Hi,
yeah, CISCO wording in their test questions can be very confusing,
I think in this case,
what they're actually asking is:
which of A, B, C or D is NOT AFFECTED by the access-list statement ?
If they asked "what would not be affected"
instead of
"what would not apply"
it would be clearer.
B, C & D are affected by the access-list statement because their ip
addresses are within the
ranges listed in the access-list statement. ( 172.16.16.0/20 and
172.16.32.0/20 )
therefore,
the router will apply a MATCH and deal to those packets as appropriate.
for A, 172.16.1.1 is not in the 172.16.16.0/20 or 172.16.32.0/20 networks
therefore,
there is NO MATCH in the access-list statement
so no access-list statement will be applied to 172.16.1.1 packets
