QUESTION 117
The enterprise network WAN link has been receiving several denial of service attacks from both IPv4 and
IPv6 sources. Which three elements can you use to identify an IPv6 packet via its header, in order to filter
future attacks? (Choose three.)
A. Traffic Class
B. Source address
C. Flow Label
D. Hop Limit
E. Destination Address
F. Fragment Offset
这个题网上有两个版本的答案，到底哪个是对的，个人理解的是这个问题问的是在v4和v6都有的流量里怎么鉴别出v6的流量，更偏向ACD一些
