Questions # 21:

A company deploys an application on on-premises devices in the company ' s on-premises data center. The company uses an AWS Direct Connect connection between the data center and the company ' s AWS account. During initial setup of the on-premises devices and during application updates, the application needs to retrieve configuration files from an Amazon Elastic File System (Amazon EFS) file system. All traffic from the on-premises devices to Amazon EFS must remain private and encrypted. The on-premises devices must follow the principle of least privilege for AWS access. The company ' s DevOps team needs the ability to revoke access from a single device without affecting the access of the other devices. Which combination of steps will meet these requirements? (Select TWO.)

Questions # 22:

A company is hosting a web application in an AWS Region. For disaster recovery purposes, a second region is being used as a standby. Disaster recovery requirements state that session data must be replicated between regions in near-real time and 1% of requests should route to the secondary region to continuously verify system functionality. Additionally, if there is a disruption in service in the main region, traffic should be automatically routed to the secondary region, and the secondary region must be able to scale up to handle all traffic.

How should a DevOps engineer meet these requirements?

Options:

A.

In both regions, deploy the application on AWS Elastic Beanstalk and use Amazon DynamoDB global tables for session data. Use an Amazon Route 53 weighted routing policy with health checks to distribute the traffic across the regions.


B.

In both regions, launch the application in Auto Scaling groups and use DynamoDB for session data. Use a Route 53 failover routing policy with health checks to distribute the traffic across the regions.


C.

In both regions, deploy the application in AWS Lambda, exposed by Amazon API Gateway, and use Amazon RDS for PostgreSQL with cross-region replication for session data. Deploy the web application with client-side logic to call the API Gateway directly.


D.

In both regions, launch the application in Auto Scaling groups and use DynamoDB global tables for session data. Enable an Amazon CloudFront weighted distribution across regions. Point the Amazon Route 53 DNS record at the CloudFront distribution.

Questions # 26:

A company uses an organization in AWS Organizations to manage multiple AWS accounts. The company has enabled all features for the organization. The member accounts under one OU contain S3 buckets that store sensitive data.

A DevOps engineer wants to ensure that only IAM principals from within the organization can access the S3 buckets in the OU.

Which solution will meet this requirement?

Options:

A.

Create an SCP in the management account of the organization to restrict Amazon S3 actions by using the aws:PrincipalAccount condition. Apply the SCP to the OU.


B.

Create an IAM permissions boundary in the management account of the organization to restrict access to Amazon S3 actions by using the aws:PrincipalOrgID condition.


C.

Configure AWS Resource Access Manager (AWS RAM) to restrict access to S3 buckets in the OU so the S3 buckets cannot be shared outside the organization.


D.

Create a resource control policy (RCP) in the management account of the organization to restrict Amazon S3 actions by using the aws:PrincipalOrgID condition. Apply the RCP to the OU.

Questions # 27:

A company builds a container image in an AWS CodeBuild project by running Docker commands. After the container image is built, the CodeBuild project uploads the container image to an Amazon S3 bucket. The CodeBuild project has an IAM service role that has permissions to access the S3 bucket.

A DevOps engineer needs to replace the S3 bucket with an Amazon Elastic Container Registry (Amazon ECR) repository to store the container images. The

DevOps engineer creates an ECR private image repository in the same AWS Region of the CodeBuild project. The DevOps engineer adjusts the IAM service role with the permissions that are necessary to work with the new ECR repository. The DevOps engineer also places new repository information into the docker build command and the docker push command that are used in the buildspec.yml file.

When the CodeBuild project runs a build job, the job fails when the job tries to access the ECR repository.

Which solution will resolve the issue of failed access to the ECR repository?

Options:

A.

Update the buildspec.yml file to log in to the ECR repository by using the aws ecr get-login-password AWS CLI command to obtain an authentication token. Update the docker login command to use the authentication token to access the ECR repository.


B.

Add an environment variable of type SECRETS_MANAGER to the CodeBuild project. In the environment variable, include the ARN of the CodeBuild project ' s IAM service role. Update the buildspec.yml file to use the new environment variable to log in with the docker login command to access the ECR repository.


C.

Update the ECR repository to be a public image repository. Add an ECR repository policy that allows the IAM service role to have access.


D.

Update the buildspec.yml file to use the AWS CLI to assume the IAM service role for ECR operations. Add an ECR repository policy that allows the IAM service role to have access.

Questions # 28:

A company uses Amazon Elastic Kubernetes Services (Amazon EKS) to host containerized applications that are available in Amazon Elastic Container Registry (Amazon ECR).

The company currently launches EKS clusters in the company ' s development environment by using the AWS CLI aws eks create-cluster command. The company uses the aws eks create-addon command to install required add-ons. All installed add-ons are currently version compatible with the version of Kubernetes that the company uses. All clusters exclusively use managed node groups for compute capacity.

Some of the EKS clusters require a version upgrade. A DevOps engineer must ensure that upgrades continuously occur within the AWS standard support schedule.

Which solution will meet this requirement with the LEAST operational overhead?

Options:

A.

Run the aws eks update-cluster-version command, providing appropriate arguments such as cluster name and version number.


B.

Enable EKS Auto Mode on all EKS clusters. Remove all existing managed node groups.


C.

Run the eksctl command to upgrade the EKS clusters. Provide appropriate arguments such as cluster name and version number.

Questions # 29:

A DevOps administrator is responsible for managing the security of a company ' s Amazon CloudWatch Logs log groups. The company’s security policy states that employee IDs must not be visible in logs except by authorized personnel. Employee IDs follow the pattern of Emp-XXXXXX, where each X is a digit.

An audit discovered that employee IDs are found in a single log file. The log file is available to engineers, but the engineers are not authorized to view employee IDs. Engineers currently have an AWS IAM Identity Center permission that allows logs:* on all resources in the account.

The administrator must mask the employee ID so that new log entries that contain the employee ID are not visible to unauthorized personnel.

Which solution will meet these requirements with the MOST operational efficiency?

Options:

A.

Create a new data protection policy on the log group. Add an Emp-\d{6} custom data identifier configuration. Create an IAM policy that has a Deny action for the " Action " : " logs:Unmask " permission on the resource. Attach the policy to the engineering accounts.


B.

Create a new data protection policy on the log group. Add managed data identifiers for the personal data category. Create an IAM policy that has a Deny action for the " NotAction " : " logs:Unmask " permission on the resource. Attach the policy to the engineering accounts.


C.

Create an AWS Lambda function to parse a log file entry, remove the employee ID, and write the results to a new log file. Create a Lambda subscription filter on the log group and select the Lambda function. Grant the lambda:InvokeFunction permission to the log group.


D.

Create an Amazon Data Firehose delivery stream that has an Amazon S3 bucket as the destination. Create a Firehose subscription filter on the log group that uses the Firehose delivery stream. Remove the " logs:* " permission on the engineering accounts. Create an Amazon Macie job on the S3 bucket that has an Emp-\d{6} custom identifier.
