Oracle Cloud Infrastructure 2025 Developer Professional Sample Questions (Q33-Q38):

NEW QUESTION # 33
You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. It has multiple endpoints that need to be exposed to the public internet. What is the most cost-effective way to expose multiple application endpoints without adding unnecessary complexity to the application?

  • A. Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.
  • B. Use a ClusterIP service type in Kubernetes for each of your service endpoints using a load balancer to expose the endpoints.
  • C. Create a separate load balancer instance for each service using the lowest 100 Mbps option.
  • D. Use a NodePort service type in Kubernetes for each of your service endpoints using the node's public IP address to access the applications.

Answer: A

Explanation:
An Ingress Controller is a Kubernetes resource that provides advanced routing and load balancing for your applications running on a Kubernetes cluster1. An Ingress Controller allows you to define rules that specify how to route traffic to different services in your cluster based on the host name or path of the incoming request1. By deploying an Ingress Controller and using it to expose multiple application endpoints, you can achieve the following benefits1:
Cost-effectiveness: You only need to create one load balancer instance per cluster, instead of one per service, which reduces the cost of exposing your applications.
Simplicity: You only need to manage one set of routing rules for all your services, instead of configuring each service separately, which simplifies the application deployment and maintenance.
Flexibility: You can use different types of Ingress Controllers, such as NGINX or Traefik, that offer various features and customization options for your routing needs.


NEW QUESTION # 34
What are the TWO main reasons you would choose to implement a serverless architecture? (Choose two.)

  • A. Automatic horizontal scaling
  • B. Improved in-function state management
  • C. Reduced operational cost
  • D. No need for integration testing
  • E. Easier to run long-running operations

Answer: A,C

Explanation:
The two main reasons to choose a serverless architecture are: Automatic horizontal scaling: Serverless architectures allow for automatic scaling of resources based on demand. The infrastructure automatically provisions and scales resources as needed, ensuring that applications can handle varying workloads efficiently. This eliminates the need for manual scaling and optimizes resource utilization. Reduced operational cost: Serverless architectures follow a pay-per-use model, where you are billed only for the actual execution time and resources consumed by your functions. This leads to cost savings as you don't have to pay for idle resources. Additionally, serverless architectures remove the need for managing and maintaining servers, reducing operational overhead and associated costs. Explanation:: No need for integration testing: Integration testing is still necessary in serverless architectures to ensure that functions integrate correctly with other components and services. Serverless functions can interact with various event sources, databases, and APIs, and testing is required to verify the integration points. Improved in-function state management: Serverless architectures typically encourage stateless functions that operate on short-lived requests or events. While there are mechanisms to manage state within a function, serverless architectures are designed to be stateless by default, promoting scalability and fault tolerance. Easier to run long-running operations: Serverless functions are generally designed for short-lived operations rather than long-running tasks. If you have a requirement for long-running operations, a serverless architecture may not be the ideal choice, as it has execution time limits and may not provide the necessary resources for extended execution.


NEW QUESTION # 35
How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?

  • A. Both old and new application versions are deployed to production at the same time.
  • B. New application versions are deployed in minor increments to a select group of people.
  • C. Current applications are slowly replaced with new application versions.

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 # 36
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?

  • A. Encrypt the password using the OCI Vault service and then decrypt this password in your function code with the generated key.
  • B. Leverage application-level configuration variables to store passwords because they are automatically encrypted by Oracle Functions.
  • C. Use the OCI Vault service to auto-encrypt the password and then set an application-level configuration variable to reference the auto-decrypted password inside your function container.
  • D. Use OCI Console to enter the password in the function configuration section in the provided input field.

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 # 37
(CHK_1>3) You have an e-commerce application that loads customers' transactional data into the Oracle Cloud Infrastructure (OCI) Streaming service. The data must now be extracted and transformed before sending it to a third-party REST endpoint. You have been directed to leverage the OCI Service Connector Hub to automate this process. Which configuration option would address this requirement?

  • A. Configure a new service connector as follows: * Source: Streaming * Task: Functions * Target: API Gateway
  • B. Configure a new service connector as follows: * Source: Streaming * Task: API Gateway * Target: Notifications
  • C. Configure a new service connector as follows: * Source: Streaming * Task: API Gateway * Target: Functions
  • D. Configure a new service connector as follows: * Source: Streaming * Task: None * Target: Notifications
  • E. Configure a new service connector as follows: * Source: Streaming * Task: Functions * Target: Functions

Answer: D

Explanation:
To address the requirement of extracting and transforming data from the Oracle Cloud Infrastructure (OCI) Streaming service and sending it to a third-party REST endpoint using the OCI Service Connector Hub, the best configuration option is: Configure a new service connector as follows: * Source: Streaming * Task: None * Target: Notifications By selecting the Streaming service as the source, you can capture the transactional data from the stream. Since there is a need to transform and send the data to a third-party REST endpoint, you don't need to specify any specific task in the connector. The target is set to Notifications, which allows you to send the transformed data to an endpoint outside of the OCI environment. Notifications can be configured to deliver the data to various supported destinations, including HTTP endpoints, email addresses, and more. This configuration enables you to automate the process of extracting data from the streaming service and sending it to the desired third-party REST endpoint, fulfilling the requirement of extracting, transforming, and forwarding the data.
