AZ-305 Design business continuity solutions Practice Test 9 — 15 Questions

Question 1

You are designing a backup strategy for Azure VMs that host a file server. The backup must support daily backups with a retention of 30 days, and the ability to restore individual files quickly. The solution must minimize backup storage costs. What backup policy should you configure?

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

Accepted Answer

Use Azure Backup with daily backup, retention of 30 days, and enable instant restore snapshot for file-level recovery.. Option B is correct because Azure Backup for Azure VMs uses instant restore snapshots to provide fast file-level recovery. The backup policy defines the daily backup schedule, 30-day retention, and instant restore snapshot retention. Storage redundancy (LRS/GRS) is configured at the Recovery Services vault level, not in the backup policy; to minimize costs, select LRS at the vault level separately. Option A is incorrect because it treats LRS as part of the backup policy and does not address the file-level recovery requirement. Option C uses GRS, which increases cost unnecessarily, and option D uses weekly backups, which violates the daily backup requirement.

Answer

Use Azure Backup with daily backup, retention of 30 days, and use locally redundant storage (LRS) for backup data.

Answer

Use Azure Backup with daily backup, retention of 30 days, and use geo-redundant storage (GRS) for backup data.

Answer

Use Azure Backup with weekly backup, retention of 30 days, and use geo-redundant storage (GRS) for backup data.

Question 2

You are designing a backup strategy for Azure VMs that host a file server. The backup must support daily backups with a retention of 30 days, and the ability to restore individual files quickly. The solution must minimize backup storage costs. What backup policy should you configure?

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

Accepted Answer

Use Azure Backup for Azure Files with soft delete enabled.. Azure Backup for Azure Files provides snapshot-based backups that support point-in-time restoration, and when combined with soft delete, it protects against accidental deletion by retaining deleted data for a configurable retention period (default 14 days). This meets all stated requirements: snapshot backups, point-in-time restore, and deletion protection.

Answer

Use Azure File Sync with cloud tiering.

Answer

Use Azure Storage account geo-redundant storage (GRS) with versioning.

Answer

Use Azure Backup for Azure Files without soft delete.

Question 3

A company has a disaster recovery plan that requires testing failover of Azure VMs regularly without impacting the production environment. Which feature of Azure Site Recovery should they use?

Accepted Answer

Test failover. Test failover (Option B) is the correct feature for validating disaster recovery readiness without affecting the production environment. Azure Site Recovery's test failover creates an isolated copy of the replicated VMs in a separate virtual network, allowing you to run validation exercises, perform application testing, and verify recovery plans without any impact on the production VMs or ongoing replication. This ensures that the failover process works correctly while maintaining production continuity.

Answer

Planned failover

Answer

Unplanned failover

Answer

Failback

Question 4

Which TWO actions should you take to ensure business continuity for an Azure App Service web app that uses Azure SQL Database? (Choose two.)

Accepted Answer

Configure Azure SQL Database failover groups with automatic failover.. Option A is correct because Azure SQL Database failover groups provide automatic geo-failover of the database to a secondary region, ensuring the data tier remains available during a regional outage without manual intervention. Option C is correct because deploying the App Service app in two regions, each with its own App Service plan, and using Azure Traffic Manager for global traffic distribution provides a multi-region, highly available web tier that can route users to a healthy region if one fails. Option B is not correct because auto-healing and retry logic only address transient application-level faults, not regional or infrastructure-level failures required for business continuity. Option D is not correct because Azure Front Door with a single App Service instance still leaves a single point of failure in one region. Option E is not correct because Azure Backup and geo-restore are for data recovery/restore scenarios, not continuous availability or automatic failover.

Answer

Enable auto-healing in the App Service and modify the application code to handle retries.

Answer

Use Azure Front Door with a single App Service instance.

Answer

Configure Azure Backup for the App Service and enable geo-restore.

Question 5

Which THREE components are required to implement a disaster recovery solution for Azure SQL Database using failover groups? (Choose three.)

