A) 69/0x2102 B) 183/B7
C) 173/A6 D) 83/0xC5
 
Answer & Explanation Answer: B) 183/B7

Explanation:

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.

Q:

The network with ip address 192.168.100.0/27 is to be used on a router. If ip subnet-zero is configured, which statement describe the resulting number of available subnets and hosts?

A) 7 usable subnets, each with 32 host addresses B) 8 usable subnets, each with 30 host addresses
C) 8 usable subnets, each with 27 host addresses D) 7 usable subnets, each with 24 host addresses
 
Answer & Explanation Answer: B) 8 usable subnets, each with 30 host addresses

Explanation:

Because subnet zero is configured and we have a class C address (192.168.100.0) then the network portion will have 3 bits so 8 subnets will be available. The rest of the bits, 5, represent the available hosts, so 2^5=32, but only 30 are available, 0 ad 31 are network and broadcast respectively.
