Q.1 Attempt all parts of this question. (30 marks)
Write down True or False for the following (10 marks)
- Routers operate at all the three layers (physical, data link and network) but forwarding decision is based only on information from network layer.
- UDP is mainly used for secured communication at Transport layer.
- ARP broadcast request is used to map logical address (IP) to physical address (MAC address).
- Switch is a layer 2 device where all ports are in one broadcast domain.
- Subnetting (also called subnetwork) is the logical division of IP address in order to have more networks for better control and management.
- Switch is a layer 1 (Physical Layer) device in the OSI reference model.
Choose the correct option. (10 marks)
