Okay, so, on page 459 of Odom's ICND2 book there is the following question:
5. A Frame Relay planning diagram shows the number 101 beside R1, 102 by R2, 103 by R3 and 104 by R4. No other DLCIs are listed. The lead network engineer tells you that the planning diagram uses global DLCI addressing and that a full mesh of VC's exists. Which of the following are true?
A. Frames sent by R1 to R2, as they cross R2's access link, have DLCI 102.
B. Frames sent by R1 to R2, as they cross R2's access link, have DLCI 101.
C. Frames sent by R3 to R2, as they cross R3's access link, have DLCI 102.
D. Frames sent by R3 to R1, as they cross R3's access link, have DLCI 101.
From the back of the book, the correct answers are: B and C. However, I think that D is also correct - am I right?
I checked the errata and saw this for a previous version of the book:
"Page 459 – Chapter 13, DIKTA Question 5, Answer D – the end of the answer should be changed from “… DLCI 102” to “… DLCI 101”.
Cheers,
