Exam 12: AWS DevOps Engineer - Professional (DOP-C01)

A company is using Docker containers for an application deployment and wants to move its application to AWS. The company currently manages its own clusters on premises to manage the deployment of these containers. It wants to deploy its application to a managed service in AWS and wants the entire flow of the deployment process to be automated. In addition, the company has the following requirements: Focus first on the development workload. The environment must be easy to manage. Deployment should be repeatable and reusable for new environments. Store the code in a GitHub repository. Which solution will meet these requirements?

A company is implementing a well-architected design for its globally accessible API stack. The design needs to ensure both high reliability and fast response times for users located in North America and Europe. The API stack contains the following three tiers: Amazon API Gateway AWS Lambda Amazon DynamoDB Which solution will meet the requirements?

When deploying to a Docker swarm, which section of the docker-compose file defines configuration related to the deployment and running of services?

A DevOps Engineer is tasked with moving a mission-critical business application running in Go to AWS. The Development team running this application is understaffed and requires a solution that allows the team to focus on application development. They also want to enable blue/green deployments and perform A/B testing. Which solution will meet these requirements?

What is the correct syntax for the AWS command to create a single region trail?

An online company uses Amazon EC2 Auto Scaling extensively to provide an excellent customer experience while minimizing the number of running EC2 instances. The company's self-hosted Puppet environment in the application layer manages the configuration of the instances. The IT manager wants the lowest licensing costs and wants to ensure that whenever the EC2 Auto Scaling group scales down, removed EC2 instances are deregistered from the Puppet master as soon as possible. How can the requirement be met?

You are building out a layer in a software stack on AWS that needs to be able to scale out to react to increased demand as fast as possible. You are running the code on EC2 instances in an Auto Scaling Group behind an ELB. Which application code deployment method should you use?

A company has multiple development groups working in a single shared AWS account. The Senior Manager of the groups wants to be alerted via a third-party API call when the creation of resources approaches the service limits for the account. Which solution will accomplish this with the LEAST amount of development effort?

You need your API backed by DynamoDB to stay online during a total regional AWS failure. You can tolerate a couple minutes of lag or slowness during a large failure event, but the system should recover with normal operation after those few minutes. What is a good approach?

An ecommerce company is looking for ways to deploy an application on AWS that satisfies the following requirements: Has a simple and automated application deployment process. Has minimal deployment costs while ensuring that at least half of the instances are available to receive end-user requests. If the application fails, an automated healing mechanism will replace the affected instances. Which deployment strategy will meet these requirements?

A company's popular global web application is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB) using an Auto Scaling group. The company is launching a new feature and expects unpredictable spikes in web traffic. The site currently includes a large amount of media content, and the new feature adds the ability to submit ratings and comments that will be stored in a new Amazon DynamoDB table. A DevOps Engineer is tasked with ensuring the web application can scale with the increased traffic and workload Which combination of steps will accomplish this? (Choose two.)

Which of these is not a CloudFormation Helper Script?

Amazon Inspector agent collects telemetry data during assessment run and sends this data to Amazon Inspector dedicated S3 bucket for analysis. How can you access telemetry data out of Amazon Inspector and how can you benefit from this data in securing your resources?

Your DevOps team is responsible for a multi-tier, Windows-based web application consisting of web servers, Amazon RDS database instances, and a load balancer behind Amazon Route53. You have been asked by your manager to build a cost-effective rolling deployment solution for this web application. What method should you use?

You have a code repository that uses Amazon S3 as a data store. During a recent audit of your security controls, some concerns were raised about maintaining the integrity of the data in the Amazon S3 bucket. Another concern was raised around securely deploying code from Amazon S3 to applications running on Amazon EC2 in a virtual private cloud. What are some measures that you can implement to mitigate these concerns? (Choose two.)

A DevOps Engineer is developing a deployment strategy that will allow for data-driven decisions before a feature is fully approved for general availability. The current deployment process uses AWS CloudFormation and blue/green-style deployments. The development team has decided that customers should be randomly assigned to groups, rather than using a set percentage, and redirects should be avoided. What process should be followed to implement the new deployment strategy?

A DevOps Engineer is building a multi-stage pipeline with AWS CodePipeline to build, verify, stage, test, and deploy an application. There is a manual approval stage required between the test and deploy stages. The Development team uses a team chat tool with webhook support. How can the Engineer configure status updates for pipeline activity and approval requests to post to the chat tool?

If a variable is assigned in the `vars' section of a playbook, where is the proper place to override that variable?

A company wants to use AWS development tools to replace its current bash deployment scripts. The company currently deploys a LAMP application to a group of Amazon EC2 instances behind an Application Load Balancer (ALB). During the deployments, the company unit tests the committed application, stops and starts services, unregisters and re-registers instances with the load balancer, and updates file permissions. The company wants to maintain the same deployment functionality through the shift to using AWS services. Which solution will meet these requirements?

A company requires an RPO of 2 hours and an RTO of 10 minutes for its data and application at all times. An application uses a MySQL database and Amazon EC2 web servers. The development team needs a strategy for failover and disaster recovery. Which combination of deployment strategies will meet these requirements? (Choose two.)
