                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q151-Q156):

                                    NEW QUESTION # 151
                                    Which annotation is required in a Kubernetes Service manifest of type LoadBalancer to provision a private load balancer rather than a public load balancer?

                                    Answer: B

                                    Explanation:
                                    Oracle ' s OKE documentation explicitly specifies the annotation service.beta.kubernetes.io/oci-load-balancer- internal: " true " when a Kubernetes Service of type LoadBalancer must provision an internal OCI Load Balancer with a private IP address. The annotation is placed in the Service manifest ' s metadata.annotations section. If an alternative subnet must host the private load balancer, Oracle allows an additional subnet annotation, but the oci-load-balancer-internal setting remains the control that requests internal rather than public exposure. The annotation names in B, C, and D are not the documented OCI Load Balancer annotations for this purpose. Therefore, option A is the required configuration for creating a private/internal OCI Load Balancer through an OKE Kubernetes Service manifest.


                                    NEW QUESTION # 152
                                    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,B,C

                                    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 # 153
                                    You are building a secure containerized application on Container Engine for Kubernetes (OKE) that must access OCI resources securely using OKE Workload Identity. Which cluster type must you select during creation to enable support for OKE Workload Identity?

                                    Answer: C

                                    Explanation:
                                    OKE Workload Identity is anenhanced-cluster capability. Oracle ' s current Kubernetes Engine documentation explicitly lists workload identity as supported by Enhanced clusters and not supported by Basic clusters.
                                    Workload Identity enables IAM policies to authorize individual Kubernetes workloads according to attributes such as cluster, namespace, and service account, avoiding broader permissions inherited from worker-node instance principals. Basic clusters support standard Kubernetes and OKE functionality but exclude enhanced capabilities including Workload Identity, virtual nodes, self-managed nodes, and advanced cluster add-on management. "Dedicated cluster" and "Autonomous cluster" are not the OKE cluster types used for this feature classification. Therefore, an application architecture requiring OKE Workload Identity must use an Enhanced cluster, making option A correct.


                                    NEW QUESTION # 154
                                    Which matching behavior occurs when an Oracle Cloud Infrastructure (OCI) Events rule condition defines an attribute value containing only a single asterisk (*) wildcard?

                                    Answer: A

                                    Explanation:
                                    Oracle ' s Events filtering documentation explicitly defines the behavior of a standalone asterisk wildcard.
                                    When an attribute value consists only of *, it matchesall values for that attribute except null. The field must therefore exist and contain a non-null value for the rule condition to match. Oracle permits wildcard characters only in attribute values, and an asterisk can otherwise appear at the beginning, middle, or end of a value pattern. It is not interpreted as a literal asterisk in this context, nor is it restricted to matching empty strings. Option A is incorrect because null values are excluded. Therefore, option B precisely reflects Oracle ' s documented Events rule wildcard semantics.


                                    NEW QUESTION # 155
                                    A developer using Oracle Cloud Infrastructure (OCI) API Gateway needs to authenticate the API requests to their web application. The authentication process must be implemented using a custom scheme which accepts string-based parameters from the API caller. Which approach should the developer use in this scenario?

                                    Answer: C

                                    Explanation:
                                    In the given scenario, the developer should use the approach of creating an authorizer function using token- based authorization. Token-based authorization is a commonly used approach for authenticating API requests.
                                    It involves generating and issuing tokens to API callers, which they can then include in the requests they make to the API. The tokens serve as proof of authentication and are validated by the server to ensure the caller ' s identity and access rights. By creating an authorizer function using token-based authorization, the developer can implement a custom scheme that accepts string-based parameters from the API caller. This allows the developer to define their own authentication logic and validate the provided tokens according to their requirements. The authorizer function can be configured in the OCI API Gateway to be invoked before forwarding the request to the web application. It will perform the necessary token validation and authentication checks, allowing only authorized requests to access the protected resources of the web application.
