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




 

Suggested Answer: BCE

Because flows are identified by the 3-tuple of the Flow Label and the Source and Destination Addresses, the risk of theft or denial of service introduced by the
Flow Label is related to the risk of theft or denial of service by address spoofing.
