                                                        Oracle Cloud Infrastructure Developer Professional Sample Questions (Q172-Q177):

                                                        NEW QUESTION # 172
                                                        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: B

                                                        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 # 173
                                                        From a DevOps process standpoint, it is a good practice to keep changes to an application under version control. Which of the following allows changes to a Docker image to be stored in a version control system?

                                                        Answer: B

                                                        Explanation:
                                                        The option that allows changes to a Docker image to be stored in a version control system is: docker commit The docker commit command is used to create a new image from a container ' s changes. It takes a running container as input, captures the changes made to it, and creates a new image with those changes. This new image can then be tagged and pushed to a registry, or saved locally. By using docker commit, you can effectively capture the changes made to a container as a new image and store it in a version control system along with the Dockerfile and other project files. This allows for reproducibility and traceability of changes to the Docker image over time.


                                                        NEW QUESTION # 174
                                                        Which credential type is required to act as the password when authenticating the Docker CLI to Oracle Cloud Infrastructure Registry?

                                                        Answer: D

                                                        Explanation:
                                                        Oracle Container Registry requires an OCI Auth Token when Docker prompts for the password during docker login. Oracle explicitly documents that the user first generates an auth token under the OCI user profile, then supplies the tenancy namespace and username as the Docker username and the auth token as the password. A Console password is intended for interactive OCI Console authentication and is not the Docker Registry credential. API signing keys authenticate signed OCI API requests used by the CLI, SDKs, and related tools, while Customer Secret Keys are associated with Object Storage compatibility APIs. Consequently, the programmatic credential designed specifically to serve as the Docker Registry password is the OCI Auth Token.


                                                        NEW QUESTION # 175
                                                        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: C

                                                        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.


                                                        NEW QUESTION # 176
                                                        Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics via Oracle Cloud Infrastructure (OCI) Monitoring. Which TWO metrics are collected and made available by this feature?
                                                        (Choose two.)

                                                        Answer: B,E

                                                        Explanation:
                                                        The correct answers are: Amount of RAM used by a function: Oracle Functions collects and reports the amount of memory (RAM) used by a function during its execution. This metric helps in monitoring and optimizing the resource consumption of functions. Length of time a function runs: Oracle Functions captures and provides the duration of function executions. This metric allows you to track the performance and responsiveness of your functions and identify any potential bottlenecks or delays. These metrics provide valuable insights into the resource utilization and performance of your functions, enabling you to monitor and optimize their behavior in the Oracle Cloud Infrastructure (OCI) environment.