Accepted Answer

A failover group that includes both servers. A failover group is the core orchestration component that manages the replication and automatic or manual failover of multiple databases between a primary and secondary Azure SQL Database server. It requires both a primary server in one region and a secondary server in another region to be included in the group, enabling a coordinated disaster recovery plan with a defined failover policy.

Answer

Zone-redundant configuration on the primary database

Answer

Active geo-replication configured on the primary database

Question 6

Which TWO Azure services can be used to automatically redirect traffic to an alternate region in the event of a regional outage? (Choose two.)

Accepted Answer

Azure Traffic Manager. Azure Traffic Manager (C) is a DNS-based global traffic load balancer that can route users to endpoints in different regions and, with priority routing plus endpoint monitoring, automatically fail over to an alternate region when the primary region's endpoint becomes unhealthy. Azure Front Door (E) is a global Layer 7 entry point that uses anycast, health probes, and origin groups to detect a regional outage and automatically redirect traffic to a healthy origin in another region. Azure Application Gateway (A) is a regional Layer 7 load balancer, so it can distribute traffic only among backends within its own region and cannot by itself redirect across regions during a regional outage. Azure Load Balancer (B) is a regional Layer 4 load balancer scoped to a single region and has no global failover capability. Azure DNS (D) is a general-purpose authoritative DNS hosting service; it does not provide built-in health probing or automatic regional failover routing on its own.

Answer

Azure Application Gateway

Answer

Azure Load Balancer

Answer

Azure DNS

Question 7

You are reviewing a recovery plan for Azure Site Recovery. The exhibit shows a snippet of the recovery plan configuration. What is the purpose of the script action defined in the exhibit?

Accepted Answer

To run a custom script on the recovered VMs after they boot up during test and unplanned failover.. The script action in an Azure Site Recovery recovery plan is configured to run after the VMs have booted up, allowing custom tasks such as installing software, modifying configurations, or verifying connectivity. This is supported during both test failover and unplanned failover, as the script executes post-boot on the recovered VMs.

Answer

To run a script before the VMs shut down during failover.

Answer

To update the Azure DNS records after failover.

Answer

To run a script only during planned failover from the primary to the recovery region.

Question 8

You are reviewing a PowerShell script for Azure SQL Database. The exhibit shows the script that sets backup retention. What is the effect of running this script?

Accepted Answer

It sets the short-term backup retention to 7 days, enabling point-in-time restore within that period.. The script uses the `Set-AzSqlDatabaseBackupShortTermRetentionPolicy` cmdlet with `-RetentionDays 7`, which configures the short-term backup retention period for point-in-time restore (PITR) to 7 days. This allows restoring the database to any point within the last 7 days, as automated backups are retained for that duration.

Answer

It enables geo-redundant backups for the database.

Answer

It sets the long-term retention (LTR) backup policy to 7 days.

Answer

It increases the backup retention from 7 to 35 days.

Question 9

You are reviewing a Bicep template that deploys two App Service Environments (ASE) and an Azure Traffic Manager profile. The exhibit shows the template snippet. What is the expected behavior when the primary ASE becomes unhealthy?

Accepted Answer

Traffic is automatically routed to the secondary ASE with priority 2.. Azure Traffic Manager uses priority routing, which directs all traffic to the primary endpoint (priority 1) as long as it is healthy. When the primary ASE becomes unhealthy, Traffic Manager automatically fails over to the next priority endpoint (priority 2), ensuring continuous availability without manual intervention.

Answer

Traffic is stopped until an administrator updates the DNS manually.

Answer

Traffic is load-balanced between both ASEs based on performance.

Answer

Traffic continues to be sent to the primary ASE because priority routing only uses the primary.

Question 10

A company runs a critical web application on Azure VMs in two availability zones. They need to ensure the application remains available during a regional outage with an RPO of 5 minutes and an RTO of 15 minutes. What should they implement?

Accepted Answer

Azure Site Recovery. Azure Site Recovery (ASR) is the correct choice because it provides automated replication of Azure VMs from one region to another, enabling failover during a regional outage. With continuous replication, ASR can achieve an RPO of as low as 30 seconds (well within the 5-minute requirement) and, when combined with a well-tested recovery plan, can meet the 15-minute RTO by orchestrating the startup of replicated VMs in the secondary region.

