                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q85-Q90):

                                    NEW QUESTION # 85
                                    Which is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service?

                                    Answer: A

                                    Explanation:
                                    The use case that is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service is " Capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances. " The OCI Events service is designed to provide event-driven architecture and enable automated responses to events occurring within the Oracle Cloud Infrastructure. It allows you to react to changes and activities happening within your OCI resources. The Events service can be used to trigger actions based on events like file uploads, resource changes, or task completions. However, capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances is not a direct functionality provided by the OCI Events service. Autoscaling based on monitoring metrics is typically handled by the OCI Autoscaling service, which is specifically designed for that purpose. The OCI Monitoring service provides monitoring and alerting capabilities, while the Autoscaling service handles the dynamic scaling of compute instances based on predefined policies and thresholds.


                                    NEW QUESTION # 86
                                    Which component of the Docker architecture is the persistent background service responsible for managing container lifecycles, local images, networks, and storage volumes?

                                    Answer: B

                                    Explanation:
                                    The Docker daemon, implemented as the dockerd background process, runs continuously on a Docker host and performs the server-side container-management operations requested through the Docker API. It manages container execution, images, storage drivers and volumes, and networking. The Docker client is the command interface that sends requests to that daemon; it does not itself manage container lifecycles. A Docker registry such as OCIR stores and distributes images remotely, while Docker Compose describes and coordinates multi- container application configurations. Oracle ' s Linux container documentation explicitly refers to the Docker Engine daemon and its dockerd process, and Oracle Functions troubleshooting likewise distinguishes the local Docker client/daemon from the remote registry. Therefore, the persistent management component described in the question is the Docker Daemon.


                                    NEW QUESTION # 87
                                    You are configuring an Oracle Cloud Infrastructure Events rule to process lifecycle changes for both Object Storage objects and Compute instances within a single compartment. Which JSON filter attribute structure correctly groups multiple event types under a single filter condition?

                                    Answer: A

                                    Explanation:
                                    Oracle Events uses the singular top-level field eventType to identify the type of event represented by an event message. When a rule must match more than one event type, Oracle explicitly documents placing multiple event-type strings in a JSON array assigned to eventType. Values within that array operate as alternatives, allowing the condition to match an event corresponding to any listed type. eventTypes, actionTypes, and filterType are not valid substitutes for the documented field. Likewise, concatenating event types into a single pipe-delimited or comma-delimited string does not create multiple event matches. Option D therefore implements the exact structure Oracle shows in its Events filtering examples for a rule covering multiple event types.


                                    NEW QUESTION # 88
                                    Which " Action Type " option is NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition?

                                    Answer: C

                                    Explanation:
                                    An action is a response that you define for the rule to perform when the filter finds a matching event1. The action type specifies the service that you want to invoke by delivering the event message1. The following action types are available in OCI Events rule definition1:
                                    * Streaming: Send to a stream from Oracle Streaming Service.
                                    * Notifications: Send to an Oracle Notification Service topic.
                                    * Functions: Send to an Oracle Functions Service endpoint. Email is not a valid action type for OCI Events rule definition. To send an email as an action, you need to use the Notifications service and subscribe to a topic with an email protocol2.


                                    NEW QUESTION # 89
                                    Your Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) administrator has created an OKE cluster with one node pool in a public subnet. You have been asked to provide a log file from one of the nodes for troubleshooting purpose. Which step should you take to obtain the log file?

                                    Answer: D

                                    Explanation:
                                    To obtain a log file from one of the nodes in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster, you should SSH into the nodes using the private key. Here ' s the step-by-step process: Obtain the private key: The private key is required to authenticate and access the nodes in the OKE cluster. You should obtain the private key from your administrator or the appropriate key pair used to create the cluster. SSH into the node: Use a secure shell (SSH) client, such as OpenSSH, to connect to the desired node in the cluster. The SSH command typically includes the private key file path and the public IP address or hostname of the node. Example command: ssh -i < private_key_file > opc@ < node_public_ip > Replace < private_key_file > with the path to the private key file and < node_public_ip > with the public IP address of the node you want to access. Navigate to the log file location: Once you have successfully connected to the node, navigate to the directory where the log file is located. The exact location and name of the log file may vary depending on the Kubernetes distribution and configuration. Copy or view the log file: You can either copy the log file from the node to your local machine using the scp command or view the contents directly on the node using tools like cat or less. By following these steps, you will be able to access the log file from the desired node in the OKE cluster for troubleshooting purposes.
