Network+ Study Guide errata?

[kristini]

Hello... This isn't the right place for this post, but there is no better.

I just bought the _CompTIA Network+ Study Guide_, and although I am enjoying it so far I've found a couple of errors. Typos happen, of course... but what is of concern to me is that there is no mention of this book anywhere here in these forums/on lammle.com, and even the errata pages listed in the textbook are wrong/missing! [The book states "To find up-to-the-minute updates for this chapter, please see www.lammle.com (http://www.lammle.com) or www.sybex.com/go/comptianetwork+."]

Where is the errata for this book? Am I just being impatient, and nothing has been posted yet? Perhaps a page stating such could be posted at the above-mentioned sybex link?

Thanks...

[lammle]

Thanks for writing.
There is no URL or links because there is no errata.
Your posting will be the first.
Ethernet, UTP, can go 328 feet, 100 meters. I accediently wrote 228 feet somehow. Thanks for catching that!
The link will be up this week.
Let me know if you have any other questions.
Cheers!

I too have noticed a number of typos. For the most part they do not seem to prevent understanding of the material. Prior to chapter 8 (where I am now) the biggest confusion I found was in reference to wiring standards 268A (Straight through) and 268B (Crossover) is mistyped as 286A & 286B.

[lammle]

I wouldn't use the words "a lot of typos" as that is a huge book and the documents change a lot of hands before the book gets printed, which can create problems in itself.

Also, since I use Microsoft Word, it has the tendency to change words it "thinks" I meant to write and I don't always catch all those.

I read all my books dozens of time and you can never see your own errors it appears. And, well, I just make typos because I have to write so fast. It's hard not too. :(

With that said, I welcome constructive criticism on this forum, as this is the reason I opened this free, public forum - to help people reading my books connect directly to me and get answers to their questions.

I agree that I typed 586 when I meant to write 568A or 568B. Ironically, 586A and 586B also happen to also be a wiring standard - go figure!

What you need to know is that 568A is a straight through cable and 568B is a cross over cable. The book just went to reprint and I fixed all of these errros. The CompTIA objectives only cover the 568 standards.

Cheers!

I did not mean to be impolite or critical. I have sent 8 or 10 messages to the Wiley web site regarding typos. Should I send any further findings to you hear or continue posting them to the Wiley site?

[lammle]

You weren't being impolite or critical, thank you for your post. The stupid forum made the word "critical" look larger for some reason. Go figure!! :o

I am not sure if I got your corrections or not from Wiley, I probably did.
I know that I fixed a hell of a lot of pages that had 586 instead of 568 listed, amoung other errors.

Please, by all means, send me what you have so I can get them fixed and/or clarify them for you!!

Cheers!

Thank you for accepting feedback so graciously. It will take some time to condense my posts to Wiley but I will get to that as soon as I can. In the mean time I am puzzling over page 280 question 13. I suspect there is a typo in the figure.

The answer on page 284 says that the masks do not match and need to be changed to 255.255.255.0, but the masks in the figure DO match. Both read 255.255.255.240.

The book, PDF and Test engine all contain the same apparent error.

The subnets do not match, wiht a 240 mask, the hosts are in different subnets, so the best answer, given the answers we can choose from is that the masks are wrong and were meant to be /24's. That is the only way those hosts can communicate.

I see. I guess I did not read the and understand the question and answer correctly. I did not think of them as being on different subnets. Thank you.

The following is a compilation of the questions I posted on the Wiley site. First let me apologize for the extreme length of the following. Apparently I am very verbose in my questions. I am only trying to be clear and complete, but I do seem to go on a bit. Second I want to apologize if some of my words seem harsh, I was frustrated at the time of the posts and was not receiving what I had thought were useful responses. I have edited some of the posts below, but not most.

What layer 4 protocol is used for the a Telnet connection, and what is the default port number?
A) IP,6
B) TCP, 21
C) UDP, 23
D) ICMP, 21
E) TCP, 23

In the book and the PDF, Page 211 says the answer is E) Telnet and correctly explains that TCP at the Transport layer with the default por number 23.
However the test engine on the CD says B) TCP, 21
but explains Telnet uses TCP at the Transport layer with a default port number of 23.

