A company runs a critical application on Azure VMs in the West US region. They need to protect against a regional disaster using Azure Site Recovery. The VMs use unmanaged disks. The recovery point objective (RPO) must be 15 minutes and the recovery time objective (RTO) must be 1 hour. Additionally, they must be able to perform quarterly disaster recovery drills that do not affect the production environment. Which configuration should they use in Azure Site Recovery?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Set up replication with a 15-minute snapshot frequency and perform test failover for drills.. Azure Site Recovery supports replication of Azure VMs with unmanaged disks, and a 15-minute snapshot frequency meets the RPO requirement. Test failover allows quarterly disaster recovery drills without impacting the production environment, as it creates isolated copies of VMs in a separate network for validation.

Answer

Use Azure Backup for VM replication and perform restore drills.

Answer

Configure a recovery plan with a pre-script to take a snapshot every 15 minutes.

Answer

Enable multi-VM consistency group with a 15-minute consistency frequency.

Question 2

Your company, Fabrikam Inc., operates a global Software-as-a-Service (SaaS) application that provides real-time analytics. The application runs on Azure Kubernetes Service (AKS) with a microservices architecture. The data tier uses Azure Cosmos DB (Core SQL API) with multi-region writes. The application also uses Azure Event Hubs for event ingestion. The business requires a Recovery Time Objective (RTO) of 10 seconds and a Recovery Point Objective (RPO) of 0 for the entire platform. The solution must support active-active configuration across multiple Azure regions. You have been asked to recommend the disaster recovery design. Which option should you recommend?

Accepted Answer

Deploy AKS in three regions with Azure Front Door. Use Azure Cosmos DB with multi-region writes. Use Azure Event Hubs with geo-disaster recovery and active-active pattern. Use Azure Cache for Redis Enterprise with active geo-replication.. It meets the strict RTO of 10 seconds and RPO of 0 by using Azure Front Door for global load balancing with health probes, Azure Cosmos DB multi-region writes for zero data loss, Azure Event Hubs with geo-disaster recovery and active-active pattern for continuous event ingestion, and Azure Cache for Redis Enterprise with active geo-replication for synchronized caching across regions. This combination ensures that all components support active-active configuration and can fail over instantly without data loss.

Answer

Deploy AKS in three regions with Azure Traffic Manager. Use Azure Cosmos DB with multi-region writes. Use Azure Event Hubs with geo-disaster recovery. Use Azure Cache for Redis Enterprise with active geo-replication.

Answer

Deploy AKS in two regions with Azure Front Door. Use Azure Cosmos DB with single write region and auto-failover. Use Azure Service Bus with geo-disaster recovery. Use Azure Cache for Redis Enterprise with active geo-replication.

Answer

Deploy AKS in two regions with Azure Front Door. Use Azure SQL Database with auto-failover groups. Use Azure Event Hubs with geo-disaster recovery. Use Azure Cache for Redis Enterprise with active geo-replication.

Question 3

You are designing a connectivity solution for a hybrid network. The company has an on-premises network connected to an Azure virtual network via ExpressRoute. They also have a site-to-site VPN to the same Azure virtual network as a backup. When the ExpressRoute connection fails, traffic should automatically fail over to the VPN. How should you configure the routes to ensure automatic failover?

Accepted Answer

Ensure the ExpressRoute connection has a lower BGP metric than the VPN connection; Azure automatically prefers lower metric.. B is correct because when both ExpressRoute and VPN connections use BGP to advertise routes to Azure, Azure automatically selects the route with the lowest BGP metric (MED). By configuring the ExpressRoute connection with a lower BGP metric than the VPN connection, Azure will prefer the ExpressRoute path under normal conditions. If the ExpressRoute fails, its routes are withdrawn, and Azure falls back to the VPN routes, providing automatic failover.

Answer

Configure Azure Traffic Manager with a priority routing method to direct traffic to ExpressRoute first.

Answer

Set the BGP metrics (local preference) on the ExpressRoute connection to be higher than the VPN connection.

