AZ-305 Practice Test 23 — 15 Questions

Question 1

A company needs to design a disaster recovery solution for a multi-tier application that includes a web tier, a business tier, and a database tier. The solution must meet the following requirements:
- RPO of 15 minutes for the database
- RTO of 1 hour for the entire application
- Automatic failover for the database
- No data loss for the web and business tiers (stateless)
Which TWO services should be included in the solution? (Choose two.)

Accepted Answer

Azure Traffic Manager. Option B and Option D are correct. Azure SQL Database active geo-replication provides automatic failover with an RPO of 5 seconds, well within 15 minutes. Azure Traffic Manager can route traffic to the secondary region stateless tiers. Option A is wrong because Azure Site Recovery is not needed for stateless tiers; they can be redeployed. Option C is wrong because Azure Front Door is not necessary for a simple DR scenario. Option E is wrong because Azure Backup does not provide automatic failover.

Answer

Azure Backup

Answer

Azure Site Recovery for VM replication

Answer

Azure Front Door

Question 2

Your company has a hybrid identity solution with Microsoft Entra ID Connect syncing on-premises Active Directory to Microsoft Entra ID. You need to design a business continuity solution for the identity service in case of an on-premises outage. The solution must allow users to authenticate and access cloud applications even if the on-premises domain controllers are unavailable. Which feature should you enable?

Accepted Answer

Password hash synchronization. Option C is correct because Microsoft Entra Connect sync provides password hash synchronization, which allows cloud authentication even if on-premises DCs are down. Option A is wrong because pass-through authentication requires on-premises agents. Option B is wrong because federation requires on-premises AD FS. Option D is wrong because Seamless SSO relies on on-premises authentication.

Answer

Federation with AD FS in a secondary on-premises site

Answer

Seamless Single Sign-On

Answer

Pass-through authentication with an agent in a secondary on-premises site

Question 3

You are designing a business continuity solution for a critical application that uses Azure Cosmos DB with multiple write regions. The application is deployed in the East US and West Europe regions. The business requires that if one region fails, the application can continue to serve writes in the remaining region with no data loss. Which consistency level should you use?

Accepted Answer

Strong. Option A is correct because strong consistency guarantees linearizability and no data loss during regional failover. However, it may affect write performance. Option B is wrong because bounded staleness can lose data if the staleness window is exceeded. Option C is wrong because session consistency may lose data. Option D is wrong because eventual consistency can lose data.

Answer

Eventual

Answer

Session

Answer

Bounded staleness

Question 4

Your company runs a mission-critical application on Azure VMs in a single region. The application requires an RPO of 5 minutes and an RTO of 30 minutes. You plan to use Azure Site Recovery (ASR) to replicate the VMs to a secondary region. The VMs use managed disks. However, during a disaster recovery drill, you discover that the failover takes longer than expected. What is the most likely cause?

Accepted Answer

The VMs have large attached data disks that require significant time to synchronize.. Option B (large disk size) is a common cause of slow failover due to replication latency. Option A (network) is less likely if configured correctly. Option C (recovery plan) does not affect failover time. Option D (hybrid benefit) irrelevant.

Answer

The replication policy is set to 30 minutes.

Answer

The Azure Hybrid Benefit is not applied to the VMs.

Answer

The recovery plan includes too many manual steps.

Question 5

A company runs a critical financial application on Azure Kubernetes Service (AKS) in a single region. The application uses Azure Cosmos DB for NoSQL with multiple write regions. You need to design a business continuity solution that meets an RPO of 0 seconds and an RTO of less than 5 seconds for a regional outage. The solution must be cost-optimized. What should you include in the design?

Accepted Answer

Deploy AKS clusters in two regions, use Azure Front Door to route traffic, and configure Azure Cosmos DB with multiple write regions and automatic failover.. Option A is correct because AKS can be deployed across Azure regions with Azure Front Door for global load balancing; Cosmos DB multi-region writes provide RPO=0 and automatic failover within seconds. Option B uses Azure Traffic Manager which does not provide instant failover. Option C uses Azure SQL Database which does not offer RPO=0 across regions. Option D uses manual failover which increases RTO.