I got your response on this one through the Wiley site stating that this was a dyslexic error and will be corrected. So I will not quote it all here.

However I am still unclear on one detail. Is there a 586 standard in addition to the 568 standard.

Question 17
says:
What layer in the IP stack is equivalent to the Transport layer of the OSI model?
A. Application
B. Host-to-Host
C. Internet
D. Network Access

Page 212
Answer 17
says:
B. The four layers of the IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model.

Page 180
Note
says:
When the different protocols in the IP stack are discussed, the layers of the OSI and DoD models are interchangeable.

Page 192
contains the term IP Stack in reference to UDP

But apart from the answer on page 212, there is nothing in chapter 6 that claims that the IP stack is actual called the DoD model. Based on having read the chapter and done a fair bit of research on the internet, the only place that states that the "IP stack" is AKA DoD model.
According to my understanding of the book so far, IP is in layer 3, (the Network layer of the OSI model and the Internet layer of the DoD model) and not a description of the model itself.

As a result I would think that Question 17 should read:
What layer of the DoD model is equivalent to the Transport layer of the OSI model?
Answer: Host-to-Host

If my understanding is flawed, please explain why, and explain the IP stack.
Thank you for your time and attention.

P.S.The question in the test engine on the CD is worded and answered the same way.

Question 3
Says:
What two well-known port numbers does a DNS server use?
The answer on page 213 says:
A DNS server uses TCP port 53 for zone transfers and UDP port 53 for name resolutions.

Also
Page 210
Question 20
Says:
Which of the following protocols uses both TCP and UDP?
A. FTP
B. SMTP
C. Telnet
D. DNS
The answer on Page 212 says:
DNS uses TCP for zone exchanges between servers and UDP when a client is trying to resolve a hostname to an IP address.

Page 188 talks about DNS but does not mention "TCP" or "UDP", nor does it relate them to "Zone Transfers" or "Name Resolution".
Page 191 talks about TCP and says it "resolves hostnames" but does not mention "Zone Transfers". (Remember that the answer to Question 3 says that UDP is for "Name Resolution" and not TCP.)
Page 192 talks about UDP but does not mention "Zone Transfers" or "Name Resolution"
Page 194 does have a chart that lists DNS port 53 under the heading of both TCP and UDP. But does not relate them to "Zone Transfers" or "Name Resolution".
Page 203
Paragraph 4
Last sentence contains the only other reference to DNS that I found in Chapter 6, which says:
"...was discovered through name resolution method at the upper layers __ probably DNS..."
To me this is hardly a declarative statement indicating a true fact, but a simple probability.

Does DNS name resolution use TCP or UDP?

And will you please relay this to the author/publisher so they can clarify this subject before the next printing?

Question 7 says:
What UNIX command is used for terminal emulation in the same way as Telnet is used?

Page 213
Answer 7 says:
The UNIX command rlogin functions similarly to Telnet.

Page 185
Under the heading
Secure Shell (SSH)
The last sentence says:
You can think of it as the new-generation protocol that's now used in place of rsh and rlogin -- even Telent.
Chapter 6 makes no other reference that I can find to rlogin or that it is a Unix command.

The first time the book mentions Unix and rlogin in the same paragraph isn't until
Page 531
Under the heading
rsh
which says :
Like many other legacy commands, remote shell (rsh) originated int he Unix world. It was released as a part of the rlogin package in 1983 with version 4.2BSD. rsh is defined in RFC 1258 with rlogin and runs on TCP port 514.

Question Ticket # 090704-000031


Okay, there is not ONE typo in this area. I can't beleive you typed all this out! I shoudl have you write for me.
This is the way I write. After you go through dozens of examples, the math is implied. If you read it again, it makes sense. Put the important "blah, blah, blah..." back in and it says "we always start at 0. so 256-252= 4, yes, that is true, but I just skip that and say "256-252=0, 4, 8, 12, 16" until we get to our answer.
This is an important chapter and one you just MUST understand.
It seems like you do understand it, well enough to write this. If you read it again, you'll understand "my style", or "voicing" some people may call it.
Cheers!

