DRAG DROP (DRAG AND DROP IS NOT SUPPORTED)



Drag and drop the scenarios from the left onto the cloud strategy categories on the right.

  1. See Explanation section for answer.

Answer(s): A

Explanation:



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?

  1. network
  2. CPU/GPU
  3. disk I/O
  4. memory

Answer(s): B



An application has been designed based on microservices. The application is deployed on Kubernetes using multiple pods that share the same IP address. Each pod is responsible for a service in the application.
Which command validates the success of the application deployment?

  1. kubectl get pods -o wide -w
  2. kubectl rollout status deployment
  3. kubectl describe pods/
  4. kubectl rollout history deployment

Answer(s): B



Refer to the exhibit.



An organization has issues with code-based failures after implementing a CI/CD pipeline to automate the builds and deployment phases of an application.
Which action must be added to the pipeline, after the application is deployed in the staging environment to minimize failures and to ensure a successful continuous deployment?

  1. Restructuring and monitoring tests must be run after it is promoted to production
  2. Restructuring and monitoring tests must be run before it is promoted to production
  3. Functional and nonfunctional tests must be run after it is promoted to production
  4. Functional and nonfunctional tests must be run before it is promoted to production

Answer(s): D

Explanation:

According to Cisco's Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, it is important to run functional and non-functional tests before promoting the application to production. This is essential in order to identify and address any issues that could cause code-based failures. Additionally, a pipeline should include automated tests that can be used to verify that processes are running correctly. By running these tests before promoting to production, you can ensure that any potential issues are identified and addressed before the application is released.



DRAG DROP (DRAG AND DROP IS NOT SUPPORTED)
A DevOps engineer is designing a precheck validation of the network state in a CI/CD pipeline and must implement this workflow:
· Take a source Docker image named alpine
· Define two stages named build and push
· Check network connectivity before the stages run
· Fetch the latest Docker image
· Create a new Docker image and push it to the registry
· Tag the new Docker image as the latest version

Drag and drop the code snippets from the bottom onto the boxes in the GitLab CI configuration to achieve the requirements for the design. Not all options are used.
