Which option is not a typical use of ACLs?
- VPN traffic identification
- NAT control
- PPP configuration
- route advertisement filtering
Explanation: Access Control Lists (ACLs) are primarily packet classification tools rather than protocol configuration mechanisms. According to the sources, they are typically used to define interesting traffic for a VPN, filter route advertisements, and control traffic for services like NAT. While an ACL can be applied to a PPP interface to filter data, it is not a "typical use" for configuring the underlying parameters or properties of the PPP protocol itself.
