This GCDL practice question tests your understanding of why cloud technology is transforming business. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization wants to ensure business continuity by failing over to a secondary region in case of disaster. Which cloud characteristic enables this capability?
Global infrastructure
Multiple regions enable cross-region failover for disaster recovery.
Scalability
Why wrong: Scalability handles demand changes, not geographic failover.
Measured service
Why wrong: Measured service refers to usage tracking and billing.
Resource pooling
Why wrong: Resource pooling is multi-tenancy, not disaster recovery.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Global infrastructure
Global infrastructure refers to the distributed network of data centers across multiple geographic regions. By deploying resources in a secondary region, an organization can fail over to that region during a disaster, ensuring business continuity. This capability is unique to the cloud's global footprint, not to other characteristics like scalability or measured service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Global infrastructure
Why this is correct
Multiple regions enable cross-region failover for disaster recovery.
Related concept

Scalability
Why it's wrong here
Scalability handles demand changes, not geographic failover.
Measured service
Why it's wrong here
Measured service refers to usage tracking and billing.
Resource pooling
Why it's wrong here
Resource pooling is multi-tenancy, not disaster recovery.
Common exam traps
Google Cloud often tests the misconception that scalability or resource pooling alone can provide disaster recovery, but failover requires the physical presence of infrastructure in separate geographic regions, which is a function of global infrastructure.
Detailed technical explanation
Under the hood, global infrastructure relies on a provider's backbone network connecting multiple availability zones within regions, often using technologies like BGP for route propagation and DNS-based traffic management (e.g., AWS Route 53 or Azure Traffic Manager) to redirect traffic during failover. In a real-world scenario, an organization might configure active-passive failover using health checks and automated DNS updates, ensuring RTO and RPO targets are met. This requires careful planning of data replication (e.g., synchronous vs. asynchronous) and network latency considerations.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
