Which two types of access lists can be used for sequencing? (Choose two.)

A.
reflexive

B.
standard

C.
dynamic

D.
extended

Explanation:
Users can apply sequence numbers to permit or deny statements and also reorder, add, or
remove such statements from a named IP access list. This feature makes revising IP access lists
much easier. Prior to this feature, users could add access list entries to the end of an access list
only; therefore needing to add statements anywhere except the end required reconfiguring the
access list entirely.
Restrictions for IP Access List Entry Sequence Numbering
•This feature does not support dynamic, reflexive, or firewall access lists.
•This feature does not support old-style numbered access lists, which existed before named
access lists. Keep in mind that you can name an access list with a number, so numbers are
allowed when they are entered in the standard or extended named access list (NACL)
configuration mode.
