Exam 400-101 Question id=754 Infrastructure Services

Which of the following NetFlow features is not unique to version 9 and later?

A. template-based export protocol
B. support for IPv6 flows
C. support for MPLS flows
D. support for multicast flows
E. support for router-based aggregation

Support for routerbased aggregation is not unique to NetFlow version 9 and later. Routerbased aggregation is available with NetFlow version 8 and version 9. NetFlow is a reporting tool that can be used to measure network bandwidth, Quality of Service (QoS), and performance, among other things.

NetFlow version 9 and later use a templatebased export protocol. The purpose of the templatebased format is to enable future versions of NetFlow to extend services without significantly altering the basic NetFlow export format.

NetFlow version 9 and later contain support for IPv6 flows, Multiprotocol Label Switching (MPLS) flows, and multicast flows. Therefore, it is possible with version 9 and later to measure and report on network characteristics beyond basic IPv4 functionality. All versions of NetFlow support IPv4 flows.
