Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q250-Q255):

NEW QUESTION # 250
You are administering a continuous integration application that polls version control for changes and then launches new Amazon EC2 instances for a full suite of build tests. What should you do to ensure the lowest overall cost while being able to run as many tests in parallel as possible?

  • A. Perform syntax and build tests on the continuous integration system before launching the new Amazon EC2 instance unit and integration tests.
  • B. Perform syntax checking on the continuous integration system before launching a new AWS Data Pipeline for coordinating the output of unit, integration, and build tests.
  • C. Perform syntax checking on the continuous integration system before launching a new Amazon EC2 instance for build test, unit and integration tests.
  • D. Perform all tests on the continuous integration system, using AWS OpsWorks for unit, integration, and build tests.

Answer: A

Explanation:
Explanation
Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.
Option A and D are invalid because you can do build tests on a CI system and not only Syntax tests. And Syntax tests are normally done during coding time and not during the build time.
Option C is invalid because Opswork is ideally not used for build and integration tests.
For an example of a Continuous integration system, please refer to the Jenkins system via the url below

  • A. AWS EMR
  • B. AWS RedShift
  • C. AWS DynamoDB
  • D. AWS Elasticsearch Service

Answer: D

Explanation:
Amazon Elasticsearch Service (Amazon ES) is a managed service that makes it easy to deploy, operate, and scale Elasticsearch clusters in the AWS cloud.

NEW QUESTION # 252
An ecommerce company is running an application on AWS. The company wants to create a standby disaster recovery solution in an additional Region that keeps the current application code. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an EC2 Auto Scaling group across multiple Availability Zones. The database layer is hosted on an Amazon RDS MySQL Multi-AZ DB instance. Amazon Route 53 DNS records point to the ALB.
Which combination of actions will meet these requirements with the LOWEST cost? (Choose three.)

  • A. Create a cross-Region RDS read replica in the new standby Region.
  • B. Provision the ALB and Auto Scaling group in the new standby Region and set the desired capacity to 1.
  • C. Configure a failover routing policy for the application DNS entry.
  • D. Configure a geolocation routing policy for the application DNS entry.
  • E. Provision the ALB and Auto Scaling group in the new standby Region and set the desired capacity to match the active Region.
  • F. Migrate the database layer to Amazon DynamoDB and enable global replication to the new standby Region.

Answer: B,C,E


NEW QUESTION # 253
When specifying more than one conditional requirements for a task, what is the proper method?

  • A. - when: foo == "hello" && bar == "world"
  • B. - when: foo == "hello" and bar == "world"
  • C. - when: foo == "hello" - when: bar == "world"
  • D. - when: foo is "hello" and bar is "world"

Answer: B

Explanation:
Ansible will allow you to stack conditionals using `and' and `or'. It requires it to be in the same
`when' statement, comparisons must be `==' for equals or `!=' for not equals and the `and/or' must be written as such, not `&&/||'.
Reference: http://docs.ansible.com/ansible/playbooks_conditionals.html#the-when-statement


NEW QUESTION # 254
You are using Elastic Beanstalk to manage your application. You have a SQL script that needs to only be executed once per deployment no matter how many EC2 instances you have running. How can you do this?

  • A. Use a "Container command" within an Elastic Beanstalk configuration file to execute the script, ensuring that the "leader only" flag is set to false.
  • B. Use Elastic Beanstalk version and a configuration file to execute the script, ensuring that the "leader only" flag is set to true.
  • C. Use a "Container command" within an Elastic Beanstalk configuration file to execute the script, ensuring that the "leader only" flag is set to true.
  • D. Use a "leader command" within an Elastic Beanstalk configuration file to execute the script, ensuring that the "container only" flag is set to true.

Answer: C

Explanation:
Explanation
You can use the container_commands key to execute commands that affect your application source code.
Container commands run after the application and web server have been set up and the application version archive has been extracted, but before the application version is deployed. Non-container commands and other customization operations are performed prior to the application source code being extracted.
You can use leader_only to only run the command on a single instance, or configure a test to only run the command when a test command evaluates to true. Leader-only container commands are only executed during environment creation and deployments, while other commands and server customization operations are performed every time an instance is provisioned or updated. Leader-only container commands are not executed due to launch configuration changes, such as a change in the AMI Id or instance type.
