Half duplex won't work for monitoring, just saying.

I agree, it captures all traffic on the network.

Wait, is promiscuous mode really the best choice?

Full duplex is great, but not for this purpose!

Audit mode sounds unfamiliar; I don't recall it being mentioned in the context of traffic monitoring.

Half duplex and full duplex are more about communication direction, right? I don't think they help with monitoring.

I practiced a similar question where we had to choose between different modes, and I feel like promiscuous mode was the answer there too.

I think I remember that for monitoring traffic, the promiscuous mode is usually the right choice, but I'm not entirely sure.

I'm pretty confident the answer is Promiscuous mode. That's the standard configuration for network monitoring tools like NIDS to capture all network traffic, including traffic not directly addressed to the monitoring device.

Okay, let me think this through. If the goal is to monitor network traffic, then I believe the correct answer is Full Duplex mode. This allows the network interface card to transmit and receive data simultaneously, which is important for effective network monitoring.

Wait, I'm a bit confused. Isn't Promiscuous mode used for network sniffing and packet capture? I'm not sure if that's the right approach for monitoring network traffic with an NIDS.

Hmm, this seems straightforward. I think the answer is Promiscuous mode, since that allows the network interface card to capture all network traffic for monitoring.

Half duplex? What is this, the stone age? Come on, guys, let's join the 21st century and go Promiscuous. Gotta catch 'em all, Pokémon-style!

Hmm, Audit mode, huh? Sounds like we're going for a more professional approach here. I dig it, keeps things nice and tidy.

Promiscuous mode all the way! Eavesdropping on network traffic has never been so much fun. Can't wait to catch some juicy conversations.

Ah, the classic NIDS dilemma! Gotta love those networking terms. I'm voting for Promiscuous mode - sounds like a wild party, but it gets the job done, am I right?
