The complete practice exam for the Oracle Cloud Infrastructure 2026 Architect Professional certification (exam 1Z0-997-26, current 2026 version). It covers Architecting High Availability and Disaster Recovery Solutions (regions, availability and fault domains, OCI Full Stack Disaster Recovery, RTO/RPO-driven active-active, active-passive and pilot-light patterns, cross-region replication and Data Guard), Architecting Cloud-Native Solutions (Container Registry, Container Instances and Container Engine for Kubernetes, OCI Functions, API Gateway, Events, Queue and Streaming for event-driven designs), Implementing Infrastructure as Code (Terraform with the OCI provider, remote state, and OCI Resource Manager stacks, drift detection and landing zones), Implementing and Operating Databases in OCI (Base Database Service, Autonomous Database, Exadata, Data Guard and database HA/DR), Architecting Security Solutions (IAM and identity domains, compartments and policies, Cloud Guard, Security Zones and Zero Trust Packet Routing, Bastion, Network Firewall and Web Application Firewall, Vault and the Certificates service), Designing for Hybrid and Multicloud Architectures (Dynamic Routing Gateway, Site-to-Site VPN and FastConnect, Oracle Interconnect for Azure, Oracle Database@Azure and Oracle Cloud VMware Solution), Migrating Workloads, Databases and Data to OCI (the 6 Rs, Oracle Cloud Migrations, Zero Downtime Migration, GoldenGate and Roving Edge), and Implementing Observability Solutions (Monitoring and alarms, Logging and Logging Analytics, Service Connector Hub, Notifications and Application Performance Monitoring) — every question a real-world OCI architecture scenario with full explanations.

Who Should Take This Exam?

The OCI 2026 Architect Professional (1Z0-997-26) is designed for senior cloud architects, solution architects, and infrastructure leads who design, deploy, and operate enterprise-grade solutions on Oracle Cloud Infrastructure — spanning high availability and disaster recovery, cloud-native and serverless application platforms, Infrastructure as Code, database design, security architecture, hybrid and multicloud connectivity, migration, and observability. It validates advanced, hands-on architecture skills, so practical experience designing OCI solutions across compute, storage, networking, databases, and security is strongly recommended. It builds directly on the OCI Architect Associate certification.

Prerequisites: None (OCI Architect Associate-level knowledge plus hands-on experience architecting OCI solutions recommended)

Typical study time: 6-10 weeks of focused study

Exam Quick Facts

Exam Domains & Weights

The OCI-ARCHITECT-PROFESSIONAL exam covers 8 domains. Focus your study time based on the weights below — higher-weighted domains have more exam questions.

💡 Study tip: The two heaviest domains tie at 15% each — Architect Security Solutions (IAM, Vault, Network Firewall, WAF, Cloud Guard, Zero Trust Packet Routing) and Design for Hybrid and Multicloud Architectures (DRG, FastConnect, Oracle Interconnect for Azure, Oracle Database@Azure, Oracle Cloud VMware Solution). With Architect Cloud-Native Solutions (14% — OKE, Functions, API Gateway, event-driven design) close behind, those three are over 40% of the exam, so start there. The professional exam assumes Architect Associate-level networking, compute, and storage knowledge, so brush up on the associate fundamentals before diving into the advanced HA/DR, IaC, database, migration, and observability domains.
