- A
Azure Backup for Azure VMs with application-consistent snapshots
Why wrong: This provides VM-level consistent backups, not SQL-application-consistent backups, and has limited support for granular database restore and long-term retention of individual databases.
- B
Azure Backup for SQL Server in Azure VMs
This offers true application-consistent backups for SQL Server databases, supports granular point-in-time restore, and allows retention of backups for up to 10 years using the archive tier, meeting the 7-year requirement.
- C
Azure Site Recovery
Why wrong: Azure Site Recovery is designed for disaster recovery replication, not for long-term backup retention. It does not provide the required backup lifecycle management or long-term retention capabilities.
- D
Azure Files
Why wrong: Azure Files is a fully managed file share service and does not offer backup capabilities for SQL Server databases. It is not a suitable solution for database backups.
Quick Answer
The answer is Azure Backup for SQL Server in Azure VMs, because it delivers native, application-consistent backups by leveraging the SQL Server VSS writer to ensure transactional integrity for databases running on Azure VMs. This service is purpose-built for database-level protection, allowing you to back up SQL Server databases separately from the VM-level backup, and it supports long-term retention of up to 10 years—exceeding the 7-year compliance requirement—while minimizing administrative overhead through automated scheduling and retention policy management. On the AZ-305 exam, this scenario tests your ability to differentiate between workload-specific backup solutions (like Azure Backup for SQL Server) and general VM backup; a common trap is choosing Azure Backup for Azure VMs alone, which captures the entire disk but cannot guarantee SQL Server transactional consistency. Remember the memory tip: “SQL needs its own backup—VSS writer for consistency, 10-year retention for compliance.”
AZ-305 Design business continuity solutions Practice Question
This AZ-305 practice question tests your understanding of design business continuity solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?

Correct answer & explanation
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'application-consistent snapshots' at the VM level with true SQL Server–aware database backups, overlooking that VM-level backups do not guarantee SQL Server transactional integrity or support database-level restore and long-term retention policies.
Detailed technical explanation
How to think about this question
Azure Backup for SQL Server in Azure VMs uses the SQL Server VSS writer to orchestrate a freeze-and-thaw cycle, ensuring that all transactions are committed and logs are flushed before the snapshot is taken, guaranteeing transactional integrity. Under the hood, it stores backups in a Recovery Services vault and supports full, differential, and log backups, with retention policies that can span up to 10 years using the backup tiering feature to archive older backups to cool or cold storage. In a real-world scenario, if a database requires point-in-time recovery to a specific second within a 7-year compliance window, this service can restore from log backups, whereas VM-level snapshots cannot achieve that granularity.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
