Master the Oracle Cloud Infrastructure 2025 Developer Professional exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle Oracle Cloud Infrastructure 2025 Developer Professional exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Oracle Cloud Infrastructure 2025 Developer Professional
OCI Service Mesh is correct because it provides a dedicated infrastructure layer for handling service-to-service communication, including automatic retries, circuit breakers, traffic management, and observability without requiring changes to application code. API Gateway is designed for external API management, not inter-service communication. Load Balancer provides traffic distribution but lacks advanced service mesh features like circuit breakers and automatic retries. Functions is a serverless compute service and doesn't provide service mesh capabilities.
OCI File Storage Service with ReadWriteMany access mode is correct because it supports concurrent read-write access from multiple pods, making it ideal for shared storage scenarios. Block Volumes only support ReadWriteOnce, meaning they can be mounted by a single pod at a time. emptyDir is ephemeral and tied to pod lifecycle, not suitable for persistent storage. hostPath binds to a specific node and doesn't provide the multi-pod access needed.
Resource Principal authentication with appropriate IAM policies is the correct and secure approach. Resource Principals allow OCI services like Functions to authenticate to other OCI services without requiring credential management in code. Embedding credentials in code, environment variables, or configuration files are all security anti-patterns that expose sensitive information and violate security best practices.
Deploying one consumer instance per partition, with each processing messages sequentially, is correct because it maintains message ordering within each partition (a key guarantee of streaming systems) while maximizing parallelism across partitions. A single consumer for all partitions reduces throughput. Random partition access by multiple consumers can cause ordering issues. Multiple threads processing the same partition concurrently breaks ordering guarantees within that partition.
OCI Monitoring service with custom alarms on function metrics is correct because it provides native metric collection for Functions including execution duration, and allows you to create alarms based on metric thresholds. While Logging can capture function logs, it's not designed for performance metric alerting. Events service is for event-driven automation, not metric-based monitoring. Notifications is the delivery mechanism but requires Monitoring or Events to trigger alerts.
