AZ-305 Design business continuity solutions Practice Test 2 — 15 Questions

Question 1

A company uses Azure Backup to protect on-premises Windows servers. The backup data is stored in a Recovery Services vault. They want to ensure that backup data is protected even if the entire Azure region fails. What should they configure?

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

Accepted Answer

Enable Cross-region restore (CRR) for the Recovery Services vault.. Cross-region restore (CRR) is the correct feature to protect backup data against an entire Azure region failure. When enabled on a Recovery Services vault with geo-redundant storage (GRS), CRR allows you to restore backup data to a paired secondary Azure region even if the primary region is unavailable. This ensures business continuity by providing a secondary restore point in a different region.

Answer

Configure backup replication across two Recovery Services vaults in different regions.

Answer

Enable geo-redundant storage (GRS) for the Recovery Services vault.

Answer

Use zone-redundant storage (ZRS) for the Recovery Services vault.

Question 2

Your company runs a critical application on Azure App Service. You need to design a disaster recovery solution that ensures the application is available in another region within 5 minutes of a regional failure. The application uses Azure SQL Database as its backend. The solution must minimize data loss and cost. What should you recommend?

Accepted Answer

Deploy App Service in two regions with Azure Traffic Manager. Use Azure SQL Database failover groups with active geo-replication.. It combines multi-region App Service deployment with Azure Traffic Manager for DNS-based traffic routing, enabling failover within minutes. Azure SQL Database failover groups with active geo-replication provide automatic, synchronous or asynchronous data replication to a secondary region, with an RPO of seconds and an RTO typically under 5 minutes during automatic failover. This meets the 5-minute availability target while minimizing data loss and cost through a managed, pay-per-use model.

Answer

Deploy App Service in one region with multiple instances. Use Azure SQL Database failover groups with manual failover.

Answer

Deploy App Service in two regions with Azure Front Door. Use Azure SQL Database with zone-redundant configuration.

Answer

Deploy App Service in two regions with Azure Traffic Manager. Use Azure SQL Database geo-restore for the database.

Question 3

Refer to the exhibit. An administrator configured Azure Site Recovery for a VM. The replication is ongoing but the health shows a warning. What is the most likely cause?

Accepted Answer

The Azure Site Recovery service does not have sufficient permissions to access the source VM or storage account.. The most likely cause of a replication health warning in Azure Site Recovery is insufficient permissions for the ASR service to access the source VM or storage account. This is a common configuration issue that prevents replication from completing successfully, resulting in a warning state.

Answer

The recovery point retention is set to 5 days, causing storage issues.

Answer

The replication provisioning state failed.

Answer

The replication interval is set to 15 minutes, exceeding the required RPO.

Question 4

A company wants to protect Azure VMs from accidental deletion or corruption by retaining daily backups for 30 days, weekly backups for 12 weeks, monthly backups for 12 months, and yearly backups for 7 years. Which backup policy type should they use?

Accepted Answer

Azure Backup GFS policy. Azure Backup's GFS (Grandfather-Father-Son) policy is specifically designed to support multiple retention tiers with different durations—daily, weekly, monthly, and yearly—all within a single backup policy. This matches the requirement for retaining daily backups for 30 days, weekly for 12 weeks, monthly for 12 months, and yearly for 7 years, which is a classic GFS retention model.

Answer

Daily backup policy with 30-day retention

Answer

Monthly backup policy with 12-month retention

Answer

Azure Backup Enhanced policy

Question 5

A company needs to design a disaster recovery solution for a multi-tier application that includes a web tier, a business tier, and a database tier. The solution must meet the following requirements:
- RPO of 15 minutes for the database
- RTO of 1 hour for the entire application
- Automatic failover for the database
- No data loss for the web and business tiers (stateless)
Which TWO services should be included in the solution? (Choose two.)

Accepted Answer

Azure Traffic Manager. Azure SQL Database active geo-replication (E) is correct because it provides a continuously replicated secondary database with an RPO of about 5 seconds (well within the 15-minute requirement) and supports automatic failover, satisfying the database RPO, RTO, and automatic failover needs. Azure Traffic Manager (B) is correct because it performs DNS-based global load balancing and health-probe-based automatic failover across regions, allowing traffic to be redirected to the secondary region so the stateless web and business tiers can recover within the 1-hour RTO without data loss. Azure Backup (A) is not suitable because it is a point-in-time backup/restore service with RPOs typically measured in hours, not the 15-minute RPO or automatic failover required. Azure Site Recovery (C) is not the best fit because it replicates VMs for orchestrated disaster recovery but does not provide the automatic database failover with a 15-minute RPO that active geo-replication delivers. Azure Front Door (D) is a global HTTP/HTTPS load balancer and CDN that can improve availability, but it does not provide the database replication or automatic failover required by the scenario.

Answer

Azure Backup

Answer

Azure Site Recovery for VM replication

Answer

Azure Front Door

Question 6

A healthcare organization stores patient records in Azure Blob Storage with a hot access tier in the East US region. The compliance policy requires that data be recoverable within 1 hour in the event of a regional disaster. The data is updated every 10 minutes and must be recoverable to a consistent state within 15 minutes of failure. Which configuration should you implement?

