1. A. Only the source IP address is used to filter the network.
2. E. IP extended lists use source and destination IP addresses, Network
layer protocol files, and port fields in the Transport layer header.
3. C. The mask 0.0.255.255 tells the router to match the first two octets
and that the last two octets can be any value.
4. B, D. The wildcard 0.0.0.0 tells the router to match all four octets.
The wildcard command can be replaced with the host command.
5. A. The first thing to check in a question like this is the access list number.
Right away, you can see that Answer B is wrong because it is using
a standard IP access list number. The second thing to check is the protocol.
If you are filtering by upper-layer protocol, then you must be
using either UDP or TCP. This eliminates Answer D. Answers C and
E have the wrong syntax.
6. C, E. Only the commands show ip interface and show run will tell
you which ports have access lists applied.
7. E. Networks 172.16.16.0 through 172.16.23.0 have a block size of 8.
The wildcard is always one less than the block size; in this example, 7.
8. A. Only Answers A and D are in the right access list number range for
standard IPX access lists. Answer D is wrong, though, because standard
IPX access lists cannot filter on upper-layer applications or
services.
9. F. Networks 172.16.32.0 through 172.16.63.0 have a block size of
32. The wildcard would be 0.0.31.255.
10. B. You don’t add the in or out parameters at the end of the list with
SAP access lists.
