Thanks to those folks here who took the time to answer my questions. All the hard work has finally paid off with a CCNP. Hopefully it's enough to get a job out in Goleta, we'll see.
Took the 642-891, because I love a challenge.
Here's one that didn't make a whole lot of sense to me:
Using CIDR, what supernet can summarize the Public Class B range?
(Yes, it did say "the")
A) /8 B) /12 C) /16 D) /24
Well, B seems like it has to be the answer as I was looking for /2. I'm guessing they meant "a class B range," not "the Class B range," which isn't something you'd ever want to summarize. Their mistake or mine?
