D is definitely wrong, it can work with public key cryptography too!

B seems off, ECC isn't a default for IPSec, right?

C is spot on, it does support both modes!

I thought IPSec could use more than just secret key cryptography?

A is correct, HMAC-MD5 and HMAC-SHA-1 are standard.

C seems accurate since IPSec does support both Tunnel and Transport modes, but I’m unsure about D.

I'm not entirely sure about B; I remember something about DES, but I thought AES was more common now.

I think A is correct because HMAC-MD5 and HMAC-SHA-1 are commonly used hashing protocols in IPSec.

D sounds off to me; I recall that IPSec can work with both symmetric and asymmetric cryptography, so it shouldn't be limited to just secret key cryptography.

Okay, let me think this through. The key is to cover the requirement REQ-SEL-4, which is about testing wrong numbers of bottles. Option C seems to do that by checking the error message, so I think that's the best choice here.

The separate account is meant to segregate the assets and liabilities for certain products, so the funds can't be used for the company's general operations. I'm pretty sure option D is the correct answer here.

I'm not entirely sure about the actual contribution ratio being lower… does that affect our variance significantly? It feels tricky to figure out.
