Consider the following scenario and answer the questions,
You run the Saudi Style Company, a specialist business that sells caps and blazers. You received an OBJECT IDENTIFIER 8000 under the enterprises node from IANA. There are two branches for you. Each has an inventory system that can be accessed by the IP address; which have the following OBJECT DESCRIPTORS:
- Branch 1 – 500.500.500.18
- Branch 2 – 500.500.500.19
There are two product categories in each branch's inventory:
- caps
- blazers
Each cap is the same size, and the inventory is a scalar value, capQuantity.
There are several sizes of blazers, and the inventory is maintained in a table, blazerTable, whose columnar objects are,
- blazerSize(index)
- blazerQuantity
Construct an MIB module for your business. As a company president, the goal is to find the inventory of any specific product while sitting in your office.
- Draw an MIB subtree.
- Write an MIB module.
Build a network topology as given below using the Packet Tracer. Use the information given in the topology below to configure the router and PCs. You must also do the following: i. Write the commands used to configure the router. ii. Construct intra-LAN communication and confirm the successful communication by sending packets from the hosts belonging to the same LAN. iii. Construct inter-LAN communication and confirm the successful communication by sending packets from a host belonging to LAN1 to a host belonging to LAN2. (Support your results with screenshots)
Q3
Wireshark is one of the most advanced packet-capturing software, which makes the life of system/network administrators easy and proves its usefulness among the groups of security evangelists. Wireshark is also called a protocol analyzer, which helps IT professionals in debugging network-level problems. This tool can be of great use to optimize network performance. Therefore, you are requested to download the Wireshark tool on your PC and complete the following tasks:
- Create a display filter to see only the SNMP packets.
- Create a display filter to show only TCP FIN and ACK packets sent to your machine from your default gateway in the list pane.
- Create a display filter to see only the ICMP destination host's unreachable packets.

Q4
Network monitoring provides the information that network administrators need to determine, in real time, whether a network is running optimally. With tools such as networking monitoring software, administrators can proactively identify deficiencies, optimize efficiency, and more. Therefore, you are requested to use network monitoring tool on your PC and complete the following tasks:
- Execute the commands nslookup and dig on a host IP address and analyze the results.
- Ping an international site 100 times and determine the delay distribution and packet loss. Repeat at different times of day and night. Explain any variations.
- In diagnosing poor network performance – for example, delays – you need to know where the bottleneck is. Use traceroot to an international site on another continent and isolate the delay in the path.
