Concept, implementation, and troubleshooting questions with model answers, evaluation points, follow-ups, and weak-answer warnings.
Open question setBackup and Disaster Recovery
Expect clear distinction between high availability, replication, backup, and DR; objective measurement; consistency; immutable copies; orchestration; dependency order; split-brain prevention; and tested recovery.
Interview focus
Answer with mechanism, evidence, and trade-offs
Expect clear distinction between high availability, replication, backup, and DR; objective measurement; consistency; immutable copies; orchestration; dependency order; split-brain prevention; and tested recovery.
Strong-answer signals
- Differentiate backup, restore, replication, and DR
- Set RTO and RPO
- Use Azure Backup and Site Recovery
- Design multi-region architecture
- Run failover, failback, and DR testing

Practical interview scenario
Design, diagnose, and defend your decision
A ransomware event corrupts production and the corruption has replicated to the secondary region. Restore service while meeting RTO/RPO and preserving forensic evidence.
A complete response should include
- Business impact and technical constraints
- Architecture or execution sequence
- Identity, security, and evidence
- Failure handling and recovery
- Metrics and next improvement
Module question spotlight
Five questions to practise first
01BackupWhat problem does Backup solve, how does it work in Backup and Disaster Recovery, and what is it commonly confused with?
Define the mechanism and ownership boundary first. Explain that it preserves durable information with explicit ownership, consistency, access, lifecycle, replication, and recovery guarantees, then contrast it with the adjacent responsibilities represented by the module prerequisites and the following Restore concept. Close with a concrete validation signal.
02RestoreHow would you implement and validate Restore for a production workload?
Start from workload constraints and existing state. Establish impact, collect discriminating evidence, isolate the failing layer, apply the smallest safe mitigation, validate recovery, and record prevention. Include identity, dependencies, normal and failure tests, monitoring, and an explicit recovery decision.
03RTOA change involving RTO causes a production symptom. What evidence would you inspect and how would you recover safely?
Establish scope and recent change, inspect the native configuration and event or log evidence, test the dependency boundary, apply the smallest reversible mitigation, verify user impact has recovered, and retain the findings for permanent prevention.
04RPOWhat problem does RPO solve, how does it work in Backup and Disaster Recovery, and what is it commonly confused with?
Define the mechanism and ownership boundary first. Explain that it provides a concrete platform capability that must be configured, secured, validated, observed, and owned throughout its lifecycle, then contrast it with the adjacent responsibilities represented by the preceding RTO concept and the following Azure Backup concept. Close with a concrete validation signal.
05Azure BackupHow would you implement and validate Azure Backup for a production workload?
Start from workload constraints and existing state. Classify the data, select storage and redundancy, secure access, test write and read behavior, and prove backup or recovery against an objective. Include identity, dependencies, normal and failure tests, monitoring, and an explicit recovery decision.
