B. Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.

C. Use only software modules that are written by the internal team.

D. 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.

E. Ensure that the code repository server has enabled drive encryption and stores the keys on a Trusted Platform Module or Hardware Security Module.

Question 2:

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?

A. terraform plan

B. terraform check

C. terraform fmt

D. terraform validate

Question 3:

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?

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.

Question 4:

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?

A. recreate

B. blue/green

C. rolling

D. canary

Question 5:

Which description of a canary deployment is true?

A. deployment by accident

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

C. deployment relating to data mining development

D. deployment to a limited set of servers or users

Question 6:

Refer to the exhibit. What is causing the request code to fail?

A. Rython3 is not compatible with requests.

B. The requests library is not imported.

C. The requests library is not installed.

D. The requests coming into stdin fail because device_ip cannot be parsed.

Question 7:

B. pyATS

C. Genie CLI

D. Travis CI

Question 8:

Which two actions help limit the attack surface of your Docker container? (Choose two.)

A. Run only a single service in each container.

B. Run all services in a single image.

C. Use version tags for base images and dependencies.

D. Use Kali Linux as a base image.

E. Download images over HTTPS supporting sites.

Question 9:

A DevOps engineer has built a container to host a web server and it must run as an executable. Which command must be configured in a Dockerfile to accomplish this goal?

A. ENTRYPOINT

B. ENTRYPOINT [“/usr/sbin/apache2ctl”, “-D”, “FOREGROUND”]

C. ENTRYPOINT [“BACKGROUND”, “-D”, “/usr/sbin/apache2ctl”]

D. ENTRYPOINT {usr/sbin/apache2ctl}

Question 10:

A Microservices architecture pattern has been applied and the system has been architected as a set of services. Each service is deployed as a set of instances for throughput and availability.

In which two ways are these services packaged and deployed? (Choose two.)

A. Service instances must be isolated from one another.

B. Service must be independently deployable and scalable.

C. Service is written using the same languages, frameworks, and framework versions.

D. Service must be dependent, deployable, and scalable.

E. Service instances do not need to be isolated from one another.

Question 11:

Refer to the exhibit. What is the reason for this error message?

B. The requests module is not installed.

C. The required dependencies for the requests module are not installed.

D. The site-packages directory has been corrupted.

C. testing only the amd64 architecture

D. testing PostgreSQL deployment in an Alpine Linux VM

Question 15:

An interface on a router as a Layer 3 link has been configured to another device by updating an Ansible playbook that is executed via a CI/CD pipeline. The Ansible playbook was written to push the configuration change using the ios_config module.

Which automated test validates that the interface is functioning as it should?

A. Add a pipeline step that runs the playbook a second type. If it does not modify the device on the second run, then the interface is correctly configured.

B. Automated testing is already built in because the playbook execution is successful only after Ansible validates that it applied the change.

C. Add a pipeline step that captures and parses the packet flow for the interface.

D. Add a pipeline step that captures and parses the show IP interface output so that the operational state can be referenced.
