AWS-DevOps-Engineer-Professional Exam Question 216

A Developer is designing a continuous deployment workflow for a new Development team to facilitate the process for source code promotion in AWS. Developers would like to store and promote code for deployment from development to production while maintaining the ability to roll back that deployment if it fails.
Which design will incur the LEAST amount of downtime?

A.Create one repository in AWS CodeCommit. Create a development branch to hold merged changes.
Use AWS CodeBuild to build and test the code stored in the development branch triggered on a new commit. Merge to the master and deploy to production by using AWS CodeDeploy for a blue/green deployment.

B.Create a shared Amazon S3 bucket for the Development team to store their code. Set up an Amazon CloudWatch Events rule to trigger an AWS Lambda function that deploys the code to production by using AWS CodeDeploy for a blue/green deployment.

C.Create one repository for development code in AWS CodeCommit and another repository to hold the production code. Use AWS CodeBuild to merge development and production repositories, and deploy to production by using AWS CodeDeploy for a blue/green deployment.

D.Create one repository for each Developer in AWS CodeCommit and another repository to hold the production code. Use AWS CodeBuild to merge development and production repositories, and deploy to production by using AWS CodeDeploy for a blue/green deployment.

AWS-DevOps-Engineer-Professional Exam Question 217

According to Information Security Policy, changes to the contents of objects inside production Amazon S3 bucket that contain encrypted secrets should only be made by a trusted group of administrators. How should a DevOps Engineer create real-time, automated checks to meet this requirement?

A.Create a metrics filter for Amazon CloudWatch logs to check for Amazon S3 bucket-level permission changes and to check the IAM user's membership in an administrator's IAM role.

B.Create a periodic AWS Config rule to query AWS CloudTrail logs for changes to the Amazon S3 bucket-level permissions and to check the IAM user's membership in an administrator's IAM role.

C.Create an AWS Lambda function that is triggered by Amazon S3 data events for object changes and that also checks the IAM user's membership in an administrator's IAM role.

D.Create a periodic AWS Config rule to query Amazon S3 Logs for changes and to check the IAM user's membership in an administrator's IAM role.

AWS-DevOps-Engineer-Professional Exam Question 218

You need to implement Blue/Green Deployment for several multi-tier web applications. Each of them has Its Individual infrastructure:
Amazon Elastic Compute Cloud (EC2) front-end servers, Amazon ElastiCache clusters, Amazon Simple Queue Service (SQS) queues, and Amazon Relational Database (RDS) Instances.
Which combination of services would give you the ability to control traffic between different deployed versions of your application?

A.Create one AWS Elastic Beanstalk application and all AWS resources (using configuration files inside the application source bundle) for each web application. New versions would be deployed using Elastic Beanstalk environments and using the Swap URLs feature.

B.Using AWS CloudFormation templates, create one Elastic Beanstalk application and all AWS resources (in the same template) for each web application. New versions would be deployed using AWS CloudFormation templates to create new Elastic Beanstalk environments, and traffic would be balanced between them using weighted Round Robin (WRR) records in Amazon Route 53. >/

C.Using AWS CloudFormation templates, create one Elastic Beanstalk application and all AWS resources (in the same template) for each web application. New versions would be deployed updating a parameter on the CloudFormation template and passing it to the cfn-hup helper daemon, and traffic would be balanced between them using Weighted Round Robin (WRR) records in Amazon Route 53.

D.Create one Elastic Beanstalk application and all AWS resources (using configuration files inside the application source bundle) for each web application. New versions would be deployed updating the Elastic Beanstalk application version for the current Elastic Beanstalk environment.

AWS-DevOps-Engineer-Professional Exam Question 219

You are hired as the new head of operations for a SaaS company. Your CTO has asked you to make debugging any part of your entire operation simpler and as fast as possible. She complains that she has no idea what is going on in the complex, service-oriented architecture, because the developers just log to disk, and it's very hard to find errors in logs on so many services. How can you best meet this requirement and satisfy your CTO?

A.Copy all log files into AWS S3 using a cron job on each instance. Use an S3 Notification Configuration on the PutBucket event and publish events to AWS Lambda. Use the Lambda to analyze logs as soon as they come in and flag issues.

B.Begin using CloudWatch Logs on every service. Stream all Log Groups into S3 objects. Use AWS EMR clusterjobs to perform adhoc MapReduce analysis and write new queries when needed.

C.Copy all log files into AWS S3 using a cron job on each instance. Use an S3 Notification Configuration on the PutBucket event and publish events to AWS Kinesis. Use Apache Spark on AWS EMR to perform at-scale stream processing queries on the log chunks and flag issues.

D.Begin using CloudWatch Logs on every service. Stream all Log Groups into an AWS Elastic search Service Domain running Kibana 4 and perform log analysis on a search cluster.

AWS-DevOps-Engineer-Professional Exam Question 220

A DevOps Engineer is leading the implementation for automating patching of Windows-based workstations in a hybrid cloud environment by using AWS Systems Manager (SSM). What steps should the Engineer follow to set up Systems Manager to automate patching in this environment?
(Select TWO.)

A.Run AWS Config to create a list of instances that are unpatched and not compliant. Create an instance scheduler job, and through an AWS Lambda function, perform the instance patching to bring them up to compliance.

B.Create an IAM service role for Systems Manager so that the ssm amazonaws.com service can execute the AssumeRole operation. Register the role to enable the creation of a service token.
Perform managed-instance activation with the newly created service role.

C.Create multiple IAM service roles for Systems Manager so that the ssm amazonaws.com service can execute the AssumeRole operation on every instance. Register the role on a per-resource level to enable the creation of a service token. Perform managed-instance activation with the newly created service role attached to each managed instance.

D.Using previously obtained activation codes and activation IDs, download and install the SSM Agent on the hybrid servers, and register the servers or virtual machines on the Systems Manager service.
Hybrid instances will show with an "i-" prefix in the SSM console as if they were provisioned as a regular Amazon EC2 instance.

E.Using previously obtained activation codes and activation IDs, download and install the SSM Agent on the hybrid servers, and register the servers or virtual machines on the Systems Manager service.
Hybrid instances will show with an "mi-" prefix in the SSM console.
