Yup, C is definitely the asymmetric one!

Blowfish and RC4 are symmetric, right?

Wait, isn't Diffie-Hellman just for key exchange?

Totally agree, it's a key exchange method!

C is the right answer, Diffie-Hellman is asymmetric.

I definitely recall that Diffie-Hellman is used for key exchange, which usually involves asymmetric encryption, so I’m leaning towards that option.

I’m a bit confused; I thought RC5 was also asymmetric, but now I’m not so sure.

I practiced a similar question last week, and I believe Blowfish and RC4 are symmetric algorithms, so they can't be the answer.

I think I remember that Diffie-Hellman is related to asymmetric encryption, but I'm not entirely sure if it's the only one here.

I've got this! Asymmetric encryption uses a public/private key pair, so the answer has to be Diffie-Hellman. That's the only asymmetric algorithm listed.

I'm a bit confused on this one. I'll need to review my notes on the different encryption algorithms to make sure I understand the distinctions.

Okay, I know Blowfish and RC5 are symmetric ciphers, so those are out. Diffie-Hellman is a key exchange protocol, not an encryption algorithm. That leaves RC4 as the only asymmetric option.

Hmm, this looks like a tricky one. I'll need to think carefully about the differences between symmetric and asymmetric encryption algorithms.

Component integration and test, that's definitely part of the Vee model. I'm a little less sure about the other options, though. Gotta be careful here.

I keep mixing up "show crypto isakmp sa" and "show crypto ipsec sa" — not sure which one is more relevant for NHRP problems!

Okay, let's see. Service Factor and Service Level seem like the most likely options that would affect both. I'll start there and see if I can eliminate the other choices.

The wording of the question is a bit technical, but I think I can narrow it down by considering the different disjoint attributes listed. I'll make my best guess and move on.

RC4 is a classic symmetric cipher, so that's definitely not the right answer. Gotta be Diffie-Hellman!
