CompTIA Project+ (PK0-005)Basics of IT and GovernanceHard
A project manager is deploying a new service that needs to be highly available and resilient to regional outages. The service processes customer transactions globally, and data sovereignty regulations require that customer data from specific countries must remain within those countries' borders. Which cloud deployment strategy is MOST suitable for meeting these complex availability and compliance requirements?
- AMulti-region deployment with data residency controls
- BPrivate cloud deployment with global load balancing
- CSingle-region, multi-availability zone deployment
- DHybrid cloud deployment with on-premises data centers
Show answer & explanationAnswer & explanation
Correct answer: A. Multi-region deployment with data residency controls
Multi-region deployment with data residency controls allows the service to be deployed across multiple geographical regions for high availability and resilience, while ensuring that specific customer data is stored and processed only within the required sovereign borders.
Why the other options are wrong
- B. Private cloud deployment offers control but scaling it globally for high availability and data sovereignty across many countries is extremely complex and costly, and it doesn't leverage cloud providers' global infrastructure for resilience as effectively.
- C. Single-region, multi-availability zone improves resilience within a region but does not protect against a full regional outage or address data sovereignty across countries.
- D. Hybrid cloud can provide some resilience but doesn't inherently solve global data sovereignty or the specific need for resilience against *regional* cloud outages for a globally distributed service.
Multi-Region Deployment with Data Residency
A cloud strategy combining deployments in multiple geographical regions for high availability and disaster recovery, while specifically configuring data storage and processing to comply with data sovereignty laws of different countries.
- Ensures high availability and resilience against regional failures.
- Addresses data sovereignty by keeping data within specific national borders.
- Critical for global services with strict regulatory compliance.
Memory trick: Regions for resilience, residency for regulations.
