AZ-305 Practice Test 26 — 15 Questions

Question 1

A company wants to ensure that their Azure Storage account containing blobs is protected against accidental deletion or corruption. The solution must enable recovery of previous versions up to 30 days. Which TWO features should they enable? (Choose TWO.)

Accepted Answer

Blob versioning. Options A and C are correct. Blob soft delete allows recovery of deleted blobs, and versioning keeps previous versions of blobs. Together, they provide protection against deletion and corruption with 30-day retention. Option B is wrong because point-in-time restore is for Azure Files. Option D is wrong because change feed tracks changes but does not enable recovery. Option E is wrong because Azure Backup for blobs is an alternative but not the combination requested.

Answer

Change feed

Answer

Azure Backup for Azure Blobs

Answer

Point-in-time restore for Azure Files

Question 2

Your company runs a mission-critical application on Azure Virtual Machines that requires a Recovery Time Objective (RTO) of 5 minutes and a Recovery Point Objective (RPO) of 1 minute. The application uses a single VM with a managed disk. You need to design a disaster recovery solution that meets these requirements with minimal cost. What should you recommend?

Accepted Answer

Use Azure Site Recovery to replicate the VM to a secondary region with a recovery plan.. Option C is correct because Azure Site Recovery can replicate Azure VMs with a disk-level RPO of 5 seconds and RTO of minutes, meeting the requirements. Option A is wrong because Azure Backup has a minimum RPO of 1 hour for VMs. Option B is wrong because read-access geo-redundant storage does not replicate the VM configuration. Option D is wrong because a secondary VM with replication would be more expensive than Azure Site Recovery's pay-as-you-go model.

Answer

Configure Azure Backup for the VM with a 1-minute backup frequency.

Answer

Store the managed disk in geo-redundant storage and use Azure Resource Manager templates to redeploy.

Answer

Deploy a second VM in a secondary region and use continuous replication with Azure Migrate.

Question 3

A company uses Azure Backup to protect on-premises file servers via the Azure Backup Server (MABS). They want to ensure backups are retained for 10 years for compliance. What backup tier should they use?

Accepted Answer

Azure Backup with GFS retention policy for monthly and yearly points. Option B is correct because Azure Backup supports long-term retention (up to 99 years) using the Backup vault's Grandfather-Father-Son (GFS) retention policy with monthly and yearly points. Option A is wrong because Azure Site Recovery is for replication, not backup retention. Option C is wrong because the warm storage tier is for short-term retention. Option D is wrong because Azure Files is not a backup retention feature.

Answer

Azure Backup using the warm storage tier

Answer

Azure Files share snapshots

Answer

Azure Site Recovery

Question 4

You are designing a disaster recovery solution for a multi-tier web application on Azure VMs. The solution must meet an RPO of 15 minutes and an RTO of 1 hour. The application includes a SQL Server database. Which THREE actions should you take? (Choose THREE.)

Accepted Answer

Use Azure Premium SSD managed disks for the VMs to ensure low latency replication.. Options A, C, and E are correct. Azure Site Recovery can replicate the VMs with low RPO. For SQL Server, Always On Availability Groups provide automatic failover with minimal data loss. Using premium storage ensures performance. Option B is wrong because Azure Backup has a higher RPO. Option D is wrong because read-scale replicas do not provide failover.

Answer

Use Azure Backup for the SQL Server database with 1-hour backup frequency.

Answer

Deploy read-scale replicas of the SQL Server in the secondary region.

Question 5

Your organization has a critical application running on Azure Virtual Machines. You need to design a backup and disaster recovery strategy. Which TWO options should you include in your design to meet a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 1 hour? (Choose two.)

Accepted Answer

Implement Azure Site Recovery with replication to a secondary region.. Option B and Option D are correct. Azure Site Recovery can replicate VMs with an RPO as low as 15 minutes and an RTO of minutes to hours. Azure Backup can be used for additional long-term retention, but to meet the RPO/RTO requirements, Site Recovery is necessary. Option A is wrong because Azure Backup has a default RPO of 1 hour for VMs. Option C is wrong because Traffic Manager does not provide RPO/RTO guarantees. Option E is wrong because Azure Files is not a VM backup solution.

Answer

Store data in Azure Files and use Azure File Sync for replication.

Answer

Use Azure Traffic Manager to distribute traffic between regions.

Answer

Configure Azure Backup for daily backups with geo-redundant storage.

Question 6

Your organization runs a critical application on Azure VMs that must be highly available within a region. The application is stateful and requires shared storage. You need to design a solution that can automatically recover from a VM failure with minimal downtime. What should you include in the design?

