Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q398-Q403):

NEW QUESTION # 398
You have a development team that is continuously spending a lot of time rolling back updates for an
application. They work on changes, and if the change fails, they spend more than 5-6h in rolling back the
update. Which of the below options can help reduce the time for rolling back application versions.

  • A. Use Elastic Beanstalk and re-deploy using Application Versions
  • B. Use OpsWorks and re-deploy using rollback feature.
  • C. Use CloudFormation and update the stack with the previous template
  • D. Use S3 to store each version and then re-deploy with Elastic Beanstalk

Answer: A

Explanation:
Explanation
Option B is invalid because Clastic Beanstalk already has the facility to manage various versions and you don't
need to use S3 separately for this.
Option C is invalid because in Cloudformation you will need to maintain the versions. Clastic Beanstalk can
so that automatically for you.
Option D is good for production scenarios and Clastic Beanstalk is great for development scenarios.
AWS beanstalk is the perfect solution for developers to maintain application versions.
With AWS Clastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without
worrying about the infrastructure that runs those
applications. AWS Clastic Beanstalk reduces management complexity without restricting choice or control.
You simply upload your application, and AWS Clastic
Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application
health monitoring.

NEW QUESTION # 399
You need to deploy an AWS stack in a repeatable manner across multiple environments. You have selected CloudFormation as the right tool to accomplish this, but have found that there is a resource type you need to create and model, but is unsupported by CloudFormation. How should you overcome this challenge?

  • A. Submit a ticket to the AWS Forums. AWS extends CloudFormation Resource Types by releasing tooling to the AWS Labs organization on GitHub. Their response time is usually 1 day, and they complete requests within a week or two.
  • B. Use a CloudFormation Custom Resource Template by selecting an API call to proxy for create, update, and delete actions. CloudFormation will use the AWS SDK, CLI, or API method of your choosing as the state transition function for the resource type you are modeling.
  • C. Create a CloudFormation Custom Resource Type by implementing create, update, and delete functionality, either by subscribing a Custom Resource Provider to an SNS topic, or by implementing the logic in AWS Lambda.
  • D. Instead of depending on CloudFormation, use Chef, Puppet, or Ansible to author Heat templates, which are declarative stack resource definitions that operate over the OpenStack hypervisor and cloud environment.

Answer: C

Explanation:
Custom resources provide a way for you to write custom provisioning logic in AWS CloudFormation template and have AWS CloudFormation run it during a stack operation, such as when you create, update or delete a stack. For more information, see Custom Resources.

NEW QUESTION # 400
A company is testing a web application that runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones. The company uses a blue/green deployment process with immutable instances when deploying new software. During testing, users are being automatically logged out of the application at random times. Testers also report that, when a new version of the application is deployed, all users are logged out. The Development team needs a solution to ensure users remain logged in across scaling events and application deployments.
What is the MOST efficient way to ensure users remain logged in?

  • A. Enable session sharing on the load balancer and modify the application to read from the session store.
  • B. Enable smart sessions on the load balancer and modify the application to check for an existing session.
  • C. Modify the application to store user session information in an Amazon ElastiCache cluser.
  • D. Store user session information in an Amazon S3 bucket and modify the application to read session information from the bucket.

Answer: C


NEW QUESTION # 401
You are the IT administrator for your company. You have the responsibility of creating development environments which would confirm to the LAMP development stack. The requirement is that the development team always gets the latest version of the LAMP stack each time a new instance is launched. Which of the following is an efficient and effective way to implement this requirement? Choose 2 answers from the options given below

  • A. Create a cloudformation template and use the cloud-init directives to download and the install the LAMP stack packages.
  • B. Use the User data section and use a custom script which will be used to download the necessary LAMP stack packages.
  • C. Create an AMI with all the artifacts of the LAMP stack and provide an instance to the development team based on the AMI.
  • D. Create an EBS Volume with the LAMP stack and attach it to an instance whenever it is required.

Answer: A,B

Explanation:
Explanation
Using User data and cloud-init directives you can always ensure you download the latest version of the LAMP stack and give it to the development teams. With AMI's you will always have the same version and will need to create an AMI everytime the version of the LAMP stack changes.
The AWS Documentation mentions
When you launch an instance in Amazon CC2, you have the option of passing user data to the instance that can be used to perform common automated configuration tasks and even run scripts after the instance starts. You can pass two types of user data to Amazon CC2: shell scripts and cloud-init directives. You can also pass this data into the launch wizard as plain text, as a file (this is useful for launching instances using the command line tools), or as base64-encoded text (for API calls).
For more information on User data please refer to the below link:
* http://docs.aws.amazon.com/AWSCC2/latest/UserGuide/user-data.html


NEW QUESTION # 402
By default in Opswork, how many application versions can you rollback up to?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: D

Explanation:
Explanation
The AWS Documentation mentions the following Restores the previously deployed app version. For example, if you have deployed the app three times and then run Rollback, the server will serve the app from the second deployment. If you run Rollback again, the server will serve the app from the first deployment. By default, AWS OpsWorks Stacks stores the five most recent deployments, which allows you to roll back up to four versions. If you exceed the number of stored versions, the command fails and leaves the oldest version in place.
