The question asks to identify an application layer protocol and an internet layer protocol from the given options. DNS is an application layer protocol. TCP is a transport layer protocol, not an internet layer protocol (which is IP). If D is the correct answer, it implies an error in the question's classification of TCP.
.................. is an application layer protocol while ................. is internet layer protocol in TCP/IP reference model. (1) RTP, ICMP (2) DSL, IP (3) SONET, DSL (4) DNS, TCP

- An organization has a Class B network and wishes to form subnets for 64 departments. The subnet mask would be - Ans: B Understanding IP addressing, network classes, subnetting, and how to calculate subnet masks based on the number of required subnets is crucial. - Class B departments require 64 unique subnet IDs. - Bits required for subnets $2^n \ge \text{number of subnets}$. $2^6 = 64$. So, 6 bits are needed for subnetting. - Borrowing bits These 6 bits are borrowed from the host portion of the default Class B address. In a Class B address, the first 16 bits are network, and the last 16 bits are host. The host portion is `00000000.00000000`. - Subnetting the third octet The 6 bits are taken from the first available bits of the host portion, which are in the third octet. - New subnet mask The first 8 bits of the third octet are now part of the network/subnet ID. The first 6 bits of the third octet become '1's, and the remaining 2 bits are for the host. - Calculation `11111111` (first octet) `11111111` (second octet) `11111100` (third octet) `00000000` (fourth octet). - Decimal conversion `11111100` binary = 252 decimal. 103.
