Oracle Cloud Infrastructure 2025 Developer Professional Sample Questions (Q66-Q71):

NEW QUESTION # 66
What is the open source engine for Oracle Functions?

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

Answer: D

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 # 67
What is the difference between blue/green and canary deployment strategies? (Choose the best answer.)

A. In blue/green, current applications are slowly replaced with new ones. In canary, the application Is deployed Incrementally to a select group of people.
B. In blue/green, current applications are slowly replaced with new ones. In canary, both old and new applications are in production at the same time.
C. In blue/green, both old and new applications are in production at the same time. In canary, the application Is deployed incrementally to a select group of people.
D. In blue/green, the application Is deployed In minor Increments to a select group of people. In canary, both old and new applications are simultaneously in production.

Answer: C

Explanation:
The correct answer is: In blue/green deployment, both old and new applications are in production at the same time. In canary deployment, the application is deployed incrementally to a select group of people. In a blue/green deployment strategy, two identical environments, referred to as blue and green, are set up. The current production environment (blue) continues to serve live traffic while a new version of the application is deployed in the green environment. Once the new version is tested and deemed stable, traffic is routed from the blue environment to the green environment, making it the new production environment. This approach allows for a seamless switch between the old and new versions of the application. On the other hand, in a canary deployment strategy, the new version of the application is deployed incrementally to a small subset of users or a specific group. This allows for testing the new version in a real production environment while minimizing the impact of any potential issues. If the new version performs well and meets the desired criteria, it can be gradually rolled out to a larger audience or the entire user base. In summary, the main difference between blue/green and canary deployment strategies lies in how the deployment is managed. Blue/green involves simultaneous production of both old and new applications, while canary deployment focuses on incremental deployment to a select group of users.

NEW QUESTION # 68
From a DevOps process standpoint, it is a good practice to keep changes to an application under version control. Which of the following allows changes to a Docker image to be stored in a version control system?

A. Updating docker-compose.yml
B. Updating Dockerfile
C. Executing docker save
D. Executing docker commit

Answer: D

Explanation:
The option that allows changes to a Docker image to be stored in a version control system is: docker commit The docker commit command is used to create a new image from a container's changes. It takes a running container as input, captures the changes made to it, and creates a new image with those changes. This new image can then be tagged and pushed to a registry, or saved locally. By using docker commit, you can effectively capture the changes made to a container as a new image and store it in a version control system along with the Dockerfile and other project files. This allows for reproducibility and traceability of changes to the Docker image over time.

NEW QUESTION # 69
You are a developing a microservices application that will be a consumer of the Oracle Cloud Infrastructure (OCI) Streaming service. Which API method should you use to read and process a stream?

A. ReadMessages
B. ProcessStream
C. ReadStream
D. GetMessages
E. GetStream

Answer: D

Explanation:
The correct API method to read and process a stream in the Oracle Cloud Infrastructure (OCI) Streaming service is "GetMessages". When consuming messages from a stream in OCI Streaming, you use the "GetMessages" API method. This method allows you to retrieve a batch of messages from the stream for processing. You can specify parameters such as the number of messages to retrieve, the maximum size of the messages, and the timeout for the request. By using the "GetMessages" API method, you can retrieve messages from the stream and then process them in your microservices application. This allows you to consume and handle the data in real-time as it becomes available in the stream. The "GetMessages" method provides flexibility in how you consume and process the messages, enabling you to implement custom logic and workflows based on your specific application requirements.

NEW QUESTION # 70
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. us-ashburn-1.ocir.io/heyoci/myproject/myapp:0.0.2-beta
B. us-ashburn-1.ocir.io/heyoci/myapp:0.0.2-beta
C. us-ashburn-1.ocir.io/myproject/heyoci/myapp:latest
D. iad.ocir.io/heyoci/myapp:0.0.2-beta
E. iad.ocir.io/heyoci/myproject/myapp:0.0.1
F. iad.ccir.io/heyoci/myapp:latest

Answer: A,E,F

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>.
