I am studying from the following: -CBT Nuggets CCNA -Cisco CCNA Exam Library, 3rd Edition -CCNA Study Guide, from Sybex (T Lammie), 6th edition Today, I read the 1st chapter from the Cisco book. Pretty straight ahead and stuff that was already covered from studying from the Network+. I have a feeling it won't be straight ahead like this for the rest of the book.

A switch that can do layer 3 is called a multi-layer switch. You will learn more about that in CCNP I believe, because they cover MPLS and stuff like that.Multilayer switch - Wikipedia, the free encyclopedia There's no real difference, it just depends on how you design your network. Switches operate at layer 2 unless they are multilayer switches as mentioned before.Hierarchical internetworking model - Wikipedia, the free encyclopedia that's basically a quick summary of the hierarchial model, basically core layer has the most powerful processing equipment, because it is the high speed backbone of the network. It also provides redundancy in case of a failure at the top of the network, which is pretty important in large networks. The distribution is the "smart" layer where all the routing and filtering happen. The access layer is the end devices on the network. If you look at wikipedia it will tell you that Layer 3 switches can be found on the access layer if they are so desired. So basically I hope that answers your question, you can find Layer 3 switches in the core, distribution, or access layers.
Core Layer is literally the core of the network. At the top of the hierarchy, the core layer is responsible for transporting large amounts of traffic both reliably and quickly. The core is likely to see large volumes of traffic, so spped and latency are driving concerns here.
Sometimes referred to as the workgroup layer and is the communication point between the access layer and the core. The primary functions of the distribution layer are to provide routing, filtering and WAN access and to determine how packets can access the core, if needed. The distribution layer is the place to implement policies for the network
The access layer control user and workgroup access to internetwork resources. The access layer is sometimes referred to as the desktop layer