I believe we agree that I understood what you meant, and as long as the pages read as you intended then I am contented. Tonight I am re-reading subnetting Class C addresses and hopefully tomorrow I will understand better when I read Troubleshooting IP Addressing. As far as writing for you, I will be more than happy to entertain any job offers you have available. :)

Unless I have misunderstood the previous examples there is another typo on
page 263
Subnetting in Your Head: Class B Addresses
3. What subnet and broadcasst address is the IP address 172.16.50.10 255.255.240.0 (/19) a member of?
256 - 224 = 0, 32, 64 (remember, we always start counting at zero). The subnet is 172.16.32.0, and the broadcast must be 172.16.63.25 because 64.0 is the next subnet.

I believe the correct broadcast address should be "172.16.63.255"

By the way the reason that I type things out so completely is because I am trying to make it easier on the reader, assuming that they may not have the book in front of them. I am starting to wonder since you are the author, you may have a well thumbed copy at hand. Then again being the author you may not need to refer to it at all unless someone like me is bugging you over trivial details. What works best for you?

Please let me know at your convenience.

[frankenpaper]

If I have learned what you have taught me in chapter 8, then I must conclude the following is a typo or transcription error.
page 285

192.168.100.66/27. A /27 is 255.255.255.224. The fourth octet is a block size of 32. Count by 32s until you pass the host address of 66. 0, 32, 64. The host is in the 32 subnet, broadcast address fof 63. The valid host range is 33-62.
I believe it should read
192.168.100.66/27. A /27 is 255.255.255.224. The fourth octet is a block size of 32. Count by 32s until you pass the host address of 66. 0, 32, 64, 96. The host is in the 64 subnet, broadcast address fof 95. The valid host range is 65-94.

3rd paragraph
says:
Just because we can, let's look at another example. Based on the output of the next routing table, which interface will a packet with a destination address of 10.10.10.14 be forwarded from?

Surely you meant to. Otherwise it would be like saying who is allowed to write a letter to Santa Clause, based on where they live.

The chapter is about routing, and routing is about where things (packets) go, not where they have been, right? :confused:

I hope you are not taking offense to my pointing out things that I see as problems in your book. I am new to networking and so much of what I read is new information to me. I am learning a great deal but at the same time, I am frustrated when something seems unclear or is not explained. I decided to go for my Net+ in the hope that it would improve help me to find work so I do not plan to give up.

Same with IP routing. It has a destiantion, but it MUST have a source and part of understanding routing is knowing where a packet is coming from as much as knowning where it is trying to go, so nope, no typo.

Unfortantantly, the CD ended up with some damn errors somehow. I don't make the CD, but they take the material from the book and create the CD. How they screwed things up, I have no idea. I actually have the changed I just put in and they are reprinting the book and fixing the CD. I'll post the changed later today. Most are minor such as this one, but they are annoying none the less.

thank you for brining these up. Although they are not all errors that you point out, it does make me stop and make sure that I am explaining every sentence in the best way. Plus, you are finding a lot of minor typos that no one else has found though four editors, so thank you!
I like using the forum because many people who might see these can look them up and find the corrections.

Yes, this is a true typo. I stopped counting too soon for the answer.

[frankenpaper]

I thought I would never figure this out. I am embarrassed to say how much time I spent trying to understand the concept of a public encryption key. I believe I have it now. If I am right, there is a sentence that needs to be updated in the next version of the book.

Please let me know weather I am right or wrong.

Chapter 13
Page 434
Heading Public Key Encryption
Second sentence
says
...It works like this: The sending machine's public key is used to encrypt a message to the receiving machine that it uses to decrypt the message with a private key. It's a one-way communication,...

