Which components comprise a comprehensive disaster recovery approach for deployments?

• A. Backups, cross-region replication, defined RTO/RPO, and tested failover procedures.
• B. Backups only.
• C. Defined RTO/RPO only.
• D. Cross-region replication only.

Answer: (A)

Disaster recovery requires data protection, geographic resilience, defined targets, and validated recovery procedures. Backups create restore points so you can recover data to a known good state. Cross-region replication ensures copies exist in multiple locations, enabling service continuity even if one region goes down. Defining recovery time objectives (RTO) and recovery point objectives (RPO) sets clear, measurable goals for how quickly you must restore services and how much data you can afford to lose, guiding design decisions and investments. Testing failover procedures is the essential step that proves the plan works in practice, reveals hidden issues in automation and operations, and builds confidence for real incidents. When combined, these elements form a comprehensive disaster recovery approach that protects data, maintains availability across regions, and ensures you can meet your stated recovery goals.