Accepted Answer

Use object replication with a minimum RPO of 15 minutes and configure read-access in the secondary region. Object replication with a minimum RPO of 15 minutes meets the compliance requirement to recover data to a consistent state within 15 minutes of failure, as it asynchronously replicates blobs with a configurable replication policy. Combined with read-access in the secondary region, it ensures data can be recovered within 1 hour during a regional disaster by allowing immediate reads from the secondary endpoint without waiting for failover.

Answer

Use RA-GRS (read-access geo-redundant storage) and configure storage account failover

Answer

Use GRS (geo-redundant storage) with automated failover

Answer

Use GZRS (geo-zone-redundant storage) with customer-managed failover

Question 7

Which TWO Azure services can be used together to provide a disaster recovery solution for an on-premises SQL Server database with an RPO of 5 minutes and an RTO of 30 minutes? (Select TWO.)

Accepted Answer

Azure SQL Database failover groups. Azure SQL Database failover groups (option A) are correct because they provide automatic geo-replication and a readable secondary endpoint with asynchronous replication that can meet a 5-minute RPO and fast, DNS-based failover well within a 30-minute RTO for a migrated on-premises SQL Server database. Azure SQL Managed Instance failover groups (option C) are also correct because they offer the same auto-failover group capability with near-real-time asynchronous replication and a listener endpoint, which satisfies the 5-minute RPO and 30-minute RTO requirements while preserving near-full SQL Server compatibility for on-premises workloads. Azure Backup for SQL Server (option B) is a backup/restore service whose RPO depends on backup frequency and whose restore times typically exceed 30 minutes, so it cannot guarantee the required RPO/RTO. SQL Server Log Shipping to Azure (option D) has a minimum 15-minute log-shipping interval by default and manual failover, so it cannot meet a 5-minute RPO or the 30-minute RTO. Azure Site Recovery (option E) replicates VMs, not SQL Server databases, and is not the appropriate service for database-level disaster recovery with these RPO/RTO targets.

Answer

Azure Backup for SQL Server

Answer

SQL Server Log Shipping to Azure

Answer

Azure Site Recovery

Question 8

A financial services company runs a critical application on Azure VMs with SQL Server Always On availability groups. The primary region is East US, and the secondary region is West US. The business requires automatic failover with zero data loss in case of a regional disaster. Which configuration should you recommend for the availability group?

Accepted Answer

Use synchronous commit mode with automatic failover. The requirement for automatic failover with zero data loss in a disaster recovery scenario necessitates synchronous commit mode, which ensures that transactions are committed on both the primary and secondary replicas before the primary acknowledges the commit. Automatic failover is only supported with synchronous commit mode when both replicas are in a healthy state, allowing the secondary to automatically become the primary without manual intervention. This configuration meets the business need for zero data loss (RPO=0) and minimal downtime (RTO) during a regional disaster.

Answer

Use synchronous commit mode with manual failover

Answer

Use asynchronous commit mode with automatic failover

Answer

Use asynchronous commit mode with manual failover

Question 9

A company runs a critical SQL Server database on an Azure VM. The database is used by a line-of-business application that requires minimal data loss (RPO of 5 seconds) and fast recovery (RTO of 15 minutes). The VM is in a single region. What should you recommend to meet the RPO and RTO requirements?

Accepted Answer

Migrate the database to Azure SQL Managed Instance and configure a failover group with a secondary in another region.. Azure SQL Managed Instance with a failover group provides automated geo-replication with an RPO of 5 seconds and an RTO of 15 minutes, meeting the critical requirements. The failover group uses a secondary replica in another region, enabling automatic or manual failover with minimal data loss and fast recovery, which is ideal for a line-of-business application with strict RPO/RTO targets.

Answer

Use Azure Storage geo-redundant storage (GRS) for the VM's managed disks.

Answer

Deploy the VM in an Availability Set and use SQL Server Always On Availability Groups.

Answer

Configure Azure Backup for the VM with application-consistent backups every 5 minutes.

Question 10

You are designing a disaster recovery plan for a critical application that runs on Azure VMs. The VMs are in a single region and are backed up daily. The RPO is 1 hour and the RTO is 4 hours. The current backup solution cannot meet the RPO. You need to recommend a solution that meets the requirements with minimal cost. What should you do?

Accepted Answer

Implement Azure Site Recovery with a replication policy of 30 minutes.. Azure Site Recovery (ASR) replicates Azure VMs at a block level, enabling near-synchronous replication with configurable frequency. A 30-minute replication policy meets the 1-hour RPO by ensuring data loss is limited to at most 30 minutes, while also satisfying the 4-hour RTO through automated failover. This is the most cost-effective option because it uses existing VM storage and does not require additional database licensing or increased backup storage costs.

Answer

Configure SQL Server Always On Availability Groups across two Azure regions.

Answer

Increase the backup frequency to every 30 minutes.

