accidentally visiting the URL and becoming infected with malware.

A.
Enable URL filtering on the perimeter firewall and add the URLs you want to allow to the router’s local URL
list

B.
Enable URL filtering on the perimeter router and add the URLs you want to allow to the firewall’s local URL
list

C.
Create a blacklist that contains the URL you want to block and activate the blacklist on the perimeter router

Confidence level: 100%
Remember: A and B are not correct answers because you cannot use a router’s URL list to filter URLs on a
firewall, and vice versa. E is not correct because whitelists are used to allow websites, not block, and that is not
what the question is asking for.

URL Filtering
URL filtering allows you to control access to Internet websites by permitting or denying access to specific
websites based on information contained in an URL list. You can maintain a local URL list on the router.
If the Cisco IOS image on the router supports URL filtering but does not support Zone-based Policy Firewall
(ZPF), you can maintain one local URL list on the router to add or edit an URLs. Enter a full domain name or a
partial domain name and choose whether to Permit or Deny requests for this URL.
