AZ-305 Practice Test 21 — 15 Questions

Question 1

A company wants to protect Azure VMs from accidental deletion or corruption by retaining daily backups for 30 days, weekly backups for 12 weeks, monthly backups for 12 months, and yearly backups for 7 years. Which backup policy type should they use?

Accepted Answer

Azure Backup GFS policy. Option B is correct because Azure Backup supports a Grandfather-Father-Son (GFS) backup policy that allows retention of daily, weekly, monthly, and yearly backups with different retention periods. Option A is wrong because a simple daily backup policy cannot specify multiple retention tiers. Option C is wrong because the Enhanced policy is for SQL Server, not general VM backup. Option D is wrong because a monthly backup policy cannot include daily or weekly backups.

Answer

Daily backup policy with 30-day retention

Answer

Monthly backup policy with 12-month retention

Answer

Azure Backup Enhanced policy

Question 2

Your company runs a critical e-commerce application on Azure Virtual Machines (VMs) in a single region. You need to design a disaster recovery (DR) solution that meets a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour for the application tier. The application uses Azure SQL Database (single database). Which combination of Azure services should you recommend to meet the RPO and RTO?

Accepted Answer

Use Azure Site Recovery for VM replication to a secondary region and Azure SQL Database active geo-replication. Option B is correct because Azure Site Recovery can replicate VMs to a secondary region with an RPO of 15 minutes and RTO of 1 hour for the application tier. Azure SQL Database active geo-replication provides an RPO of 5 seconds and RTO of 1 hour. Option A is wrong because Azure Backup has a higher RPO (typically 12 hours for VMs). Option C is wrong because read-scale replicas do not support failover. Option D is wrong because Azure Front Door is for global load balancing, not DR replication.

Answer

Use Azure Site Recovery for VMs and Azure SQL Database read-scale replicas

Answer

Use Azure Backup for VM replication and Azure SQL Database auto-failover groups

Answer

Use Azure Front Door with regional load balancing and Azure SQL Database geo-restore

Question 3

Refer to the exhibit. You are reviewing an Azure Site Recovery replicated item for a VM. The replication health is Normal, and the last recovery point is at 10:30 AM. The primary region experiences a failure at 10:35 AM. You initiate a failover at 10:40 AM. What is the maximum potential data loss?

Accepted Answer

5 minutes of data. Option A is correct because the last recovery point is at 10:30 AM, and the failure occurred at 10:35 AM. The data loss is up to 5 minutes of data (between 10:30 and 10:35). Option B is wrong because the RPO is defined by the policy, but the actual loss is based on the last recovery point. Options C and D are incorrect.

Answer

15 minutes of data

Answer

0 minutes of data

Answer

10 minutes of data

Question 4

Your company runs an on-premises application that needs to be failed over to Azure in the event of a disaster. The application uses a SQL Server database and requires an RPO of 15 minutes and an RTO of 1 hour. You plan to use Azure Site Recovery (ASR) for the VMs and Azure SQL Database for the database. Which combination of actions should you take?

Accepted Answer

Use ASR with 15-minute replication for the VMs and configure a failover group for Azure SQL Database with active geo-replication.. Option C (ASR for VMs with 15-minute replication and SQL Database failover group) meets both RPO and RTO. Option A (longer RPO). Option B (manual restore) does not meet RTO. Option D (Log Shipping) is not native to Azure SQL Database.

Answer

Use ASR with 5-minute replication and configure SQL Server Log Shipping to an Azure VM.

Answer

Use ASR with 30-minute replication frequency and backup the SQL Server database every 15 minutes.

Answer

Use ASR with 15-minute replication and restore the SQL Server database from backup.

Question 5

Refer to the exhibit. You deploy an Azure SQL Database with a secondary replica in another region using the ARM template shown. You need to ensure that the database can fail over automatically with zero data loss. What is missing?

Accepted Answer

Create a failover group that includes both databases.. Option B (failover group) is required to orchestrate automatic failover. Option A (zone redundancy) not needed. Option C (read scale) not needed. Option D (backup) irrelevant.

Answer

Configure long-term backup retention.

Answer

Disable readScaleOut on the primary database.

Answer

Set zoneRedundant to true on the primary database.

