I'm surprised "bonged" is included, thought it wouldn't match!

Wait, does "bonged" even count?

The regex matches "bang", "bong", and "bung".

I’m confused about the "n?" part. Does that mean it can match with or without the "n"? If so, I think it should include "bang" and "bung" for sure.

I feel like "bonged" might be tricky because of the extra "ed" at the end. I’m leaning towards option A or B.

I remember practicing a similar question where we had to identify matches based on regex patterns. I think "bang" and "bong" are definitely in there.

I think the regex matches "bang", "bong", and "bung", but I'm not sure if "bonged" fits since it has an extra letter.

I'm a little confused by the RESTCONF reference. I'll need to make sure I understand how that protocol works in order to answer this question correctly.

Software-defined networking seems like the most likely answer here. It allows for centralized policy management while being independent of the underlying hardware.

Okay, I remember learning about the spectroscopic ratio in class. I think it has to do with the number of channels or wavelengths supported. Let me review my notes.
