Question 1

An AWS CodePipeline pipeline has implemented a code release process. The pipeline is integrated with AWS CodeDeploy to deploy versions of an application to multiple Amazon EC2 instances for each CodePipeline stage.

During a recent deployment, the pipeline failed due to a CodeDeploy issue. The DevOps team wants to improve monitoring and notifications during deployment to decrease resolution times.

What should the DevOps engineer do to create notifications when issues are discovered?

A : Implement Amazon CloudWatch Logs for CodePipeline and CodeDeploy, create an AWS Config rule to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

B : Implement Amazon EventBridge for CodePipeline and CodeDeploy, create an AWS Lambda function to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

C : Implement AWS CloudTrail to record CodePipeline and CodeDeploy API call information, create an AWS Lambda function to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

D : Implement Amazon EventBridge for CodePipeline and CodeDeploy, create an Amazon Inspector assessment target to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

Answer: B

Question 2

A company has an on-premises application that is written in Go. A DevOps engineer must move the application to AWS. The company's development team wants to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?

A : Deploy the application on an Amazon EC2 instance, and create an AMI of the instance. Use the AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use Elastic Load Balancing to distribute traffic. When changes are made to the application, a new AMI will be created, which will initiate an EC2 instance refresh.

B : Use Amazon Lightsail to deploy the application. Store the application in a zipped format in an Amazon S3 bucket. Use this zipped version to deploy new versions of the application to Lightsail. Use Lightsail deployment options to manage the deployment.

C : Use AWS CodeArtifact to store the application code. Use AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use Elastic Load Balancing to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodeArtifact and create a new CodeDeploy deployment.

D : Use AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3. Use that location to deploy new versions of the application. Use Elastic Beanstalk to manage the deployment options

Answer: D

Question 3

A company's security policies require the use of security hardened AMIS in production environments. A DevOps engineer has used EC2 Image Builder to create a pipeline that builds the AMIs on a recurring schedule. The DevOps engineer needs to update the launch templates of the companys Auto Scaling groups. The Auto Scaling groups must use the newest AMIS during the launch of Amazon EC2 instances. Which solution will meet these requirements with the MOST operational efficiency?

A :

Configure an Amazon EventBridge rule to receive new AMI events from Image Builder. Target an AWS Systems Manager Run Command document that updates the launch templates of the Auto Scaling groups with the newest AMI ID.

B :

Configure an Amazon EventBridge rule to receive new AMI events from Image Builder. Target an AWS Lambda function that updates the launch templates of the Auto Scaling groups with the newest AMI ID.

C :

Configure the launch template to use a value from AWS Systems Manager Parameter Store for the AMI ID. Configure the Image Builder pipeline to update the Parameter Store value with the newest AMI ID.

D :

Configure the Image Builder distribution settings to update the launch templates with the newest AMI ID. Configure the Auto Scaling groups to use the newest version of the launch template.

Answer: C

Question 4

A leading software development company has various web applications hosted in an Auto Scaling group of EC2 instances which are designed for high availability and fault tolerance. They are using AWS CloudFormation to easily manage their cloud infrastructure as code as well as for deployment. Currently, they have to manually update their CloudFormation templates for every new available AMI of their application. This procedure is prone to human errors and entails a high management overhead on their deployment process.

Which of the following is the MOST suitable and cost-effective solution that the DevOps engineer should implement to automate this process?

A : Pull the new AMI IDs using an AWS Lambda-backed custom resource in the CloudFormation template. Reference the AMI ID that the custom resource fetched in the launch configuration resource block.

B : Configure the CloudFormation template to use AMI mappings. Integrate AWS Lambda and Amazon CloudWatch Events to create a function that regularly runs every hour to detect new AMIs as well as update the mapping in the template. Reference the AMI mappings in the launch configuration resource block.

C : Configure the AWS CloudFormation template to use conditional statements to check if new AMIs are available. Fetch the new AMI ID using the cfn-init helper script and reference it in the launch configuration resource block.

D : Launch an EC2 instance to run a custom shell script every hour to check for new AMIs. The script should update the launch configuration resource block of the CloudFormation template with the new AMI ID if there are new ones available.

Answer: A

Question 5

A leading telecommunications company is using CloudFormation templates to deploy enterprise applications to their production, staging, and development environments in AWS. Their current process involves manual changes to their CloudFormation templates in order to specify the configuration variables and static attributes for each environment. The DevOps Engineer was tasked to set up automated deployments using AWS CodePipeline and ensure that the CloudFormation template is reusable across multiple pipelines.

How should the DevOps Engineer satisfy this requirement?

A : Set up a Lambda-backed custom resource in the CloudFormation templates. Configure the custom resource to monitor the status of the pipeline in AWS CodePipeline in order to detect which environment was launched. Use the cfn-init helper script to modify the launch configuration of each application stack based on its environment.

B : Launch a new pipeline using AWS CodePipeline that has multiple stages for each environment and configure it to use input parameters. Switch the associated UserData of the EC2 instances to match the environment where the application stack is being launched using CloudFormation mappings. Specify parameter overrides for AWS CloudFormation actions.

C : Manually configure the CloudFormation templates to use input parameters. Add a configuration that whenever the CloudFormation stack is updated, it will dynamically modify the LaunchConfiguration and UserData sections of the EC2 instances.

D : Launch a new pipeline using AWS CodePipeline for each environment with multiple stages for each application. Trigger the CloudFormation deployments using a Lambda function to dynamically modify the UserData of the EC2 instances that were launched in each environment.
