A layer 2 ACL value ranges from 4000-4999. This range is designated for Layer 2 access control lists, which operate on the data link layer of the OSI model, dealing with MAC addresses and such. This classification helps in managing network traffic and permissions based on Layer 2 addresses.

Advanced ACLs (Access Control Lists) typically do not use the 'Source interface' as a parameter. Instead, they commonly include criteria such as the destination port number, protocol number, and time-range to create more precise and detailed traffic filtering rules. The 'Source interface' is not a parameter that is configurable within Advanced ACLs.

The correct answer is that packets from network 10.0.1.0/24 will be denied. The configuration output shows that there are two rules in ACL 2001. The first rule permits traffic from the network 10.0.1.0/24, but the second rule explicitly denies traffic from the same network. In an ACL, the rules are processed in order from top to bottom. Since the second rule denies the traffic, it takes precedence over the first rule allowing it. Therefore, packets from the network 10.0.1.0/24 will ultimately be denied.
