Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company runs its line-of-business application on a virtual machine in an on-premises data center. The business continuity team wants to replicate the entire server (including operating system, applications, and data) to Azure so that if the on-premises site fails, the workload can be quickly started in an Azure region. The team also needs the ability to perform non-disruptive disaster recovery drills to validate the failover process. Which Azure service should the team 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 (ASR) is correct because it provides continuous replication of on-premises VMs and physical servers to Azure, enabling orchestrated failover and test failovers for disaster recovery.
B
Distractor review
Azure Backup
Azure Backup is incorrect because it is designed for backing up files, folders, and virtual machine data for recovery points, not for replicating an entire server with failover capabilities and drill testing.
C
Distractor review
Azure Migrate
Azure Migrate is incorrect because it is a tool for assessing and migrating on-premises workloads to Azure, not for ongoing replication or disaster recovery failover.
D
Distractor review
Azure Traffic Manager
Azure Traffic Manager is incorrect because it is a DNS-based traffic load balancer that distributes user traffic across endpoints, not a disaster recovery replication service.
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-900 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) is the correct service for orchestrating disaster recovery and replication of workloads to Azure. It supports continuous replication of on-premises VMs and physical servers, allowing orchestrated failover to Azure when a disaster occurs. ASR also enables non-disruptive test failovers, which meet the requirement for drills without affecting the production environment. Azure Backup is designed for long-term backup and restore of data, not for full server replication with failover capabilities. Azure Migrate is a discovery and migration tool, not a disaster recovery service. Azure Traffic Manager is a DNS-based traffic routing service that does not provide replication or failover of on-premises workloads.
