Implementing Cisco Network Security (IINS, legacy) — Question 90

A specific URL has been identified as containing malware. What action can you take to block users from accidentally visiting the URL and becoming infected with malware?

Answer options

• A. Enable URL filtering on the perimeter firewall and add the URLs you want to allow to the routers local URL list
• B. Enable URL filtering on the perimeter router and add the URLs you want to allow to the firewalls local URL list
• C. Create a blacklist that contains the URL you want to block and activate the blacklist on the perimeter router
• D. Enable URL filtering on the perimeter router and add the URLs you want to block to the routers local URL list

Correct answer:

Explanation

The correct answer is C, as creating a blacklist specifically targets the URL to block access and activating it on the perimeter router effectively prevents users from visiting the harmful site. Options A and B discuss allowing URLs rather than blocking them, which does not address the issue of malware exposure. Option D, while it mentions blocking, does not specify the creation of a blacklist, which is necessary for effective URL blocking.
