                                                        NEW QUESTION # 64
                                                        Which protocol or mechanism does the Docker client use by default to communicate with the Docker daemon when both are running on the same local host?

                                                        Answer: D

                                                        Explanation:
                                                        In the Linux/Unix environment normally assumed for OCI container development, the Docker client communicates with the locally running Docker daemon through a UNIX domain socket. Docker ' s default endpoint on Linux is unix:///var/run/docker.sock. This allows local inter-process communication without requiring a TCP network connection. TCP can be configured when the client must communicate with a daemon through a network, while SSH can provide secure access to a remote Docker daemon. RPC is not the default Docker client transport. Therefore, for a Docker client and daemon running locally on a Linux-based OCI development host, Local UNIX Sockets is the correct answer. On Windows, Docker uses a named pipe by default, so the answer is specifically applicable to the Linux/Unix OCI context.


                                                        NEW QUESTION # 65
                                                        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: D

                                                        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 # 66
                                                        Kubernetes includes various elements such as compute, network, and storage. Compute is essentially CPU (units) and memory (bytes). Within an OKE cluster, what is considered to be the smallest unit of deployment with respect to compute?

                                                        Answer: A

                                                        Explanation:
                                                        A pod is the smallest and simplest unit in the Kubernetes object model that you create or deploy2. A pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When you create a pod, you define how much CPU and memory (RAM) each container needs. A pod can also include storage volumes, IP addresses, options that govern how the container(s) should run, and more2. Pods are the basic building blocks of larger Kubernetes constructs such as deployments, replica sets, and services2.


                                                        NEW QUESTION # 67
                                                        What is the maximum execution time of Oracle Functions?

                                                        Answer: D

                                                        Explanation:
                                                        The maximum execution time of Oracle Functions is 300 seconds, which is equivalent to 5 minutes. This means that a function running within Oracle Functions cannot exceed a runtime of 5 minutes. If a function requires longer execution times, alternative approaches such as invoking external services asynchronously or using long-running processes should be considered. It is important to design functions with this execution time limitation in mind to ensure optimal performance and efficiency within the Oracle Functions platform.


                                                        NEW QUESTION # 68
                                                        Which term describes an individual set of aggregated data for a metric with zero or more dimension values in the Oracle Cloud Infrastructure (OCI) Monitoring service?

                                                        Answer: D

                                                        Explanation:
                                                        Oracle Monitoring formally defines ametric streamas an individual set of aggregated data for a metric with zero or more dimension values. Different dimension combinations create distinct streams. For example, CPU utilization emitted for two separate Compute instance OCIDs can constitute two separate metric streams because the resourceId dimension differs. A metric namespace identifies the service or application emitting the metrics, such as oci_computeagent. A datapoint is an individual timestamped value within a metric stream. Oracle also uses the term metric group for limit calculations, defining it as the combination of a metric, namespace, and tenancy; that is different from the dimension-specific time-series data described in the question. Therefore, option A exactly matches Oracle ' s documented Monitoring terminology.
