Answers
D.

R6(config)# ip access-list extended DDOS

R6(confg ext-nac)# 5 permit icmp host 10.10.10.1 host 10.66.66.66

Suggested answer: D

Explanation:

In this IP SLA tracking, we donít need a IP SLA Responder so the command ìip sla responderî on R6 is not necessary.We also notice that the ACL is blocking ICMP packets on both interfaces E0/0 & E0/1 of R6 so we need to allow ICMP from source 10.10.10.1 to destination 10.66.66.66.
