Which architecture is most susceptible to single points of failure due to centralization?

• A. Edge computing
• B. Decentralized computing architecture
• C. Distributed computing architecture
• D. Centralized computing architecture

Answer: (D)

Centralized computing concentrates control and resources in a single hub. Because those functions rely on one central component, any failure of that hub—whether due to hardware, software, or security issues—can bring down the entire system. That creates a single point of failure inherent to centralization. Edge computing, by processing data closer to the source, reduces dependence on a distant central node and can continue local operations even if the core is unavailable. Decentralized architectures distribute control across multiple independent nodes, so no single node failure collapses the whole system. Distributed computing spreads tasks across many machines with redundancy, providing even more resilience. So the architecture that is most susceptible to a single point of failure because of centralization is the centralized computing architecture.
