Focus on understanding why organizations choose Oracle Database@AWS instead of traditional hybrid cloud approaches.
2. Oracle Database@AWS Architecture and Onboarding (20%)
This is one of the most important sections in the exam and forms the foundation for understanding the complete Oracle Database@AWS ecosystem.
Architecture Topics to Master
- Oracle Database@AWS architecture overview
- OCI region extension into AWS
- Oracle-managed infrastructure
- Dedicated OCI-AWS connectivity
- Control plane and data plane understanding
AWS Components to Learn
- VPC
- Subnets
- Route Tables
- Security Groups
- Transit Gateway
- AWS IAM
OCI Components to Learn
- ODB Network
- ODB Peering
- VCN
- DRG
- OCI IAM
- Compartments
Oracle Database Services
- Oracle Exadata Database Service
- Autonomous Database
- Exadata VM Clusters
- Autonomous VM Clusters
Onboarding Preparation
- OCI tenancy requirements
- AWS account preparation
- IAM permissions
- Region compatibility
- Procurement workflow
- Subscription understanding
Many candidates ignore procurement and onboarding workflow concepts. Oracle may include scenario-based questions around subscription, tenancy, and account setup.
3. Configure Oracle Database@AWS Networking (15%)
Networking is one of the most critical areas of the certification exam.
Focus Areas
- ODB Network architecture
- Supported network topologies
- Private connectivity design
- DNS integration
- Traffic routing
- Security isolation
Networking Concepts to Practice
AWS Networking
- VPC routing
- Security Groups
- NACLs
- Transit Gateway
- Route propagation
OCI Networking
- VCNs
- DRGs
- NSGs
- Security Lists
- Route Tables
DNS Topics
- Route 53
- OCI DNS
- Private DNS Zones
- Hostname resolution
Spend extra time understanding routing flow between OCI and AWS because networking-based scenario questions are very common in architect-level certifications.
4. Provision and Operate Oracle Database@AWS Resources (20%)
This section focuses on practical deployment and operational workflows.
Learn These Provisioning Tasks
- Create ODB Network
- Create ODB Peering Connection
- Provision Exadata Infrastructure
- Create Exadata VM Clusters
- Create Autonomous VM Clusters
- Create Exadata Databases
- Create Autonomous Databases
Operational Topics
- Backup and restore
- Maintenance windows
- Database scaling
- Monitoring and alerts
- Observability architecture
Monitoring Services
- OCI Monitoring
- OCI Logging
- OCI Events
- AWS CloudWatch integration
5. Migrate Oracle Databases to Oracle Database@AWS (15%)
Migration is another important domain in this certification.
Oracle Zero Downtime Migration (ZDM)
You should clearly understand:
- ZDM architecture
- Migration prerequisites
- Supported source databases
- Physical and logical migrations
- Online and offline migration workflows
ZDM Migration Workflows
- Migration to Exadata Database Service
- Migration to Autonomous Database
- RMAN-based migrations
- Data Guard-based migrations
- Switchover and fallback procedures
Understand the sequence of migration steps rather than memorizing commands. Oracle often asks architecture and workflow-based questions.
6. HA and DR with Oracle Database@AWS (10%)
High Availability Topics
- Oracle RAC architecture
- Exadata High Availability
- Fault domains
- Infrastructure redundancy
Disaster Recovery Topics
- Oracle Data Guard
- Cross-region DR
- Backup-based DR
- RPO and RTO understanding
- Failover and switchover
7. Secure Oracle Database@AWS (15%)
IAM Topics
- OCI IAM
- AWS IAM
- Federation
- Policies and permissions
- Role-based access control
Data Protection
- Encryption at rest
- Encryption in transit
- OCI Vault
- Key Management
- Secrets management
Security Controls
- Network isolation
- Security Groups
- NSGs
- Audit logging
- Access control
OCI Well-Architected Framework
- Security
- Reliability
- Performance Efficiency
- Operational Excellence
- Cost Optimization
