Practice Example #2A Last column of table, all IPs should be 10.255.x.x not 10.0.x.x
Response...

Yes, this is correct.
After the ... in this practice example #2A on page 129, here is what it
should be

10.255.240.0
10.255.240.1
10.255.255.254
10.255.255.255

Chapter 3 Question 11 - Updated 04/20/05
Support, the new question and explanation is after the old one - the
question, answer and explanations were wrong somehow. Please replace this
question in the next printing:

____________________________________________________________

F. 110.68.12.128
Answer: B, C, E.
New explanation:
A Class A network address with a /22 is 255.255.252.0. The subnets
in the third octet are 0, 4, 8, 12, etc. The network address in the
question is 110.68.4.0, with a broadcast of 110.68.7.255, since the
next subnet is 110.68.8.0. Answers B, C, and E are correct host IDs.

This is really an issue with your revised solution to an errata
problem already reported, regarding Question 11 in Chapter 3, pages

Page 187

The second command (line) from the bottom of the page should read “Router(config-line)#exit” instead of just Router(config)#exit

Page 189

"Router(Config)-if)#" should be "Router(Config-if)#"

Page 213

Question 11: In the multiple choice questions B and D, the router prompt should be "SFRouter", not "SFRemote"

Page 218

Answer 11 should be C, not D

Page 235

Fourth line down should be 192.168, not 172.16

Page 236

End of first paragraph should be 192.168, not 172.16

Page 271

Line 3-4 Should read “debug ip rip” not “debug ip route”

Page 275

The text reads: "Table 5.3 shows our IP addresses for each router..." That should read Table 5.5.

Page 276

Step 1 reads, "...The 2621A router fa0/0 interface has an ip address of 172.16.10.2/24, and the 2501A Ethernet 0 interface is 172.16.10.1/24." This part of the question contradcits table 5.5.

response..
Yes, the static routes in step one should all go to 172.16.10.2

Page 282

Question #7, answer A. should read:
"RouterC will use an ICMP to inform HostA that HostC cannot be reached."

Page 326

4 lines from bottom. IP addresses should be 192.168.10.64 through 192.168.10.95

Page 517

Answer numbering is incorrect

The answer to question 3 (Written Lab 10) should be "access-list 10 deny host 192.168.15.5" where the IP address of the host is different.

Page 570

Q12. The command variables 180 and 40% have been transposed.

Chapter 4 -Enabling Passwords

response ..
It can be either way, as mentioned. Cisco asks it both ways, which is why I
show it both ways. The latest IOS only supports the login after the
password.

Page 135,137,139

On pages 135 and 137, the tables at the top of the page (From left to right: Subnet, Mask, Subnets, Hosts, Block) are incorrect in the Subnets column. It seems as though each number is listed as two less than it should be. For example: A subnet with mask 192 is listed as having only 2 available subnets, even though the block size is 64. As the author stated on page 136, "With a block size of 64, you can only have four networks, and so on, ..."

Response..

Yes, those tables were not updated in accordance with the ip subnet-zero
rule, so the 192 mask would provide four subnets, etc.

Number of subnets needs to be +2

Right now, they are 2, 6, 14, 30, 62…..please change to 4, 8, 16, 32 and 64.

This is for both the CCNA Study Guide, 5th Edition (0782143911) and CCNA Study Guide, Deluxe Edition (078214392X).

Page 155, Question 11

Which of the following IP addresses fall into the CIDR block of 110.68.4.0/22? (Choose three.)

A. 110.68.8.32
B. 110.68.7.64
C. 110.68.6.255
D. 110.68.3.254
E. 110.68.5.128
F. 110.68.12.128

Answer: B, C, E.
A Class A network address with a /22 is 255.255.252.0. The subnets in the third octet are 0, 4, 8, 12, etc. The network address in the question is 110.68.4.0, with a broadcast of 110.68.7.255, since the next subnet is 110.68.8.0. Answers B, C, and E are correct host IDs.

241Page 241
On the last sentence of the second to the last paragraph of page 241 which reads: "Router Lab_A will only send packets to the 192.168.20.2 interface of Lab_A." should be "Router Lab_A will only send packets to the 192.168.20.2 interface of Lab_B." (last word word on this sentence should be changed from Lab_A to Lab_B).
