                                    Oracle Cloud Infrastructure Developer Professional Sample Questions (Q88-Q93):

                                    NEW QUESTION # 88
                                    Your development team has deployed a fleet of web application servers across three fault domains in a specific compartment in OCI. To simplify operational dashboards, you must construct a single Monitoring Query Language (MQL) expression that calculates the average CPU utilization for each individual fault domain, rather than plotting each server individually. The expression must output exactly three lines, one for each fault domain, on the resulting Metrics Explorer chart.
                                    Which MQL expression correctly fulfills these requirements?

                                    Answer: B

                                    Explanation:
                                    Oracle Monitoring documents groupBy(x) specifically for aggregating metric streams according to a shared dimension. Oracle ' s own fault-domain example uses the exact expression CpuUtilization[1m].groupBy (faultDomain).mean(). The resulting chart contains one aggregated metric stream for each fault domain, which means a compartment containing three fault domains produces three lines rather than one line per Compute instance. grouping() combines all selected metric streams into a single aggregate instead of retaining separate fault-domain groups. filter(faultDomain) is not the appropriate MQL grouping operation, and split() is not the documented operator for this requirement. Because the scenario requires mean CPU utilization separately aggregated for each value of the faultDomain dimension, option B exactly matches Oracle ' s documented MQL pattern.


                                    NEW QUESTION # 89
                                    Which TWO are part of the Cloud Native Computing Foundation (CNCF) container runtime? (Choose two.)

                                    Answer: A,C

                                    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 # 90
                                    You are configuring a deployment script running in an OCI Compute Instance that needs to retrieve database credentials stored in OCI Vault. Which OCI CLI command should your script execute to retrieve the secret bundle containing the credentials?

                                    Answer: A

                                    Explanation:
                                    Oracle separates secret-management operations from retrieval of secret contents. The current OCI CLI command for retrieving a secret bundle is oci secrets secret-bundle get --secret-id < secret_id > . If no specific version, stage, or version name is supplied, Oracle returns the bundle associated with the secret version marked CURRENT. The secrets data-plane command retrieves the actual secret bundle, including its encoded content and version properties. The alternative command paths shown in A, C, and D do not represent the documented OCI CLI operation for obtaining secret contents. Oracle ' s current Secrets Management documentation provides the same command directly when describing how applications and administrators retrieve a secret ' s contents. Therefore, option B is the exact verified command.


                                    NEW QUESTION # 91
                                    You are a developing a microservices application that will be a consumer of the Oracle Cloud Infrastructure (OCI) Streaming service. Which API method should you use to read and process a stream?

                                    Answer: E

                                    Explanation:
                                    The correct API method to read and process a stream in the Oracle Cloud Infrastructure (OCI) Streaming service is " GetMessages " . When consuming messages from a stream in OCI Streaming, you use the " GetMessages " API method. This method allows you to retrieve a batch of messages from the stream for processing. You can specify parameters such as the number of messages to retrieve, the maximum size of the messages, and the timeout for the request. By using the " GetMessages " API method, you can retrieve messages from the stream and then process them in your microservices application. This allows you to consume and handle the data in real-time as it becomes available in the stream. The " GetMessages " method provides flexibility in how you consume and process the messages, enabling you to implement custom logic and workflows based on your specific application requirements.


                                    NEW QUESTION # 92
                                    Which " Action Type " option is NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition?

                                    Answer: B

                                    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.
