  C. Both old and new application versions are deployed to production at the same time.

• Question 54:

  A developer has created another version of a microservice and wants 10% of the traffic to flow towards it for testing purposes. The application is already configured using OCI (Oracle Cloud Infrastructure) Service Mesh. Which of the following steps is the right approach to achieve this goal?

  A. Create a new Kubernetes deployment for the new version of the microservice and set the traffic splitting percentage to 10% in the Kubernetes service manifest.
  B. Use Kubernetes HPA (Horizontal Pod Autoscaler) to scale the new version of the microservice to handle 10% of the traffic automatically.
  C. Create a new entry in the routeRules field of the ingress gateway route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.
  D. Create a new entry in the routeRules field of the virtual service route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.
  D. Create a new entry in the routeRules field of the virtual service route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.

• Question 57:

  Your team has been tasked with debugging a Cloud Native application developed using the following Oracle Cloud Infrastructure (OCI) services: Object Storage, Events, Functions, API Gateway, and Autonomous Database. Which of these is NOT a valid option for troubleshooting issues in OCI? (Choose the best answer.)

  A. View service metric information from the OCI Monitoring service.
  B. Configure the application to send logs to the OCI Logging service.
  C. Use OCI Service Connector Hub to configure a service connector to automatically send logs to the OCI Logging Analytics service.
  D. Trace performance issues In the Application Performance Monitoring service by enabling Function traces.
  E. Leverage OCI Cloud Guard to extract and visualize the debug logs generated by your application.
  D. Trace performance issues In the Application Performance Monitoring service by enabling Function traces.

• Question 58:

  You have two microservices, A and B running in production. Service A relies on APIs from service

  B. You want to test changes to service A without deploying all of its dependencies, which includes service

  B. Which approach should you take to test service A?

  A. Test using a previous test version of service
  C. Test using the current production version of service
  D. This is not possible because service B is a dependency.
  B

• Question 59:

  Which option best defines microservices?
