Multi Region and Multi Cloud Resilience Questions
Designing systems that work across multiple geographic regions or cloud providers. This addresses the highest reliability requirements and provides protection against provider-level failures. At senior level, understand data replication across regions, latency implications, consistency trade-offs, and cost of multi-region deployments. Design routing policies that direct traffic to healthy regions. Address compliance requirements that may mandate geographic distribution.

Design an automated cross-region backup and restore verification system for critical databases and object stores. Include scheduling, retention tiers, integrity verification (checksums), restore testing cadence (table-level vs full restore), and safe automation to avoid impacting production performance.

DNS TTLs and resolver caching affect failover time. Given a DNS record TTL of 60 seconds, explain realistic expectations for failover time after BGP-level routing changes or region health failure. What mitigations can make failover faster and more reliable?

Design a multi-cloud solution for a financial application that must keep personally identifiable information (PII) in Country A, but serve global compute across regions. Provide architecture for data partitioning, secure transit, KMS/key-scoping, audit trails, and how you'd enforce and validate compliance automatically.
