Book Errata
Network+ AIO Certification Exam Guide
by Michael Meyers and Brian Schwarz
Errata
p. vii. First word in the Acknowledgments should be Brian, rather than Brain, although Brian is very brainy.
p. xv. Chapter 13 should read Chapter 11
p. xx. Microsoft Certified Professional (CLP) should read Microsoft Certified Profession (MCP). Microsoft Certified Systems Developer (MCSD) should read Microsoft Certified Solution Developer (MCSD).
p. xxiii, fourth paragraph. Important Notice!! CompTIA has raised the score required to pass the Network+ exam from 68% to 82%, effective January 2000.
p. xxxiii, point I.1.6 and the accompanying note. CompTIA has updated their competencies. The fourth bullet point now reads as follows: "the visual appearance of RJ45 and BNC and how they are crimped." (Emphasis added.) The note that pointed out the earlier RJ 24 error should be deleted.
p. 11, Figure 1.8. The MAC addresses for computers B and D are reversed. C and D should have the same MAC addresses because both are responding to computer A.
p. 63, bulleted list. The 5-4-3 rule is 5 Segments, 4 Repeaters, 3 Populated Segments. The text of the fourth paragraph correctly addresses the 5-4-3 rule, but the bulleted list should read as noted.
p. 76, 100BaseFX cabling distances. The distance limit of 400 meters in the book reflects the distance between two half duplex distance extenders, although that distance is actually now 412 meters. Full duplex extenders have a limit of 2000 meters! Linksys has a nice discussion of fiber (including cabling) at the following URL:
p. 77. The sentence starting on the sixth line should read as follows (changes in bold):
The existence of these hybrid devices enables organizations to roll out 100BaseT in batches, providing high-speed access to the machines that need it.
p. 82, Review Question 7. The question should read as follows:
In the diagram below, which of the following cabling systems could be used for the segment indicated by the arrow? The segment indicated is 200 meters long.
(Choose all that apply)
p. 85, Review Answer 3. The correct answer is B., 100m, rather than C. The answer text is correct.
p. 95. The caption for Figure 3.12 should read "Token Ring uses two of the four available pairs of wires."
p. 101. Review Answer 6 should read as follows (changes in bold): "Because both Token Ring and Ethernet networks can use unshielded twisted pair cabling, Philip has not provided enough information . . . ."
p. 111. The text describing Figure 4.6 is incorrect. Here is how it should read (changes in bold): "In Figure 4.6, machine B receives one file from machine A, another from machine D, and sends a third file to machine C. Machine B needs some means to track its connections...."
p. 134. Figure 5.10 mentions DINO instead of BARNEY. Here's the corrected picture:
p. 146, Review Answer 1. The correct answer is C., 15 characters, rather than A. The answer text is correct.
p. 153, first paragraph, fourth sentence should read (change in bold), "All addresses between 1.x.x.x and 126.x.x.x are Class A addresses."
p. 153, Table 6.1. Class A first decimal values range from 1-126, and the addresses range from 1.0.0.0 to 126.0.0.0. Class E first decimal values range from 240-255.
p. 154, first paragraph. The eighth line (describing a class B address) incorrectly lists the Class B subnet mask as 255.255.255.0, which is the subnet for a Class C address. The full sentence should read as follows: "For the Class B address 187.12.54.123, the default subnet mask is 255.255.0.0."
p. 180, last sentence, and p. 181, first two sentences. The description in the text about which client is doing what in Figure 6.27 has the client names messed up. Here is what the three sentences should say (changes are in bold):
In Figure 6.27, ACCOUNT3, a WINS client, contacts the WINS server to determine the IP address that corresponds to the NetBIOS name SALES1.
Once ACCOUNT3 has the address, it no longer has to rely on a broadcast to reach SALES1. Because SALES1 lies on the far side of the router, a broadcast would not work anyway.
p. 215, first paragraph. "(See Chapter 5 for more information about the SMB protocol.)" should read "(See Chapter 4 for more information about the SMB protocol.)"
p. 243. Figure 8.26 actually displays an illustration of a Token Ring NIC with a DB-9 connector. The text refers to a typical MSAU, which are now very hard to find. Here's a Token Ring switch:

p. 323, Review Answer 5. The correct answer is B., Patch panel, rather than D. The answer text is correct.
p. 323, Review Answer 9. The correct answer is C., replacing the hub with a switch, rather than D. The answer text is correct.
p. 335, Note. PRI ISDN uses 23B+D, rather than 24B+D.
p. 346, Review Answer 3. The correct answer is B., Dial-up Networking, rather than C. The answer text is correct.
p. 383, Review Answer 5. The correct answer is C., Incremental, rather than C and D. The answer text should read as follows: "Of these choices, only incremental backups change the archive bit. Normal (full) backup (not one of the choices) also changes the archive bit."
p. 394. The second incidence of 100BaseFX should be deleted.
p. 407. DNS stands for Domain Name System, rather than Dynamic Name System.
p. 415. The definition of a hub should read as follows:
Hub: An electronic device that sits at the center of a star topology network, providing a common point for the connection of network devices. In a 10BaseT Ethernet network, the hub contains the electronic equivalent of a properly terminated bus cable; in a Token Ring network, the hub contains the electronic equivalent of a ring.
p. 418. ISV should read ISV.
