Multicloud Fundamentals and Oracle Interconnect for Microsoft Azure
Explain the OCI-Azure Interconnect architecture, including FastConnect and ExpressRoute components, peering locations, and redundancy options, from memory without notes.
Compare OCI and Azure core services (compute, storage, networking, identity) and identify which multicloud use cases each platform is best suited for.
Diagram a reference multicloud topology with OCI VCN, Azure VNet, and Interconnect, labeling all gateways, route tables, and redundancy paths.
List the prerequisites and ordering of steps to provision an OCI-Azure Interconnect, including required CIDR planning and subscription setup.
Your checkpoint
A one-page architecture diagram and a 10-bullet checklist of Interconnect provisioning steps, both self-reviewed for accuracy.
Multicloud Fundamentals and Oracle Interconnect for Microsoft Azure & Networking for Multicloud Architectures
Configure a simulated OCI VCN and Azure VNet with non-overlapping CIDRs, subnets, and route tables in a lab or design document.
Describe how OCI-Azure Interconnect maps to FastConnect virtual circuits and ExpressRoute circuits, including bandwidth and SLA implications.
Identify common failure modes (BGP session down, route propagation delay, overlapping CIDRs) and propose mitigation for each.
Draft a troubleshooting runbook for Interconnect connectivity issues that includes verification commands and escalation paths.
Your checkpoint
A troubleshooting runbook with at least five failure scenarios and step-by-step resolution actions.
Networking for Multicloud Architectures
Design a hub-and-spoke multicloud network with OCI DRG and Azure Virtual WAN, documenting traffic flows for east-west and north-south traffic.
Explain how to use OCI Network Load Balancer, Azure Load Balancer, and private DNS across clouds to support application failover.
Configure and validate security lists, network security groups, and route rules in a lab scenario to permit only required traffic.
Compare private vs public connectivity options for multicloud data transfer and select the appropriate one for a given latency and compliance requirement.
Your checkpoint
A network design document with traffic-flow matrix and security-rule justification for three application tiers.
Identity and Security in Multicloud Deployments
Map OCI IAM policies, compartments, and dynamic groups to Azure AD roles and service principals for a multicloud identity federation design.
Configure OCI IAM identity federation with Azure AD and test single sign-on and group-based authorization in a lab.
Explain how OCI Vault and Azure Key Vault can be used for secrets management across clouds, including key rotation and access control.
Describe data-in-transit and data-at-rest encryption options across OCI and Azure Interconnect, including MACsec and private endpoint usage.
Your checkpoint
An identity and security architecture diagram with a RACI table showing who manages which identity and key resources in each cloud.
Identity and Security in Multicloud Deployments
Design a least-privilege access model for a multicloud deployment, including compartment structure, policy statements, and Azure RBAC assignments.
List the audit and logging sources across OCI and Azure (OCI Audit, Azure Monitor, Activity Log) and describe how to centralize them.
Identify compliance and data residency considerations when data crosses the Interconnect and propose controls to address them.
Create a threat model for a multicloud application that includes identity, network, and data-store attack paths.
Your checkpoint
A security control matrix mapping at least 10 controls to OCI and Azure implementation details.
Multicloud Database and Application Architectures (Autonomous Database, Database Service, WebLogic)
Design a multicloud database architecture using Autonomous Database in OCI with an application tier in Azure, including latency and connection-pooling considerations.
Explain how to use OCI Database Service (VM DB systems) for workloads requiring custom configurations, and compare with Autonomous Database.
Describe data replication options between OCI and Azure databases and select one for a given RPO/RTO requirement.
Configure a WebLogic domain in OCI and describe how it can front-end Azure-hosted services or consume OCI database services securely.
Your checkpoint
A database architecture decision record comparing Autonomous Database, Database Service, and WebLogic deployment options for two scenarios.
Multicloud Database and Application Architectures (Autonomous Database, Database Service, WebLogic) & Multicloud Fundamentals and Oracle Interconnect for Microsoft Azure
Design an end-to-end multicloud application with web tier in Azure, database tier in OCI, and Interconnect connectivity, documenting all components.
Produce a failure-mode and effects analysis (FMEA) for the end-to-end design, covering network, identity, and database failure domains.
Estimate cost implications of the design, including Interconnect port hours, data egress, and database licensing.
Present the design in a 10-minute recorded walkthrough, defending key trade-offs.
Your checkpoint
A complete solution design package (diagram, FMEA, cost estimate) and a recorded 10-minute presentation.
Multicloud Fundamentals and Oracle Interconnect for Microsoft Azure & Networking for Multicloud Architectures & Identity and Security in Multicloud Deployments & Multicloud Database and Application Architectures (Autonomous Database, Database Service, WebLogic)
Complete a timed 60-question practice exam covering all four domains and score at least 80%.
Review every missed question and write a one-paragraph explanation of the correct concept for each.
Revisit weak areas identified by practice results and update the personal cheat sheet for each domain.
Summarize the top 10 exam traps and the decision criteria for each major architecture choice.
Your checkpoint
A personal exam cheat sheet (one page per domain) and a practice exam score report with remediation notes.
