Question 3 of 3
Which statement is true when configuring access control lists (ACLs) on a Cisco router?
Only one ACL per protocol, per direction, and per interface is allowed.
Apply the ACL to the interface prior to configuring access control entries to ensure that controls are applied immediately upon configuration.
ACLs filter all traffic through and sourced from the router.
An "implicit deny" is applied to the start of the ACL entry by default.
