Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company runs a mission-critical application on Azure virtual machines. The application is hosted in the East US Azure region. To protect against a regional disaster, the company configures Azure Site Recovery to replicate the VMs to a secondary region (West US). If a disaster occurs in East US, the company can initiate a failover to West US and bring the application back online within minutes using the replicated data. Which cloud computing benefit does this scenario best demonstrate?
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
Elasticity
Elasticity is the ability to automatically scale resources up and down based on demand. While Azure Site Recovery can be part of an elastic architecture, the primary benefit shown here is recovering from a disaster, not dynamic scaling.
B
Distractor review
Pay-as-you-go pricing
Pay-as-you-go means you only pay for the resources you consume. While Azure Site Recovery incurs costs based on replication, the central benefit illustrated is the ability to recover from a disaster, not the pricing model.
C
Best answer
Disaster recovery and business continuity
Correct. Disaster recovery and business continuity ensure that applications can be restored quickly after a disruptive event. This is a major cloud advantage, as it allows organizations to implement robust DR without significant upfront capital investment.
D
Distractor review
Geo-redundancy
Geo-redundancy refers to replicating data across multiple geographic locations to protect against datacenter failures. While Azure Site Recovery uses geo-replication, the benefit being demonstrated is the operational recovery (failover) itself, not just the storage redundancy. Geo-redundancy is a technical implementation detail, not the overarching business benefit.
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: Disaster recovery and business continuity — The scenario demonstrates disaster recovery (DR) and business continuity (BC), a key benefit of cloud computing. By replicating VMs to another region and enabling quick failover, the company avoids building a secondary physical datacenter and can restore operations rapidly after a disaster. This showcases how the cloud provides cost-effective and scalable DR capabilities.
