                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q38-Q43):

                                    NEW QUESTION # 38
                                    Which of the following is NOT a criterion that is usually met by a microservice?

                                    Answer: B

                                    Explanation:
                                    The correct answer is: " Tightly coupled. " Tightly coupling is not a criterion that is usually met by a microservice. In fact, microservices are designed to be loosely coupled. Loosely coupling refers to reducing dependencies and minimizing the direct interactions between different components or services. Microservices promote independence and autonomy, allowing each service to operate independently without being tightly bound to other services. The other options listed are criteria that are typically met by microservices:
                                    Organized around business capabilities: Microservices architecture suggests designing services around specific business capabilities or functionalities. This allows for focused and specialized services that align with the organization ' s business needs. Independently deployable: Microservices are designed to be independently deployable units. Each microservice can be developed, tested, and deployed separately, without impacting other services. This enables agility and scalability in the deployment process. Highly maintainable:
                                    Microservices are often designed to be highly maintainable. They are smaller in scope and focused on specific tasks, making it easier to manage and maintain individual services. Additionally, microservices can be updated, patched, or replaced without affecting the entire system, facilitating easier maintenance and evolution of the application. Therefore, the criterion that is NOT typically met by a microservice is being tightly coupled.


                                    NEW QUESTION # 39
                                    Which TWO statements are true for serverless computing and serverless architectures? (Choose two.)

                                    Answer: C,D

                                    Explanation:
                                    The two true statements for serverless computing and serverless architectures are: Applications running on a FaaS (Functions as a Service) platform: Serverless architectures typically involve running code in the form of functions on a serverless platform. These functions are event-driven and executed in response to specific triggers or events. Serverless function execution is fully managed by a third party: In serverless computing, the cloud provider takes care of the infrastructure management and resource provisioning. The execution of serverless functions is handled automatically by the platform, relieving developers from the responsibility of managing servers or infrastructure. It ' s important to note that long running tasks are not typically suited for serverless architectures due to the event-driven nature of serverless functions. Also, while serverless functions may have state, it is recommended to avoid external storage dependencies and instead leverage stateless functions whenever possible. Additionally, scaling in serverless architectures is typically handled automatically by the platform, rather than being the responsibility of the application DevOps team.


                                    NEW QUESTION # 40
                                    You have built a custom container image for your microservice and successfully pushed it to Oracle Cloud Infrastructure Registry (OCIR). Which OCI CLI command should you run to cryptographically sign the pushed image using a master encryption key managed in OCI Vault and upload the resulting signature?

                                    Answer: D

                                    Explanation:
                                    Oracle explicitly documents oci artifacts container image-signature sign-upload for signing a Container Registry image and uploading its image signature. The operation requires the image OCID, compartment OCID, Vault master encryption key OCID, key-version OCID, and an approved RSA signing algorithm such as SHA_256_RSA_PKCS_PSS. Container Registry image-management commands are organized under the OCI CLI artifacts container command group, which is why the other command paths are invalid. container- engine relates to OKE rather than image-signature creation, and there is no container-registry image-signature top-level CLI group. Oracle ' s Container Registry documentation provides the exact command shown in option B for signing an already-pushed image using a key stored in OCI Vault.


                                    NEW QUESTION # 41
                                    Which token authentication policy configuration parameter should be defined when adjusting for potential clock synchronization differences between the external OAuth2 identity provider and the OCI API Gateway?

                                    Answer: D

                                    Explanation:
                                    maxClockSkewInSeconds specifies the maximum expected difference between the system clock of the token issuer and the OCI API Gateway. Oracle documents this value as part of token/JWT authentication policy configuration. The gateway accounts for the configured skew when evaluating time-dependent JWT claims such as nbf (not before) and exp (expiration), preventing otherwise valid tokens from being rejected because of minor clock differences between systems. Oracle currently documents a valid range from 0 through 120 seconds for the JWT policy. maxCacheDurationInHours controls caching behavior rather than clock synchronization, while SSL verification relates to certificate validation. allowedClockVariance is not the documented OCI API Gateway property. Therefore, B is the correct configuration parameter.


                                    NEW QUESTION # 42
                                    What can you use to dynamically make Kubernetes resources discoverable to public DNS servers? (Choose the best answer.)

                                    Answer: B

                                    Explanation:
                                    To dynamically make Kubernetes resources discoverable to public DNS servers, you can use ExternalDNS.
                                    ExternalDNS is a Kubernetes add-on that automates the management of DNS records for your Kubernetes services and ingresses. It can be configured to monitor the changes in your Kubernetes resources and automatically update DNS records in a supported DNS provider. By integrating ExternalDNS with your Kubernetes cluster, you can ensure that the DNS records for your services and ingresses are automatically created, updated, or deleted based on changes in your Kubernetes resources. This allows your Kubernetes resources to be discoverable by external systems through public DNS servers.
