Q:

You need to create an access list that will prevent hosts in the network range of 192.168.160.0 to 192.168.191.0 . Which of the following lists will you use?

A) access - list 10 deny 192.168.160.0 255.255.224.0 B) access - list 10 deny 192.168.160.0 0.0.191.255
C) access - list 10 deny 192.168.160.0 0.0.31.255 D) access - list 10 deny 192.168.0.0 0.0.31.255
 
Answer & Explanation Answer: C) access - list 10 deny 192.168.160.0 0.0.31.255

Explanation:

The range of 192.168.160.0 to 192.168.191.0 is a block size of 32. The network address is 192.168.160.0 and the mask would be 255.255.224.0, which for an access list must be a wildcard format of 0.0.31.255 . The 31 is used for a block size of 32. The wildcard is always one less than the block size.
