1Z0-997-25 Question 48
Single answerYou are designing a new e-commerce platform in Oracle Cloud Infrastructure (OCI) that must support users across multiple countries. The platform must comply with local data residency requirements, handle unpredictable traffic spikes, and remain cost-effective. Which approach best meets these business and technical requirements?
- A
Deploy to a single OCI region with multiple Availability Domains and replicate data to an on-premises data center for residency compliance.
- B
Create separate compartments in a single OCI region for each country and rely on compartment-level isolation for data residency.
- C
Adopt a multi-region design, deploying the application to each required local region and using a global load balancer to route traffic for performance and compliance.
- D
Use a single OCI region with a Standard Load Balancer fronting replicated backend servers to satisfy both availability and regulatory needs.
Show answer and explanation
Correct answer: C
Explanation
A multi-region deployment is often required when designing cloud solutions that must meet strict data residency demands and provide low-latency access across multiple countries. By deploying separate instances of the application in each relevant region, you ensure that user data remains within local boundaries, complying with regulations. OCI global load balancing capabilities can distribute user requests to the nearest region and improve performance. Refer to Oracle� documentation on OCI Regions and Governance (https://docs.oracle.com/en-us/iaas/Content/General/Concepts/regions.htm) for best practices around multi-region architecture.
- A. Incorrect.
Option 1 is incorrect. Simply placing resources in a single OCI region and replicating data on-premises does not fully address multi-country data residency requirements. Additionally, relying on on-prem infrastructure for compliance can introduce complex data transfers and higher operational overhead.
- B. Incorrect.
Option 2 is incorrect. Compartment-level isolation helps with administrative and cost control boundaries but does not ensure data residency compliance across different jurisdictions. All data remains within the same region, which can violate local regulation requirements.
- C. Correct.
Option 3 is correct. Distributing the application and data across multiple OCI regions located in the countries where your customers reside satisfies data locality demands. Using a global load balancer (e.g., OCI� Load Balancer or Global Load Balancing solutions) directs user requests to the geographically appropriate region, balancing performance and compliance needs.
- D. Incorrect.
Option 4 is incorrect. While using a single region with a Standard Load Balancer can address some high availability concerns, it does not fulfill multi-country data residency obligations. You do not have complete control over where data resides if everything is in one region.
