OCI Multicloud Architect Professional study guide
OCI Multicloud Architect Professional · Work through your exam, one topic at a time.
The Oracle Cloud Infrastructure 2023 Multicloud Architect Professional is a professional-level certification exam identified by the code 1Z0-1115-23 and listed by Oracle University. It targets architects and senior engineers who design and operate workloads that span Oracle Cloud Infrastructure and Microsoft Azure, rather than single-cloud specialists. Typical candidates already hold OCI foundations or associate-level credentials and now need to reason about cross-cloud interconnect, routing, identity federation, and data-tier placement. The subject matter clusters into four areas: multicloud fundamentals and the Oracle Interconnect for Microsoft Azure; networking for multicloud architectures; identity and security in multicloud deployments; and multicloud database and application architectures covering Autonomous Database, Oracle Database Service, and WebLogic. The OCI Multicloud Architect Professional study guide has 4 sections and about 1,517 words.
01Multicloud Fundamentals and Oracle Interconnect for Microsoft Azure
This domain tests whether you can design a private OCI–Azure connection and explain what the interconnect does-and does not-provide. The exam expects fluency with paired regions, FastConnect/ExpressRoute concepts, DRG attachment, route tables, and the difference between network plumbing and managed database services.
381 words, about 2 min02Networking for Multicloud Architectures
This domain tests the packet path: OCI VCN route tables, security lists and NSGs, DRG route tables, Azure VNet route tables/UDRs and NSGs, private DNS, and hub-and-spoke transit. The exam wants you to prove that both clouds can forward and filter the same flow symmetrically.
382 words, about 2 min03Identity and Security in Multicloud Deployments
This domain tests authentication versus authorization across OCI IAM and Microsoft Entra ID, plus workload identity, network security, encryption, and audit. The exam expects you to keep a single identity source and apply least privilege in each cloud.
359 words, about 2 min04Multicloud Database and Application Architectures (Autonomous Database, Database Service, WebLogic)
This domain tests placing Oracle data services and WebLogic application tiers across OCI and Azure without breaking latency, security, or recovery. Know the managed options and the connectivity they require.
