Question 2

You are planning the migration of a legacy monolithic billing application to a cloud-native architecture on Oracle Cloud Infrastructure. The application currently relies on a centralized relational database and synchronous local procedure calls, and you must address the primary architectural challenges associated with transitioning to a distributed microservices model.
Which TWO statements represent valid engineering challenges or design strategies that must be considered during this cloud-native migration?

A. Implementing microservices requires adopting eventual consistency patterns, such as the Saga pattern, because distributed databases cannot easily maintain synchronous transactions across service boundaries. B. Monolithic databases migrated to OCI Object Storage will automatically scale horizontally and support distributed transactions natively for all microservices. C. Cloud-native microservices must communicate using synchronous REST APIs exclusively, as asynchronous event-driven communication is not supported within OCI. D. By default, OCI ensures that all distributed containerized microservices automatically share a single, global transaction state across different compartments without any application-level coding. E. Transitioning to microservices increases the operational complexity of the application, necessitating centralized logging and distributed tracing to troubleshoot service-to-service communication.

Question 3

In the DevOps lifecycle, what is the difference between continuous delivery and continuous deployment?
(Choose two.)

A. Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process. B. Continuous delivery requires more automatic linting, while continuous deployment testing must be run manually. C. Continuous delivery involves automation of developer tasks, while continuous deployment involves manual operational tasks. D. Continuous delivery utilizes automatic deployment to a development environment, while continuous deployment involves automatic deployment to a production environment.

Question 5

Which is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service?

A. Publishing all the OCI resource events in a specific compartment to the OCI Streaming service for later analysis. B. Triggering a notification action when a function completes its execution. C. Publishing a notification when long-lived tasks complete, such as an OCI Autonomous Database backup completion. D. Capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances. E. Triggering a function deployed in Oracle Functions when new files are uploaded to an OCI Object Storage bucket.

Question 6

A service you are deploying to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) uses a docker image from a private repository in OCI Registry (OCIR). Which configuration is necessary to provide access to this repository from OKE?

A. Add a generic secret on the cluster containing your identity credentials. Then specify a registryCredentials property in the deployment manifest. B. Create a docker-registry secret for OCIR with API key credentials on the cluster, and specify the imagePullSecret property in the application deployment manifest. C. Create a docker-registry secret for OCIR with identity Auth Token on the cluster, and specify the imagePullSecret property in the application deployment manifest. D. Create a dynamic group for nodes in the cluster, and a policy that allows the dynamic group to read repositories in the same compartment.

Question 9

Your development team wants to configure API Gateway request validation to shield an upstream backend microservice from ill-formed API calls. You want to test the validation rules in your staging environment first without blocking any non-compliant client requests, and you want to ensure the gateway checks that a mandatory HTTP header is present. Which TWO configurations should you apply to your API Gateway deployment specification to meet this requirement?

A. Create a dynamic group and IAM policy to grant the API Gateway permission to inspect incoming request bodies in real-time. B. Set the request validation policy mode to Permissive to log validation failures without rejecting requests. C. Use the request.auth[ < key > ] context variable inside a Stock Response backend to log non-compliant headers. D. Configure the request validation policy with header validations to mandate the presence of the required HTTP header. E. Set the request validation policy mode to Enforcing to forward failed requests to the execution log instead of blocking them.