The sentence seems to be saying that if you were going to send me an encrypted message, then you would use your own public key to encrypt the message then I would us my private key to decrypt it. My current understanding tells me that the original sentence in the book is incorrect.

Shouldn't it read more like:
The sending machine uses the public key, that is published by the receiving machine, to encrypt the message. The encrypted message is then sent to the receiving machine (the one that published the public key that was used to encrypt the message) which then uses it's own private key to decrypt the message.

Another way to put it might be:

Example: My computer publishes my public key to the world. My computer will never tell anyone my private key. If you want to send me a secure message (or file), your computer would use my public key to encrypt your message before you send it to me. My computer will receive your encrypted message, and use my private key to decrypt your message, and then I will read it.

Figure 13.6 seems to support my example, and not the one on page 434.

The reason I find this question odd is because it says both "Choose all that apply." and "All of the above". In the book the reader can overcome the logical conflict but in the test engine on the CD it makes less sense because you can not "choose all that apply" because it only offers radio buttons, not check boxes.

It's just another way to ask questions.
Remember, there were 20 chapters, each with 20 review questions, so that is 400 questions I had to write IN the book.
Then I wrote another 500 flash cards and 1000 bonus questions. Some are on the deluxe edition only, but they all had to be different. Do you know how hard that is? good lord!
So, I had to find interesting and new ways to write questions and that is all this is.

[frankenpaper]

Todd,
Perhaps I was unclear. In the BOOK the questions are fine. They make perfect sense. But on the CD it is not possible to chose more than one answer. The test engine has radio buttons allowing only one choice, where as check boxes allow the reader to select more than one answer. I understand that there is only one correct answer (all of the above). I was trying to point out the way the test engine functions with those two questions. In other words, the questions are fine, the HTML is flawed.

[frankenpaper]

I have started chapter 15 and I wanted to see how close I am to being ready for the big test. So I thought I would give the 50 question Bonus Test 1 from the CD a try. But I ran into 8 questions that seem to need some editing.

I believe the cause of most of these issues are a result of faulty transcription into HTML code. These are things that should have been discovered by editors and proof readers.

Furthermore I do not KNOW that I am right, I only THINK that I am right, because I read your book. I am not trying to attack your work, I am trying to help you to improve the Net+ Kit for the next person who buys the kit to learn the material.

Bonus Exam 1
-----------------
Question 15
You need to check the speed and condition of the signal. Which device should you use?
A. Multimeter
B. Packet analyzer
C. TDR
D. OTDR

The answer says:
A time-domain reflectometer (TDR) is a tool that finds and describes faults in metallic cables like twisted-pair and coax, and can provide information regarding the speed and condition of the signal on the wire. The equivalent device for fiber optic is an time-domain reflectometer (OTDR).
Correct Answer: C

My problem with this question is that it does not specify if we are dealing with copper or fiber. So the reader has to guess what the author meant. Since copper is older, cheaper and more common than fiber one can assume that copper is implied and that fiber would be specified, but but without that assumption the answer D.OTDR would be a correct as well.
-----------------
Question 20
says:
What is the dotted decimal equivalent of: 11000000.10101000.00110011.00001111?
A. 192.168.56.15
B. 192.169.51.15
C. 192.168.128.8
D. 192.168.58.14

And the answer says:
11000000 is 192, 10101000 is 168, 00110011 is 51, and 00001111 is 15.
Correct answer: AB

There should be radio buttons, not check boxes, because only one answer is correct (B).
---------------------
Question 25
Which of the following is a private IP address?
A. 11.255.0.1
B. 172.32.1.1
C. 192.168.255.1
D. 192.169.1.1

The explanation of the answer says:
The private address ranges are 10.0.0.0 through 10.255.255.255, 172.16.0.0 through 172.31.0.0, and 192.168.0.0 through 192.168.255.255.
Correct Answer: C

However pages: lvii, 223, 231, 237, and 238 all agree that the class B private address range is 172.16.0.0 through 172.31.255.255 (not 172.31.0.0).
And since answer B.172.32.1.1 is between 172.16.0.0 and 172.31.255.255 it is also a private address.
--------------------
Question 27
reads:
What is the last point that the local exchange carrier responsibility ends they connect a DCE network to you office?