Question 6

A company runs a containerized application on Azure Container Instances (ACI) in a single region. The application uses Azure Cosmos DB (SQL API) with a single write region. You need to design a disaster recovery solution that meets an RPO of 0 seconds and RTO of 10 minutes for a regional outage. The solution must be cost-optimized. What should you include in the design?

Accepted Answer

Migrate the application to Azure Kubernetes Service (AKS) deployed in two regions, use Azure Front Door, and configure Cosmos DB with multi-region writes.. Option D is correct because ACI does not support built-in multi-region deployment; using AKS with Azure Front Door and Cosmos DB multi-region writes provides RPO=0 and fast failover. Option A uses Azure Container Registry for replication but not compute failover. Option B uses Cosmos DB conflict resolution but ACI is single-region. Option C uses manual steps which exceed RTO.

Answer

Use Azure Container Instances with container groups across availability zones, and configure Cosmos DB geo-replication with manual failover.

Answer

Deploy ACI containers in two regions, use Azure Traffic Manager, and configure Cosmos DB with automatic failover.

Answer

Deploy ACI containers in two regions, use Azure Front Door, and configure Cosmos DB with multi-region writes.

Question 7

Which TWO Azure services can be used to automatically redirect traffic to an alternate region in the event of a regional outage? (Choose two.)

Accepted Answer

Azure Traffic Manager. Azure Traffic Manager and Azure Front Door both provide global load balancing with automatic failover. Option A is incorrect because Application Gateway is regional. Option D is incorrect because Azure Load Balancer is regional. Option E is incorrect because Azure DNS does not provide traffic redirection based on health.

Answer

Azure Application Gateway

Answer

Azure Load Balancer

Answer

Azure DNS

Question 8

A company runs a critical SAP HANA database on an Azure large instance. They need a disaster recovery solution that provides automatic failover to a secondary region with an RPO of 15 minutes and RTO of 30 minutes. The solution must not require manual intervention to start replication. What should they use?

Accepted Answer

SAP HANA System Replication with HANA Pacemaker. Option B is correct because SAP HANA System Replication with HANA Pacemaker can provide automatic failover with an RPO of 15 minutes and RTO of 30 minutes. Option A is wrong because Azure Site Recovery for SAP HANA requires manual steps to start replication. Option C is wrong because Azure Backup for SAP HANA has a higher RPO. Option D is wrong because Azure NetApp Files is a storage solution, not a replication mechanism.

Answer

Azure Site Recovery with replication policy for SAP HANA

Answer

Azure NetApp Files with cross-region replication

Answer

Azure Backup for SAP HANA

Question 9

A healthcare organization stores patient records in Azure Blob Storage with a hot access tier in the East US region. The compliance policy requires that data be recoverable within 1 hour in the event of a regional disaster. The data is updated every 10 minutes and must be recoverable to a consistent state within 15 minutes of failure. Which configuration should you implement?

Accepted Answer

Use object replication with a minimum RPO of 15 minutes and configure read-access in the secondary region. Option D is correct because object replication with a minimum Replication Time Objective (RTO) of 15 minutes meets the RPO requirement, and a secondary read-access region meets the RTO of 1 hour. Option A is wrong because RA-GRS has an RPO of 15 minutes but failover is manual and may take longer. Option B is wrong because GZRS with manual failover may exceed RTO. Option C is wrong because geo-redundant storage (GRS) does not provide read access in the secondary region.

Answer

Use RA-GRS (read-access geo-redundant storage) and configure storage account failover

Answer

Use GRS (geo-redundant storage) with automated failover

Answer

Use GZRS (geo-zone-redundant storage) with customer-managed failover

Question 10

Your company uses Azure Backup to protect on-premises file servers and Azure VMs. The compliance team requires that backup data be stored in a secondary region to protect against regional disasters. Which Azure Backup feature should you enable?

Accepted Answer

Enable geo-redundant storage (GRS) for the Recovery Services vault. Option B is correct because Azure Backup allows configuring a Recovery Services vault with geo-redundant storage (GRS) to replicate backup data to a paired region. Option A is wrong because Recovery Services vault is the container, not the replication feature. Option C is wrong because Back up to a secondary region is not supported directly. Option D is wrong because Azure Site Recovery is for replication, not backup.

