Question 21

You have a containerized app that requires an Autonomous Transaction Processing (ATP) Database. Which option is not valid for o from a container in Kubernetes?

A.EnableOracle REST Data Services for the required schemas and connect via HTTPS.
B.Create a Kubernetes secret with contents from the instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest.
C.Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID, and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime.
D.Install the Oracle Cloud Infrastructure Service Broker on the Kubernetes cluster and deploy serviceinstance and serviceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest.

Correct Answer: A

Explanation
The Kubernetes documentation lays out the following use case for the Service Catalog API:
An application developer wants to use message queuing as part of their application running in a Kubernetes cluster. However, they do not want todeal with the overhead of setting such a service up and administering it themselves. Fortunately, there is a cloud provider that offers message queuing as a managed service through its service broker.
A cluster operator can setup Service Catalog and use itto communicate with the cloud provider's service broker to provision an instance of the message queuing service and make it available to the application within the Kubernetes cluster. The application developer therefore does not need to be concerned withthe implementation details or management of the message queue. The application can simply use it as a service.
The samples in theOCI Service Broker source code include a deployment YAML file that describes how to use an init container to take the values in the Autonomous Transaction Processing service binding and put them in environment variables or in a volume mount. After that, your application can use those values to connect to the database.
Once you've installed and registered the service broker, you're ready to use the ATP service plan to provision an ATP instance. I'll go into details below, but the overview of the process looks like so:
-Create a Kubernetes secret with a new admin and wallet password (in JSON format)
- Create a YAML configuration for the ATP Service Instance
- Deploy the Service Instance
- Create a YAML config for the ATP Service Binding
- Deploy the Service Binding to obtain which results in the creation of a new Kubernetes secret containing the wallet contents
- Create a Kubernetes secret for Microservice deployment use containing the admin password and the wallet password (in plain text format)
- Create a YAML config for the Microservice deployment which uses an initContainer to decode the wallet secrets (due to a bug which double encodes them) and mounts the wallet contents as a volume References:

Question 25

You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIs to POST messages to a stream in the OCI Streaming service.
Which statement is incorrect?
