MCSE Training Kit Book Wrong...

| On pages 29-30 of the Network Infrastructure Administration book under the "Internet Protocol (IP)" heading it states:
"Although TCP separates data into discrete <WRONG>packets</WRONG> and is responsible for guaranteeing their delivery, IP does the actual delivery. At the IP Layer, each incoming or outgoing packet is referred to as a datagram. The IP datagram fields in the following table are added to the header when a packet is <WRONG>passed up</WRONG> from the Network Interface Layer.
....<on down a bit>
Time to Live (TTL): Designates the number of <WRONG>seconds</WRONG> a datagram is allowed to spend in transport before it's discarded. This prevents packets from endlessly looping around an internetwork. Each router that forwards the packet decrements the TTL by one. The default TTL in Windows 2000 is 128 seconds. "
ERROR #1: The Protocol Data Unit (PDU) for TCP is 'segment' NOT 'packet.'
ERROR #2: The IP Headers are added when data is being sent down the stack to the wire NOT when it is passed up from the Network Interface Layer. The header is stripped on the way up.
ERROR #3: The Time to Live (TTL) does NOT designate ANYTHING measured in 'seconds' but in 'hops'.
NOTE: All of these items ARE described correctly in the Win 2k Server Resource Kit.
Does it bug anybody else? Also this is the thinnest book in the training kit and yet the hardest test?
Okay I'm a picky $#&$#! | |

| I've been there...they didn't have it listed in the errata. I left a feedback message about it. | |

| Those are some really serious errors. Whatever happened to "Proofreading"? | |

Yes, I noticed that as well. I have the MS press kits for 70-210, 70-215, 70-217, 70-218, 70-219 and 70-224 and they are all big books. The 70-216 is 1/2 the size of any of the other books, yet is made out to be a killer test. How can you have a book so small, yet be such an intimidating exam? |
