AZ-305 Design business continuity solutions Practice Test 8 — 15 Questions

Question 1

A company runs an application on Azure VMs that uses Azure SQL Database. They need a disaster recovery solution that ensures the application can fail over to a secondary region with minimal data loss. The solution must include automatic failover for the database and manual failover for the VMs. Which TWO Azure services should they use? (Choose two.)

Accepted Answer

Azure SQL Database auto-failover groups. Options B and D are correct. Azure SQL Database auto-failover groups provide automatic failover for the database. Azure Site Recovery replicates the VMs to the secondary region and allows manual failover. Option A is wrong because Azure SQL active geo-replication does not automatically failover; it requires manual action. Option C is wrong because Azure Traffic Manager is for routing, not VM replication. Option E is wrong because Azure Front Door is for global load balancing.

Answer

Azure Traffic Manager

Answer

Azure Front Door

Answer

Azure SQL Database active geo-replication

Question 2

Refer to the exhibit. An administrator reviews the backup status of a VM. The last backup failed. What is the most likely cause?

Accepted Answer

The VM was deallocated at the time of backup.. Option C is correct because the last backup failure could be due to the VM being deallocated at the time of backup. Azure Backup cannot back up VMs that are in a deallocated state. Option A is wrong because the backup policy is referenced by policyId, so it exists. Option B is wrong because the sourceResourceId is present and valid. Option D is wrong because the vault is not shown to be in a different region; besides, cross-region backup is supported.

Answer

The Recovery Services vault is in a different region.

Answer

The backup policy does not exist.

Answer

The source resource ID is missing.

Question 3

A company runs a critical application on Azure VMs. They need to ensure that if an entire Azure region fails, the application can be recovered in another region with minimal data loss. They have a recovery point objective (RPO) of 1 hour and a recovery time objective (RTO) of 4 hours. What should they implement?

Accepted Answer

Azure Site Recovery. Option A is correct because Azure Site Recovery provides VM replication to a secondary region with an RPO of as low as 5 minutes and RTO of a few hours, meeting the 1-hour RPO and 4-hour RTO. Option B is wrong because Azure Backup has an RPO of at least 12 hours. Option C is wrong because Azure Traffic Manager does not replicate data. Option D is wrong because Azure Front Door is for global load balancing, not VM replication.

Answer

Azure Traffic Manager

Answer

Azure Front Door

Answer

Azure Backup

Question 4

Your company runs a critical e-commerce application on Azure Virtual Machines (VMs) in a single region. You need to design a disaster recovery (DR) solution that meets a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour for the application tier. The application uses Azure SQL Database (single database). Which combination of Azure services should you recommend to meet the RPO and RTO?

Accepted Answer

Use Azure Site Recovery for VM replication to a secondary region and Azure SQL Database active geo-replication. Option B is correct because Azure Site Recovery can replicate VMs to a secondary region with an RPO of 15 minutes and RTO of 1 hour for the application tier. Azure SQL Database active geo-replication provides an RPO of 5 seconds and RTO of 1 hour. Option A is wrong because Azure Backup has a higher RPO (typically 12 hours for VMs). Option C is wrong because read-scale replicas do not support failover. Option D is wrong because Azure Front Door is for global load balancing, not DR replication.

Answer

Use Azure Site Recovery for VMs and Azure SQL Database read-scale replicas

Answer

Use Azure Backup for VM replication and Azure SQL Database auto-failover groups

Answer

Use Azure Front Door with regional load balancing and Azure SQL Database geo-restore

Question 5

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. Option D is correct because object replication with a minimum Replication Time Objective (RTO) of 15 minutes meets the RPO requirement, and a secondary read-access region meets the RTO of 1 hour. Option A is wrong because RA-GRS has an RPO of 15 minutes but failover is manual and may take longer. Option B is wrong because GZRS with manual failover may exceed RTO. Option C is wrong because geo-redundant storage (GRS) does not provide read access in the secondary region.

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 6

Which TWO Azure services can be used to provide cross-region disaster recovery for Azure App Service web applications with a custom domain? (Select TWO.)

Accepted Answer

Azure Front Door. Options A and B are correct. Azure Traffic Manager can route traffic to a secondary region App Service in case of primary region failure. Azure Front Door provides global load balancing and failover. Options C, D, and E are wrong: Azure Application Gateway is regional, Azure DNS does not provide traffic routing, and Azure CDN is for content caching, not failover.

Answer

Azure DNS

Answer

Azure CDN

Answer

Azure Application Gateway

Question 7

Refer to the exhibit. You deploy this ARM template to create a storage account in the West US region. The business continuity requirement states that if the primary region becomes unavailable, the storage account must be readable within 1 hour. What is the most important limitation of this configuration?

Accepted Answer

The storage account does not support read access in the secondary region, so manual failover is required, which may exceed the 1-hour RTO. Option A is correct because GRS (geo-redundant storage) does not provide read access to the secondary region; failover is manual and may take longer than 1 hour. Option B is wrong because the access tier does not affect DR. Option C is wrong because HTTPS enforcement does not affect DR. Option D is wrong because GRS replicates data to a paired region, but without read access.

Answer

The storage account uses GRS, which replicates data only to a secondary region within the same geography, not to a different region

Answer

The storage account only supports HTTPS traffic, which blocks replication

Answer

The storage account is configured with the Hot access tier, which prevents failover

Question 8

Your company has a hybrid identity solution with Microsoft Entra ID Connect syncing on-premises Active Directory to Microsoft Entra ID. You need to design a business continuity solution for the identity service in case of an on-premises outage. The solution must allow users to authenticate and access cloud applications even if the on-premises domain controllers are unavailable. Which feature should you enable?

