CV0-004 Practice Question: Is designing a cloud architecture that must be…
An organization is designing a cloud architecture that must be fault-tolerant within a single region. The architect decides to deploy application instances in multiple Availability Zones (AZs). Which cloud characteristic is being leveraged?
⚠ Common exam trap
CompTIA often tests the distinction between resource pooling and elasticity, where candidates mistakenly think distributing across AZs is about scaling (elasticity) rather than leveraging the provider's shared physical infrastructure (resource pooling).

Correct answer & explanation
✓
Resource pooling
Deploying application instances across multiple Availability Zones (AZs) within a single region leverages resource pooling, a key cloud characteristic. Resource pooling allows the cloud provider to aggregate compute, storage, and network resources from multiple physical locations (AZs) into a shared pool that can be dynamically allocated to tenants. By distributing instances across AZs, the architect ensures that if one AZ fails, the application remains available using resources from other AZs, directly utilizing the provider's pooled 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.
- ✓
Resource pooling
Why this is correct
Resource pooling allows the provider to serve multiple customers and distribute resources across AZs for fault tolerance.
- ✗
Measured service
Why it's wrong here
Measured service relates to metering and billing.
- ✗
Elasticity
Why it's wrong here
Elasticity is about scaling resources up/down, not distribution across AZs.
- ✗
On-demand self-service
Why it's wrong here
On-demand self-service is the ability to provision resources without human interaction.