Answer

Implement Azure Site Recovery with a replication policy of 15 minutes.

Question 11

A company needs to protect an Azure App Service web app from regional outages. The web app uses Azure SQL Database. They need to ensure that users are automatically redirected to a secondary region if the primary region fails. What should you configure?

Accepted Answer

Deploy the web app in two regions and use Azure Traffic Manager with priority routing.. Azure Traffic Manager with priority routing is a DNS-based traffic load balancer that enables automatic failover to a secondary region. When the primary region's endpoint is unhealthy, Traffic Manager redirects traffic to the secondary region. This meets the requirement for automatic redirection during regional outages. Azure Front Door, while also capable, is not strictly required; Traffic Manager is a simpler and cost-effective solution for this scenario.

Answer

Configure Azure Backup for the web app and restore in a secondary region.

Answer

Deploy the web app in a single region with a Standard Load Balancer and backend pool.

Answer

Deploy the web app in two regions and use Azure Front Door with an origin group and health probes.

Question 12

You have an Azure Storage account that stores critical data. You need to ensure that the data remains accessible if the primary region fails. The solution must minimize data loss and automatically failover. What should you configure?

Accepted Answer

Read-access geo-zone-redundant storage (RA-GZRS).. Read-access geo-zone-redundant storage (RA-GZRS) provides both zone redundancy within the primary region (for resilience to datacenter failures) and geo-redundancy to a secondary region (for resilience to a full regional outage). It also enables automatic failover (Microsoft-managed) and, crucially, read access to the secondary region even before failover occurs, minimizing data loss by allowing continuous reads from the secondary during a disaster.

Answer

Zone-redundant storage (ZRS) with customer-managed failover.

Answer

Locally redundant storage (LRS) with soft delete.

Answer

Geo-redundant storage (GRS) with manual failover.

Question 13

Your company runs a mission-critical application on Azure VMs in a single region. The application requires an RPO of 5 minutes and an RTO of 30 minutes. You plan to use Azure Site Recovery (ASR) to replicate the VMs to a secondary region. The VMs use managed disks. However, during a disaster recovery drill, you discover that the failover takes longer than expected. What is the most likely cause?

Accepted Answer

The VMs have large attached data disks that require significant time to synchronize.. During a disaster recovery drill, Azure Site Recovery (ASR) must synchronize all data from the source managed disks to the target region before failover can complete. Large attached data disks contain significant amounts of data that need to be replicated, and if the initial replication or ongoing synchronization is not fully caught up, the failover process will be delayed while waiting for the final delta sync. This directly impacts the RTO, as the time to complete failover includes the time required to apply the latest changes to the replicated disks.

Answer

The replication policy is set to 30 minutes.

Answer

The Azure Hybrid Benefit is not applied to the VMs.

Answer

The recovery plan includes too many manual steps.

Question 14

Which TWO actions should you take to ensure business continuity for an Azure Functions app that processes messages from an Azure Service Bus queue?

Accepted Answer

Implement the event source pattern to replay messages in case of failure.. Option A is correct because the event source pattern (checkpointing with the Service Bus trigger's peek-lock/complete mechanism) lets the Functions app replay or reprocess messages after a failure, preserving message processing continuity. Option B is correct because enabling geo-replication on the Service Bus namespace replicates the queue and its messages to a secondary region, so the Functions app can continue consuming messages if the primary region fails. Option C is incorrect because a single namespace is a single point of failure and does not provide regional redundancy. Option D is incorrect because deploying the Functions app in a single region leaves it vulnerable to a regional outage, undermining business continuity. Option E is incorrect because Azure Backup does not back up Azure Functions apps or their Service Bus queue messages, so it cannot ensure continuity for this scenario.

Answer

Use a single Service Bus namespace to simplify management.

Answer

Deploy the Functions app in a single region.

Answer

Configure Azure Backup for the Functions app.

Question 15

Which THREE components are required to implement a disaster recovery solution for Azure Virtual Desktop (AVD) using active-passive model?

Accepted Answer

Configure Azure Files geo-replication for the profile share.. Option A is correct because in an active-passive AVD disaster recovery design the FSLogix profile share must be available in the secondary region, and Azure Files geo-replication (geo-redundant storage with a secondary region endpoint) provides that replicated profile data for failover. Option B is correct because Azure File Sync can replicate the FSLogix profile containers from the primary file share to a secondary-region Azure file share or Windows file server, keeping user profiles synchronized for the passive site. Option D is correct because an active-passive model requires a host pool deployed in the secondary region so that session hosts exist and can be started when the primary region fails; the primary host pool alone cannot serve users after a regional outage. Option C is incorrect because deploying the host pool only in the primary region leaves no AVD capacity in the secondary region, defeating the passive failover requirement. Option E is incorrect because Azure Backup protects session host OS/data for restore scenarios but does not provide the regional AVD capacity or profile availability needed for active-passive disaster recovery.

Answer

Deploy AVD host pool in the primary region only.

Answer

Configure Azure Backup for the AVD session hosts.
