Which of the following is an example of a standard IP access list?

A access - list 110 permit host 1.1.1.1
B access - list 1 deny 172 . 16 . 10 . 1 0 . 0 . 0 . 0
C access - list 1 permit 172 . 16 . 10 . 1 255 . 255 . 0 . 0
D access - list standard 1 . 1 . 1 . 1

Correct Answer: access - list 1 deny 172 . 16 . 10 . 1 0 . 0 . 0 . 0

  B) access - list 1 deny 172 . 16 . 10 . 1 0 . 0 . 0 . 0

Standard IP access lists use the numbers 1 - 99 and 1300 - 1999 and filter based on source IP address only. Option C is incorrect because the mask must be in wildcard format.
