NEW QUESTION # 81
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: B
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.

To enforce mutual TLS (mTLS) authentication for clients of your microservices, your team has chosen to leverage the Oracle Cloud Infrastructure (OCI) API Gateway service to create new API Deployments that will direct requests to your microservices. Which is NOT valid regarding the mTLS options in OCI API Gateway?
Answer: C
Explanation:
The correct answer is: " Adding a custom certificate authority (CA) or custom CA bundle to your gateway ' s trust store for mTLS is optional unless you need to reject certificates that do not contain particular values (such as a domain name). " The statement that is NOT valid regarding the mTLS options in OCI API Gateway is: " Adding a custom certificate authority (CA) or custom CA bundle to your gateway ' s trust store for mTLS is optional unless you need to reject certificates that do not contain particular values (such as a domain name).
" In OCI API Gateway, adding a custom certificate authority (CA) or custom CA bundle to the gateway ' s trust store is not optional. It is a necessary step when configuring mTLS authentication. The trust store in the gateway is used to validate the client certificates presented during mTLS authentication. The other options listed are valid regarding the mTLS options in OCI API Gateway: Once the mTLS request policy is enabled, all requests with valid certificates are routed to the backend unless specific values (such as a domain name) are defined. This means that only requests with valid client certificates will be allowed to access the backend microservices. The mTLS request policy can only be enabled at the API deployment specification level, and it applies globally to all routes in that deployment. This ensures consistent mTLS authentication across all routes and endpoints in the API deployment. Custom CA or custom CA bundles can be added to the gateway ' s trust store, but only if they already exist in the OCI Certificates service. This allows you to include trusted CAs or CA bundles to validate client certificates during mTLS authentication.
NEW QUESTION # 83
Which is ONE of the differences between a microservice and a serverless function?
Answer: C
Explanation:
The correct answer is: Microservices are used for long running operations while serverless functions are used for short running operations. One of the key differences between microservices and serverless functions is the duration of their execution. Microservices are typically designed to handle long-running operations and may continuously run and process requests as part of a larger system. They are often deployed and managed as long-lived services. On the other hand, serverless functions are designed to handle short-lived operations or tasks that execute in response to specific events or triggers. They are event-driven and execute only when invoked, providing a lightweight and ephemeral computing model. Serverless functions are often used for executing small, isolated pieces of code without the need for managing infrastructure or scaling concerns.
While both microservices and serverless functions can be stateless or stateful depending on the specific implementation, the key distinction lies in the typical duration and execution pattern of these components within an application architecture.
NEW QUESTION # 84
Which key pillar of cloud native development should be utilized when a development team needs to automate build, test, and release cycles to achieve rapid and reliable software delivery?
Answer: B
Explanation:
DevOps principles directly address automation across the software delivery lifecycle. Oracle describes DevOps as collaboration between development and operations teams aimed at continuous delivery, with automation applied throughout planning, coding, building, testing, releasing, deploying, operating, and monitoring. OCI specifically identifies CI/CD tooling for automating build, test, release, and deployment activities. Containerization provides consistent application packaging, microservices define an architectural decomposition model, and serverless computing removes much of the underlying infrastructure-management responsibility. None of those technologies by itself defines the automated delivery lifecycle requested in the question. Continuous Integration and Continuous Delivery are core DevOps practices that make software changes repeatable, testable, and deployable at high frequency while reducing manual intervention and release risk. Therefore, the correct cloud-native pillar is DevOps Principles.
NEW QUESTION # 85
Which of the following is NOT a criterion that is usually met by a microservice?
Answer: A
Explanation:
The correct answer is: " Tightly coupled. " Tightly coupling is not a criterion that is usually met by a microservice. In fact, microservices are designed to be loosely coupled. Loosely coupling refers to reducing dependencies and minimizing the direct interactions between different components or services. Microservices promote independence and autonomy, allowing each service to operate independently without being tightly bound to other services. The other options listed are criteria that are typically met by microservices:
Organized around business capabilities: Microservices architecture suggests designing services around specific business capabilities or functionalities. This allows for focused and specialized services that align with the organization ' s business needs. Independently deployable: Microservices are designed to be independently deployable units. Each microservice can be developed, tested, and deployed separately, without impacting other services. This enables agility and scalability in the deployment process. Highly maintainable:
Microservices are often designed to be highly maintainable. They are smaller in scope and focused on specific tasks, making it easier to manage and maintain individual services. Additionally, microservices can be updated, patched, or replaced without affecting the entire system, facilitating easier maintenance and evolution of the application. Therefore, the criterion that is NOT typically met by a microservice is being tightly coupled.
