Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company runs critical Azure virtual machines (VMs) in the West US region. They need a disaster recovery solution that replicates VMs to East US. The recovery point objective (RPO) must be 15 minutes and the recovery time objective (RTO) must be 2 hours. The VMs use managed disks and the application requires consistent state across multiple VMs. They want to test failover without impacting production. 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
Distractor review
Azure Backup with backup policies set to 15-minute frequency
Azure Backup is designed for backup, not disaster recovery with failover orchestration. It does not support multi-VM consistent recovery or test failover in the same way.
B
Distractor review
Azure Site Recovery with crash-consistent replication
Crash-consistent replication does not guarantee application consistency across multiple VMs, which is required for the application state.
C
Best answer
Azure Site Recovery with app-consistent replication
App-consistent replication ensures data integrity across VMs, meets the 15-minute RPO, and supports test failover without impact.
D
Distractor review
Azure Backup with application-consistent snapshot
Azure Backup can take app-consistent snapshots, but it is not designed for orchestrated DR to a secondary region with RTO of 2 hours.
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 with app-consistent replication — Azure Site Recovery (ASR) is the primary DR service for replicating Azure VMs to a secondary region. It supports app-consistent snapshots for multi-VM consistency, and offers a 15-minute RPO with default replication. ASR also allows non-disruptive test failovers. Azure Backup is for backup with longer RTO and does not provide orchestrated failover.
