AZ-305 Practice Test 25 — 15 Questions

Question 1

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 2

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 Alternatively, SQL Server Stretch Database is outdated; the correct answer is Azure SQL Database Managed Instance failover groups.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 3

You are designing a business continuity solution for a global e-commerce platform that runs on Azure Kubernetes Service (AKS) in multiple regions. The application must remain available even if an entire Azure region fails. The application uses Azure Cosmos DB for its database. You need to ensure that the application can continue to serve traffic with minimal disruption. What should you recommend?

Accepted Answer

Configure Cosmos DB with multi-region writes and deploy AKS clusters in two regions behind Azure Front Door.. Option B (multi-region write Cosmos DB with multi-region AKS) provides active-active architecture with automatic failover. Option A (single-region with backups) has high RTO. Option C (geo-redundant storage) is for data only. Option D (Traffic Manager with passive) has lower availability.

Answer

Use Cosmos DB with geo-redundant storage and deploy a single AKS cluster with Azure Site Recovery.

Answer

Deploy AKS clusters in two regions with Azure Traffic Manager and use Cosmos DB single-region writes with async replication.

Answer

Deploy the application to a single region and use Azure Backup for Cosmos DB to restore in another region.

Question 4

A company stores backup data for Azure VMs in a Recovery Services vault. They need to ensure that the backup data is protected from accidental deletion and remains available even if the entire Azure region fails. What should you configure?

Accepted Answer

Enable soft delete in the vault and use geo-redundant storage (GRS).. Option B (soft delete and geo-redundant storage) provides protection against deletion and region failure. Option A (LRS) does not protect against region failure. Option C (immutable storage) is not available in Recovery Services vaults. Option D (RBAC) does not protect against deletion by authorized users.

Answer

Assign Azure RBAC roles to limit access to the vault.

Answer

Enable immutable storage for the vault.

Answer

Enable locally redundant storage (LRS) for the vault.

Question 5

Which TWO features should you use to meet an RPO of 0 seconds for an Azure SQL Database that is part of a critical application?

Accepted Answer

Failover group with readable secondary.. Option B (active geo-replication with auto-failover group) and Option D (failover group) provide synchronous replication with RPO=0. Option A (backup) has higher RPO. Option C (ASR) not for databases. Option E (auto-failover group) includes active geo-replication.

Answer

Azure Site Recovery for SQL VMs.

Answer

Azure SQL Database backups with short-term retention.

Answer

Auto-failover group with asynchronous replication.

Question 6

A company runs a file server on Azure VMs using Windows Server. The server stores business-critical documents. You need to design a backup strategy that meets a recovery point objective (RPO) of 1 hour and recovery time objective (RTO) of 4 hours. The solution must be cost-effective. Which backup solution should you use?

Accepted Answer

Azure Backup for Azure VMs. Option D is correct because Azure Backup for Azure VMs provides application-consistent backups with a frequency of up to every hour, meeting RPO of 1 hour, and RTO of a few hours for file-level restore. Option A (Azure Site Recovery) is for replication, more costly. Option B (Azure File Sync) syncs files, not backup. Option C (Azure Backup for blobs) is for blobs, not VMs.

Answer

Azure Site Recovery

Answer

Azure Backup for Azure Blobs

Answer

Azure File Sync

Question 7

Which TWO of the following Azure services can be used to enable automatic failover of a web application across Azure regions?

Accepted Answer

Azure Front Door. Options A and B are correct. Azure Front Door provides global load balancing with automatic failover. Azure Traffic Manager can also route traffic based on priority and automatically fail over. Option C (Azure Load Balancer) is regional. Option D (Azure Application Gateway) is regional. Option E (Azure DNS) does not provide health-based failover.

Answer

Azure DNS

Answer

Azure Load Balancer

Answer

Azure Application Gateway

Question 8

Refer to the exhibit. You are deploying an ARM template to configure backup for an Azure Web App. The deployment fails with an error: 'The resource 'Microsoft.Web/sites/config' cannot be nested under a parent resource that is not deployed.' What is the MOST LIKELY cause?

