| Exam 350-401 | Question id=5724 | Network Assurance |
An engineer must block all traffic from a router to its directly connected subnet 209.165.200.0/24. The engineer applies access control list EGRESS in the outbound direction on the GigabitEthernet0/0 interface of the router. However, the router can still ping hosts on the 209.165.200.0/24 subnet.

Which explanation of this behavior is true?
| A. |
Access control lists that are applied outbound to a router interface do not affect traffic that is sourced from the router. | |
| B. |
After an access control list is applied to an interface, that interface must be shut and no shut for the access control list to take effect. | |
| C. |
Only standard access control lists can block traffic from a source IP address. | |
| D. |
The access control list must contain an explicit deny to block traffic from the router. |
