Oracle Cloud Infrastructure 2025 Developer Professional Sample Questions (Q20-Q25):

NEW QUESTION # 20
What is the open source engine for Oracle Functions?

A. Fn Project
B. Knative
C. OpenFaas
D. Apache OpenWhisk

Answer: A

Explanation:
The Fn Project is an open source serverless computing platform that serves as the engine for Oracle Functions. It provides a runtime environment for executing functions in a serverless architecture. The Fn Project enables developers to build and deploy functions using different programming languages, including Java, Python, Node.js, and more. The Fn Project is designed to be flexible and extensible, allowing developers to define functions as small units of code and execute them in response to events or triggers. It supports event-driven execution, allowing functions to be triggered by various events such as HTTP requests, messages from messaging systems, or changes in data. Oracle Functions leverages the Fn Project as its underlying engine, providing a managed serverless platform within the Oracle Cloud Infrastructure. It allows developers to easily develop, deploy, and manage functions using the familiar Fn Project framework and tooling. With Oracle Functions, developers can focus on writing their function code while leaving the infrastructure management, scaling, and operational tasks to the platform.

NEW QUESTION # 21
How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?

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

Answer: B

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 # 22
Which THREE are valid statements regarding the OCI Container Engine for Kubernetes (OKE) service? (Choose three.)

A. You must have access to an Oracle Cloud Infrastructure tenancy. Your tenancy must have sufficient quota on different types of resources.
B. OKE automatically creates and configures new network resources for the new cluster.
C. There is a limit of three clusters within each region, but there is no limit on the number of nodes and pods you can create within each cluster.
D. OKE cannot use existing network resources for the creation of a new cluster.

Answer: A,B,C

Explanation:
The valid statements regarding the OCI Container Engine for Kubernetes (OKE) service are: OKE automatically creates and configures new network resources for the new cluster. When creating a new OKE cluster, the service automatically provisions and configures the necessary network resources, such as VCNs, subnets, route tables, security lists, and load balancers, to support the cluster. Your tenancy must have sufficient quota on different types of resources. Before creating an OKE cluster, you need to ensure that your Oracle Cloud Infrastructure (OCI) tenancy has sufficient quota for the required resources, such as compute instances, block storage, networking resources, and load balancers. You must have access to an Oracle Cloud Infrastructure tenancy. To use the OKE service, you need to have access to an OCI tenancy. This means you must have a valid OCI account and the necessary permissions to create and manage resources within the tenancy. The following statements are not valid: OKE cannot use existing network resources for the creation of a new cluster. OKE creates new network resources specifically for the cluster, and it does not support using existing network resources. There is a limit of three clusters within each region, but there is no limit on the number of nodes and pods you can create within each cluster. This statement is incorrect. There is no specific limit on the number of clusters you can create within a region in OKE. However, there may be certain limits or quotas on resources that can impact the number of clusters you can create.

NEW QUESTION # 23
You are developing a distributed application and you need a call to a path to always return a specific JSON content deploy an OCI API Gateway with the below API deployment specification. What is the correct value for type? { "routes" : [{ "path" : "/hello", "methods" : ["Get"), "backend" : { "type" : " ---------------- ", "status" : 200, "headers" : [{ "name" : "Content-Type", "value" : "application/json" }] "body" : "{"myjson": "consistent response"}" }}]}

A. HTTP_BACKEND
B. JSON_BACKEND
C. CONSTANT_BACKEND
D. STOCK_RESPONSE_BACKEND

Answer: D

Explanation:
The correct value for the "type" field in the API deployment specification is "STOCK_RESPONSE_BACKEND". By setting the "type" to "STOCK_RESPONSE_BACKEND", you are indicating that the backend for the specified route should return a pre-defined response. This type of backend is commonly used when you want a specific response to be returned consistently, regardless of the actual backend service implementation. In this case, the API deployment specification is configured to have a single route with the path "/hello" and the method "GET". The backend section specifies the type as "STOCK_RESPONSE_BACKEND". Additionally, it defines the response status code as 200, sets the "Content-Type" header to "application/json", and provides the JSON content in the "body" field. Using this configuration, any request to the "/hello" path with the "GET" method will always receive a consistent JSON response with the content "{"myjson": "consistent response"}".

NEW QUESTION # 24
Your team has chosen to use master encryption key (MEK) within an Oracle Cloud Infrastructure (OCI) Vault for encrypting Kubernetes secrets associated with your microservice deployments in OCI Container Engine for Kubernetes (OKE) clusters so that you can easily manage key rotation. Which of the following is NOT valid about rotating keys in the OCI Vault service?

A. Each key version is tracked internally with separate unique OCIDS.
B. Both software and HSM-protected MEKS can be rotated.
C. Once rotated, older key versions can be used for encryption until they are deleted.
D. When you rotate an MEK, a new key version is automatically generated.

Answer: C

Explanation:
The correct answer is: "Once rotated, older key versions can be used for encryption until they are deleted." The statement that is NOT valid about rotating keys in the OCI Vault service is: "Once rotated, older key versions can be used for encryption until they are deleted." In the OCI Vault service, when you rotate a master encryption key (MEK), a new key version is automatically generated. However, once a key is rotated and a new version is created, the older key versions are no longer usable for encryption. The purpose of key rotation is to ensure that the encryption keys are regularly updated and that older keys are no longer used to protect sensitive data. This enhances security by minimizing the impact of potential key compromises. The other statements mentioned are valid: Both software and hardware security module (HSM)-protected MEKs can be rotated. This provides flexibility in choosing the type of MEK and ensures that key rotation can be performed regardless of the encryption method used. Each key version is tracked internally with separate unique OCIDs (Oracle Cloud Identifiers). This allows for easy management and tracking of different key versions within the OCI Vault service. In summary, the statement that is NOT valid is the one suggesting that older key versions can still be used for encryption until they are deleted. Key rotation is designed to ensure the use of the latest key version and to retire older key versions to enhance security.
