Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has an on-premises Hyper-V environment with 20 virtual machines running various workloads. They want to use Azure as a disaster recovery site. The required recovery point objective (RPO) is 15 minutes, and the recovery time objective (RTO) is 2 hours. They want to automate 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
Azure Site Recovery orchestrates replication, failover, and failback for Hyper-V VMs to Azure. It supports near-synchronous replication and custom RPOs down to 30 seconds.
B
Distractor review
Azure Migrate
Azure Migrate is used for discovering, assessing, and migrating on-premises workloads to Azure. It does not provide ongoing replication or disaster recovery failover.
C
Distractor review
Azure Backup
Azure Backup provides backup and restore, but it does not offer orchestrated failover to Azure or failback. RPO is typically once per day, not 15 minutes.
D
Distractor review
Azure Recovery Services Vault
The Recovery Services vault is a container used by both Azure Backup and Azure Site Recovery. It is not a service itself; you must enable either Backup or Site Recovery within it.
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) provides disaster recovery for Hyper-V VMs by replicating them to Azure storage. It supports replication intervals as low as 30 seconds, easily meeting the 15-minute RPO. ASR allows automated failover to Azure and failback to on-premises. Azure Migrate is for assessment and migration, not ongoing replication with failover. Azure Backup is for backup, not full disaster recovery with orchestrated failover. Azure Recovery Services vault is used by both ASR and Backup, but ASR is the correct service.
