AZ-305 Practice Test 22 — 15 Questions

Question 1

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. Option C is correct because AKS with Azure Disks using zone-redundant storage (ZRS) provides replication across zones within a region, but for cross-region DR, they need to pair with Azure Site Recovery or use a multi-region AKS with Velero for backup and restore. However, among the options, Azure Site Recovery is the only one that provides cross-region failover for AKS with persistent volumes. Option A is wrong because Azure Traffic Manager only routes traffic, does not replicate data. Option B is wrong because Azure Front Door is for global load balancing, not DR. Option D is wrong because Azure Backup for AKS is backup-only, not failover.

Answer

Azure Backup for AKS

Answer

Azure Front Door

Answer

Azure Traffic Manager

Question 2

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 3

Which THREE of the following are best practices for designing a business continuity solution using Azure Site Recovery? (Select THREE.)

Accepted Answer

Perform test failovers regularly to validate the recovery plan. Options A, C, and D are correct. Testing failover regularly validates the DR plan. Using a recovery plan orchestrates failover of multi-tier applications. Enabling replication for all critical VMs ensures protection. Option B is wrong because using a single target region for all VMs can cause resource contention; multiple target regions may be needed. Option E is wrong because manual failover should be used only if automatic fails.

Answer

Configure automatic failover for all VMs without manual intervention

Answer

Use a single target region for all VMs to simplify management

Question 4

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 Front Door with an origin group and health probes.. Option A (Azure Front Door with origin groups and health probes) provides automatic failover. Option B (Traffic Manager) does not integrate with App Service health. Option C (App Service backup) does not provide automatic failover. Option D (Standard Load Balancer) is not regional.

Answer

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

Answer

Deploy the web app in two regions and use Azure Traffic Manager with priority routing.

Answer

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

Question 5

A multinational company runs a mission-critical application on Azure VMs in the West US region. The application uses Azure SQL Database (Business Critical tier) and Azure Cache for Redis. The company needs to ensure the application can fail over to a secondary region within 5 minutes during a regional outage. The design must minimize data loss. Which solution should you recommend?

Accepted Answer

Deploy VMs in an Azure Site Recovery recovery plan to East US, use Azure SQL Database active geo-replication with auto-failover group, and use Azure Cache for Redis with geo-replication enabled.. Option C is correct because it uses Azure SQL Database active geo-replication with a failover group for automatic failover (RPO ≤ 5 seconds, RTO ≤ 1 minute) and Azure Cache for Redis with geo-replication for cross-region replication. Option A has longer RTO for SQL failover. Option B uses Azure SQL Database with geo-restore which has RPO of 1 hour. Option D uses cache replication that is not available in Standard tier.

Answer

Deploy VMs across Azure availability zones in West US, use Azure SQL Database geo-restore to East US, and deploy a second Azure Cache for Redis instance in East US.

Answer

Deploy VMs in an availability set in West US, use Azure Site Recovery to replicate to East US, and configure Azure SQL Database failover group with manual failover.

Answer

Deploy VMs in an Azure Site Recovery recovery plan to East US, use Azure SQL Database active geo-replication with auto-failover group, and deploy Azure Cache for Redis Standard tier in East US.

Question 6

Which THREE of the following are required components for a disaster recovery solution using Azure Site Recovery for on-premises Hyper-V VMs?

Accepted Answer

A Recovery Services vault in the target Azure region.. Options A, B, and D are correct. Azure Site Recovery requires a Recovery Services vault, a replication policy, and the Azure Site Recovery Provider installed on Hyper-V hosts. Option C (Azure Backup Server) is not required; Site Recovery uses its own replication mechanism. Option E (ExpressRoute) is optional.

Answer

Azure Backup Server installed on-premises.

Answer

An ExpressRoute connection from on-premises to Azure.

Question 7

A company runs a critical application on Azure VMs. They want to ensure high availability within a region using Azure Site Recovery. What is the correct configuration?

Accepted Answer

Deploy VMs across multiple availability zones and use a load balancer. Option B is correct because Azure Site Recovery is designed for disaster recovery across regions, not within a region. For intra-region high availability, availability zones should be used. Option A is wrong because Site Recovery does not support intra-region replication to availability zones directly. Option C is wrong because Site Recovery cannot replicate across availability sets. Option D is wrong because Site Recovery can replicate across zones but is not the best practice for intra-region HA.

