I feel like I might have seen this in a study guide, but I can't recall if 'docker inspect' is the right command for this purpose.

I'm a bit confused; I thought 'docker inspect' was more for inspecting individual containers or images, not listing nodes.

I remember practicing a similar question, and I think the correct command is actually 'docker node ls' for listing nodes.

I think the command is supposed to show details about nodes, but I'm not sure if it lists them all.

I've got this! The three interface deployment methods are Layer 2, Virtual Wire, and Layer 3. I'm feeling good about this answer.

Okay, let me think this through. I know compliance is related to security, so I'm guessing it would be under the Defend section. I'll go with Defend > Compliance.

Ha! 'docker inspect nodes'? Sounds like something straight out of a 'Docker for Dummies' book. I'm going with 'B' on this one.

Nope, 'docker inspect nodes' won't do the trick. I bet the exam writer is a former stand-up comedian, trying to slip in a little comedy gold with these questions.
