Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 601

How does a WCCP-configured router identify if the Cisco WSA is functional?

Answer options

• A. If an ICMP ping fails three consecutive times between a router and the WSA, traffic is no longer transmitted to the router.
• B. If an ICMP ping fails three consecutive times between a router and the WSA, traffic is no longer transmitted to the WSA.
• C. The WSA-sends a Here-I-Am message every 10 seconds, and the router acknowledges with an I-See-You message.
• D. The router sends a Here-I-Am message every 10 seconds, and the WSA acknowledges with an I-See-You message.

Correct answer: C

Explanation

The correct answer is C because the WSA actively sends a Here-I-Am message to inform the router of its status, and the router responds with an I-See-You message. Options A and B are incorrect as they relate to ICMP ping failures and do not describe the WCCP communication method. Option D is also incorrect because it reverses the roles of the router and WSA in the message exchange.
