Cloud-Based Disaster Recovery Plans Questions and Answers for Viva

Answer-1: A strategy using cloud services to restore critical data and applications after a disaster.

Answer-2: It offers scalability, cost-efficiency, and faster recovery without requiring duplicate on-prem infrastructure.

Answer-3: Recovery Time Objective ? the target time to restore a service after a disruption.

Answer-4: Recovery Point Objective ? the maximum acceptable data loss measured in time.

Answer-5: By ensuring minimal downtime and data loss during failures using cloud replication and failover.

Answer-6: Backup and restore, pilot light, warm standby, and multi-site active-active.

Answer-7: Data is backed up to the cloud and restored during recovery; lowest cost but slowest recovery.

Answer-8: A minimal version of the environment is always running in the cloud, ready to scale when needed.

Answer-9: A scaled-down but fully functional environment is always running and can scale up quickly.

Answer-10: Multiple environments run simultaneously in different regions, offering instant failover.

Answer-11: Switching operations from a failed system to a backup system automatically or manually.

Answer-12: Failback is returning operations to the primary environment once it's restored.

Answer-13: AWS Elastic Disaster Recovery, Azure Site Recovery, and Google Cloud Backup and DR.

Answer-14: It replicates servers to AWS and allows launching recovery instances during failover.

Answer-15: A service that replicates workloads from on-prem or other clouds to Azure for disaster recovery.

Answer-16: At least annually or after major system changes.

Answer-17: Simulating a disaster to validate the recovery procedures and performance metrics.

Answer-18: It reduces recovery time and human errors through scripted, repeatable recovery processes.

Answer-19: Natural disasters, cyberattacks, hardware failure, or human error.

Answer-20: Snapshots capture the state of resources for quick restore or replication.

Answer-21: It stores backups, snapshots, and replicated data across multiple regions securely.

Answer-22: Copying data across regions to ensure availability even if one region fails.

Answer-23: Improved fault tolerance, availability, and compliance with regional regulations.

Answer-24: By choosing suitable DR models (like pilot light) to balance cost and recovery speed.

Answer-25: A document detailing step-by-step instructions for executing a disaster recovery process.

Answer-26: Identity and Access Management ensures only authorized users can access and trigger recovery systems.

Answer-27: A DR technique where data changes are continuously captured and replicated.

Answer-28: Meeting RTO, RPO, minimal downtime, and data integrity.

Answer-29: Disaster Recovery as a Service ? a cloud solution that manages DR planning and execution for you.

Answer-30: It reduces the need for complex in-house DR infrastructure and expertise.

Answer-31: Standards like GDPR, HIPAA, or ISO 27001 may mandate specific DR practices.

Answer-32: Service Level Agreements define recovery expectations, influencing the DR strategy.

Answer-33: Prolonged downtime, data loss, customer dissatisfaction, and regulatory penalties.

Answer-34: Backup stores data copies; DR restores systems and operations using those backups.

Answer-35: Versioning stores multiple iterations of data to allow recovery from the desired restore point.

Answer-36: A backup that cannot be altered or deleted, protecting against ransomware.

Answer-37: Recovering data from a specific moment to reverse errors or corruption.

Answer-38: It ensures data and systems are duplicated in multiple locations for higher availability.

Answer-39: Limited bandwidth can slow replication and recovery time, affecting RTO.

Answer-40: Automating the recovery steps, including boot order, network configuration, and dependencies.

Answer-41: Containers can be restored quickly using container images and orchestrators like Kubernetes.

Answer-42: Yes, though SaaS vendors typically manage DR, organizations should confirm their RTO/RPO.

Answer-43: Monitoring detects failures or threats that trigger the disaster recovery plan.

Answer-44: Enables consistent and quick redeployment of infrastructure during recovery.

Answer-45: Clear communication is critical to coordinate recovery and inform stakeholders.

Answer-46: Recovery of specific application services rather than full system recovery.

Answer-47: Combines on-prem and cloud-based recovery for flexibility and cost control.

Answer-48: To ensure all team members know procedures and responsibilities during a disaster.

Answer-49: Data consistency, cost management, bandwidth limits, and compliance.

Answer-50: Increased automation, AI-based anomaly detection, and tighter integration with DevOps pipelines.
