Show Suggested Answer

Suggested Answer: D

https://en.wikipedia.org/wiki/Modulo_operation

The modulo operation returns the remainder or signed remainder of a division, after one number is divided by another (called the modulus of the operation).

Given two positive numbers a and n, a modulo n (abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor. The modulo operation is to be distinguished from the symbol mod, which refers to the modulus (or divisor) one is operating from.

For example, the expression '5 mod 2' would evaluate to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while '9 mod 3' would evaluate to 0, because the division of 9 by 3 has a quotient of 3 and a remainder of 0; there is nothing to subtract from 9 after multiplying 3 times 3.

I’m really unsure about this one. I thought mod was just the number itself if it’s less than the divisor, but that doesn’t seem to apply here.

I recall that when you do 8 mod 3, you subtract multiples of 3 from 8. So, I think the answer is 2.

I’m not entirely sure, but I feel like I practiced a similar question where the answer was 1. Could it be that?

I think the mod operation gives the remainder, so I remember that 8 divided by 3 is 2 with a remainder of 2.

I'm pretty confident I know the answer to this one. The two basic types of interviews are structured and unstructured.

I feel confident about this one. The key is to focus on the specific OSPF features that are configured in Cisco FMC and propagated to FTD.

Ah, I think I got it! The "except" part means the answer is the one thing that's not considered a hardening technique. Removing antimalware would actually make the system less secure, so that's gotta be the right answer. Nice, I feel good about this one.