Accepted Answer

The parent web app resource is not defined in the template. Option D is correct because the backup configuration resource is defined as a child resource of the web app, but the parent web app ('Microsoft.Web/sites') is not included in the template. In ARM templates, child resources must be nested under their parent or the parent must be deployed in the same template. Since the web app is not defined, the deployment fails. Option A is wrong because the backup schedule is valid. Option B is wrong because the storage account URL is obtained using reference(), which works if the storage account is deployed or exists. Option C is wrong because the apiVersion is correct for the resource type.

Answer

The storageAccountUrl property uses a reference() that cannot be resolved

Answer

The apiVersion '2022-03-01' is not supported for this resource type

Answer

The backup schedule frequency interval is invalid

Question 9

Which TWO of the following are valid options to achieve high availability for Azure SQL Database? (Choose two.)

Accepted Answer

Deploy a zone-redundant Azure SQL Database. Options B and D are correct. Zone-redundant deployment (B) provides high availability within a region by replicating across availability zones. Active geo-replication (D) provides cross-region high availability and disaster recovery. Option A is wrong because a single database with locally redundant storage offers no high availability. Option C is wrong because Azure SQL Database does not support manual failover to a replica without geo-replication. Option E is wrong because always on availability groups are for SQL Server on VMs, not Azure SQL Database.

Answer

Deploy a single database with locally redundant storage (LRS)

Answer

Configure manual failover to a secondary replica in the same region

Answer

Configure SQL Server Always On availability groups

Question 10

You are designing a business continuity plan for a global e-commerce platform that runs on Azure Kubernetes Service (AKS) in the West US region. The platform uses Azure SQL Database for transactional data and Azure Cache for Redis for session state. The Recovery Time Objective (RTO) for the entire platform is 10 minutes, and the Recovery Point Objective (RPO) is 5 minutes. Which combination of technologies would meet these requirements with the least operational overhead?

Accepted Answer

Deploy AKS clusters in two regions with Azure Front Door; configure Azure SQL Database active geo-replication; enable Azure Cache for Redis geo-replication.. Option A is correct because AKS with Azure Front Door provides global load balancing and can redirect traffic to a secondary region; Azure SQL Database active geo-replication meets the RPO of 5 seconds (less than 5 minutes) and RTO of seconds; Azure Cache for Redis geo-replication meets the RPO and RTO for session state. Option B is wrong because Azure Site Recovery for AKS adds complexity and does not replicate Azure SQL Database or Redis natively. Option C is wrong because Azure Backup for AKS and Azure SQL Database has RPO of hours. Option D is wrong because Cosmos DB is not the current database service, and it would require application changes.

Answer

Back up AKS cluster state and Azure SQL Database using Azure Backup; restore in a secondary region during failover.

Answer

Use Azure Site Recovery to replicate the AKS cluster and Azure SQL Database to a secondary region; use Azure Redis Cache with data persistence.

Answer

Migrate the database to Azure Cosmos DB for multi-region writes; use Traffic Manager for AKS failover.

Question 11

A company wants to protect its Azure Files shares from accidental deletion or ransomware. They need to be able to recover files from up to 30 days ago. What solution should they implement?

Accepted Answer

Enable soft delete for Azure Files shares and configure share snapshots. Option A is correct because Azure Files supports soft delete and file share snapshots (which are part of backup). Soft delete retains deleted files for up to 30 days by default. Option B is wrong because Azure Backup for Azure Files provides backup but not necessarily the 30-day recovery point needed. Option C is wrong because Azure File Sync syncs files but does not provide point-in-time recovery. Option D is wrong because Azure Storage replication options (LRS/GRS) do not protect against accidental deletion at the file level.

Answer

Sync the Azure Files share to an on-premises server using Azure File Sync

Answer

Use Azure Backup for Azure Files with a 30-day retention policy

Answer

Configure geo-redundant storage (GRS) for the storage account

Question 12

Your company runs a critical web application on Azure Virtual Machines in a single region. You need to design a disaster recovery solution that meets a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 1 hour. The solution must be cost-effective for a planned failover test. What should you do?