Accepted Answer

Password hash synchronization. Option C is correct because Microsoft Entra Connect sync provides password hash synchronization, which allows cloud authentication even if on-premises DCs are down. Option A is wrong because pass-through authentication requires on-premises agents. Option B is wrong because federation requires on-premises AD FS. Option D is wrong because Seamless SSO relies on on-premises authentication.

Answer

Federation with AD FS in a secondary on-premises site

Answer

Seamless Single Sign-On

Answer

Pass-through authentication with an agent in a secondary on-premises site

Question 9

Which THREE Azure services can be used to implement a disaster recovery plan for Azure Virtual Desktop (AVD) that meets an RTO of 2 hours and an RPO of 30 minutes? (Select THREE.)

Accepted Answer

Azure Site Recovery. Options A, C, and E are correct. Azure Site Recovery can replicate AVD session host VMs. Azure Files can store FSLogix profiles in a geo-redundant storage account. Azure Backup can back up the AVD configuration and user data. Options B and D are wrong: Azure Migrate is for migration, not DR; Azure Database for MySQL is not typically part of AVD.

Answer

Azure Database for MySQL

Answer

Azure Migrate

Question 10

Refer to the exhibit. This ARM template configures backup for an Azure App Service web app. The backup is scheduled daily. What is the primary limitation of this backup strategy in meeting a disaster recovery RPO of 4 hours?

Accepted Answer

The backup frequency is 1 day, resulting in an RPO of up to 24 hours. Option B is correct because the backup schedule is daily, leading to an RPO of up to 24 hours, which exceeds the 4-hour requirement. Option A is wrong because storage account location does not affect RPO. Option C is wrong because retention period does not affect RPO. Option D is wrong because the backup includes the app content, but the frequency is the issue.

Answer

The backup storage account is in the same region as the web app

Answer

The retention period of 30 days is too short

Answer

The backup does not include the web app configuration

Question 11

You are designing a business continuity solution for a mission-critical Azure Kubernetes Service (AKS) cluster. The cluster hosts a stateful application that uses Azure Disks for persistent volumes. You need to ensure that the application can be recovered in a secondary region within 1 hour of a regional failure. What should you use to replicate the persistent volumes?

Accepted Answer

Azure Site Recovery with replication of the AKS node VMs and attached disks. Option A is correct because Azure Site Recovery can replicate Azure Disks (via VM replication) to a secondary region. Velero can back up AKS resources, but for stateful disks, ASR is more appropriate for DR. Option B is wrong because Azure Backup is for file/VM backup, not disk replication. Option C is wrong because Azure File Sync is for file shares, not disks. Option D is wrong because Azure Disk Backup is for backup, not replication for DR.

Answer

Azure Disk Backup with geo-redundant storage

Answer

Azure Backup with disk snapshot policies

Answer

Azure File Sync to replicate the disk content

Question 12

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. Options A and D are correct. Azure SQL Managed Instance has a failover group feature that can replicate the database to a secondary region with automatic failover, meeting RPO/RTO. Alternatively, SQL Server Stretch Database is outdated; the correct answer is Azure SQL Database Managed Instance failover groups. Option B is wrong because Azure Site Recovery replicates VMs, not databases directly. Option C is wrong because Azure Backup has a higher RPO. Option E is wrong because Log Shipping is an on-premises feature.

Answer

Azure Backup for SQL Server

Answer

SQL Server Log Shipping to Azure

Answer

Azure Site Recovery

Question 13

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. Option D is correct because synchronous commit mode with automatic failover ensures zero data loss and automatic failover. Option A is wrong because asynchronous commit can have data loss. Option B is wrong because manual failover does not meet automatic requirement. Option C is wrong because asynchronous commit with automatic failover can cause data loss.

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 14

Refer to the exhibit. You are reviewing an Azure Site Recovery replicated item for a VM. The replication health is Normal, and the last recovery point is at 10:30 AM. The primary region experiences a failure at 10:35 AM. You initiate a failover at 10:40 AM. What is the maximum potential data loss?

Accepted Answer

5 minutes of data. Option A is correct because the last recovery point is at 10:30 AM, and the failure occurred at 10:35 AM. The data loss is up to 5 minutes of data (between 10:30 and 10:35). Option B is wrong because the RPO is defined by the policy, but the actual loss is based on the last recovery point. Options C and D are incorrect.

Answer

15 minutes of data

Answer

0 minutes of data

Answer

10 minutes of data

Question 15

Your company uses Azure Backup to protect on-premises file servers and Azure VMs. The compliance team requires that backup data be stored in a secondary region to protect against regional disasters. Which Azure Backup feature should you enable?

Accepted Answer

Enable geo-redundant storage (GRS) for the Recovery Services vault. Option B is correct because Azure Backup allows configuring a Recovery Services vault with geo-redundant storage (GRS) to replicate backup data to a paired region. Option A is wrong because Recovery Services vault is the container, not the replication feature. Option C is wrong because Back up to a secondary region is not supported directly. Option D is wrong because Azure Site Recovery is for replication, not backup.

Answer

Use Azure Site Recovery to replicate the backup data

Answer

Configure backup policies to back up directly to the secondary region

Answer

Use a Recovery Services vault in the secondary region
