CCNA1 Skills Assignment
A locally-based independent bookstore chain that specializes in conspiracy theory titles,
Tin Foil Hat Books, Inc., has become concerned that the international Rothschild bankers
will use their Illuminati connections to cut off the bookstore’s existing internet-based
WAN circuits. Bookstore management is determined to maintain continuity of business
operations by switching to private T1 leased data circuits. While any of them could
instantly name which world leaders have been replaced by solid holograms, or are shapeshifting reptilian aliens, network design and IP subnetting are beyond their grasp, and you
have been hired as the network consultant to put it all together before the PTB (powers
that be) find out and close down all their locations.
Top management has already approved your proposed topology diagram (below). Each
company location has up to ten hosts. Utilizing the classful (all equal-sized subnets) class
C address of 199.9.9.0/24, design a suitably subnetted network that meets the client’s
needs. Work in groups of two, three, or four. Project deliverables will include:




A completed chart showing the subnetted networks, range of available host
addresses, and broadcast address for each subnet.
Complete the diagram below, labeling all network subnets in the style
‘199.9.9.x/yy’.
Justify your choice of subnet mask (# of bits borrowed). Would any other number
of borrowed bits have worked?
Don’t forget that each point-to-point WAN circuit requires its own network
subnet.
Choose one of your subnets, and with your group members, configure two classroom
workstations’ Hyper-V Virtual PC –Windows 7 desktop’s CISCO-RACK NICs network
addresses and subnet masks. Test network connectivity using PING.
Due date: Wednesday, March 9th, 2016, before 9 p.m. (last cisco class final exam day).

Determine the Number of Subnets in the Topology Diagram.
Step 1: How many networks are there? ____
Step 2: How many bits should you borrow to create the required number of subnets? ____
Step 3: How many usable host addresses per subnet did this give you? ____
Step 4: What is the new subnet mask in decimal form? _____________________________
Step 5: How many subnets are available for future use? ____
Fill in the following chart with the subnet information.
