Access list Questions

Question 1

Explanation

Below is the range of standard and extended access list:

Access list type Range
Standard 1-99, 1300-1999
Extended 100-199, 2000-2699

In most cases we only need to remember 1-99 is dedicated for standard access lists while 100 to 199 is dedicated for extended access lists.

Question 2

Explanation

The syntax of a named ACL is:

ip access-list {standard | extended} {name | number}

Therefore we can configure a standard acl with keyword “standard” and configure an extended acl with keyword “extended”. For example this is how to configure an named extended access-list:

Router(config)#ip access-list extended in_to_out permit tcp host 10.0.0.1 host 187.100.1.6 eq telnet

Question 3

Access list type Range
Standard 1-99, 1300-1999
Extended 100-199, 2000-2699

Question 4

Explanation

We can use a dynamic access list to authenticate a remote user with a specific username and password. The authentication process is done by the router or a central access server such as a TACACS+ or RADIUS server. The configuration of dynamic ACL can be read here: http://www.cisco.com/en/US/tech/tk583/tk822/technologies_tech_note09186a0080094524.shtml
