                                                        Oracle Cloud Infrastructure Developer Professional Sample Questions (Q116-Q121):

                                                        NEW QUESTION # 116
                                                        Which special column in the OCI Logging Query Language represents the raw text of the entire original log message?

                                                        Answer: B

                                                        Explanation:
                                                        Oracle ' s Logging Query Language specification defines logContent as aspecial column representing the text of the whole original message. This field is particularly valuable when the required information is not available through a known indexed JSON field or when administrators need full-text matching across the original log payload. For example, Oracle documents queries such as where logContent = ' *ERROR* ' to return log lines containing the specified text. messageBody, rawPayload, and eventSource are not documented LQL special columns representing the complete original message. Individual services can contain fields such as data.message, but those fields are part of the service-specific structured payload rather than the universal raw-message special column. Therefore, A is correct.


                                                        NEW QUESTION # 117
                                                        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: A,C,D

                                                        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 # 118
                                                        Which statement accurately describes the Oracle Cloud Infrastructure (OCI) Load Balancer integration with OCI Container Engine for Kubernetes (OKE)?

                                                        Answer: D

                                                        Explanation:
                                                        The statement that accurately describes the Oracle Cloud Infrastructure (OCI) Load Balancer integration with OCI Container Engine for Kubernetes (OKE) is: " OKE service provisions an OCI Load Balancer instance for each Kubernetes service with LoadBalancer type in the YAML configuration. " When you define a Kubernetes service in your YAML configuration with the LoadBalancer type, the OKE service automatically provisions an OCI Load Balancer instance specifically for that service. This Load Balancer instance is dedicated to the Kubernetes service and provides traffic balancing functionality. Each Kubernetes service that requires load balancing will have its own OCI Load Balancer instance provisioned by OKE.


                                                        NEW QUESTION # 119
                                                        Which statement is NOT valid regarding OCI Identity and Access Management (IAM) policies written for OKE Workload Identity?

                                                        Answer: D

                                                        Explanation:
                                                        Oracle ' s documented OKE Workload Identity policy pattern is Allow any-user to < verb > < resource > in < location > where all {...} with conditions identifying request.principal.type= ' workload ' , the Kubernetes namespace, service account, and cluster OCID. Crucially, Oracle defines < location > as either the entire tenancyor a specific compartment. Oracle even provides examples granting a workload access only to resources in a named compartment. Consequently, C is false because workload-identity policies do not have to be tenancy-wide. Options A, B, and D accurately describe the standard policy structure: any-user is narrowed through workload-specific conditions, and those conditions identify the exact OKE workload by cluster, namespace, and service account. This enables fine-grained least-privilege access without storing OCI credentials inside pods.


                                                        NEW QUESTION # 120
                                                        Your development team wants to configure API Gateway request validation to shield an upstream backend microservice from ill-formed API calls. You want to test the validation rules in your staging environment first without blocking any non-compliant client requests, and you want to ensure the gateway checks that a mandatory HTTP header is present. Which TWO configurations should you apply to your API Gateway deployment specification to meet this requirement?

                                                        Answer: A,D

                                                        Explanation:
                                                        OCI API Gateway request validation supportsEnforcing, Permissive, and Disabledvalidation modes. In Permissive mode, requests are validated and failures are recorded, but even non-compliant requests continue to the backend, making it appropriate for testing the impact of validation before enforcing it. Oracle also supports explicit header validation rules in which a header can be marked required: true. Enforcing mode instead blocks requests that fail validation and returns a 4xx response. No dynamic group is required for API Gateway to validate standard HTTP headers, and request.auth relates to authentication context rather than header-presence validation. Therefore, A and C directly satisfy both stated requirements.
