Question
128 CHAPTER THREE THREE: Concepts in IP Addressing Indy connected them and Greg have configured their own Windows 8 PCs and with ath crossover cables. They can't seem to share their illegally downloaded MP3 es, however. Given their configurations, what could be the problem? s configuration: 1P:192.168.0.65 Mask:255.255.255.192 s configuration: P:192.168.0.62 Mask: 255 255 255.192 z>. - Indy is using a broadcast ID for his IR Greg is using an invalid mask. Indy's IP is in one of the zero subnets. Greg and Indy are using IPs in different subnets. O 0 2 2. You are given an old router to practice for your CCNA. Your boss, Dave, has spent a lot of time teaching you subnetting. Now he challenges you to apply your knowledge. He hands you a note that says the following Given the subnetted address space of 192.168.1.0/29, give the EO interface the first valid IP in the eighth subnet. Give the So interface the last valid IP in the 12th subnet. The zero subnets are avai Which two of the following are the correct IP and mask configurations? Choose two. 10. t.

Answer for
9-- D
Answer D is correct. With that mask, the Increment is 64. Greg is in the first subnet, and
Indy is in the second. Without a router between them, their PCs will not be able to communicate
above layer 2. Answer A is incorrect; the Broadcast ID for Indy would be .63.
Answer B is incorrect; nothing is wrong with the mask. Answer C is incorrect; the Zero
Subnets are the first and last created, and Indy is in the second subnet. The question
does not mention the Zero Subnets, and in any case Windows XP fully supports them
10-- C and F
The correct answers are C and F. This is an Increment question. The Increment here is 8,
so you should start by jotting down the multiples of 8 (those are all the NetIDs), and
then noting what 1 less than each of the NetIDs is (those are the Broadcast IDs). From
there, it is easy to find what the first and last IPs in each subnet are. (Remember that
Dave says we can use the Zero Subnets.) Answers A and D are incorrect because they
do not use the subnetted address space Dave requested. Answer B is incorrect because
it is a NetID. Answer E is incorrect because it is a Broadcast ID.
