Demo Questions

Question 1
A DevOps engineer must validate the working state of the network before implementing a CI/CD pipeline model. Which configuration management tool is designed to accomplish this?
  1. Jenkins
  2. Genie CLI
  3. Travis CI
  4. Python YAML data libraries
Correct answer: A
Question 2
Which two practices help make the security of an application a more integral part of the software development lifecycle? (Choose two.)
  1. Add a step to the CI/CD pipeline that runs a dynamic code analysis tool during the pipeline execution.
  2. Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.
  3. Use only software modules that are written by the internal team.
  4. Add a step to the CI/CD pipeline to modify the release plan so that updated versions of the software are made available more often.
  5. Ensure that the code repository server has enabled drive encryption and stores the keys on a Trusted Platform Module or Hardware Security Module.
Correct answer: AE
Question 3
A CI/CD pipeline that builds infrastructure components using Terraform must be designed. A step in the pipeline is needed that checks for errors in any of the .tf files in the working directory. It also checks the existing state of the defined infrastructure.
Which command does the pipeline run to accomplish this goal?
  1. terraform plan
  2. terraform check
  3. terraform fmt
  4. terraform validate
Correct answer: D
Question 4
Which type of testing should be integrated into a CI/CD pipeline to ensure the correct behavior of all of the modules in the source code that were developed using TDD?
  1. soak testing
  2. unit testing
  3. load testing
  4. volume testing
Correct answer: B
Question 5
Refer to the exhibit. How should the Jenkins job be troubleshooted based on the error provided?
  1. Verify what the responding file created.
  2. Update pip.
  3. Install dependencies.
  4. Place the code in a container and run the job again.
Correct answer: A
Question 6
Configuration changes to the production network devices are performed by a CI/CD pipeline. The code repository and the CI tool are running on separate servers. Some configuration changes are pushed to the code repository, but the pipeline did not start.
Why did the pipeline fail to start?
  1. The CI server was not configured as a Git remote for the repository.
  2. The webhook call from the code repository did not reach the CI server.
  3. Configuration changes must be sent to the pipeline, which then updates the repository.
  4. The pipeline must be started manually after the code repository is updated.
Correct answer: C
Question 7
A new version of an application is being released by creating a separate instance of the application that is running the new code. Only a small portion of the user base will be directed to the new instance until that version has been proven stable. Which deployment strategy is this example of?
  1. recreate 
  2. blue/green
  3. rolling
  4. canary
Correct answer: D
Question 8
Which description of a canary deployment is true?
  1. deployment by accident
  2. deployment that is rolled back automatically after a configurable amount of minutes
  3. deployment relating to data mining development
  4. deployment to a limited set of servers or users
Correct answer: D
Question 9
Refer to the exhibit. What is causing the requests code to fail?
  1. Rython3 is not compatible with requests.
  2. The requests library is not imported.
  3. The requests library is not installed.
  4. The requests coming into stdin fail because device_ip cannot be parsed.
Correct answer: B
Question 10
A DevOps engineering wants to build an application implementation based on the CI/CD pipeline model. Which service should be used to provide hosted continuous service for open and private projects?
  1. Ansible
  2. pyATS
  3. Genie CLI
  4. Travis CI
Correct answer: D
