AZ-900 Describe cloud concepts Practice Question
A multinational company is expanding its online retail business to new countries. The company needs to deploy its web application in Azure regions that are geographically close to customers in Europe, Asia, and North America to minimize latency. The IT team can deploy identical application instances in multiple regions within minutes using Azure Resource Manager templates. Which benefit of cloud computing does this scenario best illustrate?
⚠ Common exam trap
A common mix-up: candidates confuse global reach with high availability or disaster recovery, but global reach specifically addresses geographic distribution for performance and compliance, not fault tolerance or failover.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Global reach
The scenario emphasizes deploying identical application instances in multiple Azure regions across Europe, Asia, and North America to serve customers geographically close to each region, which directly illustrates the global reach benefit of cloud computing. Azure Resource Manager (ARM) templates enable rapid, consistent deployment to any region, allowing the company to expand its global footprint and reduce latency by leveraging Azure's distributed infrastructure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
High availability
Why it's wrong here
High availability refers to keeping applications running despite component failures, usually through redundancy within a single region or across zones. The scenario is about deploying to multiple distant regions for latency reduction, not about maintaining uptime during failures.
When this WOULD be correct
A question describing a scenario where the company needs to ensure the web application remains accessible and operational despite the failure of one or more Azure regions, with automatic failover between regions, would make high availability the correct answer.
- ✗
Elasticity
Why it's wrong here
Elasticity is the ability to scale computing resources up or down automatically based on demand. The scenario does not mention scaling in response to load changes; it focuses on deploying identical instances in different geographic locations.
When this WOULD be correct
A company experiences sudden traffic spikes during holiday sales and needs its web application to automatically add virtual machines to handle the load, then remove them when demand drops. This would illustrate elasticity.
- ✓
Global reach
Why this is correct
Global reach (also called geographic distribution) is the cloud benefit that allows organizations to deploy applications and services in data centers around the world, reducing latency for users in different regions. The company is using this capability to serve customers in Europe, Asia, and North America with local instances.
- ✗
Disaster recovery
Why it's wrong here
Disaster recovery involves planning and infrastructure to recover from catastrophic failures, often by failing over to a secondary region. Although global deployment can support disaster recovery, the scenario's primary goal is minimizing latency for expanding business, not recovering from disasters.
When this WOULD be correct
A company needs to ensure its application can fail over to a secondary Azure region within minutes if the primary region experiences an outage. The ability to quickly deploy identical instances using templates supports disaster recovery.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-900 exam frequently reuses these exact scenarios with slightly different constraints.
✓Global reachCorrect answer▾
Why this is correct
Global reach (also called geographic distribution) is the cloud benefit that allows organizations to deploy applications and services in data centers around the world, reducing latency for users in different regions. The company is using this capability to serve customers in Europe, Asia, and North America with local instances.
✗High availabilityWrong answer — click to see why▾
Why this is wrong here
High availability focuses on ensuring application uptime and resilience to failures, not on deploying instances in multiple geographic regions to reduce latency for global customers.
★ When this WOULD be the correct answer
A question describing a scenario where the company needs to ensure the web application remains accessible and operational despite the failure of one or more Azure regions, with automatic failover between regions, would make high availability the correct answer.
Why candidates choose this
Candidates may confuse deploying in multiple regions with high availability, as both involve multiple instances, but high availability is about fault tolerance, not geographic proximity for latency reduction.
✗ElasticityWrong answer — click to see why▾
Why this is wrong here
Elasticity refers to the ability to scale resources up or down based on demand, not to deploying identical instances in multiple geographic regions. The scenario focuses on geographic distribution, not dynamic scaling.
★ When this WOULD be the correct answer
A company experiences sudden traffic spikes during holiday sales and needs its web application to automatically add virtual machines to handle the load, then remove them when demand drops. This would illustrate elasticity.
Why candidates choose this
Candidates may confuse rapid deployment of resources across regions with the ability to scale, as both involve quick provisioning. However, elasticity is about adjusting capacity within a region, not geographic distribution.
✗Disaster recoveryWrong answer — click to see why▾
Why this is wrong here
Disaster recovery focuses on restoring services after a failure, not on deploying identical instances in multiple regions to reduce latency. The scenario emphasizes geographic distribution for performance, not recovery from disasters.
★ When this WOULD be the correct answer
A company needs to ensure its application can fail over to a secondary Azure region within minutes if the primary region experiences an outage. The ability to quickly deploy identical instances using templates supports disaster recovery.
Why candidates choose this
Candidates may confuse deploying in multiple regions with disaster recovery, thinking that having instances in multiple regions inherently provides recovery capabilities, but the primary goal here is latency reduction, not recovery.
