                                                        Oracle Cloud Infrastructure Developer Professional Sample Questions (Q141-Q146):

                                                        NEW QUESTION # 141
                                                        You are deploying a set of Java microservices to an Oracle Cloud Infrastructure Container Engine for Kubernetes cluster. You must ensure that the application design strictly adheres to the Twelve-Factor App methodology for configuration management and backing services to simplify multi-environment deployments. Which TWO design strategies must you implement to satisfy these Twelve-Factor App principles?

                                                        Answer: B,E

                                                        Explanation:
                                                        The Twelve-Factor methodology requires configuration to be separated from application code and backing services to be treated as attached resources. Oracle ' s Twelve-Factor guidance specifically recommends keeping configuration outside the Docker image and supplying deployment-specific values through the environment. This allows the same application artifact to move between development, test, and production without rebuilding it. Kubernetes ConfigMaps or environment variables implement this principle effectively.
                                                        The backing-services factor similarly treats databases, queues, caches, and external services as replaceable resources referenced through configuration rather than hardcoded dependencies. Consequently, switching a database or message broker should require configuration changes rather than application-code changes.
                                                        Hardcoding credentials or environment-specific values violates configuration separation, while sharing one database across environments is not required for dev/prod parity. Therefore, B and D are correct.

                                                        Bottom of Form


                                                        NEW QUESTION # 142
                                                        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?

                                                        Answer: B,C

                                                        Explanation:
                                                        OCI dynamic groups identify Compute instances using the documented instance.id attribute, making B valid.
                                                        Oracle Container Registry documentation also shows manage repos as a policy capable of authorizing image pushes within a specified compartment, making D the sufficient policy among the supplied choices. container.
                                                        instance is not a valid Compute-instance matching variable, while inspect repos provides only discovery-level permissions. use repos does not supply the repository update permissions required for pushing images. For stricter production least privilege, Oracle additionally documents conditioning a manage repos policy to specific permissions such as REPOSITORY_READ, REPOSITORY_UPDATE, and REPOSITORY_CREATE; however, that granular variant is not offered among these choices. Therefore, B and D are the correct selections.


                                                        NEW QUESTION # 143
                                                        You are instructed to automate manual tasks and help software teams manage complex environments at scale using the Oracle Cloud Infrastructure (OCI) services. Which THREE OCI services can be leveraged to securely store and version your application ' s source code, and automate the building, testing, and deployment of applications to the OCI platform? (Choose three.)

                                                        Answer: A,E,F

                                                        Explanation:
                                                        The three OCI services that can be leveraged to securely store and version your application ' s source code, and automate the building, testing, and deployment of applications to the OCI platform are: DevOps: OCI provides a comprehensive set of DevOps services, including Oracle Developer Cloud Service, which allows you to manage source code repositories, automate builds and testing, and streamline the deployment process.
                                                        Container Engine for Kubernetes: OCI ' s Container Engine for Kubernetes (OKE) enables you to deploy and manage containerized applications using Kubernetes. It provides a scalable and reliable platform for automating the deployment of your applications. Oracle Cloud Infrastructure Registry: OCI Registry is a fully managed, private container registry that allows you to securely store and manage Docker images. It integrates with other OCI services, such as Container Engine for Kubernetes, to facilitate seamless deployment and orchestration of containerized applications. These services combined provide the necessary tools and infrastructure to support continuous integration and continuous deployment (CI/CD) workflows, enabling efficient and automated application development and deployment processes in the Oracle Cloud Infrastructure environment.


                                                        NEW QUESTION # 144
                                                        You are building an event-driven workflow and need to programmatically create an Oracle Cloud Infrastructure (OCI) Events rule using the OCI Command Line Interface (CLI). Which CLI command correctly creates the rule while sourcing its target destination services from a local configuration file named actions.json?

                                                        Answer: C

                                                        Explanation:
                                                        The OCI CLI command oci events rule create requires the --actions parameter to define the destinations invoked when the Events rule condition matches. Oracle identifies --actions as a required complex parameter and explicitly supports loading its JSON representation from a local file using file://path/to/file. Oracle ' s Events examples show the same pattern: --actions file://actions.json. The other proposed parameters--- destinations, --targets, and --action-payload-are not valid parameters for the events rule create CLI operation. The actions file can define supported destinations such as Notifications, Streaming, or Functions.
                                                        Consequently, option D precisely matches the current OCI CLI command-reference syntax for programmatically creating the rule with action definitions stored in a file.


                                                        NEW QUESTION # 145
                                                        You are deploying a serverless data integration pipeline where an OCI Function needs to consume real-time events from an OCI Stream in the prod-compartment compartment. Your corporate security policy mandates strict least-privilege access, meaning the function must only be permitted to consume (pull) messages, with absolutely no capability to publish (push) messages to the stream. Which TWO configurations are required to establish this granular authorization using a Dynamic Group named analytics-function-dg?

                                                        Answer: A,E

                                                        Explanation:
                                                        Oracle Streaming exposes separate IAM resource types for producers and consumers. Granting use stream- pull provides STREAM_CONSUME, covering operations such as GetMessages, CreateCursor, group cursors, heartbeats, and commits without granting STREAM_PRODUCE. Granting use streams would be broader because that resource type includes both production and consumption capabilities. Oracle Functions can be placed in a dynamic group with a rule using resource.type = ' fnfunc ' together with the Function ' s compartment OCID. compute would not match an Oracle Function resource, and stream-push provides the opposite permission by allowing message publication. Therefore, A establishes consume-only Streaming permission while C correctly associates the Functions resources with the dynamic group.
