Disaster Recovery Objectives and Methods Questions

Covers the core goals and recovery approaches for recovering systems after a failure. Candidates should understand Recovery Time Objective which defines how quickly systems must be restored, and Recovery Point Objective which bounds acceptable data loss. Describe and compare recovery methods such as cold standby, warm standby, and hot standby including their cost, complexity, and expected recovery times. Discuss how to choose an approach based on business impact analysis, critical path dependencies, and cost versus risk trade offs. Explain runbooks and failover orchestration, automation of recovery procedures, validation and regular testing of recovery plans, metrics and monitoring for recovery readiness, and operational considerations for maintaining standby systems and exercising failover in production-like tests.