Answer

Deploy AKS clusters in two regions, use Azure Traffic Manager with priority routing, and configure Azure Cosmos DB with a single write region and a readable secondary.

Answer

Deploy AKS clusters across availability zones in one region, use Azure Load Balancer, and configure Azure SQL Database with active geo-replication.

Answer

Deploy AKS clusters in two regions, use Azure Front Door, and configure Azure Cosmos DB with a single write region and manual failover.

Question 6

Which TWO actions should you take to ensure business continuity for an Azure SQL Managed Instance? (Choose two.)

Accepted Answer

Enable automated backups with a retention period that meets your RPO. Options B and D are correct. Azure SQL Managed Instance supports automated backups with point-in-time restore (B) and failover groups for geo-replication (D). Option A is wrong because configuring a readable secondary is not directly supported; failover groups handle that. Option C is wrong because Azure Site Recovery is for VMs, not managed instances. Option E is wrong because long-term retention is for backup storage, not failover.

Answer

Use Azure Site Recovery to replicate the instance to another region

Answer

Configure a readable secondary replica in the same region

Answer

Enable long-term retention (LTR) for backups

Question 7

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. Option B is correct because Azure Site Recovery can replicate VMs to a secondary Azure region with a recovery point objective (RPO) as low as 5 minutes and recovery time objective (RTO) measured in minutes. Option A is wrong because Azure Front Door provides global load balancing and caching, but does not handle VM replication. Option C is wrong because Azure Backup has a minimum RPO of 12 hours for VMs. Option D is wrong because Azure Traffic Manager only provides DNS-based traffic routing, not VM replication.

Answer

Azure Backup

Answer

Azure Traffic Manager

Answer

Azure Front Door

Question 8

A company runs a critical application on Azure VMs. They need a backup strategy that meets the following requirements:
- Daily backups retained for 35 days
- Weekly backups retained for 12 weeks
- Monthly backups retained for 36 months
- Yearly backups retained for 10 years
- Backups must be stored in a geo-redundant storage account
Which THREE items must be configured? (Choose three.)

Accepted Answer

A backup policy with GFS retention. Options A, C, and E are correct. A GFS backup policy is required to specify different retention rules for daily, weekly, monthly, and yearly backups. A Recovery Services vault in the same region as the VMs is needed. Geo-redundant storage (GRS) is required. Option B is wrong because the vault must be in the same region as the VMs, not the paired region. Option D is wrong because a backup policy is needed, not just a vault.

Answer

A simple daily backup policy

Answer

A Recovery Services vault in the paired region

Question 9

Which THREE Azure services can be used to implement a disaster recovery plan for Azure Virtual Desktop (AVD) that meets an RTO of 2 hours and an RPO of 30 minutes? (Select THREE.)

Accepted Answer

Azure Site Recovery. Options A, C, and E are correct. Azure Site Recovery can replicate AVD session host VMs. Azure Files can store FSLogix profiles in a geo-redundant storage account. Azure Backup can back up the AVD configuration and user data. Options B and D are wrong: Azure Migrate is for migration, not DR; Azure Database for MySQL is not typically part of AVD.

Answer

Azure Database for MySQL

Answer

Azure Migrate

Question 10

A company runs a critical SQL Server database on an Azure VM. The database is used by a line-of-business application that requires minimal data loss (RPO of 5 seconds) and fast recovery (RTO of 15 minutes). The VM is in a single region. What should you recommend to meet the RPO and RTO requirements?

Accepted Answer

Migrate the database to Azure SQL Managed Instance and configure a failover group with a secondary in another region.. Option D (Azure SQL Managed Instance with failover group) provides automated replication with RPO of seconds and RTO of minutes. Option A (backup to Azure Blob) has higher RPO/RTO. Option B (Availability Set) protects against host failure but not region failure. Option C (geo-redundant storage) does not protect against database corruption.

Answer

Use Azure Storage geo-redundant storage (GRS) for the VM's managed disks.

Answer

Deploy the VM in an Availability Set and use SQL Server Always On Availability Groups.

