                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q150-Q155):

                                    NEW QUESTION # 150
                                    Which statement is NOT valid regarding custom metrics and the OCI Monitoring PostMetricData API?

                                    Answer: A

                                    Explanation:
                                    Statement C is invalid because Oracle permits custom metrics to be postedas frequently as every second. The one-minute value applies to the minimum aggregation interval when metric data is subsequently queried, not to the ingestion frequency. Oracle also verifies the remaining statements. PostMetricData requires timestamps to be less than two hours in the past and less than ten minutes in the future. Custom namespaces must not use reserved prefixes such as oci_ or oracle_. The API additionally allows a maximum of 20 dimensions per metric group in a single posting operation. Therefore, interpreting one minute as the minimum interval between raw metric submissions incorrectly confuses ingestion frequency with Monitoring ' s aggregation
                                    /query interval. Option C is consequently the NOT valid statement.


                                    NEW QUESTION # 151
                                    In the shared responsibility model, who should perform patching, upgrading, and maintaining of the worker nodes in provisioned Oracle Container Engine for Kubernetes (OKE) clusters?

                                    Answer: A

                                    Explanation:
                                    In the shared responsibility model, Oracle is responsible for securing the underlying cloudinfrastructure and platform services, while customers are responsible for securing theirdata and applications within the cloud4. For provisioned OKE clusters, Oracle manages the control plane (master nodes) of the Kubernetes cluster, while customers manage the data plane (worker nodes) of the cluster5. Therefore, it is the responsibility of the customer to perform patching, upgrading, and maintaining of the worker nodes in provisioned OKE clusters5. Customers can use tools such as Terraform or kubectl to automate these tasks5.


                                    NEW QUESTION # 152
                                    A service you are deploying to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) uses a docker image from a private repository in OCI Registry (OCIR). Which configuration is necessary to provide access to this repository from OKE?

                                    Answer: A

                                    Explanation:
                                    The necessary configuration to provide access to a private repository in OCI Registry (OCIR) from OCI Container Engine for Kubernetes (OKE) is to create a docker-registry secret for OCIR with an identity Auth Token on the cluster and specify the imagePullSecret property in the application deployment manifest. Here ' s the breakdown of the steps: Create a docker-registry secret for OCIR with an identity Auth Token: In order to authenticate with the private repository in OCIR, you need to create a secret in your OKE cluster that contains the necessary credentials. This can be done by generating an identity Auth Token from the OCI Console and creating a secret in the cluster using the kubectl command. Specify the imagePullSecret property in the application deployment manifest: In your application ' s deployment manifest (such as a Kubernetes Deployment or StatefulSet YAML file), you need to include the imagePullSecret property and specify the name of the secret you created in the previous step. This allows the OKE cluster to use the credentials from the secret to pull the docker image from the private repository in OCIR during deployment. By following these steps, you can ensure that your OKE cluster has the necessary access to the private repository in OCIR, and your application can successfully pull the required docker image during deployment.


                                    NEW QUESTION # 153
                                    What is the correct username format required for the docker login command when authenticating to Container Registry for an IAM user belonging to a non-default identity domain?

                                    Answer: D

                                    Explanation:
                                    Oracle Container Registry authentication requires the tenancy namespace to precede the identity information supplied to Docker. Oracle documents the standard username format as < tenancy-namespace > / < username
                                    > . When an identity domain or federated domain must be identified explicitly, the domain name is inserted between the tenancy namespace and the username, resulting in < tenancy-namespace > / < domain-name > / < username > . The corresponding OCI Auth Token is supplied as the Docker password. Options C and D incorrectly rearrange the tenancy namespace and domain components, while option A omits the required domain qualification for the scenario described. Therefore, option B correctly represents the qualified Docker login username format used when the user ' s identity must be associated with a non-default domain.


                                    NEW QUESTION # 154
                                    Which technique is used for testing the entire user flow as well as the moving parts of a cloud native app, ensuring that there are no high-level discrepancies?

                                    Answer: C

                                    Explanation:
                                    End-to-end testing is a technique that involves checking the entire user flow as well as the moving parts of a cloud native app, ensuring that there are no high-level discrepancies3. End-to-end testing simulates real user scenarios and validates the functionality, performance, reliability, and security of the app from start to finish3. End-to-end testing has several benefits, such as3:
                                    * Comprehensive testing: You can test your app as a whole and verify that all the components work together as expected.
                                    * User-centric testing: You can test your app from the user's perspective and ensure that it meets the user' s needs and expectations.
                                    * Quality assurance: You can test your app in a realistic environment and identify any issues or defects before releasing it to the users.
