AZ-305 Practice Test 43 — 15 Questions

Question 1

A company runs several Azure virtual machines (VMs) that host SQL Server databases. The databases are stored on data disks attached to the VMs. The company needs to back up the databases and VMs separately. They require application-consistent backups for SQL Server to ensure transactional integrity. Additionally, they need to retain backups for up to 7 years to meet compliance requirements. The solution must minimize administrative overhead and support long-term retention of database backups. Which Azure service or feature should they use for the database backups?

Accepted Answer

Azure Backup for SQL Server in Azure VMs. Azure Backup for SQL Server in Azure VMs is the correct choice because it provides native, application-consistent backups specifically for SQL Server databases running on Azure VMs. It integrates directly with SQL Server VSS writer to ensure transactional integrity, supports long-term retention up to 10 years (exceeding the 7-year requirement), and minimizes administrative overhead by automating backup scheduling, retention management, and point-in-time restore. This service is purpose-built for SQL Server database backups, separate from VM-level backups.

Azure Backup for Azure VMs with application-consistent snapshots

Answer

Azure Site Recovery

Answer

Azure Files

Question 2

A SaaS company uses Azure SQL Database for a multi-tenant application. They have 80 tenant databases, each with varying and unpredictable usage patterns. The company wants to optimize costs without sacrificing performance and wants the ability to easily add new tenant databases without over-provisioning. Which deployment option should they use?

Accepted Answer

Azure SQL Database elastic pool. Azure SQL Database elastic pool is the correct choice because it allows multiple tenant databases to share a fixed set of resources (DTUs or vCores), automatically absorbing the unpredictable usage spikes of individual tenants without over-provisioning. This model optimizes cost by paying for the pooled resources rather than each database's peak capacity, and new tenant databases can be added seamlessly to the pool without upfront resource allocation.

Answer

Single Azure SQL Database per tenant

Answer

Azure SQL Managed Instance

Answer

Azure SQL Database Hyperscale

Question 3

A company uses Azure Site Recovery to replicate critical Azure virtual machines (VMs) to a secondary Azure region for disaster recovery. The VMs use managed disks and are part of a multi-tier application. After a failover, the recovery VMs must be automatically placed into a specific availability set to maintain the application architecture. How should the administrator configure this in Azure Site Recovery?

Accepted Answer

Configure the target availability set in the VM replication settings in the Recovery Services vault. Option A is correct because Azure Site Recovery (ASR) allows you to configure the target availability set directly in the replication settings for each VM. When you enable replication for a VM, under the 'Target availability set' setting, you can select an existing availability set in the target region. ASR will then automatically place the recovered VM into that availability set during failover, ensuring the multi-tier application architecture is maintained without manual intervention.

Answer

Create a recovery plan and add a manual step or script to move VMs to the availability set after failover

Answer

Convert the managed disks to unmanaged disks for replication, then specify the availability set

Answer

Azure Site Recovery does not support placing VMs into an availability set in the target region

Question 4

Drag and drop the steps to implement Azure Backup for an Azure virtual machine into the correct order.

Question 5

A company runs a critical line-of-business application on 10 Azure VMs. They need a disaster recovery solution that replicates the VMs to a secondary region with a recovery point objective (RPO) of 30 minutes and a recovery time objective (RTO) of 1 hour. The solution must support non-disruptive testing of failover for quarterly compliance drills. Which Azure service should they use?

Accepted Answer

Azure Site Recovery. Azure Site Recovery (ASR) orchestrates replication, failover, and failback of Azure VMs to a secondary region, meeting the RPO of 30 minutes (continuous replication with 30-second RPO) and RTO of 1 hour (orchestrated recovery). It supports non-disruptive test failovers via isolated networks, which is essential for quarterly compliance drills without impacting production.

Question 6

A company runs a critical application on Azure VMs in a single region. They need to ensure business continuity with an RPO of 1 hour and RTO of 4 hours. The application has dependencies on virtual networks, storage accounts, and other Azure resources. They want to use Azure Backup as the primary disaster recovery tool and must be able to restore the entire application in a secondary region if the primary region fails. Which backup strategy should they recommend?

