Answers

1.	B is correct. The 172.1.32.4 address is a Class B address and a private address. The default subnet mask for a Class B address is 255.255.0.0. Answer A is incorrect because the 255.0.0.0 mask is used for a Class A network that has the first octet beginning with 1 to 126. Answer C is incorrect because the 255.255.255.0 mask is used for a Class C network that has the first octet beginning with 192 to 223. Answer D is incorrect because the 255.255.255.255 mask is used to specify that the address is the only one included and is not part of a range.
2.	E is correct. The default gateway should point to a router so that it knows where to forward packets that need to be sent to remote subnets. Therefore, the other answers are incorrect.
3.	E is correct. The 2001::efd3:934a:42a2 address is an IPv6 address. This address is short for 2001:0000:0000:0000:0000:efd3:934a:42a2. Therefore, the other answers are incorrect.
