Your question is Symmetric vs Asymmetric Crypto. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the practical differences between symmetric and asymmetric cryptography, and when you would use each.
Cover how the keys are generated and used, the performance and key-management trade-offs, and how both approaches commonly work together in protocols such as TLS. Keep the answer focused on practical security engineering decisions rather than mathematical derivations.
