Question 212

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?
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.

Question 213

A company is building a solution for storing files containing Personally Identifiable Information (PII) on AWS. Requirements state:
All data must be encrypted at rest and in transit.
All data must be replicated in at least two locations that are at least 500 miles apart.
Which solution meets these requirements?
Question 214

A DevOps Engineer must track the health of a stateless RESTful service sitting behind a Classic ILoad Balancer. The deployment of new application revisions is through a CI/CD pipeline. If the service's latency increases beyond a defined threshold, deployment should be stopped until the service has recovered.
Which of the following methods allow for the QUICKEST detection time?
Question 215

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?
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.

Question 216

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?
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.

Question 217

You want to set up the CloudTrail Processing Library to log your bucket operations. Which command will build a .jar file from the CloudTrail Processing Library source code?
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. To set up the CloudTrail Processing Library, you first need to download CloudTrail Processing Library source from GitHub. You can then create the .jar file using this command.

Question 218

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?
Question 219

Your application requires a fault-tolerant, low-latency and repeatable method to load configurations files via Auto Scaling when Amazon Elastic Compute Cloud (EC2) instances launch. Which approach should you use to satisfy these requirements?
Question 220

Which of these is not a CloudFormation Helper Script?
Explanation:
This is the complete list of CloudFormation Helper Scripts: cfn-init, cfn-signal, cfn-get-metadata, cfn-hup Reference: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-helper-scriptsreference.html
