Step 1
Firewall configurations are essential for network security. Three possible configurations are: a. Packet Filtering: This configuration examines each packet of data entering or leaving the network and allows or blocks it based on predefined rules. b. Stateful Show more…

Sub-module A.2: Short reasoning-based Questions 24 marks 25 minutes Respond to any six of the following reasoning-based questions with short answers. 1. What is the significance of physical addresses in the presence of IP addresses? 2. Give one advantage as well as a disadvantage of using a circuit-switched network instead of a packet-switched network. 3. Why would it be logical to have no memory in a circuit-switching intermediate node? (We do have memory in the intermediate nodes of a packet-switching network, i.e., switches and routers) 4. What is the fundamental difference between flow control and congestion control? 5. How can we distinguish a protocol from a service? 6. Consider the following figure: 223.1.2.6 (1A-23-F9-CD-06-9B) 223.1.4.1 (2A-C3-F1-3D-16-A2) 223.1.4.2 (A3-94-B3-FF-F6-2C) 223.1.3.27 (B1-23-F9-CD-06-00) 223.1.2.1 223.1.2.2 (1A-BD-F9-CD-06-00) 223.1.3.1 223.1.3.2 (1A-23-F9-CD-06-0D) Let's say a packet is being sent from A to B. The packet would reach in 3 Data transfers via physical frames. For each frame, specify what would be the source and destination MAC addresses for the DLL and the source and destination for the IP packet in the networking layer. 7. Should the OSI model (fundamental layers) change as we transition from a conventional Internet to an IoT inclusive Internet enfolding several WSNs? Provide two to three dominant reasons.

Use the following scenario to answer the 10 questions below. You have 3 networks (A, B, and C) and 2 routers (Y and Z). Network A has an address space of 10.1.1.0/24 and is connected to router Y using the interface 10.1.1.1. Network B has an address space of 192.168.1.0/24 and is connected to router Y using the interface 192.168.1.254. Network C has an address space of 172.16.1.0/24 and is connected to router Z using the interface 172.16.1.1. The diagram below represents these connections and interfaces. Router Y Network A Interface: 10.1.1.1 Network B interface: 192.168.1.254 Router Z Network B interface: 192.168.1.1 Network C interface: 172.16.1.1 1. Computer 1 on network B with IP address 192.168.1.233 wants to send a packet to Computer 2 with IP address 10.1.1.205. On which network is computer 2? Network C Network A Network B Not present
