questions

1. In a modern day network  most of the Fast Ethernet and all of the Gigabit Ethernet connections are switched and configured as Full Duplex. On a PC or Server connection, would you expect  see any collisions? Why or why not?

2. A very common question that arises when dealing with Cisco IOS for the first time is "Why does the CLI have to be used? Why not just use a GUI?" What are your thoughts? Why is the CLI even discussed and why insist on using it during a students' first exposure to Cisco routers and switches?

3, The following network 192.168.0.0 255.255.254.0 is a supernet which combines two (2) class C networks.

After reviewing the statement above what can you say about the following ip address 192.168.0.255 /23. (The /23 is CIDR notation) and what are the two class C networks covered by the subnet mask of 255.255.254.0?

4. Part 5B-1 Is the following address a subnet or a supernet? Please explain your comment.

10.168.20.78 255.255.252.0

subnet = more network bits in the mask than the classfull address.

supernet = less network bits in the mask than the classfull address.

Part 5B-2  Is the following address a subnet or a supernet? Explain your answer.

172.0.56.135      255.255.128.0

5. What is the difference between the Startup configuration and the Running Configuration of a Cisco router?

6. In Lab 4 we configured static routes to enable communications from one LAN to another but  we used only one route. Clearly there are two directions to reach the other LANs across the network topology. How would you configure the router using static routes so that both directions could be used with one direction being primary and one being secondary using static routes?

7. What are the pros and cons of using RIPv2 verses Static routes to create end-to-end connectivity?

8. If you had a  medium size network with 20 routers in a STAR Topology such as the one depicted in Module 10 file entitled Network Topology Used in Discussion Question 10 Would you be limited in the routing protocol you choose for the network considering the ones below? Why or Why not?

Static Routes

RIP can not be ruled out . see drawing now open in Module. Something to Consider.

OSPF

EIGRP

9. You have two routes in a routing table going to the same destination network. One is coming from EIGRP and the other was coming from a static route entry.

The EIGRP route is 2 routers away each connected with 1 gigabit ethernet connection. The static entry  takes a path having 5 routers all connected at T1 speeds.

Which route would the routing engine use and why?

The router will  ALWAYS  choose the Route with the lowest Administrative Distance and if the AD of the Static Route has not been changed it will be choosen because it has a AD of ONE (1).

10. A company wants to implement a security policy where one half of their address space is allowed out to the Internet and the other half of their address space is denied access to the Internet.

They are using the Class C address space of 192.168.1.0

What would the ACL look like if you wanted to deny one half of a the Class C network 192.168.1.0 /24 but permit the other half?

Please include the full access-list.

There is more than one correct solution.
