Title: He's not Todd Lammle
Review: I was previously CCNA certified when I took this test, thank goodness. I was hooked on the Sybex series because of Todd Lammle, what a great author he is. This book was not clear, even inacurate. Level two datagrams are called frames, not packets. Packets exist at layer 3 of the OSI model. This error kept popping up, if I didn't know the real answer I would have missed the question on the test that related to this. The book did not discuss token ring well enough for me, as I have never used it. I would suggest finding another book or going through a Cisco Networking Acadamy, you can get both your CCNA and your Network + certification that way. I felt like I wasted money on this book even though I passed the test the first time. Look elsewereAnd remember that layer 3 datagrams are called packets, layer 2 datagrams are frames...hence frame relay which is a layer 2 technology and packet filtering capabilities of routers which operate at layer 3.
Is the review positive or negative?
