Hybrid Cloud Conference – Backend Services for Containers Cognitive Class final Exam Answers:-

Question 1. Who is the primary audience for the Make Your Solution into a Backend Service on OpenShift® track?

• Cloud-native application developers
• Cloud-native application deployers
• OpenShift® cluster administrators
• Independent Software Vendors (ISVs)
• Global Systems Integrators (GSIs)

Question 2. Which of these is not a goal of the Make Your Solution into a Backend Service on OpenShift® track?

• Make the service deploy  successfully in OpenShift
• Make the service self-managing so that customers don’t have to manage it
• Incorporate metering and billing into the service
• Get the service certified by Red Hat
• Make the service ready to add to service catalogs like Red Hat Marketplace

Question 3. covered in the Make Your Solution into a Backend Service on OpenShift® track?

• Introduction to the sessions in the track
• How to control which applications can be deployed to a cluster
• How to control which applications can access the Linux functions
• How to automate toil for site reliability engineers (SREs)
• Best practices for making container images more secure, scalable and manageable

Question 4. Which of the following standards are required for building a universal application image (UAI)?

• Image is based on a Red Hat Universal Base Image (UBI)
• Image contains license files
• Image is tagged with a unique version number
• Application must implement a Health endpoint
• All of the above

Question 5. What is the primary purpose of the GitHub web hook created by the Cloud-Native Toolkit?

• Increments the version tag
• Creates a new OpenShift project
• Re-starts the pods associated with the deployment
• Triggers the current pipeline to run
• Performs unit tests on the application source

Question 6. Which command creates and configures your Red Hat OpenShift project for use with the Cloud-Native Toolkit?

• oc login
• oc sync
• oc status
• oc pipeline
• oc start

Question 7. What is the recommended way to provide service credentials to your deployed application?

• Hard coded in source
• An ENV file stored in the source directory
• Config maps
• Secrets
• Never use credentials in deployments

Question 8. What tool from the Cloud-Native Toolkit performs code coverage tests on application source?

• SonarQube
• Artifactory
• Image Registry
• Argo CD
• Lint

Question 9. What is the primary purpose for security context constraints (SCCs)?

• Enables OpenShift cluster administrators the ability to provide containers unlimited access to an OpenShift cluster
• Enables OpenShift cluster administrators the ability to prevent user access to OpenShift resources
• Enables OpenShift cluster administrators the ability to authorize container permissions
• Enables OpenShift cluster administrators the ability to set limits on user accounts
• Enables OpenShift cluster administrators the ability to make containers more isolated

Question 10. How are security context constraints (SCCs) associated with deployments?

• Via the RBAC user account that created the Deployment resource
• Via an RBAC service account specified by the Pod resource
• The OpenShift administrator assigns the SCC to the Deployment resource
• Via the project the Deployment resource is created in
• The OpenShift administrator assigns the SCC to the project

Question 11. How do deployments request additional permissions?

• With a Security Context specified in the deployment manifest
• A superuser account deploys the container
• A cluster administrator deploys the container
• With environment variables specified in the deployment manifest
• Deploy the container as a privileged container

Question 12. Which of the following is NOT an SCC permission type?

• Privileges
• Projects
• Access Controls
• Capabilities

Question 13. What types of permissions can be requested with a Security Context?

• Run as a specific user
• Perform Linux commands
• Run as a specific group
• Run as a privileged container
• All of the above

Question 14. Which statement is not true about operators?

• An operator is a Kubernetes application
• An operator extends Kubernetes
• An operator runs in the control plane
• An operator manages a backend service
• An operator automates an SRE’s toil

Question 15. Which technology is not one typically used to implement operators?

• Helm
• Ansible
• Terraform
• Go

Question 16. Which capability is not one of the Operator Capability Levels?

• Basic install
• Seamless upgrades
• Full lifecycle
• Deep insights
• Machine learning

Question 17. Which component is the heart of an operator’s structure?

• Controller
• Operand
• Hybrid cloud
• Operator Hub
• StatefulSet

Question 18. Which component tells the operator to reconcile?

• Custom resource
• Custom resource definition
• Controller manager
• Operand
• Service account
