Not so sure about that, seems like there could be other factors involved.

Wait, can a single large number really crash the whole service?

Definitely a buffer overrun, that’s what happens with large inputs!

I think it's more of an exception generation attack.

Sounds like a classic buffer overrun attack to me.

I don't recall much about XML parser attacks in this context, so I’m leaning towards option A as the most likely answer.

I practiced a similar question where a service crashed due to input validation issues. It feels like this is also a buffer overrun, but I could be wrong.

I'm not entirely sure, but I remember something about exception generation attacks. Could this be related to how the service handles unexpected input?

I think this might be a buffer overrun attack since the large numeric value could exceed the buffer size and cause a crash.

I'm a bit confused by this question. The options seem to overlap a bit, and I'm not entirely familiar with the Vlocity platform. I'll have to review my notes and try to eliminate the options that don't seem as relevant.

I'm not entirely sure about this one. The information seems straightforward, but I want to double-check my understanding before selecting an answer.

I'm pretty sure the answer is B. The URI, or Uniform Resource Identifier, is used to identify the specific file that the HTTP GET request is targeting.
