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

                                    NEW QUESTION # 116
                                    Your organization is developing serverless applications with Oracle Functions. Many functions will need to store state data in a database, which will require using appropriate credentials. However, your corporate security standards mandate encryption of secret information, such as database passwords. How would you address this security requirement?

                                    Answer: A

                                    Explanation:
                                    The best way to store and use secret information, such as database passwords, in Oracle Functions is to use the OCI Vault service. The OCI Vault service provides encryption and decryption capabilities for sensitive data. You can use the OCI Vault service to encrypt the password and store it as an application-level configuration variable. Then, you can use the generated key to decrypt the password in your function code when you need to access the database.

                                    NEW QUESTION # 117
                                    A DevOps engineer is troubleshooting the Meshifyd application, which is running in an Oracle Cloud Infrastructure (OCI) environment. The engineer has set up the OCI Logging service to store access logs for the application but notices that the logs from the Meshifyd application are not showing up in the logging service. The engineer suspects that there might be an issue with the logging configuration. Which two statements are potential reasons for logs from the Meshifyd application not showing up in the OCI Logging service?

                                    Answer: A,E

                                    Explanation:
                                    The logconfig.json file is a configuration file that specifies how the Unified Monitoring Agent collects and uploads custom logs to the OCI Logging service2. The logconfig.json file contains an array of objects, each representing a custom log configuration2. Each custom log configuration object has the following fields2:
                                    * logGroupObjectId: The OCID of the log group where the custom log is stored.
                                    * logObjectId: The OCID of the custom log.
                                    * paths: An array of paths to files or directories containing the custom logs.
                                    * src: A regular expression that matches the files containing the custom logs.
                                    * parser: A parser definition that specifies how to parse the custom logs. If the logconfig.json file has incorrect or missing OCID for the custom log in the logobjectId field, or incorrect or missing OCID for the custom log group in the logGroupObjectId field, then the Unified Monitoring Agent will not be able to upload the custom logs to the OCI Logging service2. Therefore, these are potential reasons for logs from the Meshifyd application not showing up in the OCI Logging service. Verified References: Unified Monitoring Agent Configuration File


                                    NEW QUESTION # 118
                                    How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?

                                    Answer: A

                                    Explanation:
                                    Blue/Green deployment strategy allows releasing a new version of an application using two identical environments where one of them is active at a given time. The current version of the application is provisioned on the active environment, whereas the new version gets deployed to the standby environment1. The traffic is shifted from the active to the standby environment by updating the ingress resource2. Therefore, both old and new application versions are deployed to production at the same time, but only one of them receives the traffic.

                                    NEW QUESTION # 119
                                    Which configuration parser type is mandatory when setting up a custom log with the OCI Unified Monitoring Agent if no log structure parsing is required?

                                    Answer: D

                                    Explanation:
                                    Oracle explicitly states that theNONEparser type is required when configuring the Unified Monitoring Agent even when no particular parsing of the incoming log structure is desired. The agent configuration still requires a parser declaration so it knows how the input should be handled. NONE allows the log content to be collected without applying structural parsing such as JSON, SYSLOG, regular-expression, or Apache-style parsing. Oracle ' s SDK model also lists NONE as a supported parserType value. RAW, DEFAULT, and UNSTRUCTURED are not the documented parser-type identifiers for this purpose. Consequently, administrators configuring custom logs that should be ingested without parsing must explicitly select or specify NONE, making C the correct answer.


                                    NEW QUESTION # 120
                                    Kubernetes includes various elements such as compute, network, and storage. Compute is essentially CPU (units) and memory (bytes). Within an OKE cluster, what is considered to be the smallest unit of deployment with respect to compute?

                                    Answer: C

                                    Explanation:
                                    A pod is the smallest and simplest unit in the Kubernetes object model that you create or deploy2. A pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When you create a pod, you define how much CPU and memory (RAM) each container needs. A pod can also include storage volumes, IP addresses, options that govern how the container(s) should run, and more2. Pods are the basic building blocks of larger Kubernetes constructs such as deployments, replica sets, and services2.
