                                                        NEW QUESTION # 31
                                                        Your company requires strict compartment isolation for an event-driven automation framework. You have deployed an Oracle Functions function inside a secure compartment named SecOps-Fn-Compartment. An OCI Events rule has been configured in a separate compartment named App-Resources-Compartment to capture critical resource state changes. Which configuration approach is required to allow the OCI Events service to successfully invoke your function?

                                                        Answer: A

                                                        Explanation:
                                                        OCI Events invokes configured action resources as a managed service rather than by assuming the identity of the human user who created the rule. Oracle ' s Events material documents the service principal cloudEvents and the policy pattern allowing that service to use functions-family. Scoping that permission to the compartment containing the target Function provides the required compartment isolation. A dynamic group is inappropriate because an Events rule is not a Compute instance or workload principal. Granting permissions to oraclefunctions reverses the invocation relationship, while granting a user group broad function- management rights does not authorize the Events runtime itself. Current Oracle documentation additionally represents cross-tenancy delivery using an eventrule principal and FN_INVOCATION; within the source scenario, B is the intended service authorization model.


                                                        NEW QUESTION # 32
                                                        You are writing a script to automate operational reports and need to extract custom aggregated CPU utilization metrics for a set of compute instances within your compartment. Which OCI CLI command should you run to retrieve this aggregated metric data from the OCI Monitoring service?

                                                        Answer: A

                                                        Explanation:
                                                        The correct command is oci monitoring metric-data summarize-metrics-data. Oracle defines this operation specifically for retrieving aggregated metric data that matches a Monitoring Query Language (MQL) expression. The command accepts parameters including the compartment OCID, metric namespace, and -- query-text, which can contain expressions such as CpuUtilization[1m].mean(). The post operation performs the opposite function: it publishes custom metric data into OCI Monitoring rather than retrieving it. query and retrieve are not valid subcommands under oci monitoring metric-data. Therefore, when an automation script must obtain aggregated CPU utilization or another metric series from Monitoring, summarize-metrics-data is the documented OCI CLI operation.


                                                        NEW QUESTION # 33
                                                        As a developer, you have been tasked with implementing a microservices-based application. Which THREE technologies are best suited to accomplish the task? (Choose three.)

                                                        Answer: B,C,E

                                                        Explanation:
                                                        The three technologies best suited for implementing a microservices-based application are: Service Mesh: A service mesh is a dedicated infrastructure layer that provides features like service discovery, load balancing, encryption, authentication, and observability for microservices. It helps in managing the communication and interactions between microservices in a scalable and secure manner. Kubernetes: Kubernetes is an open- source container orchestration platform that enables the deployment, scaling, and management of containerized applications. It provides features like automated scaling, service discovery, load balancing, and self-healing capabilities, which are essential for managing microservices in a distributed environment.
                                                        Docker: Docker is a popular containerization platform that allows packaging applications and their dependencies into lightweight containers. It provides a consistent and portable environment for running microservices, enabling easy deployment and scalability. Docker also facilitates isolation and resource efficiency, making it an ideal choice for deploying microservices. While Big Data, Anomaly Detection, and Terraform are valuable technologies, they are not specifically focused on enabling the implementation of microservices-based applications.


                                                        NEW QUESTION # 34
                                                        You are setting up OCI Application Performance Monitoring (APM) to trace transactions in a Spring Boot application. Which installer command should you execute to provision the APM Java Agent with its target application service name, destination directory, and credentials obtained from your APM domain?

                                                        Answer: C

                                                        Explanation:
                                                        Oracle APM documentation specifies the provision-agent operation for installing and configuring the APM Java Agent. Its mandatory arguments include -service-name, identifying the monitored service; -destination, specifying where the agent is provisioned; -private-data-key, using the installation key generated for the APM domain; and -data-upload-endpoint, identifying the domain ' s upload endpoint. Oracle provides essentially the same command structure as option D in its provisioning documentation. register-agent, install-agent, and configure-agent are not the documented provisioning subcommands, while the alternative parameter names such as -app-name, -upload-key, and -path do not match Oracle ' s mandatory syntax. Consequently, option D is the fully documented command.


                                                        NEW QUESTION # 35
                                                        What can you use to dynamically make Kubernetes resources discoverable to public DNS servers? (Choose the best answer.)

                                                        Answer: D

                                                        Explanation:
                                                        To dynamically make Kubernetes resources discoverable to public DNS servers, you can use ExternalDNS.
                                                        ExternalDNS is a Kubernetes add-on that automates the management of DNS records for your Kubernetes services and ingresses. It can be configured to monitor the changes in your Kubernetes resources and automatically update DNS records in a supported DNS provider. By integrating ExternalDNS with your Kubernetes cluster, you can ensure that the DNS records for your services and ingresses are automatically created, updated, or deleted based on changes in your Kubernetes resources. This allows your Kubernetes resources to be discoverable by external systems through public DNS servers.
