What are the major steps necessary for implementing routing on a Linux network?
Answer:
NOTE: It is suspected that this question has been reproduced from an exam, quiz or test of some sort.
Step 1
The question is vague, but if you intend to use a Linux machine as a router you'll need multiple physical interfaces connected with your cat 5 or other cabling as well as all switches etc. set up and operating.
Step 2
Configure your connected ethernet interfaces (typically with ifconfig).
Step 3
Configure your routing table (typically with the route command or it's equivalent).
Step 4
Make any necessary changes to your routing host firewall (typically iptables or other).
Step 5
Enjoy the fruit of your labors.
NOTE: Much has intentionally be omitted from this answer because the question is too vague to justify a detailed response.

The Dynamic Host Configuration Protocol (DHCP) lease process consists of four processes. The processes are
1. Discover
2. Offer
3. Request
4. Acknowledgment
In the Discover process the DHCP client initiates the process by trying to discover any DHCP servers in the network. This discover packet is a broadcast packet.

1. From a router or layer 3 switch...ping the ip address.
2. Do show arp | include "type ip address here"
This will give you the mac address associated with the arp.
3. Do a show mac address-table | include "type mac address learned from 2."
This will show you what vlan it is on and what trunk it used ie. gig 2/3 or gig 0/2.
4. Next you do a show cdp neighbor detail to learn ip address of next switch.
5. Repeat step 1.
6. Repeat step 2.
7. Repeat step 3. If mac address is on a trunk port....you have to do step 4 and go to next switch. If mac addess is on switchport....you have found port workstation is plugged into.

Write short notes on how switches learn MAC addresses and they use MAc addresses to forward?
When you connect your computer to a switch, it will automatically detect your computer's settings and will also gather system information, part of this information collected is your MAC address. Every network interface card (NIC) has it's own unique MAC address, and most computers these days have NIC's already installed.

Why the Ptolemaic theory seems logical?
The Ptolemaic theory seemed logical to early astronomers (and philosophers) because their observations appeared to confirm that the stars and Sun rotated around the Earth. Without an understanding of the breadth and scope of the universe, the only logical explanation for the appearance of the Sun in the east and its disappearance in the west every day was that it was circling the Earth.
Will layer 3 switches replace routers completely?
Not likely. For a start, they are much more expensive. They may also require special configuration.
There are many layer 2 switches unmanaged, working with default settings for basic networks. Not everyone needs Layer 3 operations, therefore it doesn't make sense to buy expensive switches with many possibilities for basic operation. If a simple network even needs layer 3 switching, a router can be used in many cases for this purpose. Unfortunately routers are less powerful than switches, therefore it is not recommended solution. Proper answer is very complex, therefore it really depends on the situation.
