TheOracle Cloud Infrastructure 2025 Architect Professional exam validates advanced-level skills required to design, deploy, and manage enterprise-scale solutions on Oracle Cloud Infrastructure (OCI). This exam focuses on real-world architectural decision-making rather than basic service definitions. Candidates are tested on their ability to build secure, scalable, highly available, and cost-efficient cloud architectures aligned with modern business needs.

The exam emphasizes best practices, automation, governance, and performance optimization in OCI environments.

Exam Review

This is a professional-level certification, meaning the exam is scenario-based and analytical rather than theory-focused. Questions typically describe real infrastructure challenges and ask for the best architectural solution. Many questions require understanding trade-offs between cost, performance, security, and availability.

It is considered moderately difficult to difficult, especially for candidates without hands-on OCI experience. Memorization alone is not sufficient; practical understanding is essential.
