Scenario 9-1
641
Finally, this chapter contains more configurations for almost all options already covered in the
book. If you can configure these options without online help, you should feel confident that you
can choose the correct command from a list of five options in a multiple-choice question.
If you have enough time, review all parts of each scenario. However, if you have limited time,
you can review only part of a scenario. For example, the solutions to Part A of each scenario
are the background information for Part B; the solutions to Part B of each scenario are the
background information for Part C. So, if you read Part A or B, decide you already know those
details, and don't want to take the time to wade through your own answer, just look at the
answer in the book; it will lead you into the next part of the scenario.
If you are reading this chapter as your final review before taking the exam, let me take this
opportunity to wish you success. Hopefully you will be relaxed and confident for your exam--
and hopefully this book has helped you build your knowledge and confidence.
Scenario 9-1
Part A of Scenario 9-1 begins with some planning guidelines that include planning IP addresses,
IPX network numbers, the location of SAP filters, and the location of IP standard access lists.
After you complete Part A, Part B of the scenario asks you to configure the three routers to
implement the planned design and a few other features. Finally, Part C asks you to examine
router command output to discover details about the current operation. Part C also lists some
questions related to the user interface and protocol specifications.
Scenario 9-1, Part A--Planning
Your job is to deploy a new network with three sites, as shown in Figure 9-2.
The decision to use point-to-point serial links, as well as the product choices, has already been
made. For Part A of this scenario, perform the following tasks:
1
Plan the IP addressing and subnets used in this network. Class B network 163.1.0.0 has
been assigned by the NIC. The maximum number of hosts per subnet is 100. Assign IP
addresses to the PCs as well.
2
Plan the IPX network numbers to be used. You can choose the internal network numbers
of the servers as well.
3
Plan the location and logic of IP access lists to filter for the following criteria: Hosts on
the Ethernet attached to R1 are not allowed to send or receive IP traffic to or from hosts
on the Ethernet attached to R3. (Do not code the access lists; just code the location and
logic for the access lists. Part B will ask for configuration, and because the answer to Part
B will be based on where the access lists are placed, you probably will want to see the
answer in Part A before configuring.)
