                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q13-Q18):

                                    NEW QUESTION # 13
                                    What is the open source engine for Oracle Functions?

                                    Answer: A

                                    Explanation:
                                    The Fn Project is an open source serverless computing platform that serves as the engine for Oracle Functions. It provides a runtime environment for executing functions in a serverless architecture. The Fn Project enables developers to build and deploy functions using different programming languages, including Java, Python, Node.js, and more. The Fn Project is designed to be flexible and extensible, allowing developers to define functions as small units of code and execute them in response to events or triggers. It supports event- driven execution, allowing functions to be triggered by various events such as HTTP requests, messages from messaging systems, or changes in data. Oracle Functions leverages the Fn Project as its underlying engine, providing a managed serverless platform within the Oracle Cloud Infrastructure. It allows developers to easily develop, deploy, and manage functions using the familiar Fn Project framework and tooling. With Oracle Functions, developers can focus on writing their function code while leaving the infrastructure management, scaling, and operational tasks to the platform.


                                    NEW QUESTION # 14
                                    You are building a container image and pushing it to Oracle Cloud Infrastructure Registry (OCIR). You need to ensure that these images never get deleted from the repository. Which action should you take?

                                    Answer: B

                                    Explanation:
                                    To prevent images from being deleted from a repository, you can set the global policy of image retention to
                                    "Retain All Images". This policy applies to all repositories in the tenancy and overrides any individual repository settings. You can also lock the policy to prevent any changes to it.Verified References: Using Retention Rules to Preserve Data


                                    NEW QUESTION # 15
                                    You have a containerized application that requires access to an Autonomous Transaction Processing (ATP) Database. Which option is NOT valid when the container is deployed in an OKE cluster? (Choose the best answer.)

                                    Answer: D

                                    Explanation:
                                    The option that is not valid for connecting to an Autonomous Transaction Processing (ATP) Database from a container in Kubernetes is: Install the Oracle Cloud Infrastructure Service Broker on the Kubernetes cluster and deploy ServiceInstance and ServiceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest. The Oracle Cloud Infrastructure Service Broker is not used for connecting to an ATP Database from a container in Kubernetes. The Service Broker is used for provisioning and managing cloud services directly from Kubernetes. It allows you to create and manage instances of OCI services using Kubernetes resources like ServiceInstance and ServiceBinding. To connect to an ATP Database from a container in Kubernetes, you can use one of the following valid options: Enable Oracle REST Data Services for the required schemas and connect via HTTPS. This involves enabling and configuring Oracle REST Data Services (ORDS) for the schemas in the ATP Database. You can then connect to the ATP Database using RESTful endpoints provided by ORDS. Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime. This approach involves configuring the necessary environment variables on the container to provide the ATP instance OCID and OCI API credentials. The application can then use the OCI SDK or REST API (such as the CreateConnection endpoint) to establish a connection to the ATP Database. Create a Kubernetes secret with contents from the instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest. This method involves creating a Kubernetes secret that contains the necessary credentials from the ATP Database ' s instance wallet files. The secret can then be mounted as a volume in the application deployment, allowing the application to access the required credentials for connecting to the ATP Database. Both options 1 and 3 provide valid approaches for connecting to an ATP Database from a container in Kubernetes, depending on the specific requirements and preferences of the application.


                                    NEW QUESTION # 16
                                    Your organization requires automatic rotation of third-party API keys stored as secrets in OCI Vault every 90 days. You have created a custom serverless OCI Function named rotate-api-keys that handles the API key generation and updates. You are now configuring the automatic rotation properties of the OCI Vault secret via the OCI API. Which configuration must you specify on the secret to automatically run this custom OCI Function at the required interval?

                                    Answer: B

                                    Explanation:
                                    OCI Vault natively supports scheduled secret rotation and integration with OCI Functions. The RotationConfig model contains is_scheduled_rotation_enabled, rotation_interval, and target_system_details.
                                    Oracle specifies that enabling scheduled rotation requires a rotation interval represented using ISO 8601 duration syntax, so P90D expresses 90 days. For Function-based rotation, the target system is configured as a Function and the target details identify the Function OCID. Oracle further states that Secret Service invokes the configured rotation function as part of the rotation process. A SecretExpiryRule controls expiration rather than scheduled function-based rotation, while Monitoring alarms and Events rules would introduce separate orchestration rather than use Vault ' s native feature. Therefore, A correctly configures automatic 90-day Function-based rotation.


                                    NEW QUESTION # 17
                                    When creating an alarm query in the OCI Monitoring service, which MQL trigger rule evaluates the lack of incoming raw metric data points as the trigger criteria?

                                    Answer: A

                                    Explanation:
                                    OCI Monitoring provides anabsencetrigger for alarms that must fire when a metric stops emitting data. Oracle
                                    ' s current documentation states that an absence alarm uses the MQL absent() statistic. It returns 1 when the metric is absent for the complete evaluation interval and 0 when data is present. An expression can therefore take the form CpuUtilization[1m].absent() or use groupBy() before absent() when separate dimensional streams must be evaluated. A threshold trigger, by contrast, evaluates numeric metric values against limits such as greater than 90 percent. missing and non-zero are not OCI Monitoring trigger-rule names for the required behavior. Thus, the correct trigger rule for detecting a lack of incoming metric data is absence.
