Read the first 6 Azure Business Continuity and Disaster Recovery Design flashcards as text

  1. Your organization needs automated, policy-driven backup for all Azure VMs across 20 subscriptions from a single interface. Which Azure service provides this centralized management?

    Answer: Azure Backup Center with a Backup policy at management group scope

    Azure Backup Center provides a unified view and governance console to monitor, manage, and enforce backup policies across multiple vaults and subscriptions.

  2. An Azure SQL Managed Instance needs to meet an RPO of 1 hour and an RTO of 4 hours for cross-region disaster recovery. Which feature should you configure?

    Answer: Auto-failover groups with a secondary in a paired region

    Auto-failover groups for SQL Managed Instance continuously replicate data to a secondary region and support automated or manual failover to meet RTO/RPO requirements.

  3. You need to design a backup strategy for Azure Blob Storage where accidental deletions can be recovered within 30 days. Which feature provides this at no additional storage cost for the retention period?

    Answer: Azure Blob soft delete

    Blob soft delete retains deleted blobs for a configurable retention period and is built into Azure Blob Storage without requiring a separate backup vault.

  4. Which Azure Cosmos DB feature provides continuous backup and allows you to restore your database to any point in the past 30 days?

    Answer: Continuous backup mode with point-in-time restore (PITR)

    Cosmos DB Continuous backup mode captures changes continuously allowing point-in-time restore to any second within the past 30 days.

  5. Your organization's RPO for a critical application is zero — no data can be lost. Which Azure SQL Database deployment option meets this requirement?

    Answer: Azure SQL Database Business Critical tier with zone-redundant configuration

    SQL Database Business Critical uses synchronous replication across Availability Zones so all committed transactions are written to multiple nodes before acknowledgment, ensuring RPO=0.

  6. You need to design a recovery solution for an AKS cluster where the entire cluster must be recoverable in a new region within 2 hours. What should your DR plan include?

    Answer: GitOps with infrastructure-as-code (Bicep/Terraform) + Azure Backup for persistent volumes

    Storing AKS manifests and IaC in a repo (GitOps) allows rapid cluster rebuild while Azure Backup for persistent volumes restores stateful data to meet a 2-hour RTO.
