What are the two main types of access control lists (ACLs)?

1.Standard

2.IEEE

3.Extended

4.Specialized

  • A.1 and 3
  • B.2 and 4
  • C.3 and 4
  • D.1 and 2

Answer: D

Correct answer: 1 and 3

The two main types are standard and extended. A standard access list filters on the source address only and is placed close to the destination; an extended list filters on source and destination address, protocol and port, and is placed close to the source so that unwanted traffic is dropped before it crosses the network. IEEE and Specialized are not access list types at all.
