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

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

You are developing a continuous integration (CI) pipeline running on an Oracle Cloud Infrastructure (OCI) Compute instance that automatically builds and pushes container images to Container Registry (OCIR). You need to configure dynamic group membership and write the minimum required IAM policies to authorize this Compute instance to push images to repositories within a compartment named qa-compartment.
Which TWO steps must you perform to achieve this authorization?

• A. Create a dynamic group named ci-pipeline-dg with the matching rule: ANY {instance.id = ' ocid1.
  instance.oc1.phx.exampleinstanceocid ' }
• B. Add an IAM policy statement: Allow dynamic-group ci-pipeline-dg to use repos in compartment qa- compartment
• C. Create a dynamic group named ci-pipeline-dg with the matching rule: ANY {container.instance = ' ocid1.instance.oc1.phx.exampleinstanceocid ' }
• D. Add an IAM policy statement: Allow dynamic-group ci-pipeline-dg to manage repos in compartment qa-compartment
• E. Add an IAM policy statement: Allow dynamic-group ci-pipeline-dg to inspect repos in compartment qa- compartment

Which TWO are part of the Cloud Native Computing Foundation (CNCF) container runtime? (Choose two.)

• A. getcd
• B. runc
• C. rkt-o
• D. containerd

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

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. Use Kubernetes HPA (Horizontal Pod Autoscaler) to scale the new version of the microservice to handle 10% of the traffic automatically.
• B. 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.
• C. 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 ingress gateway route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.
