                                                        Oracle Cloud Infrastructure Developer Professional Sample Questions (Q52-Q57):

                                                        NEW QUESTION # 52
                                                        You have developed a cloud-native application on OCI, and you need to enable diagnostic logging for an OCI API Gateway deployment and a backend Oracle Function. Corporate compliance mandates that both the gateway activity and the function execution logs must be collected and stored in separate centralized log resources under a common log group named AppLoggingGroup.
                                                        Which TWO configuration steps must you perform within the OCI Logging service to satisfy these requirements?

                                                        Answer: C,E

                                                        Explanation:
                                                        API Gateway and Oracle Functions are OCI-managed services with native integration into OCI Logging, so their diagnostic output is collected throughservice logs, not host-based custom-log agent configurations.
                                                        Oracle ' s Service Log Reference explicitly includes both API Gateway and Functions. For Functions, Oracle ' s current CLI example creates a SERVICE log whose source resource is the Function application and whose category is invoke. API Gateway likewise exposes service logging for gateway/deployment activity. Both log resources can be placed in the same organizational log group while remaining separate log objects, satisfying the compliance requirement. Logging agents and custom logs are intended primarily for files produced on managed hosts or applications, not for these managed OCI service sources. Therefore, C and D are correct.


                                                        NEW QUESTION # 53
                                                        You have built a local container image named order-processor:1.0 and need to push it to a repository named order-services in your Phoenix region (phx) tenancy, which has the Object Storage namespace ax39m19vpw.
                                                        Which command must you run to properly tag the local image before pushing it to Container Registry?

                                                        Answer: B

                                                        Explanation:
                                                        OCI Container Registry requires the destination image tag to use the structure < region-key > .ocir.io/ < tenancy-namespace > / < repository-name > : < tag > . For Phoenix, the region key is phx; the supplied tenancy namespace is ax39m19vpw; the repository is order-services; and the image tag is 1.0. Combining these values produces phx.ocir.io/ax39m19vpw/order-services:1.0. Oracle ' s current container documentation provides the same docker tag structure before an image is pushed to OCIR. The alternative commands incorrectly reorder the namespace and registry host or use an unsupported registry hostname format.
                                                        Therefore, option A correctly retags the local order-processor:1.0 image with the fully qualified OCIR repository path required for the subsequent docker push.


                                                        NEW QUESTION # 54
                                                        You are building a container image and pushing it to Oracle Cloud Infrastructure Registry (OCIR). You need to ensure that these images never get deleted from the repository. Which action should you take?

                                                        Answer: C

                                                        Explanation:
                                                        To prevent images from being deleted from a repository, you can set the global policy of image retention to
                                                        "Retain All Images". This policy applies to all repositories in the tenancy and overrides any individual repository settings. You can also lock the policy to prevent any changes to it.Verified References: Using Retention Rules to Preserve Data


                                                        NEW QUESTION # 55
                                                        Your team has chosen to use master encryption key (MEK) within an Oracle Cloud Infrastructure (OCI) Vault for encrypting Kubernetes secrets associated with your microservice deployments in OCI Container Engine for Kubernetes (OKE) clusters so that you can easily manage key rotation. Which of the following is NOT valid about rotating keys in the OCI Vault service?

                                                        Answer: A

                                                        Explanation:
                                                        The correct answer is: " Once rotated, older key versions can be used for encryption until they are deleted. " The statement that is NOT valid about rotating keys in the OCI Vault service is: " Once rotated, older key versions can be used for encryption until they are deleted. " In the OCI Vault service, when you rotate a master encryption key (MEK), a new key version is automatically generated. However, once a key is rotated and a new version is created, the older key versions are no longer usable for encryption. The purpose of key rotation is to ensure that the encryption keys are regularly updated and that older keys are no longer used to protect sensitive data. This enhances security by minimizing the impact of potential key compromises. The other statements mentioned are valid: Both software and hardware security module (HSM)-protected MEKs can be rotated. This provides flexibility in choosing the type of MEK and ensures that key rotation can be performed regardless of the encryption method used. Each key version is tracked internally with separate unique OCIDs (Oracle Cloud Identifiers). This allows for easy management and tracking of different key versions within the OCI Vault service. In summary, the statement that is NOT valid is the one suggesting that older key versions can still be used for encryption until they are deleted. Key rotation is designed to ensure the use of the latest key version and to retire older key versions to enhance security.


                                                        NEW QUESTION # 56
                                                        You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. Your security team wants to use SSL termination for this application.
                                                        What should you do to create a secure SSL termination for this application using the fewest steps possible?

                                                        Answer: B

                                                        Explanation:
                                                        The correct answer is: " Create a self-signed certificate and its corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these annotations to the Kubernetes service: annotations: service.
                                                        beta.kubernetes.io/oci-load-balancer-ssl-ports: ' 443 ' service.beta.kubernetes.io/oci-load-balancer-tls-secret:
                                                        ssl certificate-secret. " To create a secure SSL termination for your microservices-based application running in an OCI Container Engine for Kubernetes (OKE) cluster, you can follow these steps: Create a self-signed certificate and its corresponding key: Generate a self-signed SSL certificate and its private key using a tool like OpenSSL. Create a Kubernetes secret: Create a Kubernetes secret using the certificate and key obtained in the previous step. This secret will securely store the certificate and key within the Kubernetes cluster. Add annotations to the Kubernetes service: Modify the Kubernetes service that exposes your application and add the following annotations to enable SSL termination: annotations: service.beta.kubernetes.io/oci-load- balancer-ssl-ports: ' 443 ' (specify the SSL port as 443) annotations: service.beta.kubernetes.io/oci-load- balancer-tls-secret: ssl certificate-secret (specify the name of the Kubernetes secret containing the certificate and key) By following these steps, you can create a secure SSL termination for your application using a self- signed certificate and Kubernetes secret. The annotations added to the Kubernetes service ensure that the SSL port is configured correctly and the TLS secret is utilized for SSL termination when traffic reaches the load balancer. The other options provided are not the most suitable approaches for achieving secure SSL termination in an OCI Container Engine for Kubernetes (OKE) cluster: Adding annotations related to the OCI load balancer SSL secret key is not the correct approach for SSL termination in this scenario. Using Let ' s Encrypt to generate a self-signed certificate and configuring it on the OCI Load Balancer is not necessary when you can create and manage the SSL certificate within the Kubernetes cluster using a Kubernetes secret.
