Cisco 400-007 Exam - Topic 2 Question 81 Discussion

A bank recently had their security compromised during an initial key exchange between devices using a symmetric cryptography algorithm, and as a result the key was revealed/leaked. Going forward, they want to ensure that key exchanges are performed using asymmetric cryptography algorithms. Which algorithm offers the desired functionality?
D) Diffie-Hellman
A) AES
B) RSA
C) RC4

I agree, but Diffie-Hellman is also a solid option for key exchange.

I think RSA is the best choice here. It’s widely used for secure key exchanges.

Wait, can RSA really handle this? Sounds risky.

AES is symmetric, so it won't work here.

I thought Diffie-Hellman was the go-to for this?

I recall that RSA is often used for encrypting keys, but I wonder if it directly applies to the key exchange scenario mentioned in the question.

AES is definitely symmetric, so it can't be the answer. I feel like I might confuse RSA and Diffie-Hellman under pressure.

I think Diffie-Hellman is specifically designed for key exchange, so it might be the right answer. I practiced a similar question on that.

I remember studying that asymmetric algorithms like RSA are used for secure key exchanges, but I'm not entirely sure if it's the best choice here.
