Oracle Cloud Infrastructure 2025 Developer Professional Sample Questions (Q64-Q69):

NEW QUESTION # 64
Which is ONE of the differences between a microservice and a serverless function?

  • A. Microservices are stateless while serverless functions are stateful.
  • B. Microservices are triggered by events while serverless functions are not.
  • C. Microservices always use a data store while serverless functions never use a data store.
  • D. Microservices are used for long running operations while serverless functions are used for short running operations.

Answer: D

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 # 65
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. Use a NodePort service type in Kubernetes for each of your service endpoints using the node's public IP address to access the applications.
  • B. Use a ClusterIP service type in Kubernetes for each of your service endpoints using a load balancer to expose the endpoints.
  • C. Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.
  • D. Create a separate load balancer instance for each service using the lowest 100 Mbps option.

Answer: C

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 # 66
You are using Oracle Cloud Infrastructure (OCI) Resource Manager to manage your infrastructure lifecycle and wish to receive an email each time a Terraform action begins. How should you use the OCI Events service to do this without writing any code?

  • A. Create an OCI Email Delivery configuration with the destination email address. Then create an OCI Events rule matching "Resource Manager Job - Create" condition, and select the email configuration for the corresponding action.
  • B. Create an OCI Notifications topic and email subscription with the destination email address. Then create an OCI Events rule matching "Resource Manager Stack - Update" condition, and select the notification topic for the corresponding action.
  • C. Create an OCI Notification topic and email subscription with the destination email address. Then create an OCI Events rule matching "Resource Manager Job - Create" condition, and select the notification topic for the corresponding action.
  • D. Create a rule in OCI Events service matching the "Resource Manager Stack - Update" condition. Then select "Action Type: Email" and provide the destination email address.

Answer: C

Explanation:
The correct approach to receive an email each time a Terraform action begins in Oracle Cloud Infrastructure (OCI) Resource Manager without writing any code is as follows: Create an OCI Notification topic and email subscription with the destination email address. This will define the email delivery configuration. Create an OCI Events rule that matches the "Resource Manager Job - Create" condition. This rule will be triggered when a Resource Manager job is created. In the OCI Events rule, select the notification topic that was created in step 1 as the action for the corresponding event. This will ensure that the notification is sent to the specified email address. By following these steps, you can configure the OCI Events service to send an email notification whenever a Resource Manager job is created in OCI Resource Manager.


NEW QUESTION # 67
You have created a repository in Oracle Cloud Infrastructure Registry (OCIR) in the us-ashburn-1 (iad) region in your tenancy with the heyoci namespace. Which three are valid tags for an image named myapp? (Choose three.)

  • A. iad.ocir.io/heyoci/myproject/myapp:0.0.1
  • B. us-ashburn-1.ocir.io/heyoci/myproject/myapp:0.0.2-beta
  • C. iad.ocir.io/heyoci/myapp:0.0.2-beta
  • D. us-ashburn-1.ocir.io/heyoci/myapp:0.0.2-beta
  • E. iad.ccir.io/heyoci/myapp:latest
  • F. us-ashburn-1.ocir.io/myproject/heyoci/myapp:latest

Answer: A,B,E

Explanation:
(OPT) iad.ocir.io/myproject/heyoci/myapp:latest The three valid tags for an image named myapp in the heyoci namespace of the Oracle Cloud Infrastructure Registry (OCIR) in the us-ashburn-1 (iad) region are: iad.ccir.io/heyoci/myapp:latest This tag specifies the latest version of the myapp image in the heyoci namespace in the iad region. iad.ocir.io/heyoci/myapp:0.0.2-beta This tag specifies version 0.0.2-beta of the myapp image in the heyoci namespace in the iad region. us-ashburn-1.ocir.io/heyoci/myapp:0.0.2-beta This tag specifies version 0.0.2-beta of the myapp image in the heyoci namespace in the us-ashburn-1 region. The other options mentioned are not valid tags for the given scenario: us-ashburn-1.ocir.io/heyoci/myapp:0.0.2-beta (incorrect format, missing the namespace) iad.ocir.io/myproject/heyoci/myapp:latest (incorrect format, incorrect order of namespace and project) us-ashburn-1.ocir.io/myproject/heyoci/myapp:latest (incorrect format, incorrect order of namespace and project) The correct format for tagging an image in OCIR is <region>.ocir.io/<namespace>/<repository>:<tag>.


NEW QUESTION # 68
In the shared responsibility model, who should perform patching, upgrading, and maintaining of the worker nodes in provisioned Oracle Container Engine for Kubernetes (OKE) clusters?

  • A. It is the responsibility of the customer.
  • B. Oracle Support does it.
  • C. It is an automated process.

Answer: A

Explanation:
In the shared responsibility model, Oracle is responsible for securing the underlying cloud infrastructure and platform services, while customers are responsible for securing their data and applications within the cloud4. For provisioned OKE clusters, Oracle manages the control plane (master nodes) of the Kubernetes cluster, while customers manage the data plane (worker nodes) of the cluster5. Therefore, it is the responsibility of the customer to perform patching, upgrading, and maintaining of the worker nodes in provisioned OKE clusters5. Customers can use tools such as Terraform or kubectl to automate these tasks5.
