You are working on a router that has established privilege levels that...
The only command that shows which access lists have been applied to an interface is show ip interface Ethernet 0. The command show access-lists displays all configured access lists, and show ip access-lists displays all configured IP access lists, but neither command indicates whether the displayed access lists have been applied to an interface.

You are working on a router that has established privilege levels that...
To view and confirm the access lists that have been applied to the Ethernet 0 interface on the router, you can use the command "show ip interface Ethernet 0" (option D).
Here is a detailed explanation of the answer:
1. Basic understanding:
- In networking, access lists are used to filter network traffic based on certain criteria.
- The "show ip interface" command displays detailed information about the specified interface, including any access lists applied to it.
2. Using the correct command:
- The command "show ip interface Ethernet 0" specifically provides information about the Ethernet 0 interface, including the access lists applied to it.
3. Access list information:
- By executing the command, you will be able to see the access lists (if any) that have been applied to the Ethernet 0 interface.
- Access lists are typically used to control traffic entering or leaving an interface, so it is important to verify which access lists are configured on a specific interface.
4. Alternative options:
- The other options provided in the question are not suitable for viewing and confirming access lists on a specific interface.
- Option A ("show access-lists") displays all configured access lists, but it does not specify the interface.
- Option B ("show interface Ethernet 0") provides general information about the Ethernet 0 interface, but it does not specifically show the applied access lists.
- Option C ("show ip access-lists") displays the configured access lists, but it does not show the access lists applied to a specific interface.
In conclusion, to view and confirm the access lists that have been applied to the Ethernet 0 interface on the router, you should use the command "show ip interface Ethernet 0" (option D). This command provides detailed information about the specified interface, including any access lists applied to it.