This sentence (question) seems to awkward to me. I understand that your are getting at the Demarcation point but the words in the question do not make sense to me.

I have been trying to re-write the question while maintaining your original meaning. If I understand your explanation of the DCE, it is located at the ISP not on the customers property. (Ref page 50). And so I am guessing that the term DCE is a typo and needs to be replaced with another term that refers to the demarc itself. If I have understood your teachings properly the MDF is the rack (ref page 84) on which equipment is mounted and the NID is the RJ-45 jack (demarc) that equipment in the rack plugs into. With all of this in mind I offer the following questions as a replacement for question 27.

What is the last point that the local exchange carrier is responsible for the connection to an NID or smart jack in your office?

What is the last point where the local exchange carrier's responsibility ends and your responsibility to connect to the CPE of your begins?

What is the last point that the local exchange carrier's responsibility for the connection to a NID or smart jack ends and your responsibility to connect to the CPE of your begins?

What is the term for the point where the service providers responsibility for a connection to the NID ends, and your responsibility to connect to the CPE begins?

What is the term for the last connection point where the local exchange carrier's responsibility ends and the network administrators responsibility begins?

Question 28
Which of the following techniques would increase the bandwidth transmission by joining together multiple connections into one lgical connection?
A. Firewalls
B. Traffic shaping
C. VLSM
D. Bonding
The explanation says:
Bonding allows you to connect two or more physical connections together and join them together to create one logical connection. This provides more bandwidth on the connection.
Correct Answer: C

However if you choose answer D.Bonding, the test engine will mark the answer wrong because it thinks the correct answer is C.
----------------
Question 35
What is the well-known port number for SMTP?
A. 23
B. 25
C. 443
D. 1023
The well-known port number for SMTP is 25.
Correct Answer: C

The explanation says the correct answer should be B.25, but if you do not pick C.443 the test engine will mark your answer wrong.
---------------
Question 37
Which of the following addresses is allowed onto the Internet?
A. 192.19.168.1
B. 10.168.169.254
C. 172.32.255.0
D. 172.31.12.251
The private address ranges are 10.0.0.0 through 10.255.255.255, 172.16.0.0 through 172.31.0.0, and 192.168.0.0 through 192.168.255.255. None of these addresses are allowed onto the Internet.
Correct Answer C

However answer A 192.19.168.1 is not in a private range and would be allowed on the internet. I think this is a typo. Answer A should probably read 192.168.19.1 which would be a private address.
Also the explanation in the answer is wrong about the Class B range. It should read 172.16.0.0 through 172.31.255.255.
------------
Question 50
Which of the following WAN protocols provides 622Mbps bandwidth?
A. OC-1
B. T3
C. OC-3
D. T4
An Optical carrier 3 (OC-3) has a maximum bandwidth 622Mbps and can be used in wide area networks.
Correct Answer C.

But,
Chapter 16
Page 554
Table 16.2
says that
OC-3 runs at 155.52Mbps
and that
OC-12 runs at 622.08Mbps.

Todd,
Please don't think I am trying to pick on you. I just thought that since the text of the test my need a bit of editing because of some or all of the 8 questions I mentioned in my last post, you might as well take the opportunity to have the more trivial typos corrected at the same time.

--------------
Question 16
The answer says:
By creating a new VLAN for guest access, that will leave your security in tacked, if configured correctly, of course.

