                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q156-Q161):

                                    NEW QUESTION # 156
                                    To effectively test your cloud native applications for " unknown unknowns " , you need to employ various testing and deployment strategies. Which strategy involves exposing new functionality or features to only a small set of users?

                                    Answer: C

                                    Explanation:
                                    The strategy that involves exposing new functionality or features to only a small set of users is called Canary Deployment. Canary deployment is a technique used in software development and deployment where a new version of an application or feature is released to a small subset of users or a specific group of servers. This allows for testing and gathering feedback on the new functionality in a controlled and limited environment before making it available to a wider audience. In a canary deployment, a small portion of the traffic is routed to the new version while the majority of the traffic still goes to the stable version. This allows for monitoring and evaluation of the new functionality in real-world conditions while minimizing the impact of any potential issues or bugs. If the new version performs well and meets the desired criteria, it can then be gradually rolled out to a larger user base or all servers. By exposing the new functionality or features to a small set of users initially, canary deployment helps in identifying any unforeseen issues, gathering feedback, and ensuring the stability and reliability of the application before a full deployment.


                                    NEW QUESTION # 157
                                    You are deploying a containerized database application on a host using the standard Docker engine. To prevent data loss when the container instance is destroyed or updated, you must configure a storage mechanism that isolates application data from the volatile container layer and guarantees persistence. Which TWO statements or approaches correctly describe Docker storage components that satisfy this requirement?

                                    Answer: B,E

                                    Explanation:
                                    Persistent container data must be stored outside the container ' s ephemeral writable layer. Docker volumes provide Docker-managed storage that remains independently available from the lifecycle of an individual container. Bind mounts provide another persistence mechanism by mapping a specified host file or directory directly into the container. Oracle ' s Docker documentation demonstrates both data volumes and host-path mounts for externalizing files from containers and preserving them independently. The writable container layer is removed with the container, a tmpfs mount stores data in volatile memory rather than persistent disk, and Docker image layers are immutable and cannot receive normal runtime database writes. Therefore, Docker volumes and bind mounts are the two valid persistence approaches described.


                                    NEW QUESTION # 158
                                    (CHK_1 > 3) You have an e-commerce application that loads customers ' transactional data into the Oracle Cloud Infrastructure (OCI) Streaming service. The data must now be extracted and transformed before sending it to a third-party REST endpoint. You have been directed to leverage the OCI Service Connector Hub to automate this process. Which configuration option would address this requirement?

                                    Answer: D

                                    Explanation:
                                    To address the requirement of extracting and transforming data from the Oracle Cloud Infrastructure (OCI) Streaming service and sending it to a third-party REST endpoint using the OCI Service Connector Hub, the best configuration option is: Configure a new service connector as follows: * Source: Streaming * Task: None
                                    * Target: Notifications By selecting the Streaming service as the source, you can capture the transactional data from the stream. Since there is a need to transform and send the data to a third-party REST endpoint, you don
                                    ' t need to specify any specific task in the connector. The target is set to Notifications, which allows you to send the transformed data to an endpoint outside of the OCI environment. Notifications can be configured to deliver the data to various supported destinations, including HTTP endpoints, email addresses, and more. This configuration enables you to automate the process of extracting data from the streaming service and sending it to the desired third-party REST endpoint, fulfilling the requirement of extracting, transforming, and forwarding the data.


                                    NEW QUESTION # 159
                                    Which of the following step is NOT required for setting up the Container Engine for Kubernetes (OKE) cluster access using a local installation of kubectl?

                                    Answer: B

                                    Explanation:
                                    The step that is NOT required for setting up the Container Engine for Kubernetes (OKE) cluster access using a local installation of kubectl is to generate an Auth token from the OCI console. The authentication for accessing the OKE cluster using kubectl can be performed using the OCI CLI configuration, specifically the API signing key pair and the kubeconfig file. Here are the correct steps for setting up the OKE cluster access using a local installation of kubectl: Set up the kubeconfig file: The kubeconfig file contains the necessary information to authenticate and access the OKE cluster using kubectl. It includes details such as the cluster endpoint, authentication method, and credentials. Generate an API signing key pair (if you do not already have one) and upload the public key of the API signing key pair: The API signing key pair is used for authentication with the OCI services. The public key of the key pair needs to be uploaded to the OCI Console to associate it with your user account. Install and configure the Oracle Cloud Infrastructure (OCI) CLI: The OCI CLI provides a command-line interface to interact with the OCI services. It needs to be installed and configured with your OCI credentials, including the user ' s OCID, tenancy OCID, region, and the path to the API signing key pair. By completing these steps, you can configure kubectl to access and manage your OKE clusters from your local machine using the OCI CLI authentication configuration.


                                    NEW QUESTION # 160
                                    Which open source engine is used by Oracle Cloud Infrastructure (OCI) to power Oracle Functions?

                                    Answer: C

                                    Explanation:
                                    Fn Project is the open source engine that is used by OCI to power Oracle Functions1. Fn Project is an open source, container native, serverless platform that can be run anywhere - any cloud or on-premises1. Fn Project is easy to use, extensible, and performant. You can download and install the open source distribution of Fn Project, develop and test a function locally, and then use the same tooling to deploy that function to Oracle Functions1.Verified References: Overview of Functions
