  1. A financial services company needs to migrate a legacy on-premises SQL Server to Azure while ensuring zero data loss and minimal downtime during cutover. Which migration approach is most appropriate?

    Answer: Azure Database Migration Service in online mode

    Azure Database Migration Service in online mode enables continuous data sync and minimal-downtime cutover for SQL Server migrations.

  2. A retail company's e-commerce platform experiences traffic spikes of 10x normal load during holiday sales. The solution must auto-scale and minimize cost during off-peak hours. Which architecture best addresses this?

    Answer: Azure App Service with auto-scale rules tied to CPU and HTTP queue length

    Azure App Service auto-scale rules based on CPU and HTTP queue metrics allow elastic scaling that matches demand and reduces costs when idle.

  3. A healthcare organization must ensure patient data stored in Azure Blob Storage is encrypted with customer-managed keys and that key access can be revoked immediately if a breach is detected. What should the architect configure?

    Answer: Azure Key Vault with customer-managed keys, purge protection enabled, and storage account CMK integration

    CMK integration with purge protection ensures data becomes inaccessible upon key revocation while preventing accidental permanent key deletion.

  4. A global media company streams video content to users worldwide. Latency must be under 50ms for 95% of users. Which Azure service combination is most appropriate?

    Answer: Azure Front Door with Azure CDN and geo-distributed storage using Azure Media Services

    Azure Front Door provides global load balancing and acceleration, while CDN edge nodes cache content close to users to minimize latency.

  5. An enterprise migrates a three-tier application to Azure. The web tier must be publicly accessible, but the application and database tiers must only communicate internally. Which design enforces this isolation?

    Answer: Deploy web tier in a public subnet, app and DB tiers in private subnets within the same VNet, with NSGs restricting traffic between subnets

    Using public and private subnets with NSGs in a single VNet enforces tier isolation while allowing controlled internal communication.

  6. A manufacturing company needs near-real-time analytics on IoT sensor data from 50,000 devices. The solution must handle millions of events per second and enable ad-hoc SQL queries. Which pipeline is correct?

    Answer: IoT Hub → Azure Stream Analytics → Azure Synapse Analytics

    IoT Hub ingests device data, Stream Analytics processes events in real-time, and Synapse Analytics enables SQL-based analytics at scale.

  7. A company's DR plan requires an RTO of 15 minutes and an RPO of 5 minutes for a critical Azure SQL Database workload. Which configuration achieves this?

    Answer: Active geo-replication with auto-failover groups configured

    Active geo-replication with auto-failover groups provides automatic failover meeting a 15-minute RTO with continuous log shipping achieving near-zero RPO.