I mention this sentence because of the phrase "in tacked". I believe you mean to say "intact" meaning 'untouched' and not 'nailed in'.
-------------------
Question 39
Answer A
reads:
A. 10 feet (33 feet)

I assume you meant:
A. 10 Meters (33 feet)
The correct answer to the question is B so it's not a big deal, but at this point I figure we might as well check the details too.
-------------------
Question 40
Did you intend answers A and C (which are both the wrong answer) to be the same as each other?
-------------------
Question 44
The question refers to a /25 subnet but a typo in the explanation states a /24 subnet.
-------------------
Question 1
Refers to Ping as a program and not a command.
I understand that all commands are programs but...
OK, maybe this one is too trivial.
-------------------
Question 4
Says:
You need to access your company?s secure...
A simple typo entering a ? instead of a '.
----------------
Question 5
In the explanation it uses the word "host?s" instead of "host's".
-------------------
Question 33
in the explanation the word "company?s" should be replaced with the word "company's".
-------------------
Question 38
In the explanation
The last sentence says
In this case, 256 ? 192 is 64, and 64 ? 2 is 62.
another obvious typo that should read:
In this case, 256 - 192 is 64, and 64 - 2 is 62.
-------------------
Question 48
The last word in the explanation has a typo, it says DSO?s not DSO's
-------------------
Question 49
The explanation has a typo stating multiple AP?s instead of multiple AP's.
-------------------

Just because we can, let's look at another example. Based on the output of the next routing table, which interface will a packet with a destination address of 10.10.10.14 be forwarded from?

Surely you meant to. Otherwise it would be like saying who is allowed to write a letter to Santa Clause, based on where they live.

The chapter is about routing, and routing is about where things (packets) go, not where they have been, right? :confused:

no, that is what I meant. We are talking about a routing table and how IP will parse the routing table and forward packets.

[lammle]

Todd,
Perhaps I was unclear. In the BOOK the questions are fine. They make perfect sense. But on the CD it is not possible to chose more than one answer. The test engine has radio buttons allowing only one choice, where as check boxes allow the reader to select more than one answer. I understand that there is only one correct answer (all of the above). I was trying to point out the way the test engine functions with those two questions. In other words, the questions are fine, the HTML is flawed.


No, I know this. I didn't make a mistake, Sybex did on the CD. I was very upset about this and they are making the fixes. How this happened I have no idea, but I am not in control of the CD in any way.

No, the source interface is how a router looks at how to forward a packet to a destination. No Error

I already went through it and reported them all.
It's hard for me to beleive the errors they made.
However, they are suppose to be making a new CD

[frankenpaper]

No, the source interface is how a router looks at how to forward a packet to a destination. No Error
I went back and looked at it again, but I am still a bit lost here. I will go back and re-read the entire section after I finish the book.

I am not positive on this one so I thought I would tell you what I think is correct.

To add a route to the destination 10.1.1.0 with the subnet mask of 255.255.255.255 and the next-hop address 10.2.2.2, type route add 10.1.1..0 mask 255.255.255.0 10.2.2.2.
did you mean to say '... add 10.1.1.0 ...'?

Question 1
Host 1 sent a SYN packet to Host 2. What will host 2 sent in responce?
A. A.ACK
B. NAK
C. CYN-ACK
D. SYN-NAK
E. SYN

Page 58
Answer 1
1. C. To set up a connection-oriented session, this is called a three-way handshake and the transmitting host sends a SYK packet, the receiving host sends a SYK-ACK, and the transmitted host replies with the last SYN packet. The session is now set up.

I would think you meant SYN and SYN-ACK

Hi
I’m now studying for the Comptia Network+, and I find some errors, and I would like to fix them in my book so there will be no errors, one of the big errors I found is on page 285 #3,

192.168.100.66/27. A /27 is 255.255.255.224. The fourth octet is a block size of 32. Count by 32s until you pass the host address of 66. 0, 32, 64. The host is in the 32 subnet, broadcast address fof 63. The valid host range is 33-62.

I believe it should read
192.168.100.66/27. A /27 is 255.255.255.224. The fourth octet is a block size of 32. Count by 32s until you pass the host address of 66. 0, 32, 64, 96. The host is in the 64 subnet, broadcast address fof 95. The valid host range is 65-94.


I was really upset when I sew such a big mistake, so who knows if I’m not studying more mistakes,
so please let me know where i could find this mistakes,
thanks
