Answer Example

I design fault-tolerant systems by incorporating redundancy, fail-safe mechanisms, and error correction techniques. For example, in an aerospace control system, I implemented dual-redundant power supplies and error-checking protocols like CRC (Cyclic Redundancy Check) to ensure continuous operation during faults. I also conducted fault injection testing to verify system resilience. This approach ensures reliability and safety in critical environments.
