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

NEW QUESTION # 66
Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics via Oracle Cloud Infrastructure (OCI) Monitoring. Which TWO metrics are collected and made available by this feature? (Choose two.)

A. Amount of RAM used by a function
B. Length of time a function runs
C. Number of times a function is invoked
D. Amount of CPU used by a function
E. Number of times a function Is removed

Answer: A,D

Explanation:
The correct answers are: Amount of RAM used by a function: Oracle Functions collects and reports the amount of memory (RAM) used by a function during its execution. This metric helps in monitoring and optimizing the resource consumption of functions. Length of time a function runs: Oracle Functions captures and provides the duration of function executions. This metric allows you to track the performance and responsiveness of your functions and identify any potential bottlenecks or delays. These metrics provide valuable insights into the resource utilization and performance of your functions, enabling you to monitor and optimize their behavior in the Oracle Cloud Infrastructure (OCI) environment.

NEW QUESTION # 67
Which term describes a group formed by a master machine and a worker machine in a Kubernetes architecture?

A. Container
B. Deployment
C. Cluster
D. Node
E. Pod

Answer: C

Explanation:
The term that describes a group formed by a master machine and a worker machine in a Kubernetes architecture is "Cluster". A cluster in Kubernetes consists of one or more master machines and multiple worker machines (also known as nodes). The master machine manages the overall control plane and orchestrates the deployment and management of containers on the worker nodes. The worker nodes are responsible for running the containers and executing the workloads. The cluster is the fundamental unit of organization and management in Kubernetes, providing the infrastructure and resources to run and manage containerized applications. It ensures high availability, scalability, and fault tolerance for the applications deployed within it.

NEW QUESTION # 68
What is the open source engine for Oracle Functions?

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

Answer: B

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 # 69
A company is developing a new application that needs to process transactions in real time. The company wants to ensure that all transactions are processed in order and that no transaction is lost. Which of these is a correct strategy for leveraging OCI Queue in this scenario?

A. Use a single queue to process all transactions.
B. Use a separate queue for each application instance.
C. Use a priority queue to prioritize requests.
D. Use a separate queue for each type of transaction.

Answer: A

Explanation:
OCI Queue is a service for enabling asynchronous (decoupled) communication in a serverless manner3. Queue handles high-volume transactional data that requires independent processing without loss or duplication3. Queue supports ordering of messages within a queue by using the FIFO (first-in-first-out) delivery option3. Therefore, using a single queue to process all transactions ensures that all transactions are processed in order and that no transaction is lost. Verified Reference: Overview of Queue

NEW QUESTION # 70
You have been asked to update an OKE cluster to a network configuration that has the least attack surface while the deployed applications are still directly available for access from the Internet. Which is a valid OKE cluster network configuration that meets this requirement? (Choose the best answer.)

A. Private subnets for nodes; public subnets for the Kubemetes API endpoint and load balancers
B. Private subnets for nodes and the Kubemetes API endpoint; public subnets for load balancers
C. Private subnets for nodes, the Kubemetes API endpoint, and load balancers
D. Private subnet for the Kubemetes API endpoint; public subnets for nodes and load balancers

Answer: B

Explanation:
The valid OKE cluster network configuration that meets the requirement of having the least attack surface while still allowing direct access to the deployed applications from the Internet is: Private subnets for nodes and the Kubernetes API endpoint; public subnets for load balancers. By placing the nodes and the Kubernetes API endpoint in private subnets, they are not directly accessible from the Internet, reducing the attack surface. The load balancers, on the other hand, are placed in public subnets, allowing them to be accessed from the Internet and serve as the entry point for accessing the deployed applications. This configuration ensures that the critical components of the cluster, such as the nodes and the API endpoint, are protected within the private network, while still providing accessibility to the applications through the load balancers. It helps to enhance security by limiting direct access to the internal components of the cluster while maintaining the availability of the deployed applications.

NEW QUESTION # 71
......
