2THEORY AND SIMULATION EXERCISES PART AAnswer to Question 1:A. Broadcast IP address – It is the IP address using which all the hosts are connected inthe network and it helps the network administrator to verify the successful transmission of thedata packets in the network (Shah et al. 2015). The DHCP and the bootstrap protocol are uses thebroadcast address for locating and transmitting the request from different servers. B. Default Gateway – It is utilized as an access point and that is used by the computersconnected in the network to send data packets to the computer connected in another network. We need the default gateway because without a default gateway the device in the networkcannot communicate with the device outside the network and it remains isolated.C. A subnet mask is a number that is used for defining a range of IP address that can beapplied in a network. The subnet mask is used for breaking an address block into smaller subnetand restricting the connection between the two subnets (Walker et al. 2016). The traffic in anetwork can be limited suing the subnet because the network is partitioned.D. As an example of the broadcasting uses on the TCP/IP is ARP on IP. It is used forupdating the routing tables with the IP address and its corresponding Mac address.Answer to Question 2:Defaults gateway 10.10.30.1

4THEORY AND SIMULATION EXERCISES The arp command is used for the displaying and modification of the ARP cache. TheARP cache is used for maintaining a mapping of the IP address and the MAC address forreducing the lookup time in the network. The arp –a command is used for fetching the details ofthe arp cache without the IP address. b. The ARP stands for Address Resolution Protocol.c. We need the ARP for translating the host address (IP address) to the MAC address andstoring the details of the host and the IP address in a tabular form (Coleman et al. 2015). It mapsthe IP address to the physical address of the device.Answer to Question 3:IPv4 Routing Table

5THEORY AND SIMULATION EXERCISES The IPv4 table have the columns network destination, Netmask, gateway, interface andthe metrics. The network destination and the netmask is used for the getting the details of thenetwork ID. 10.10.30.146. The gateway address defines the next hop address i.e. the address thatis used for the reaching the network address. The interface is used for the demonstration of theavailable interface that is used for reaching the local network address 10.10.30.146. Here thegateway address 10.10.30.1 is used for reaching the interface 10.10.30.146. The metric column isused for demonstration of the cost of the route and can be analyzed for identification of the bestroute from different points in the network.
