For Questions 1 to 20, write True if the statement is True, False otherwise.(1 X 20 20 points) In Dijkstra's routing algorithm, a host computes the routes to all other nodes In Distance Vector routing algorithm, a host knows the entire route to its destination. All collisions can be detected in wired LANs All collisions can be detected in wireless LANs 2. 3. 4 5. 6. 7. 8. 9. RTS frames in CSMA/CA can collide. In a wireless network, two transmitters could be hidden from each other In CSMA/CD, time to detect a collision could be arbitranily large. CSMA/CA guarantees that there would be no collisions UDP uses acknowledgements UDP uses cumulative acknowledgements. 255.255.255.1 is a valid subnet mask Port numbers are used by both TCP and UDP The default header size of UDP is 20 bytes. The default header size of TCP is 20 bytes. The default header size of IP is 20 bytes. The default Inter-domain routing protocol for the Internet is BGP 10 13. 14 15. 16._ An IP datagram of length 2000 bytes will be fragmented into 2 fragments when passing through network that has MTU of size 1000 bytes 18 In a Content Distribution Network (CDN), all content from the Origin server is always replicated at the replica servers. 9 In a peer to peer network, the peers act as both clients and servers. 20.Packets collisions can occur in a switch (a layer-2 device). 21. With respect to CSMA/CA, what is Network Allocation Vector (NAV)? (2 points)
