1.What’s a routing table? Keeps track of the routes to use for forwarding datat to its destination
2. What is the most common static route used in a host computer? Default gateway
3. What command is used to view a PC computer 's routing table? Netstat –r /route prints
4. What is meant by a O.O.O.O network address entry with a subnet mask of 0.0. 0.0. in a PC 's routing table? Default route
5. What is the 127.0.0.1 IP address and what is it used for?loopback, the data is routed directly back to the source
14. What is the difference between a static and a dynamic routing protocol?Static routing protocol is of limited use for campuswide network routing but is essential when configuring the default route on

An internal routing protocol
c. Used for routing between the same networks
d. Outdated 50. Define the following:
a. Outbound data traffic-data traffic leaving the network
b. Inbound data traffic-data traffic entering the network
Chapter 9
Section 9-2
1. What networking equipment is usually found in the core of a campus network? Switches
3. What is the advantage of using a layer 3 switch in the core of the campus network?uses electronic hardware instead of software to make routing decisions
5. What is the function of the distribution layer in a campus network?Point where the individual LANS connect together.
7. What is the purpose of the access layer? To connect together networking devices in a LAN
9. Why are routers typically not interconnected at the distribution layer?there are network stability issues when routing large amounts of network data traffic if the networks are full or even partially meshed together
11. List three criteria for selecting the network media. Which is the final decision factor? Desired data speed, distance for connection, budget
13. Define load balancing in terms of data traffic flow in a computer network.
Is used as tool to control the direction of the data flow when multiple routes are available.
15. Define per-packet load balancing. Load balance is guaranteed for all interfaces, but there is no guarantee that the packets will arrive at the destination in the proper order.
In the Network Design Paper I will explain how the University has recently leased a building in Adelphi, Maryland. The measurements of the University is 240 feet long, 95 feet wide and 30 feet tall and broken down to two different floors. This University will be used for education purposes of course, the facility will be made of six instructional labs, seven offices, library, five classrooms, a student lobby and a computer lab. There will be a server room on each floor. The purpose of this paper is to explain the design of the networks in this building. The student accessed computers will be set up on a separate network than the network that they staff will be using.
7. What is the piece of hardware that allows a device to physically access a network?
• “IP (the Internet Protocol) is the most common Network Layer protocol where routing occurs” (Network Design, 2012). I will put in place two wireless network interfaces, which will interconnect with the newly installed fiber optic routing system. Internet nodes will communicate via the IP address, 172.15.100.10.
During this section of my blog you would be able to view all the different types of typical services provided by networks and the purpose of each where I discuss the advantages and disadvantages of them all.
In this section, important functions used to send and get requests to and from the traffic
6. A starting address of 192.0.0.0 and ending address of 223.255.255.255 is a member of which network class? Class C
The purpose of the access layer is to grant user access to network resources; in my case mostly through wireless access points. The access layer’s main characteristics are: high availability, layer 2 switching, QoS, Power over Ethernet.
23. The process used by a router to accept a packet on one interface and forward it out another interface.
Host A will use application for the OS while allowing the PC to still communicate to other devices. Transport will control the data sent and received. The network will place IP addresses to the packets allowing data to be added to the MAC addresses and physical link between host and lines.
Ans: Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers configured for a given network.
As for the functions, bridging devices inspects incoming network data whether to forward to the end user or to discard it.
Primary function of IP protocol = identify individual hosts and groups of hosts using the address
The core layer is considered the backbone of the network and includes the high-end switches and high-speed cables such as fiber cables. This layer of the network does not route traffic at the LAN. In addition, no packet manipulation is done by devices in this layer. Rather, this layer is concerned with speed and ensures reliable delivery of packets.
In line with standard procedures, Static IP addresses will be retained for servers and networked equipment as this allows for an easier collation and management of such devices at each site.
