Step 3 (describing how to set up a hyperterminal session) says:"The default values (2400bps and no flow control) will not work; The sentence should read "the default values (2400bps and flow control hardware) will not work;..."

5th question, 2nd line should read, "...more than about...." instead of, "...more then about..."

Question # 16, The question asks to choose 3. Should ask you to choose 4.

The very last paragraph on that page reads "The hex answer would be B5, since 1011 converts to B and 1010 converts to 5 in hex value." This is incorrect. 5 in hex is 0101.

This should be raised 2^32...."..0 - gives you 232..." 2 to the 32 power
Page 87
Just below middle of the page reads as follows; "Each inique Class C network has one byte to use for node addresses. This leads to 28 or 256..." It should read "2 to the 8th power", not 28.

FAQ
I am confused on the book CCNA Study Guide Fourth Edition. Specifically chapter 3 on IP addressing where the first subnet is skipped and also the last subnet on the class C examples. Also I cannot find a clear example of why to find the subnets (networks) is minus 2. On the example, page 110 for a /27 # of subnets says 6, 2(3) -2. When clearly you can have 8 in that class. Please explain.
response
On the Cisco exams, cisco uses a -2 after you calculate your subnets. You do not have to do this in production, but on the Cisco exams you do.

Example 7B -
I have a question on the example (#7B) on page 119 of the CCNA Study
> guide (exam 640-801). It says you can use 0 or 224 subnets as long
> as the third octet does not show a value of 0 or 255. In the example
> is shows subnets 0.32 thru 0.224 as valid. Is this correct? Thanks
> in advance.
response..
what I wrote is no longer true as of a month ago or so.
The zero and 255 subnets are now valid on the Cisco exams.
They have always been valid on Cisco's gear, they just didn't test on it,
now they do.
Cheers!

Figure 3.3, the subnet off of router Lab_D should be 192.168.1.48/28, not 45/28.
Page 129
The table on the bottom left should match the numbers in figure 3.5. Luckily,
technically, this doesn't change anything as the block sizes are still valid
Figure 3.6 should be 192.168.10.0, not 192.16.10.0.
Please fix the chart on the bottom
of figure 3.6 to match the host amounts listed in figure 3.5. Page 130
see detailed description
> p.130 in first paragraph under Fig 3.7 states "Figure 3.7 shows a

>
> p.130 Figure 3.7 (and p.131 Class C Network Table at bottom left shows
> this) actually has "... one of 32, five of 16 ..."
Yes, luckily the text is the problem and not any figures here. Fix the
sentence to say "one of 32, five of 16 and three of 4". Page 133
Figure 3.9 shows 192.168.1.97.27 for Lab_A interface S0/0 should read "192.168.1.97/27" for Lab_A interface S0/0

5th line should read, "This chapter provided you with an important understanding..."

Lab_C(config)#ip route 192.168.20.0 255.255.255.0 172.16.40.1 The exit interface IP should be 192.168.40.1 not 172.16.40.1
Page 221
Part of the output of "Ping 192.168.50.1" is mistakenly to "172.16.50.1", it should be "192.168.50.1" Same thing happen to the next command "ping 192.168.10.1", please change the output part of "Echos to 172.16.10.1" to "Echos to 192.16.10.1"
In the "sh ip route" output at the top of the page one line shows as "S 192.168.20.0 [1/0[ via 192.168.40.1" and the "[1/0[" should be "[1/0]".
Page 234
The "via 172.16.40.2" should be "via 192.168.40.2" and the "via 172.16.20.1" should be via 192.168.20.1"
In the Lab_C sh ip route output serial interface:"R 192.168.20.0 [120/1] via 192.168.40.1, 00:00:26, Serial0/ "(should be"... Serial0/0")
Page 238
The note on page 238 reads 172.16.x.y but should read 192.168.x.y. Also,172.16.0.0/24 should read with a /12, after the other correction. Page 243
The output shows serial0/0 (172.16.20.2). It should be 192.168.20.2 not 172.16.20.2
Page 244
5th line should read: Serial0/1 (192.168.40.1) rather than Serial0/1 (172.16.40.1)

The static route configuration for the router 2621A should use the next hop address of 172.16.10.2 instead of 172.16.10.1

change the routing table output for the following
C 192.168.40.0/24 is directly connected, Serial0 (should be Serial1)
R 10.0.0.0/8 [120/1] via 192.168.20.1, 00:00:16, Serial1 (should be Serial0)
R 192.168.3.0/24 [120/2] via 192.168.20.1,00:00:16, Serial1
(should be Serial0)