Answer

Configure Azure Site Recovery to replicate VMs to a paired region

Answer

Use Azure Site Recovery to replicate VMs across availability sets

Answer

Configure Azure Site Recovery to replicate VMs to different availability zones within the same 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 sets the short-term backup retention policy to 7 days for the database 'mydb'. This means point-in-time restore (PITR) backups are retained for 7 days. Option A is incorrect because it says 14 days. Option D is incorrect because it only affects short-term retention.

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

Refer to the exhibit. An administrator runs the PowerShell script to enable replication for a VM. The script fails with an error that the VM is not found. What is the most likely cause?

Accepted Answer

The Azure PowerShell context is not set to the subscription that contains the VM.. Option A is correct because the Get-AzVM cmdlet is run against the current Azure context, which might be set to the DR subscription, but the VM is in the PROD-RG in the production subscription. The script does not switch the context to the production subscription, so the VM is not found. Option B is wrong because the vault is found (Get-AzRecoveryServicesVault succeeds). Option C is wrong because the fabric and protection container are retrieved successfully. Option D is wrong because the policy is retrieved successfully.

Answer

The Recovery Services vault does not exist.

Answer

The protection container is not available.

Answer

The replication policy is not valid.

Question 10

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 11

A company runs a web application on Azure App Service with a Standard tier plan. The application uses an Azure SQL Database (DTU-based) for storage. The business requires that the application remain available in the event of a single Azure region outage. Which solution meets the requirement with the least administrative effort?

Accepted Answer

Deploy an additional App Service in a secondary region and use Azure SQL Database active geo-replication. Option A is correct because App Service deployment slots in a secondary region combined with Azure SQL Database geo-replication provide a low-effort DR solution. Option B is wrong because App Service Environment is more complex and costly. Option C is wrong because Azure Front Door is for global load balancing, not DR. Option D is wrong because Azure Backup does not provide availability during an outage.

Answer

Use an App Service Environment (ASE) in a single region with App Service plans in multiple availability zones

Answer

Use Azure Front Door to route traffic to a secondary App Service in the same region

Answer

Configure Azure Backup for the App Service and SQL Database

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).. Option C (RA-GZRS) provides read access to secondary region and automatic failover if Microsoft initiates. Option A (LRS) no failover. Option B (GRS) failover but no read access. Option D (ZRS) same region.

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 web application on Azure App Service (Standard tier) in a single region. You need to design a disaster recovery solution that can fail over to another region within 30 minutes. The application uses Azure SQL Database (General Purpose tier) and Azure Blob Storage. What should you implement?

Accepted Answer

Configure App Service backup to a secondary region, use Azure SQL Database active geo-replication with auto-failover group, and use geo-redundant storage (GRS) for Blob Storage.. Option B is correct because App Service backup/restore to a secondary region, Azure SQL Database active geo-replication with failover group, and Azure Storage geo-redundant storage (GRS) together meet the RTO of 30 minutes and provide data protection. Option A uses geo-restore for SQL which has longer RPO. Option C uses read-only failover which may not allow writes. Option D uses traffic manager but does not address database failover.

Answer

Use Azure Traffic Manager with priority routing to a second App Service instance, use Azure SQL Database backup to a secondary region, and use Azure Storage zone-redundant storage (ZRS).

Answer

Configure App Service auto-scaling, use Azure SQL Database geo-replication with readable secondary, and use Azure Storage read-access geo-redundant storage (RA-GRS).

Answer

Configure App Service deployment slots, use Azure SQL Database geo-restore, and use Azure Storage locally-redundant storage (LRS).

Question 14

A company uses Azure Cosmos DB with a single write region. They need to ensure business continuity with an RPO of 5 seconds and RTO of 1 minute in case of a regional outage. What configuration should they use?

Accepted Answer

Enable multi-region writes with automatic failover. Option C is correct because Cosmos DB multi-region writes with automatic failover provides the lowest RPO and RTO. With multiple write regions, if one region fails, the other region continues to accept writes with no data loss. Option A is wrong because single-region writes with automatic failover has higher RPO (up to 15 minutes). Option B is wrong because manual failover has higher RTO. Option D is wrong because availability zones protect within a region, not cross-region.

Answer

Enable automatic failover from a single write region to a read region

Answer

Deploy Cosmos DB in an availability zone-enabled region

Answer

Use manual failover to a secondary read region

Question 15

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.. The Traffic Manager profile uses priority routing with primary endpoint priority 1 and secondary priority 2. When the primary endpoint is unhealthy, Traffic Manager automatically routes traffic to the secondary endpoint. Option A is incorrect because it says primary continues. Option C is incorrect because priority routing does not distribute traffic. Option D is incorrect because it mentions 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.