Accepted Answer

Deploy the VMs in an availability set and use Azure Shared Disks for the stateful data.. Option A is correct because an availability set provides VM redundancy and a shared disk allows persistent storage that can be attached to the standby VM. Option B is wrong because Availability Zones provide cross-zone redundancy but not shared storage. Option C is wrong because Azure Files does not support direct attach to VMs. Option D is wrong because Azure Backup does not provide automatic failover.

Answer

Deploy a single VM with premium storage and Azure Backup for recovery.

Answer

Deploy the VMs in different Availability Zones and use Azure NetApp Files for storage.

Answer

Use Azure Site Recovery to replicate the VM to a secondary region.

Question 7

Refer to the exhibit. An administrator configured Azure Site Recovery replication for a VM using the policy shown. The VM workload is a critical database that requires application-consistent snapshots every 30 minutes to meet compliance. What is the issue with the current configuration?

Accepted Answer

The application-consistent snapshot frequency is 60 minutes, which is too high (should be 30 minutes).. Option B is correct because the application-consistent snapshot frequency is set to 60 minutes, which does not meet the requirement of 30 minutes. Option A is wrong because the recovery point retention is 1440 minutes (24 hours), which is sufficient. Option C is wrong because Standard_LRS is acceptable for replication. Option D is wrong because the target region eastus2 is valid.

Answer

The recovery point retention is set too low (1440 minutes).

Answer

The target region eastus2 is not a valid paired region for the source.

Answer

The storage account type is Standard_LRS; it should be Premium_LRS.

Question 8

You are designing a business continuity solution for a global SaaS application that runs on Azure Kubernetes Service (AKS) with Azure Cosmos DB as the database. The solution must support multi-region writes and automatic failover with zero data loss. Which THREE components should you include in your design? (Choose three.)

Accepted Answer

Deploy Azure Cache for Redis Enterprise with active geo-replication.. Option A, Option C, and Option D are correct. Azure Cosmos DB with multi-region writes supports zero data loss during failover. Azure Front Door provides global load balancing and automatic failover for the AKS clusters. Azure Cache for Redis Enterprise with active geo-replication provides low-latency cache with multi-region writes. Option B is wrong because Azure Traffic Manager is not required when using Front Door. Option E is wrong because Azure SQL Database does not support multi-region writes natively like Cosmos DB.

Answer

Use Azure Traffic Manager to route traffic to the primary region.

Answer

Use Azure SQL Database with failover groups for the database tier.

Question 9

You are designing a business continuity plan for a financial services company that uses Azure SQL Database for its transactional workloads. The solution must meet an RPO of 5 seconds and an RTO of 30 seconds during a regional outage. What should you use?

Accepted Answer

Azure SQL Database with active geo-replication and automatic failover. Option C is correct because Azure SQL Database failover groups with active geo-replication provide an RPO of 5 seconds and RTO of about 30 seconds when using automatic failover. Option A is wrong because auto-failover groups have an RPO of 5 seconds. Option B is wrong because Azure SQL Managed Instance failover groups have a higher RTO. Option D is wrong because Azure Database for PostgreSQL is not the same service.

Answer

Azure Database for PostgreSQL with read replicas in another region

Answer

Azure SQL Database auto-failover group with a secondary in a paired region

Answer

Azure SQL Managed Instance with failover group

Question 10

Your company is developing an application that will store transactional data in Azure SQL Database. The application has a Recovery Point Objective (RPO) of 5 seconds and a Recovery Time Objective (RTO) of 30 seconds. Which TWO Azure features should you recommend? (Choose two.)

Accepted Answer

Create an auto-failover group with a readable secondary in another Azure region.. Option A and Option D are correct. Auto-failover groups with active geo-replication provide synchronous replication with RPO of 0 and RTO of about 30 seconds. Option B is wrong because Azure Backup has an RPO of 5 minutes for SQL Database (full backup frequency). Option C is wrong because Azure Site Recovery does not replicate SQL Database natively. Option E is wrong because zone-redundant availability zones protect against datacenter failures, not regional failures, and RTO is not guaranteed.

Answer

Use Azure Site Recovery to replicate the SQL Database to a secondary region.

Answer

Deploy the Azure SQL Database across availability zones in the primary region.

Answer

Perform Azure SQL Database backups every 5 seconds using Azure Backup.

Question 11

Your company has an Azure subscription with a single virtual network. You need to design a solution to back up Azure VMs to meet a 7-day retention policy. The backup data must be stored in a separate region for compliance. What should you use?

