Full question →mediummultiple choiceObjective-mapped
A company has an on-premises application running on physical servers with various operating systems. They want to use Azure as a disaster recovery site with an RPO of less than 1 hour and an RTO of less than 4 hours. They need to replicate the servers to Azure and support failover and failback. Which Azure service should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Azure Site Recovery
ASR provides continuous replication for physical servers to Azure, enabling failover and failback with RPO as low as 30 seconds and RTO in hours, meeting the requirements.
B
Distractor review
Azure Backup (MARS agent)
Azure Backup is designed for backup, not DR. It can take application-consistent backups but does not support rapid failover with an RTO of less than 4 hours. Failover would require restoring from backup, which takes longer.
C
Distractor review
Azure Migrate
Azure Migrate is for discovering, assessing, and migrating on-premises workloads to Azure. It does not provide ongoing replication or failover capabilities for DR.
D
Distractor review
Azure File Sync
Azure File Sync syncs on-premises file servers to Azure file shares. It does not replicate entire physical servers or support failover of applications.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Site Recovery — Azure Site Recovery (ASR) supports disaster recovery for on-premises physical servers by replicating them to Azure. It can handle various operating systems and provides orchestrated failover and failback capabilities with configurable RPO (typically minutes) and RTO (hours). Azure Backup (MARS agent) is for backup and restore, not rapid failover. Azure Migrate is for assessment and migration services. Azure File Sync is for syncing file shares. Therefore, ASR is the correct choice.
