Which Azure feature protects Azure Blob Storage data from accidental deletion by retaining deleted data for a configurable retention period?
Answer: Soft Delete for Blobs
Soft Delete for Blobs retains deleted blobs and snapshots for a configurable period (1–365 days), allowing recovery from accidental or malicious deletions.
Azure Site Recovery replicates Azure VMs to a secondary region. What is the typical RPO target achievable with ASR for Azure VM replication?
Answer: Less than 15 seconds
ASR for Azure VMs targets an RPO of less than 15 seconds for app-consistent recovery points, using continuous replication with very frequent checkpoint intervals.
What type of Azure Site Recovery recovery point captures the application state (in-memory data and pending transactions) in addition to disk state?
Answer: App-consistent recovery point
App-consistent recovery points use VSS (Volume Shadow Copy Service) to flush in-memory data and pending I/O, ensuring database and application consistency at the recovery point.
An organization needs to back up on-premises servers and Azure VMs to a centralized vault. Which Azure service manages this?
Answer: Azure Backup with Recovery Services Vault
Azure Backup with Recovery Services Vault provides centralized backup management for Azure VMs, on-premises servers, SQL Server, SAP HANA, and Azure Files.
Which Azure Backup feature prevents backup data from being deleted even if the vault is accidentally deleted by an unauthorized user?
Answer: Multi-User Authorization (MUA)
Multi-User Authorization (MUA) for Azure Backup requires a second approver from a designated Resource Guard to perform destructive backup operations, protecting against insider threats.
A solution requires that in a regional outage, the application automatically fails over to a secondary region with no manual intervention. Which design pattern achieves this?
Answer: Active-active with Azure Front Door and auto-failover groups
Active-active with Azure Front Door and SQL auto-failover groups enables automatic traffic redirection and database failover without human intervention when a region becomes unavailable.
