Course Name:- Hybrid Cloud Conference – Backend Services for Containers
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
- Never use credentials in deployments
Question 8. What tool from the Cloud-Native Toolkit performs code coverage tests on application source?
- Image Registry
- Argo CD
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?
- Access Controls
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?
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?
- Hybrid cloud
- Operator Hub
Question 18. Which component tells the operator to reconcile?
- Custom resource
- Custom resource definition
- Controller manager
- Service account