Accepted Answer

Configure Azure Site Recovery (ASR) with replication to a paired secondary region and perform regular test failovers.. Option C is correct because Azure Site Recovery with replication intervals as low as 30 seconds can meet the RPO of 15 minutes, and with pre-staged resources, the RTO of 1 hour is achievable. It is cost-effective for testing because replication can be paused and test failover uses isolated networks without affecting production. Option A is wrong because Azure Backup's typical RPO is 1 day and RTO is hours. Option B is wrong because Availability Zones protect within a region, not across regions. Option D is wrong because read-only replicas do not provide failover capability for compute.

Answer

Create a read-only replica of the VMs in another region using Azure SQL Database geo-replication.

Answer

Deploy the VMs across two Azure Availability Zones within the same region.

Answer

Use Azure Backup with daily backups to a Recovery Services vault in a paired region.

Question 13

You are designing a disaster recovery plan for an Azure virtual machine running a critical application. The solution must meet an RPO of 1 hour and an RTO of 4 hours. Which TWO actions should you take? (Choose TWO.)

Accepted Answer

Enable Azure Site Recovery for the VM with replication to a secondary region.. Options B and D are correct. Azure Site Recovery can replicate VMs with an RPO as low as 30 seconds and RTO of a few hours. Using a Recovery Services vault with GRS ensures geo-redundancy. Option A is wrong because Azure Backup has a higher RPO. Option C is wrong because Availability Zones do not provide cross-region DR. Option E is wrong because Azure Front Door is for traffic distribution, not VM replication.

Answer

Deploy the VM in an Availability Set and use premium storage.

Answer

Configure Azure Backup with daily snapshots stored in a Recovery Services vault.

Answer

Use Azure Front Door to distribute traffic between the primary and secondary regions.

Question 14

You are designing a disaster recovery solution for a tier-1 application that runs on Azure SQL Managed Instance. The application has a Recovery Time Objective (RTO) of 30 seconds and a Recovery Point Objective (RPO) of 10 seconds. The solution must also support failover during planned maintenance. What should you recommend?

Accepted Answer

Set up a failover group for Azure SQL Managed Instance between two regions with a secondary replica.. Option B is correct because failover groups for Azure SQL Managed Instance provide automatic failover with RPO of 0 (no data loss) and RTO of about 10 seconds, meeting the strict requirements. Option A is wrong because auto-failover groups for SQL Database are different and not for Managed Instance. Option C is wrong because active geo-replication is for SQL Database, not Managed Instance. Option D is wrong because Azure Site Recovery does not replicate SQL Managed Instance natively and cannot meet the low RPO/RTO.

Answer

Configure auto-failover groups with a readable secondary in another region for Azure SQL Database.

Answer

Implement Azure Site Recovery to replicate the SQL Managed Instance to a secondary region.

Answer

Use active geo-replication for Azure SQL Managed Instance with a secondary in another region.

Question 15

You are designing a business continuity solution for a globally distributed SaaS application that uses Azure Cosmos DB for its operational store. The application must survive a complete regional outage with zero data loss and automatic failover. What should you use?

Accepted Answer

Configure Cosmos DB with a single write region, strong consistency, and enable automatic failover to a secondary region.. Option D is correct because Cosmos DB multi-region writes with the strong consistency mode in a single-region write configuration ensures no data loss (RPO=0) and automatic failover via the service-managed failover policy. Option A is wrong because multi-region writes with eventual consistency can result in data loss. Option B is wrong because a single-region write with eventual consistency has an RPO > 0. Option C is wrong because Azure SQL Database geo-replication is not the right service.

Answer

Configure a single write region in Cosmos DB with eventual consistency and manual failover.

Answer

Enable multi-region writes in Cosmos DB with eventual consistency and automatic failover.

Answer

Use Azure SQL Database with active geo-replication and automatic failover.