Accepted Answer

Azure Backup for VMs with hourly backups and cross-region restore. Option C is correct because Azure Backup for VMs supports hourly backups (up to every 4 hours for VM backups, but with application-consistent snapshots and cross-region restore, you can achieve an RPO of 1 hour by combining frequent backups with the ability to restore in a secondary region. The cross-region restore feature allows you to restore VMs and their dependencies (VNet, storage accounts) to a paired secondary region, meeting the RTO of 4 hours when using Azure Backup's restore capabilities.

Question 8

A company runs a critical line-of-business application on Azure VMs within a single region. The application tier is deployed across multiple VMs. They need to protect against a failure of an entire Azure datacenter within that region. The solution should automatically distribute the VMs across physically separate locations with independent power, cooling, and networking. The company also requires the lowest possible latency between application and database tiers within the same location. Which deployment strategy should they use?

Accepted Answer

Deploy the VMs across multiple availability zones. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Deploying the application tier VMs across multiple zones protects against an entire datacenter failure while keeping all resources within the same region, ensuring the lowest possible latency between application and database tiers when they are placed in the same zone.

Answer

Deploy the VMs in an availability set

Answer

Use Azure Site Recovery to replicate VMs to a paired region

Answer

Use Azure Proximity Placement Groups

Answer

Enable Azure Site Recovery for the App Service

Question 12

A company runs a critical application on Azure Kubernetes Service (AKS) in a single region. The application is stateless and uses an Azure SQL Database with active geo-replication for database DR. They need to ensure the AKS cluster can failover to a secondary region with an RTO of 15 minutes and an RPO of 5 seconds for the database. What should they recommend for the AKS cluster?

Accepted Answer

Deploy AKS clusters in two regions and use Azure Traffic Manager to route traffic.. Option A is correct because deploying AKS clusters in two regions with Azure Traffic Manager enables active-passive or active-active failover. Traffic Manager uses DNS-based routing to direct traffic to the secondary region when the primary fails, meeting the RTO of 15 minutes. The stateless application can be redeployed or scaled in the secondary cluster, while the Azure SQL Database with active geo-replication ensures an RPO of 5 seconds by continuously replicating transactions.

Answer

Deploy a single AKS cluster with pods spread across availability zones within the region.

Answer

Use Azure Site Recovery to replicate the AKS cluster to another region.

Answer

Back up the AKS cluster configuration and container images to a geo-redundant storage account.

Question 13

A company runs an application on Azure VMs that must be backed up according to regulatory compliance: daily backups retained for 30 days, weekly backups retained for 12 months, and yearly backups retained for 7 years. The backups must be stored in a secondary region for disaster recovery. They want to use Azure Backup for VMs. Which backup policy and storage configuration should they implement?

Accepted Answer

Configure a backup policy in Azure Backup for VMs with daily, weekly, and yearly retention rules, and enable cross-region restore by using a Recovery Services Vault with geo-redundant storage.. Option A is correct because Azure Backup for VMs allows you to create a custom backup policy with daily, weekly, and yearly retention points, meeting the regulatory requirements. By enabling cross-region restore (CRR) on a Recovery Services Vault configured with geo-redundant storage (GRS), backups are automatically replicated to a paired secondary region, providing disaster recovery without additional infrastructure.

Answer

Enable backup with Azure Backup using the default policy and select Geo-Redundant Storage (GRS) for the Recovery Services Vault.

Answer

Use Azure Site Recovery to replicate VMs to the secondary region and configure retention policies in the replication settings.

Answer

Perform file-level backups using Azure Backup and store them in a separate storage account with read-access geo-redundant storage (RA-GRS).

Question 14

A company runs a critical application on Azure Virtual Machines in a single availability set. They want to protect against an entire Azure region failure. They need a recovery time objective (RTO) of 30 minutes and a recovery point objective (RPO) of 15 minutes. Which solution should they use?

Accepted Answer

Azure Site Recovery to another region.. Azure Site Recovery (ASR) provides orchestrated replication, failover, and failback of Azure VMs to a secondary region, enabling a recovery time objective (RTO) of 30 minutes and a recovery point objective (RPO) of 15 minutes as required. ASR replicates VM disks continuously to the target region, and in a regional failure, you can initiate a planned or unplanned failover to bring up the application within the specified RTO/RPO. This is the only option that offers both cross-region disaster recovery and the granular recovery objectives stated.
