CLF-C02 Cloud Concepts Practice Question
A startup currently runs all of its production workloads in a single AWS Region. The CTO wants to reduce the risk of a prolonged outage caused by a large-scale natural disaster affecting that Region. Which AWS Cloud concept should the team implement to meet this goal?
⚠ Common exam trap
Watch out — candidates often confuse high availability across Availability Zones inside one Region with true disaster recovery across separate AWS Regions.
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
✓
Deploy the workloads to multiple AWS Regions and use a multi-Region architecture
AWS Regions are isolated geographic areas, so an event that disables one Region generally does not affect others. To survive a large-scale disaster, the workload must run in more than one Region with appropriate routing and data replication. Availability Zones provide resilience inside a single Region but cannot protect against the loss of that entire Region.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy the workloads to multiple AWS Regions and use a multi-Region architecture
Why this is correct
AWS Regions are geographically separate and isolated from one another, so a disaster affecting one Region does not affect another. By deploying the workload into at least two Regions and routing users appropriately, the startup can continue serving traffic even if an entire Region is lost, which directly addresses the CTO's requirement to survive a large-scale regional disaster.
- ✗
Purchase a higher-tier AWS Support plan to guarantee Regional failover
Why it's wrong here
AWS Support plans provide access to technical account managers, faster response times, and proactive guidance, but they do not architect or operate failover for customer workloads. No support tier can prevent a natural disaster from taking a Region offline. The startup must design its own multi-Region deployment; a support plan alone cannot deliver the resilience the CTO is asking for.
- ✗
Deploy the workloads across multiple Availability Zones within the same Region
Why it's wrong here
Multiple Availability Zones protect against the failure of a single data center or isolated infrastructure component inside one Region, but they do not help when an entire Region becomes unavailable. A large-scale natural disaster can affect every Availability Zone in that Region, so this approach would not satisfy the CTO's stated goal of surviving a Region-level event.
- ✗
Enable AWS Shield Advanced on the account to protect the Region from disasters
Why it's wrong here
AWS Shield Advanced is a managed distributed denial-of-service protection service that defends applications against network and application-layer attacks. It has no role in mitigating natural disasters or Regional outages. Enabling it would improve security posture against malicious traffic, but it would leave the workload fully dependent on a single Region and therefore fail to meet the CTO's availability goal.
