                                    NEW QUESTION # 85
                                    Which TWO are part of the Cloud Native Computing Foundation (CNCF) container runtime? (Choose two.)

                                    Answer: A,D

                                    Explanation:
                                    The two components that are part of the Cloud Native Computing Foundation (CNCF) container runtime are:
                                    containerd: containerd is an open-source container runtime that provides a runtime environment for containers, including managing container images, executing containers, and handling container lifecycle events. It is designed to be lightweight and extensible, providing the necessary functionality to run containers efficiently. runc: runc is a lightweight container runtime that serves as a reference implementation of the Open Container Initiative (OCI) runtime specification. It is responsible for launching and managing containers based on OCI specifications, including handling container isolation, namespaces, cgroups, and other low-level container operations. These two components, containerd and runc, are widely used in the container ecosystem and are part of the CNCF ' s efforts to promote and develop open-source technologies for cloud-native computing.


                                    NEW QUESTION # 86
                                    Which credential type is required to act as the password when authenticating the Docker CLI to Oracle Cloud Infrastructure Registry?

                                    Answer: B

                                    Explanation:
                                    Oracle Container Registry requires an OCI Auth Token when Docker prompts for the password during docker login. Oracle explicitly documents that the user first generates an auth token under the OCI user profile, then supplies the tenancy namespace and username as the Docker username and the auth token as the password. A Console password is intended for interactive OCI Console authentication and is not the Docker Registry credential. API signing keys authenticate signed OCI API requests used by the CLI, SDKs, and related tools, while Customer Secret Keys are associated with Object Storage compatibility APIs. Consequently, the programmatic credential designed specifically to serve as the Docker Registry password is the OCI Auth Token.


                                    NEW QUESTION # 87
                                    Your organization is transitioning a monolithic billing system into a cloud-native microservices application deployed on Oracle Cloud Infrastructure Container Engine for Kubernetes. To maintain high operational excellence under the observability pillar of cloud-native development, the engineering team has successfully set up centralized log aggregation and system metrics. However, you must now implement a solution that can track, visualize, and analyze end-to-end transaction flows and asynchronous call hops across multiple distributed microservices.
                                    Which service should be integrated to fulfill this distributed transaction tracing requirement?

                                    Answer: D

                                    Explanation:
                                    OCI Application Performance Monitoring is specifically designed fordistributed tracingof application transactions across multiple components and services. Oracle states that APM collects and processes trace and span data, allowing administrators to analyze transaction performance, latency, volume, and errors across distributed applications. Trace Explorer can visualize traces containing multiple spans and help identify bottlenecks as requests move between services, databases, functions, and asynchronous components. OCI Monitoring concentrates primarily on metric streams, while Logging Analytics focuses on log aggregation and analysis. Service Mesh can provide service-to-service traffic telemetry and may participate in observability, but APM is the service designed to collect, correlate, and analyze distributed transaction traces.
                                    Therefore, D directly satisfies the end-to-end tracing requirement.


                                    NEW QUESTION # 88
                                    What is the maximum execution time of Oracle Functions?

                                    Answer: A

                                    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 # 89
                                    Which node configuration in Oracle Cloud Infrastructure Container Engine for Kubernetes provides a serverless experience with granular pod-level elasticity and billing?

                                    Answer: D

                                    Explanation:
                                    OKE Virtual Nodes provide Oracle ' s serverless Kubernetes execution model. Oracle manages the underlying node infrastructure, eliminating the need for customers to provision, patch, upgrade, scale, or troubleshoot conventional worker-node infrastructure. Resource allocation and elasticity occur at the pod level, allowing workloads to scale without planning the capacity of a conventional node pool. Oracle also describes Virtual Nodes as providing pay-per-use pricing based on the compute resources consumed by each Kubernetes pod rather than charging for entire worker servers that might contain unused capacity. Managed, bare metal, and self-managed nodes remain infrastructure-oriented worker-node models and therefore do not provide the same serverless pod-level operating model. Consequently, Virtual Nodes are the configuration designed for granular elasticity and pod-oriented consumption.
