Drag and drop the code from the bottom onto the correct location in the exhibit to complete the tasks section of the Ansible playbook so that it accomplishes your goal.

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?

Which action must be used to prevent developers from accidentally committing secrets in the code?

Refer to the exhibit.

A distributed application contains data services that connect to databases via JDBC and to other remote services via HTTP. The overall response time is too long, and AppDynamics is used to investigate the root cause. From the application flow map, a specific data service running on Docker has been identified whose response time is over 10 seconds.

Which action resolves the issue?

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
