CLF-C02 Cloud Concepts Practice Question
A company wants to take advantage of AWS's global infrastructure to replicate their database to a second geographic region for disaster recovery. Which benefit of cloud computing does this leverage?
⚠ Common exam trap
A common mix-up: candidates confuse 'go global in minutes' with 'economies of scale' or 'speed and agility,' but the question specifically asks about leveraging global infrastructure for geographic replication, not cost savings or experimental speed.

Correct answer & explanation
✓
Go global in minutes
AWS's global infrastructure allows you to deploy resources, such as database replicas, across multiple geographic regions in minutes. By using services like Amazon RDS Cross-Region Read Replicas or Aurora Global Database, you can replicate data to a second region for disaster recovery, leveraging the cloud's ability to rapidly expand globally without provisioning physical data centers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Economies of scale
Why it's wrong here
This benefit explains that as AWS purchases compute, storage, and networking at massive scale, it passes the resulting cost savings to customers through lower pay-as-you-go prices. It is a unit-cost advantage driven by aggregated purchasing power, and it has nothing to do with the ability to run applications in multiple parts of the world. Choosing this answer would incorrectly map a pricing benefit to a geographic infrastructure benefit.
- ✗
Trade capital expense for variable expense
Why it's wrong here
This option describes the shift from purchasing and maintaining physical data centers (a capital expense) to paying only for the IT resources you consume (a variable expense). That pay-as-you-go model is a core AWS pricing advantage, but it addresses financing structure, not how quickly you can extend operations into a new country or continent. The question is about geographic reach, not cost accounting.
- ✓
Go global in minutes
Why this is correct
AWS operates data centers in dozens of geographic Regions around the world, and every Region exposes the same APIs, console, and infrastructure services. This lets you replicate a workload into a new Region in minutes by changing a region parameter or using global services like CloudFront and Route 53, without leasing land or installing hardware. This is the 'go global in minutes' benefit of cloud computing, enabling low-latency deployment, disaster recovery, and global customer reach.
- ✗
Increase speed and agility for experiments
Why it's wrong here
This benefit refers to reducing the time it takes to provision resources for development, so teams can spin up and tear down environments quickly and run more experiments at lower cost. While this is an important cloud advantage, it is distinct from 'go global in minutes' because it targets the pace of the software iteration cycle, not the speed of geographic expansion. Mixing the two benefits confuses development velocity with infrastructure reach.
