE.)

Options:

Change the replication configuration to use the key in us-east-1 to encrypt the objects that are in the destination S3 bucket.

Grant the IAM role the kms. Encrypt permission for the key in us-east-1 that encrypts source objects.

Grant the IAM role the s3 GetObjectVersionForReplication permission for objects that are in the source S3 bucket.

Grant the IAM role the kms. Decrypt permission for the key in us-east-1 that encrypts source objects.

Change the key policy of the key in us-east-1 to grant the kms. Decrypt permission to the security engineer's IAM account.

Grant the IAM role the kms Encrypt permission for the key in us-west-2 that encrypts objects that are in the destination S3 bucket.

Question 50

A company has an AWS account that hosts a production application. The company receives an email notification that Amazon GuardDuty has detected an Impact:lAMUser/AnomalousBehavior finding in the account. A security engineer needs to run the investigation playbook for this security incident and must collect and analyze the information without affecting the application.

Which solution will meet these requirements MOST quickly?

Options:

Log in to the AWS account by using read-only credentials. Review the GuardDuty finding for details about the IAM credentials that were used. Use the IAM console to add a DenyAll policy to the IAM principal.

Log in to the AWS account by using read-only credentials. Review the GuardDuty finding to determine which API calls initiated the finding. Use Amazon Detective to review the API calls in context.

Log in to the AWS account by using administrator credentials. Review the GuardDuty finding for details about the IAM credentials that were used. Use the IAM console to add a DenyAll policy to the IAM principal.

Log in to the AWS account by using read-only credentials. Review the GuardDuty finding to determine which API calls initiated the finding. Use AWS CloudTrail Insights and AWS CloudTrail Lake to review the API calls in context.

Question 51

A company in France uses Amazon Cognito with the Cognito Hosted Ul as an identity broker for sign-in and sign-up processes. The company is marketing an application and expects that all the application's users will come from France.

When the company launches the application the company's security team observes fraudulent sign-ups for the application. Most of the fraudulent registrations are from users outside of France.

The security team needs a solution to perform custom validation at sign-up Based on the results of the validation the solution must accept or deny the registration request.

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

Options:

Create a pre sign-up AWS Lambda trigger. Associate the Amazon Cognito function with the Amazon Cognito user pool.

Use a geographic match rule statement to configure an AWS WAF web ACL. Associate the web ACL with the Amazon Cognito user pool.

Configure an app client for the application's Amazon Cognito user pool. Use the app client ID to validate the requests in the hosted Ul.

Update the application's Amazon Cognito user pool to configure a geographic restriction setting.

Use Amazon Cognito to configure a social identity provider (IdP) to validate the requests on the hosted Ul.

Question 52

You have an S3 bucket defined in IAM. You want to ensure that you encrypt the data before sending it across the wire. What is the best way to achieve this.

Please select:

Options:

Enable server side encryption for the S3 bucket. This request will ensure that the data is encrypted first.

Use the IAM Encryption CLI to encrypt the data first

Use a Lambda function to encrypt the data before sending it to the S3 bucket.

Enable client encryption for the bucket
