29. Recall that some IP addresses are reserved for private use (e.g., in a home, small business, or portions of a larger network). An example are addresses 10.0.0.0 to 10.255.255.255, used for private networks. All IP packets have a source IP address and a destination IP address. Then a Network Address Translation (NAT) is used so that a) Packets passing from private network to public network have their destination addresses modified. b) Typically packets passing from the private network to the public network have their source addresses modified while packets passing from the public network back to the private network have their destination addresses modified. x c) Packets passing from public network to private network have their source addresses modified. d) Typically packets exchanged between private and public networks have both their source and destination addresses unchanged. e) All of the above

30. A major characteristic of private IP addresses is that they a. are not routable on the internet b. are classes addresses c. have the length of 64 bits d. do not require MAC physical addresses

34. In TCP/IP model, the _layer is responsible for segmenting the data. a) Application b) Transport (TCP) X c) Internet (IP) d) Physical e) All of the above

33. In TCP/IP model, which of the following protocols belong to the application layer? a) File Transfer Protocol (FTP) b) Secure Shell Host (SSH) c) Simple Mail Transfer Protocol (SMTP) d) Hypertext Transfer Protocol (HTTP) e) All of the above x

B, C or D which one is correct ???
