Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Practice Exam: Test Your Knowledge 2025

A global retailer wants to deploy an application across Oracle Cloud Infrastructure (OCI) and another public cloud. The application has stateless web tiers, cloud-native databases in each cloud, and asynchronous data exchange between clouds. The primary design goal is to minimize tight coupling and avoid cross-cloud latency affecting user transactions. Which architecture is the best fit?

An enterprise wants a multicloud landing zone where application teams can independently deploy workloads in OCI and another cloud while central IT enforces governance, identity standards, and network guardrails. Which approach is most appropriate?

A company is modernizing an application portfolio and needs to decide which workloads should remain single-cloud and which should become multicloud. Which criterion most strongly justifies a multicloud design?

A financial services firm is designing a multicloud application that must meet strict regulatory requirements for data residency. User-facing services run in two clouds, but regulated customer data must stay in a specific OCI region. What is the best architecture decision?

A solutions architect is reviewing a proposed multicloud design. The design uses proprietary messaging, monitoring, and deployment tooling from both clouds directly in the application code. The company wants to preserve portability where practical. What should the architect recommend?

A company runs customer-facing APIs in OCI and data analytics in another cloud. During architecture review, the team discovers that the analytics platform frequently pulls large operational datasets across clouds every few minutes. Users are experiencing increased API latency and networking costs are rising. Which redesign is most appropriate?

A company wants users to sign in once using its corporate identity provider and access OCI resources without creating separate OCI passwords. Which OCI capability enables this pattern?

An organization federates OCI with a corporate identity provider. Security administrators want to ensure that access to OCI compartments is granted based on enterprise groups rather than individual users. What is the recommended approach?

A multicloud application runs containerized workloads in OCI and another cloud. The security team wants workloads to access OCI resources without storing long-lived user credentials in containers. Which approach is best?

A security architect is designing access for operations teams in a multicloud environment. The team needs read-only visibility into OCI resources, but only a smaller break-glass group should be able to modify production networking. Which IAM design best meets this requirement?

A company uses federated access to OCI from its enterprise identity provider. Users authenticate successfully, but a group of developers cannot launch instances in a specific compartment. Audit logs show successful authentication, but authorization failures occur on compute instance creation. What is the most likely cause?

A regulated enterprise must secure secrets used by applications deployed across OCI and another cloud. The applications need database credentials, API keys, and certificates with centralized governance, auditability, and rotation controls. Which strategy is most appropriate?

An enterprise needs private, high-bandwidth, low-latency connectivity between OCI and another cloud for production workloads. The architecture must avoid traversing the public internet. Which design is most appropriate?

A company connects its OCI VCN to another cloud. During implementation, engineers discover overlapping CIDR ranges between the two environments, preventing straightforward routing. What is the best long-term solution?

A multicloud application requires name resolution between private services in OCI and another cloud. Teams report intermittent failures because service names are only resolvable within their originating cloud. Which capability is most important to address this issue?

An architect must design network security for applications spanning OCI and another cloud. The requirement is to minimize lateral movement while allowing only required application flows between tiers. What is the best approach?

A company has private connectivity between OCI and another cloud, but application traffic intermittently fails after a recent expansion. Investigation shows that routes are present, yet return traffic sometimes follows a different path and is dropped by security controls. Which issue is the most likely cause?

A company operates a customer-facing platform across OCI and another cloud. Leadership wants a disaster recovery strategy that can tolerate the loss of one cloud provider for critical services. Which principle should guide the design?

An enterprise runs production in OCI and maintains standby services in another cloud. During a DR exercise, failover succeeds technically, but the incident response team struggles because monitoring dashboards, alert routing, and runbooks differ significantly between clouds. What operational improvement would most reduce this risk?

A business-critical application runs active-active across OCI and another cloud. The application uses asynchronous data replication and can continue operating during a cloud outage, but after failback the teams discover data conflicts between the two environments. Which design consideration was most likely insufficiently addressed?
