                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q119-Q124):

                                    NEW QUESTION # 119
                                    You want to push a new image in the Oracle Cloud Infrastructure (OCI) Registry. Which TWO actions would you need to perform? (Choose two.)

                                    Answer: A,C

                                    Explanation:
                                    To push a new image to the Oracle Cloud Infrastructure (OCI) Registry, you would need to perform the following two actions: Assign a tag via Docker CLI to the image: Before pushing the image, you need to assign a tag to it using the Docker CLI. The tag helps identify the image and associate it with a specific version or label. Generate an auth token to complete the authentication via Docker CLI: To authenticate and authorize the push operation, you need to generate an auth token. This token is used to authenticate your Docker CLI with the OCI Registry, allowing you to push the image securely. Note: Generating an API signing key, assigning an OCI defined tag via OCI CLI, and generating an OCI tag namespace are not required steps for pushing a new image to the OCI Registry.


                                    NEW QUESTION # 120
                                    Your organization is deploying a high-performance distributed deep learning training workload that requires GPU-enabled bare metal Compute instances connected through an ultra-low-latency Oracle Cloud Infrastructure (OCI) RDMA cluster network. To maximize processing efficiency and comply with strict corporate OS requirements, your team must use a custom, pre-hardened Oracle Linux operating system image that is not supported by default node pools. The containerized training jobs must be orchestrated and scheduled using your existing Container Engine for Kubernetes (OKE) control plane.
                                    Which worker node deployment model must you implement?

                                    Answer: D

                                    Explanation:
                                    OKE Self-Managed Nodes, also called Bring Your Own Nodes, provide the necessary infrastructure flexibility for specialized Compute workloads. Oracle states that self-managed nodes are Compute instances that customers create themselves and then attach to an enhanced OKE cluster. Because the instances are provisioned through OCI Compute rather than a managed OKE node pool, organizations can select specialized shape and image combinations unavailable to managed or virtual nodes. Oracle specifically cites GPU shapes, HPC shapes, and high-bandwidth, ultra-low-latency RDMA cluster networks as examples suited to self-managed nodes. This model also enables custom operating-system configuration. Virtual Nodes abstract the infrastructure entirely, while Managed Node Pools constrain supported infrastructure combinations. Therefore, Self-Managed Nodes satisfy all of the stated GPU, RDMA, and custom-image requirements.


                                    NEW QUESTION # 121
                                    What can you use to dynamically make Kubernetes resources discoverable to public DNS servers? (Choose the best answer.)

                                    Answer: C

                                    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.


                                    NEW QUESTION # 122
                                    Your organization has mandated strict IAM policy isolation for microservices accessing an Oracle Cloud Infrastructure (OCI) Queue named payment-queue in a compartment named prod-payment-compartment. A producer microservice deployed on an OCI Compute instance needs to publish transaction messages into the queue, but corporate security dictates that this microservice must not have permission to view queue configurations, delete queues, or read/consume messages. You have created a dynamic group named payment- producer-dg that contains the Compute instance hosting the producer microservice.
                                    Which IAM policy statement must you write to satisfy this security requirement with the least privilege?

                                    Answer: C


                                    NEW QUESTION # 123
                                    You are developing a distributed application and you need a call to a path to always return a specific JSON content deploy an OCI API Gateway with the below API deployment specification. What is the correct value for type? { " routes " : [{ " path " : " /hello " , " methods " : [ " Get " ), " backend " : { " type " : " ----------------
                                    " , " status " : 200, " headers " : [{ " name " : " Content-Type " , " value " : " application/json " }] " body " : "
                                    {\ " myjson\ " : \ " consistent response\ " } " }}]}

                                    Answer: D

                                    Explanation:
                                    The correct value for the " type " field in the API deployment specification is " STOCK_RESPONSE_BACKEND " . By setting the " type " to " STOCK_RESPONSE_BACKEND " , you are indicating that the backend for the specified route should return a pre-defined response. This type of backend is commonly used when you want a specific response to be returned consistently, regardless of the actual backend service implementation. In this case, the API deployment specification is configured to have a single route with the path " /hello " and the method " GET " . The backend section specifies the type as " STOCK_RESPONSE_BACKEND " . Additionally, it defines the response status code as 200, sets the " Content-Type " header to " application/json " , and provides the JSON content in the " body " field. Using this configuration, any request to the " /hello " path with the " GET " method will always receive a consistent JSON response with the content " { " myjson " : " consistent response " } " .