Answer

Azure Backup

Answer

Azure Traffic Manager

Answer

Azure Front Door

Question 11

A financial services company runs a critical SQL Server database on Azure VMs. They require a failover solution that provides automatic detection of database health issues and automatically fails over to a secondary replica in another Azure region with no data loss and sub-minute RPO. What should they use?

Accepted Answer

SQL Server Always On Availability Groups with automatic failover. SQL Server Always On Availability Groups with automatic failover is the correct choice because it supports synchronous data replication between primary and secondary replicas, ensuring zero data loss (RPO=0) and sub-minute RPO. Automatic failover requires a quorum-based health detection mechanism (using Windows Server Failover Clustering) that monitors database health and triggers failover to a secondary replica in another Azure region without manual intervention, meeting the strict RPO and automatic failover requirements.

Answer

Azure SQL Database geo-replication

Answer

Azure SQL Managed Instance failover groups

Answer

Azure Backup for SQL Server

Question 12

A company runs a stateless web application on multiple Azure VMs behind a load balancer. They want to ensure that if a VM fails, traffic is automatically redirected to healthy VMs. Which Azure service provides this functionality with health probes?

Accepted Answer

Azure Load Balancer. Azure Load Balancer (Option D) is the correct choice because it is designed to distribute traffic across multiple VMs in the same region and uses health probes (TCP or HTTP) to monitor the health of each backend VM. If a probe fails, the load balancer automatically stops sending new traffic to that VM and redirects it to the remaining healthy instances, ensuring high availability for the stateless web application.

Answer

Azure Traffic Manager

Answer

Azure Front Door

Answer

Azure Application Gateway

Question 13

A company uses Azure SQL Database for a critical OLTP workload. They need a disaster recovery solution that automatically fails over to a secondary region with an RPO of 5 seconds and an RTO of 1 hour. What should they implement?

Accepted Answer

Azure SQL Database auto-failover groups. Auto-failover groups in Azure SQL Database provide automatic failover across regions, leveraging active geo-replication under the hood. This combination achieves an RPO of up to 5 seconds (from active geo-replication) and an RTO of 1 hour (from the auto-failover group). Active geo-replication alone does not automate failover, which is required for the disaster recovery solution. Zone-redundant configuration protects only within a region, not cross-region. Managed Instance failover groups are for Azure SQL Managed Instance, not for Azure SQL Database, and have different RPO/RTO characteristics.

Answer

Azure SQL Database zone-redundant configuration

Answer

Azure SQL Database active geo-replication

Answer

Azure SQL Managed Instance failover groups

Question 14

A company runs a critical SAP HANA database on an Azure large instance. They need a disaster recovery solution that provides automatic failover to a secondary region with an RPO of 15 minutes and RTO of 30 minutes. The solution must not require manual intervention to start replication. What should they use?

Accepted Answer

SAP HANA System Replication with HANA Pacemaker. SAP HANA System Replication with HANA Pacemaker is the correct choice because it provides automatic, synchronous or asynchronous replication of SAP HANA data to a secondary region, meeting the RPO of 15 minutes and RTO of 30 minutes. HANA Pacemaker handles automatic failover without manual intervention, ensuring the database is promoted to primary in the disaster recovery region within the required timeframes. This solution is specifically designed for SAP HANA on Azure large instances, offering native integration and support for the required recovery objectives.

Question 15

A company uses Azure Kubernetes Service (AKS) to run a containerized microservices application. They need a disaster recovery solution that can automatically fail over to a secondary region if the primary region fails. The solution must minimize data loss for stateful workloads. What should they implement?

Accepted Answer

Azure Site Recovery. Azure Site Recovery (ASR) is the correct choice because it provides orchestrated replication and failover for Azure VMs and physical workloads, including stateful containers running on AKS. ASR can replicate persistent volumes and application data to a secondary region, enabling automated failover with minimal data loss by using crash-consistent or app-consistent recovery points.

Answer

Azure Backup for AKS

Answer

Azure Front Door

Answer

Azure Traffic Manager
