• Question 78:

  A developer is creating an application based on microservices. The application will be used as a central repository for all company's documents. One of the microservices in the application will perform image processing. This microservice must autoscale to meet the current load and avoid down time.

  Which metric must be used to trigger autoscaling events?

  A. network
  B. CPU/GPU

• Question 79:

  A company has a CI/CD pipeline implemented to automate application deployment. An urgent change is required in the production environment. A developer produces and tests the required change in the company's environment, but the pipeline fails when pushed.

  Which action conforms to the rules of a CI/CD pipeline and enables the pipeline to pass?

  A. Remove the failing test.
  B. Manually deploy the change into the production environment
  C. Use a backup pipeline
  D. Replicate the production environment in the pipeline before applying
  D. Replicate the production environment in the pipeline before applying

  ---

  This ensures that the change is applied in the same environment that it was tested in, and that the pipeline will pass. This is in accordance with the rule of a CI/CD pipeline that states that the same environment should be used for testing and deploying code into production. As stated in the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, "the same environment should be used for testing and deploying code into production, or the pipeline will fail."

• Question 80:

  DRAG DROP
