You have decided that you need to change the instance type of your production instances which are running as part of an AutoScaling group. The entire architecture is deployed using CloudFormation Template. You currently have 4 instances in Production. You cannot have any interruption in service and need to ensure 2 instances are always runningduring the update. Which of the options below listed can be used for this?

AutoScalingRollingUpdate
AutoScalingRollingUpdate
AutoScalingScheduledAction
AutoScalingScheduledAction
AutoScalingReplacingUpdate
AutoScalingReplacingUpdate
AutoScalinglntegrationUpdate
AutoScalinglntegrationUpdate
Suggested answer: A

Explanation:

The AWS::AutoScaling::AutoScalingGroup resource supports an UpdatePoIicy attribute. This is used to define how an Auto Scalinggroup resource is updated when an update to the Cloud Formation stack occurs. A common approach to updating an Auto Scaling group is to perform a rolling update, which is done by specifying the AutoScalingRollingUpdate policy. This retains the same Auto Scaling group and replaces old instances with new ones, according to the parameters specified. For more information on Autoscaling updates, please refer to the below link.

A company has multiple environments that run applications on Amazon EC2 instances. The company wants to track costs and has defined a new rule that states that all production EC2 instances must be tagged with a CostCenter tag. A DevOps engineer has created a tag policy to validate the use of the CostCenter tag, has activated the option to prevent noncompliant tagging operations for this tag, and has attached the policy to the production OU in AWS Organizations. The DevOps engineer generates a compliance report for the entire organization and ensures that all the deployed instances have the correct tags configured. The DevOps engineer also verifies that the CostCenter tag cannot be removed from an EC2 instance that runs in one of the production accounts.

After some time, the DevOps engineer notices that several EC2 instances have been launched in the production accounts without the configuration of the CostCenter tag. What should the DevOps engineer do to ensure that all production EC2 instances are launched with the CostCenter tag configured?

Attach the tag policy to the organization root to ensure that the policy applies to all EC2 instances.

Activate the AWS Config required-tags managed rule in all production accounts. Ensure that the rule evaluates the CostCenter tag.
Suggested answer: C

Explanation:

After you activate cost allocation tags, AWS uses the cost allocation tags to organize your resource costs on your cost allocation report, to make it easier for you to categorize and track your AWS costs.

Ansible provides some methods for controlling how or when a task is ran. Which of the following is a valid method for controlling a task with a loop?

- with:
- with:
- with_items:
- with_items:
- only_when:
- only_when:
- items:
- items:
Suggested answer: B

Explanation:

Ansible provides two methods for controlling tasks, loops and conditionals. The "with_items" context will allow the task to loop through a list of items, while the `when' context will allow a conditional requirement to be met for the task to run. Both can be used at the same time.

mvn javac mvn -install processor
mvn javac mvn -install processor
jar install processor
jar install processor
build jar -Dgpg.processor
build jar -Dgpg.processor
mvn clean install -Dgpg.skip=true
mvn clean install -Dgpg.skip=true
Suggested answer: D

Explanation:

The CloudTrail Processing Library is a Java library that provides an easy way to process AWS CloudTrail logs in a faulttolerant, scalable and flexible way.

A company has a single Developer writing code for an automated deployment pipeline. The Developer is storing source code in an Amazon S3 bucket for each project. The company wants to add more Developers to the team but is concerned about code conflicts and lost work. The company also wants to build a test environment to deploy newer versions of code for testing and allow Developers to automatically deploy to both environments when code is changed in the repository.

What is the MOST efficient way to meet these requirements?

Create an AWS CodeCommit repository for each project, use the master branch for production code, and create a testing branch for code deployed to testing. Use feature branches to develop new features and pull requests to merge code to testing and master branches.

A company has a web application that uses AWS Elastic Beanstalk, Amazon S3, and Amazon DynamoDB to develop a web application. The web application has increased dramatically in popularity, resulting in unpredictable spikes in traffic. A DevOps Engineer has noted that 90% of the requests are duplicate read requests to the DynamoDB table and the images stored in an S3 bucket. How can the Engineer improve the performance of the website?

A company hosts parts of a Python-based application using AWS Elastic Beanstalk. An Elastic Beanstalk CLI is being used to create and update the environments. The Operations team detected an increase in requests in one of the Elastic Beanstalk environments that caused downtime overnight. The team noted that the policy used for AWS Auto Scaling is NetworkOut. Based on load testing metrics, the team determined that the application needs to scale CPU utilization to improve the resilience of the environments. The team wants to implement this across all environments automatically. Following AWS recommendations, how should this automation be implemented?
An application running on a set of Amazon EC2 instances in an Auto Scaling group requires a configuration file to operate. The instances are created and maintained with AWS CloudFormation. A DevOps engineer wants the instances to have the latest configuration file when launched, and wants changes to the configuration file to be reflected on all the instances with a minimal delay when the CloudFormation template is updated. Company policy requires that application configuration files be maintained along with AWS infrastructure configuration files in source control. Which solution will accomplish this?
A company has built a web service that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The company has deployed the application in us-east-1. Amazon Route 53 provides an external DNS that routes traffic from example.com to the application, created with appropriate health checks. The company has deployed a second environment for the application in eu-west-1. The company wants traffic to be routed to whichever environment results in the best response time for each user. If there is an outage in one Region, traffic should be directed to the other environment. Which configuration will achieve these requirements?

A retail company wants to use AWS Elastic Beanstalk to host its online sales website running on Java. Since this will be the production website, the CTO has the following requirements for the deployment strategy: Zero downtime. While the deployment is ongoing, the current Amazon EC2 instances in service should remain in service. No deployment or any other action should be performed on the EC2 instances because they serve production traffic. A new fleet of instances should be provisioned for deploying the new application version. Once the new application version is deployed successfully in the new fleet of instances, the new instances should be placed in service and the old ones should be removed. The rollback should be as easy as possible. If the new fleet of instances fail to deploy the new application version, they should be terminated and the current instances should continue serving traffic as normal. The resources within the environment (EC2 Auto Scaling group, Elastic Load Balancing, Elastic Beanstalk DNS CNAME) should remain the same and no DNS change should be made. Which deployment strategy will meet the requirements?
