TCP/IP Principles and Protocols Written Assessment
Question 1: You are given a block of IPv4 address with its CIDR notation as 132.34.12.0/23. Your organization needs to have three (3) sub-blocks of addresses to use in its three subnets as shown below:
- First subblock of 120 usable host IP addresses.
- Second subblock of 100 usable host IP addresses.
- Third subblock of 60 usable host IP addresses.
Calculate the subnetworks and answer the following questions for all three of the subblocks. Make sure you show detailed calculations to get full marks in this question.
a) What is the subnet mask of the subblocks?
b) What is first and last address of the subblocks?
Question 2: Download and open 'Assignment one.pkt' using Packet Tracer. It is a working network with a number of network components. Answer the following questions in the context of the given network.
a. List all the network devices (except PCs) present in this network and their associated OSI layers.
b. Identify number of available networking ports and default bandwidth each of the routers support.
c. In the given network there are two types of Ethernet cable used to connect networking peripherals. Identify those two types of networking cables and explain their differences in terms of uses in the given network.
Question 3: Consider 20 pairs of hexadecimal values of an IP datagram below and answer the following questions. Make sure you do necessary conversions to represent the specific value asked for in the questions.
45 00 00 ED FB D1 40 00 FA 06 B6 FC 8A 4D 04 2F 8A 4D B4 72
a) What hexadecimal value/s represents the IP version used in the datagram? What version of IP is used in this datagram?
b) What hexadecimal value/s represents the size of the IP header of the datagram? What is the total length of the IP header in bytes (8 bits) in the given datagram?
c) What hexadecimal value/s represents the total length of this datagram in bytes? What is the total length of the given datagram in bytes (8 bits)?
Question 4: a) Find the topology of the network if Table below is the routing table for R1.