Answer

Configure Azure Backup for the VM with application-consistent backups every 5 minutes.

Question 11

A company needs to back up an Azure virtual machine that runs a file server. They want to restore individual files quickly without restoring the entire VM. Which backup option should they use?

Accepted Answer

Azure Backup for Azure VMs with file-level restore.. Option B (Azure Backup with file-level restore) allows restoring individual files. Option A (VM backup) is whole VM. Option C (Azure Files sync) is backup, not restore. Option D (snapshots) not integrated.

Answer

Azure File Sync with cloud tiering.

Answer

Azure Backup using MARS agent with file and folder backup.

Answer

Azure Backup for Azure VMs with instant restore.

Question 12

Your company has an on-premises database running SQL Server 2019. You plan to migrate to Azure SQL Managed Instance. The business requires a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 4 hours for a regional disaster. You need to design the disaster recovery solution. What should you use?

Accepted Answer

Configure a failover group between two Azure SQL Managed Instances in different regions with manual failover.. Option A is correct because Azure SQL Managed Instance failover group with manual failover meets RPO of 15 minutes (replication delay typically less than 10 seconds) and RTO of 4 hours (manual failover takes minutes). Option B has RTO of 12 hours for geo-restore. Option C auto-failover may cause unwanted failovers. Option D log shipping is not supported in managed instance.

Answer

Configure a failover group between two Azure SQL Managed Instances in different regions with automatic failover.

Answer

Use SQL Server log shipping from on-premises to Azure SQL Managed Instance in a secondary region.

Answer

Configure geo-restore of Azure SQL Managed Instance backups to a secondary region.

Question 13

A company runs a critical application on Azure VMs in a single region. They need to ensure the application can failover to another region with minimal data loss and a recovery time objective (RTO) of 1 hour. The application uses managed disks and SQL Server Always On availability groups. What is the MOST cost-effective solution that meets the requirements?

Accepted Answer

Use Azure Site Recovery to replicate VMs to a secondary region with a recovery plan. Option D is correct because Azure Site Recovery replicates VMs to a secondary region with near-synchronous replication (RPO of a few seconds) and provides orchestrated failover with RTO of minutes. It is more cost-effective than full active-passive setup. Option A is wrong because SQL Server Always On requires a secondary instance in the other region, which is more expensive and adds complexity beyond the VM recovery. Option B is wrong because geo-redundant storage (GRS) only provides storage-level replication, not full VM recovery. Option C is wrong because availability zones protect within a region, not cross-region.

Answer

Use Azure geo-redundant storage (GRS) for the managed disks and restore the VMs in the secondary region

Answer

Use Azure availability zones to protect against regional failures

Answer

Deploy SQL Server Always On availability groups across two regions

Question 14

Which THREE of the following are valid strategies for designing a disaster recovery plan for Azure Virtual Desktop? (Choose three.)

Accepted Answer

Use Azure File Sync to replicate FSLogix profile shares to a secondary region. Options A, B, and D are correct. Azure Site Recovery can replicate session host VMs (A). Azure Files can replicate FSLogix profiles using Azure File Sync to a secondary region (B). A disaster recovery plan can include a secondary host pool with pre-provisioned session hosts (D). Option C is wrong because Azure Backup does not provide immediate failover; it is for backup and restore. Option E is wrong because Azure Front Door is for web traffic, not for RDP connections.

Answer

Use Azure Front Door to route RDP traffic to the secondary region

Answer

Rely on Azure Backup to restore session hosts in the secondary region

Question 15

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. Option C is correct because SQL Server Always On Availability Groups with automatic failover can provide synchronous replication between VMs in different regions, offering no data loss and sub-minute RPO. Option A is wrong because Azure SQL Managed Instance failover groups provide automatic failover but with a maximum of one hour RPO for geo-replication. Option B is wrong because Azure SQL Database geo-replication has an RPO of up to 5 seconds, but the scenario specifies VMs, not PaaS. Option D is wrong because Azure Backup does not provide real-time replication.

Answer

Azure SQL Database geo-replication

Answer

Azure SQL Managed Instance failover groups

Answer

Azure Backup for SQL Server
