Why did the pipeline fail to start?

A. The CI server was not configured as a Git remote for the repository.

B. The webhook call from the code repository did not reach the CI server.

C. Configuration changes must be sent to the pipeline, which then updates the repository.

D. The pipeline must be started manually after the code repository is updated.

B. deployment that is rolled back automatically after a configurable amount of minutes

C. deployment relating to data mining development

A developer is creating a script to test APIs. The Cisco Webex API and a CI/CD pipeline are tested to ensure that the script runs without problems. The script is executed without issues locally, but the CI/CD system returns the error shown. What is the problem with the script?

A. The CI/CD system is configured incorrectly to import the dependencies to the code

B. The code is pushed incorrectly to the CI/CD system

C. The version of Python is wrong in the CI/CD pipeline

D. The CI/CD system is configured incorrectly to download the required dependencies

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?

A. kubectl get pods -o wide -w

B. kubectl rollout status deployment

C. kubectl describe pods/

D. kubectl rollout history deployment

What is a benefit of monitoring the CI/CD pipeline?

A. troubleshoots distributed systems performance

B. proactively deploys new servers if needed

C. analyzes network outages that affect the network and server infrastructure

D. provides insight into how efficiently the development team is operating

A team must roll out updates on the production instance of an application. To avoid any service down time, the new version must be released alongside the old version. After the team ensures that the new version operates as it should, traffic will be redirected to the new version. Then the old version will be shut down.

Which deployment strategy must be used?

A. rolling

B. blue/green

C. shadow

D. canary

An IT team plans to deploy a new service built on top of an existing service. The capacity needed for the new service is difficult to estimate because the demand for the new service is undetermined. The team has these deployment requirements:

1.

A subset of the users of the original service must be migrated to the new service based on their profile

2.

The new service must be rolled back easily if capacity exceeds estimates

Which deployment strategy must be used?

A. rolling

B. blue/green

C. geolocation

D. canary
