Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 18

A network is being migrated from IPv4 to IPv6 using a dual-stack approach. Network management is already 100% IPv6 enabled.
In a dual-stack network with two dual-stack NetFlow collectors, how many flow exporters are needed per network device in the flexible NetFlow configuration?

Answer options

• A. 1
• B. 2
• C. 4
• D. 8

Correct answer: B

Explanation

In a dual-stack environment, each device needs a flow exporter for both IPv4 and IPv6 traffic. Since there are two dual-stack NetFlow collectors, each network device will require 2 flow exporters to handle the separate flows for both protocols, making option B the correct answer. The other options do not provide the correct number of exporters required for dual-stack configuration.
