I had no idea it was that low in the OSI model!

I definitely recall that sniffers are related to the Data Link layer, but I wonder if they can also interact with the Network layer in some way.

I’m a bit confused. I thought sniffers worked at the Network layer, but now I’m second-guessing myself after reviewing the layers.

I remember practicing a question about OSI layers, and I think sniffers capture packets at the Data Link layer. That seems to fit.

I think sniffers operate at the Data Link layer, but I’m not completely sure. It could also be the Network layer, right?

I remember learning about sniffers in my networking class. If I recall correctly, they operate at the data link layer to capture and analyze the raw data frames being transmitted on the network. I'll select option D.

The network layer seems like the most logical choice here, since a sniffer is used to capture and analyze network traffic. I'll go with option A.

Hmm, I'm a bit confused on this one. I know a sniffer is used for network monitoring, but I'm not sure which layer it operates in. I'll have to think this through carefully.

Modeling and simulation could be a good option too. It can help Frances simulate different risk scenarios and their effects on the project, which could give her a clearer picture of the most critical risks.

Aligning projects to strategy sounds like a key COE function, so I'm leaning towards option D.

If a sniffer is a tool to sniff out network traffic, it must be operating at the lowest layer, the Data Link layer. D is the way to go!

This is a tricky one. I'm going to go with C, the Presentation layer, because that's where all the data gets formatted, right?

Wait, isn't a sniffer supposed to be a hacker tool? I'm pretty sure it's in the Network layer, so A must be the right answer.

I'm not sure, but I think it might be the Network layer because it deals with routing and forwarding of data.
