Oracle Cloud Infrastructure 2024 Developer Professional Sample Questions (Q12-Q17):

NEW QUESTION # 12
You are building a cloud native serverless travel application with multiple Oracle Functions in Java, Python, and Node.js. You need to build and deploy these functions to a single application named travel-app. Which command will help you complete this task successfully?

  • A. fn function deploy app travel-app--all
  • B. fn app --app travel-app deploy --ext java pyljs
  • C. fn deploy--app travel-app --all
  • D. fn app deploy --app travel-app --all

Answer: C

Explanation:
The correct answer is: fn deploy --app travel-app --all Explanation: To build and deploy multiple Oracle Functions as part of a single application named "travel-app," you can use the fn deploy command with the appropriate options. The command fn deploy --app travel-app --all is the correct syntax. Here's what each part of the command does: fn deploy: This command is used to deploy functions and applications in Oracle Functions. --app travel-app: This option specifies the application name as "travel-app," indicating that you want to deploy functions to this application. --all: This option indicates that you want to deploy all the functions within the application. By using fn deploy --app travel-app --all, you can build and deploy all the functions in your travel application across different programming languages (Java, Python, and Node.js) to the "travel-app" application in Oracle Functions.


NEW QUESTION # 13
As a cloud-native developer, you are designing an application that depends on Oracle Cloud Infrastructure (OCI) Object Storage wherever the application is running. Therefore, provisioning of storage buckets should be part of your Kubernetes deployment process for the application. Which of the following should you leverage to meet this requirement? (Choose the best answer.)

  • A. OCI Service Broker for Kubernetes
  • B. Open Service Broker API
  • C. Oracle Functions
  • D. OCI Container Engine for Kubernetes

Answer: A

Explanation:
To provision storage buckets as part of your Kubernetes deployment process for an application that depends on Oracle Cloud Infrastructure (OCI) Object Storage, you should leverage the OCI Service Broker for Kubernetes. OCI Service Broker for Kubernetes enables you to provision and manage OCI resources, including Object Storage buckets, directly from Kubernetes. It provides a Kubernetes-native experience for managing OCI services, allowing you to define and manage OCI resources as part of your application deployment process. By using the OCI Service Broker for Kubernetes, you can define the required Object Storage buckets in your Kubernetes manifests, and the service broker will handle the provisioning and management of those buckets in OCI, ensuring that they are available for your application wherever it is running.


NEW QUESTION # 14
You deployed a Python application to an Oracle Container Engine for Kubernetes (OKE) cluster. However, while testing you found a bug, which you rectified and then created a new Docker image. You now need to ensure that if this new image does not work once deployed, you should be able to roll back to the previous version. Using kubect1, which strategy should you use?

  • A. A/B Testing
  • B. Canary Deployment
  • C. Blue/Green Deployment
  • D. Rolling Update

Answer: D

Explanation:
A rolling update is a deployment strategy that gradually replaces the old version of an application with the new version without any downtime4. OKE supports rolling updates by using the kubectl rollout command4. A rolling update allows you to roll back to the previous version if something goes wrong with the new version4.
Therefore, using a rolling update strategy with kubectl ensures that you can roll back to the previous version of your Python application if the new image does not work once deployed. Verified References: Deploy Oracle Container Engine for Kubernetes


NEW QUESTION # 15
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?

  • A. Custom CA or custom CA bundles can be added to your gateway's trust store ONLY if they already exist in the OCI Certificates service.
  • B. 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).
  • C. Once the mTLS request policy is enabled, ALL requests with valid certificates are routed to the backend unless you have defined one or more particular values (such as a domain name).
  • D. The mTLS request policy can only be enabled at the API deployment specification level, which then applies globally to ALL routes in that deployment.

Answer: B

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 # 16
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. Create a separate load balancer instance for each service using the lowest 100 Mbps option.
  • D. Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.

Answer: D

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.
