Question 660
At a public utility network in Calgary, a post-change check targets this documented issue: The collector receives NetFlow v9 data records but cannot decode fields because the template has not been received. Which observation is the strongest evidence that the repair worked?
Explanation
Correct Answer
This is the observable outcome for netflow v9 template information. It tests whether the targeted change, 'Ensure the exporter sends the corresponding NetFlow v9 templates and collector receives them', actually resolved the reported issue at a public utility network in Calgary. The original failure was: The collector receives NetFlow v9 data records but cannot decode fields because the template has not been received.
Incorrect Answers
That observation verifies flow monitor interface direction in a different situation, such as when netFlow statistics are empty for inbound traffic because the flow monitor was applied only in the outbound direction. For the reported netflow v9 template information incident at a public utility network in Calgary, the required acceptance evidence is: Decoded flow records display the expected fields after the template is learned. This other result does not test that condition directly.
That observation verifies high-rate sampled flow visibility in a different situation, such as when a high-speed interface exports excessive flow volume and overwhelms the collector, while an engineer proposes dropping all flow monitoring. For the reported netflow v9 template information incident at a public utility network in Calgary, the required acceptance evidence is: Decoded flow records display the expected fields after the template is learned. This other result does not test that condition directly.
That observation verifies flexible netflow exporter target in a different situation, such as when a flow monitor collects records locally but the collector receives nothing because its exporter destination is wrong. For the reported netflow v9 template information incident at a public utility network in Calgary, the required acceptance evidence is: Decoded flow records display the expected fields after the template is learned. This other result does not test that condition directly.