Answer

Configure Azure Route Server to propagate routes with a lower metric for the VPN connection.

Question 4

Your company plans to migrate a large number of on-premises virtual machines to Azure. You need to assess the current environment and migrate the workloads with minimal downtime. Which THREE Azure services or tools should you use? (Choose three.)

Accepted Answer

Azure Data Box. Azure Data Box is correct because it enables large-scale offline data transfer for environments with limited network bandwidth, allowing you to migrate terabytes of VM data to Azure without relying on slow or unstable connections. This service is ideal for the initial bulk copy of on-premises VM disks, which can then be used with Azure Migrate for assessment and Azure Site Recovery for ongoing replication with minimal downtime.

Answer

Azure App Service

Answer

Azure Import/Export Service

Question 5

A company is designing a disaster recovery solution for a critical application that runs on Azure VMs in a single region. The RTO is 4 hours, and the RPO is 1 hour. The application uses Azure SQL Database. The company wants to minimize the cost of the disaster recovery solution while meeting the RTO and RPO. You need to recommend a solution. What should you recommend?

Accepted Answer

Use Azure Site Recovery to replicate VMs to a secondary region and Azure SQL Database geo-replication for the database.. Azure Site Recovery provides orchestrated replication and failover for Azure VMs, meeting the 4-hour RTO with automated recovery plans. Azure SQL Database active geo-replication (or failover groups) enables continuous data synchronization with an RPO of 1 hour. This combination minimizes cost by using only the necessary replication services without over-provisioning resources.

Answer

Use Azure SQL Database active geo-replication for the database and Azure Backup for VMs.

Answer

Use Azure Backup to back up VMs and Azure SQL Database to a secondary region.

Answer

Use Azure Traffic Manager to distribute traffic to VMs in multiple regions and Azure SQL Database failover groups.

Question 6

A company needs to store and analyze petabytes of IoT telemetry data. The data is append-only and rarely updated. They require SQL-based querying and columnar storage for fast analytics. Which Azure storage solution should you choose?

Accepted Answer

Azure Data Lake Storage Gen2 with Azure Synapse SQL pool. Azure Data Lake Storage Gen2 (ADLS Gen2) provides hierarchical namespace and petabyte-scale storage optimized for big data analytics. When combined with Azure Synapse SQL pool (formerly SQL DW), it enables SQL-based querying over columnar storage (using PolyBase or CETAS) for fast analytics on append-only IoT telemetry data. This combination supports massive data volumes, append-only workloads, and columnar storage for high-performance analytical queries.

Answer

Configure Azure Autoscale for the VMs based on CPU metrics and use Azure Monitor for logging.

Answer

Deploy Application Insights on each VM and use its built-in alerts for performance.

Question 8

You run the above PowerShell script to upload a blob to Azure Storage. The script fails with an error: 'The specified container does not exist.' What should you do first to resolve the issue?

Accepted Answer

Create the container using New-AzStorageContainer.. The error 'The specified container does not exist' indicates that the target container has not been created in the Azure Storage account. The PowerShell script uses the `Set-AzStorageBlobContent` cmdlet, which requires an existing container as the destination. Therefore, the first corrective action is to create the container using `New-AzStorageContainer` before uploading the blob.

Answer

Use a different connection string with a SAS token.

Answer

Grant the storage account key access to the user.

Answer

Change the -StandardBlobTier parameter to Cool.

Question 9

A small business is migrating its on-premises file server to Azure. The file server contains 2 TB of data that is accessed infrequently. The business wants to minimize costs and only pay for storage used. The solution must support SMB protocol and allow for on-premises caching to reduce latency. Which Azure storage solution should the business recommend?

Accepted Answer

Azure Files Standard tier with Azure File Sync. Azure Files Standard tier with Azure File Sync is correct because it provides fully managed SMB file shares in the cloud, supports the required SMB protocol, and Azure File Sync enables on-premises caching to reduce latency. The Standard tier is cost-effective for infrequently accessed data, and the pay-as-you-go model minimizes costs by charging only for actual storage used.
