I always mix them up, but I think greedy is the default, right?

It's definitely about the amount matched, not speed.

Greedy matches as much as possible, lazy matches as little as needed.

I thought greedy and lazy were about how the regex engine processes the input, but I don't remember which answer that aligns with.

I feel like this is similar to a practice question we did on regex quantifiers, but I can't recall the exact definitions.

I remember practicing a question about quantifiers, and I think greedy means it tries to match as much as possible, while lazy matches as little as possible.

I think greedy vs. lazy refers to how much of the input the regex tries to match, but I'm not sure which option that relates to.

Okay, I've got this. Greedy vs. lazy refers to whether the pattern quantifiers will try to match as much as possible (greedy) or as little as possible (lazy). That's the key distinction here. I feel good about this one.

Hmm, I'm a bit confused on this one. I know greedy and lazy have to do with the pattern matching, but I can't quite remember the exact difference. I'll have to think this through carefully.

I'm pretty sure this has to do with how the pattern quantifiers like * and + behave. I think greedy means they'll match as much as possible, while lazy means they'll match as little as possible.

Wait, I thought greedy vs. lazy had to do with how strict the pattern has to be, not the quantifier behavior. Hmm, I better review my regex notes before answering this.

Okay, I've got this. The feature that allows the network to wait before notifying the routing protocol of a change is the SPF hold time. That's the one that controls the delay before the routing protocol is informed of a topology change. I'm confident this is the right answer.

Alright, I've got a strategy here. I'll start by selecting the individual user option, since that's a pretty standard way to grant access. Then I'll think through the other grouping options they might have and select those as well.

Hmm, I'm a bit confused about the floating IP addresses. Do those come into play here, or is the question just focused on the self IPs and virtual server IP?

Alright, time to put on my regex detective hat. I reckon D is the answer - the pattern quantifiers should know when to stop at whitespace, right?