Accepted Answer

Azure Backup with cross-region restore (CRR) enabled. Option D is correct because Azure Backup can be configured with cross-region restore (CRR) to store backup data in a paired region. Option A is wrong because Azure Site Recovery is for replication, not backup. Option B is wrong because Azure Backup's default is geo-redundant storage (GRS) which replicates to a paired region. Option C is wrong because Azure Files snapshots are for file shares, not VMs.

Answer

Azure Site Recovery with replication to a secondary region

Answer

Azure File Share snapshots stored in a different region

Answer

Azure Backup with default geo-redundant storage (GRS) in the same region

Question 12

Refer to the exhibit. You are reviewing the replication health of an on-premises Hyper-V VM replicated to Azure using Azure Site Recovery. The JSON output shows the properties of the replicated item. The replication health is 'Normal', but the last recovery point is from 2 hours ago. You need to ensure the Recovery Point Objective (RPO) of 15 minutes is met. What is the most likely cause of the issue?

Accepted Answer

The replication frequency is set to 30 minutes or more.. Option B is correct because the 'currentRecoveryPoint' timestamp being 2 hours old indicates that replication is not occurring frequently enough. Azure Site Recovery for Hyper-V VMs uses a replication frequency that can be set to 30 seconds, 5 minutes, or 15 minutes. If the last recovery point is 2 hours old, the replication frequency is likely set to a longer interval or there is a connectivity issue. Option A is wrong because the replication health is Normal, so provider registration is fine. Option C is wrong because a failed snapshot would show a different health status. Option D is wrong because the exhibit shows the recovery site is EastUS, indicating configuration is set.

Answer

The VM's application-consistent snapshot is failing.

Answer

The target region is not correctly configured in the recovery plan.

Answer

The Hyper-V host is not registered with the Recovery Services vault.

Question 13

You are designing a high-availability solution for a stateful application that uses Azure NetApp Files (ANF) for persistent storage. The application must withstand a zonal failure within a region. What should you do?

Accepted Answer

Use Azure NetApp Files cross-zone replication to replicate data between availability zones.. Option B is correct because ANF cross-zone replication (preview) replicates volumes across zones synchronously (with some lag) to provide zonal resilience. Option A is wrong because ANF doesn't support Availability Zones directly. Option C is wrong because Azure Files is not ANF. Option D is wrong because Azure Backup is not for real-time failover.

Answer

Use Azure Files with zone-redundant storage (ZRS) and SMB multi-channel.

Answer

Use Azure Backup for ANF with daily snapshots stored in a different zone.

Answer

Deploy the application in an Availability Set and use ANF volumes with zone-redundant storage (ZRS).

Question 14

A company wants to ensure that their Azure SQL Database can continue to serve read-write traffic if the primary region becomes unavailable. They require minimal data loss. What should they implement?

Accepted Answer

Configure an auto-failover group with a secondary in another region. Option C is correct because an auto-failover group with active geo-replication provides automated failover with minimal data loss. Option A is wrong because read-scale replicas are for read-only. Option B is wrong because Azure SQL Database does not use Availability Zones for cross-region DR. Option D is wrong because Azure Backup does not provide failover.

Answer

Use Azure Backup with cross-region restore

Answer

Deploy the database across two Availability Zones

Answer

Read-scale replicas in the same region

Question 15

Your company has a hybrid infrastructure with on-premises servers and Azure virtual machines. You need to design a backup strategy that includes on-premises file servers and Azure VMs. The solution must support long-term retention for compliance (7 years) and provide immediate recovery for recent versions. What should you include in the design?

Accepted Answer

Deploy Azure Backup with the Microsoft Azure Recovery Services (MARS) agent for on-premises and the Azure Backup extension for VMs.. Option C is correct because Azure Backup provides a unified backup solution for both on-premises (via MARS agent) and Azure VMs, with support for long-term retention using Backup Vault and Recovery Services vault. Option A is wrong because Azure Site Recovery is for disaster recovery, not backup. Option B is wrong because Azure File Sync syncs files but does not provide backup capabilities. Option D is wrong because Azure Storage snapshots are not a comprehensive backup solution with centralized management.

Answer

Use Azure Storage account snapshots for on-premises files and Azure VM snapshots for VMs.

Answer

Set up Azure File Sync to sync on-premises files to Azure Files, then back up the Azure file shares.

Answer

Use Azure Site Recovery for both on-premises servers and Azure VMs.
