A and F
Dynamic ACLs have the following security benefits over standard and static extended ACLs:
+ Use of a challenge mechanism to authenticate individual users
+ Simplified management in large internetworks
+ In many cases, reduction of the amount of router processing that is required for ACLs
+ Reduction of the opportunity for network break-ins by network hackers
+ Creation of dynamic user access through a firewall, without compromising other configured security restrictions
