Both FTP and Telnet use TCP at the Transport layer; however, they both are Application layer protocols, so the Application layer is the best answer for this question.
You must be able to take a binary number and convert it into both decimal and hexadecimal. To convert to decimal, just add up the 1s using their values. The values that are turned on with the binary number of 10110111 are 128+32+16+4+2+1=183. To get the hexadecimal equivalent, you need to break the eight binary digits into nibbles (4 bits), 1011 and 0111. By adding up these values, you get 11 and 7. In hexadecimal, 11 is B, so the answer is 0xB7.
The four layers of the DoD model are Application/process, Host-to-Host, Internet, and Network Access. The Internet layer is equivalent to the Network layer of the OSI model.
DNS uses TCP for zone exchanges between servers and UDP when a client is trying to resolve a hostname to an IP address.
A/30, regardless of the class of address, has a 252 in the fourth octet. This means we have a block size of 4 and our subnets are o,4,8,12,16, etc. Address 14 is obviously in the 12 subnet.
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts - this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.