Answer

Use Azure Site Recovery to replicate the backup data

Answer

Configure backup policies to back up directly to the secondary region

Answer

Use a Recovery Services vault in the secondary region

Question 11

You are designing a disaster recovery plan for a critical application that runs on Azure VMs. The VMs are in a single region and are backed up daily. The RPO is 1 hour and the RTO is 4 hours. The current backup solution cannot meet the RPO. You need to recommend a solution that meets the requirements with minimal cost. What should you do?

Accepted Answer

Implement Azure Site Recovery with a replication policy of 30 minutes.. Option B (ASR with replication frequency of 30 minutes) meets RPO and RTO with lower cost than continuous replication. Option A (backup every 30 minutes) increases cost without meeting RTO. Option C (continuous replication) is more expensive. Option D (always-on availability groups) requires additional licenses.

Answer

Configure SQL Server Always On Availability Groups across two Azure regions.

Answer

Increase the backup frequency to every 30 minutes.

Answer

Implement Azure Site Recovery with a replication policy of 15 minutes.

Question 12

Refer to the exhibit. You are configuring Azure Site Recovery replication for a VM. The exhibit shows the replication policy settings. What is the RPO and RTO that can be achieved with this policy?

Accepted Answer

RPO of 5 minutes and RTO of 15 minutes.. Option B (RPO 5 min, RTO 15 min) matches the settings (300 seconds = 5 min, 900 seconds = 15 min). Option A (RPO 15 min) is wrong. Option C (RPO 5 min, RTO 30 min) wrong. Option D (RPO 10 min) wrong.

Answer

RPO of 15 minutes and RTO of 5 minutes.

Answer

RPO of 5 minutes and RTO of 30 minutes.

Answer

RPO of 10 minutes and RTO of 15 minutes.

Question 13

Which TWO of the following are valid strategies for achieving high availability for Azure SQL Database?

Accepted Answer

Deploy Azure SQL Database in a zone-redundant configuration within a single region.. Options B and D are correct. Active geo-replication provides readable secondaries and supports manual failover. Zone-redundant configuration protects against datacenter failure within a region. Option A (auto-failover groups) is a strategy but is a superset; the question asks for strategies. Option C (backup to another region) is for disaster recovery, not high availability. Option E (read scale-out) is for read scalability, not availability.

Answer

Enable read scale-out to distribute read queries to a secondary replica.

Answer

Use Azure Backup to copy database backups to another region.

Answer

Configure auto-failover groups with a secondary in another region.

Question 14

Refer to the exhibit. A role assignment has a condition that controls blob deletion. A user assigned this role tries to delete a blob with tag 'Project' set to 'ProjectB'. What will happen?

Accepted Answer

The deletion is denied because the blob does not have the required tag. Option D is correct because the condition grants delete permission only if the blob's tag matches 'ProjectA'. Since the blob has tag 'ProjectB', the condition evaluates to false, and the delete action is denied. Option A is wrong because the condition does not block all blob deletions, only those not matching the tag. Option B is wrong because the condition does not affect other actions. Option C is wrong because the condition is evaluated at runtime.

Answer

The deletion is allowed because the condition only applies to write operations

Answer

The deletion is allowed because the condition does not affect blob deletion

Answer

The deletion is denied because the condition version is 2.0 and not supported

Question 15

You are reviewing a recovery plan for Azure Site Recovery. The exhibit shows a snippet of the recovery plan configuration. What is the purpose of the script action defined in the exhibit?

Accepted Answer

To run a custom script on the recovered VMs after they boot up during test and unplanned failover.. The script action runs a PowerShell script after the VMs boot (during the Boot group) for test and unplanned failovers. This script is typically used to perform post-failover tasks such as updating DNS records or configuring application settings. Option A is incorrect because the script runs after boot, not before shutdown. Option C is incorrect because the script runs only for specific failover directions. Option D is incorrect because the script is not limited to planned failover.

Answer

To run a script before the VMs shut down during failover.

Answer

To update the Azure DNS records after failover.

Answer

To run a script only during planned failover from the primary to the recovery region.
