Understand the certification
Certification Overview
Oracle Cloud Infrastructure Architect Professional 2020 (1Z0-1072-20) is the professional-level OCI exam for people who design cloud architectures instead of just operating individual services. It checks whether you can make sensible design decisions across availability, networking, compute, storage, databases, and security, and explain why one OCI pattern fits better than another.
Exam Focus
- High Availability and Disaster Recovery: region design, DR strategies, failover patterns, and scaling decisions
- Networking Design: VCN layout, peering, FastConnect, VPN, and traffic routing
- Compute and Storage: instance selection, volume strategy, object storage, file storage, and containers
- Database Design: Autonomous Database, DB systems, Data Guard, migration, and service selection
- Security and Identity: IAM, key management, Cloud Guard, WAF, and compliance patterns
Who Is This For
This certification is a fit for OCI solution architects, cloud consultants, infrastructure designers, and technical professionals who need to plan Oracle cloud environments at a higher level than basic operations work.
