Refer to the exhibit. A network administrator must allow traffic from the 10.10.0.0/24 subnet to the WAN on interface Serial0. What is the effect of this configuration when the administrator applies the command?

  • A The router accepts all incoming traffic to Serial0 with the last octet of the source IP set to 0.
  • B The permit command fails and returns an error code.
  • C The router fails to apply the access list to the interface.
  • D The sourced traffic from IP range 10.0.0.0 - 10.0.0.255 is allowed on Serial0.
Explanation

The command ip access-list 10 in is invalid Cisco syntax. The correct interface subcommand is ip access-group 10 in. Because the syntax is invalid, the router fails to apply the ACL to the interface and returns a configuration error.
