If they ask for fewest lines, and that no additional hosts are blocked, I
would lean towards B.
If they just asked that no additional hosts were blocked, and did not
specify that you should use the least number of lines, then either would be
correct.
If they asked that no additional hosts were blocked, and specified that your
access-list could only use a single permit statement, then A would be
correct.

Okay, so this demands the question....
Which would be the "right" answer for a CCIE lab???
A)
access-list 1 deny 10.10.10.100 0.0.0.3
access-list 1 deny 10.10.10.104 0.0.0.7
access-list 1 deny 10.10.10.112 0.0.0.15
access-list 1 deny 10.10.10.128 0.0.0.15
access-list 1 deny 10.10.10.144 0.0.0.3
access-list 1 deny 10.10.10.148 0.0.0.1
access-list 1 deny 10.10.10.150 0.0.0.0
access-list 1 permit any
or B)
access-list 1 permit 10.10.10.96 0.0.0.3
access-list 1 deny 10.10.10.96 0.0.0.31
access-list 1 permit 10.10.10.151 0.0.0.0
access-list 1 permit 10.10.10.152 0.0.0.7
access-list 1 deny 10.10.10.128 0.0.0.31
access-list 1 permit any
Looks like B has fewer lines, but both are correct.
I'm just curious. I have no desire to take the lab.
