CLF-C02 Cloud Concepts Practice Question
A financial services firm must prove to auditors that its AWS environment is designed to avoid single points of failure and that it can recover from component outages without manual intervention. Which AWS Cloud concept most directly addresses this requirement?
⚠ Common exam trap
The trap here is choosing elasticity because it sounds like resilience, when elasticity is about matching capacity to demand, not about eliminating single points of failure.

Correct answer & explanation
✓
High availability, by designing redundant components that fail over automatically
High availability is the architectural principle of removing single points of failure through redundant components and automated failover. It is the concept that directly answers an auditor asking for evidence that outages of individual components will not take down the workload and that recovery happens without manual action. Elasticity, the shared responsibility model, and economies of scale address different concerns.
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, which lower the cost of AWS services over time
Why it's wrong here
Economies of scale describe how AWS aggregates demand across many customers to lower prices, which is a cost benefit rather than a resilience property. It says nothing about redundancy, failover, or single points of failure. Presenting this concept to auditors would not address their concern about component outages and automatic recovery, so it is the wrong concept for this requirement.
- ✓
High availability, by designing redundant components that fail over automatically
Why this is correct
High availability is the design principle of eliminating single points of failure by deploying redundant components and configuring automatic failover. This directly satisfies the auditors' requirement that the environment avoid single points of failure and recover from component outages without manual intervention. Multi-AZ deployments, load balancing, and health-check-based failover are typical implementations of this concept.
- ✗
Elasticity, by automatically scaling capacity up and down with demand
Why it's wrong here
Elasticity focuses on matching capacity to changing demand, which improves cost efficiency and performance but does not by itself eliminate single points of failure. A workload could scale elastically yet still depend on one database or one Availability Zone. Auditors asking for evidence of fault tolerance and automatic recovery need a design principle that explicitly addresses redundancy and failure handling, not demand-based scaling.
- ✗
The AWS shared responsibility model, which divides security duties
Why it's wrong here
The shared responsibility model defines which security tasks belong to AWS and which belong to the customer, such as patching guest operating systems versus securing physical facilities. It is essential for security and compliance discussions, but it does not describe redundancy or automatic failure recovery. Relying on it would not demonstrate that the architecture lacks single points of failure, so it does not meet the auditors' specific request.
