NetFlow Export Destinations Limit
You are configuring Netflow on various network elements in order to gain visibility into the traffic types used. How many export destinations can this Network data be sent to?

Community Insight
The exam tests knowledge of traditional NetFlow limitations versus Flexible NetFlow scalability; the common trap is assuming modern flexibility applies to the default 'Netflow' terminology used in the question.
This question addresses the maximum number of export destinations supported by standard NetFlow on Cisco IOS devices, establishing that the limit is two.
Many candidates select 'D' (no limitation) because they recall Flexible NetFlow's higher limits or misinterpret general IP SLA capabilities, failing to distinguish between Classic and Flexible NetFlow contexts.

Why the Answer Is Correct
In the context of the CCNP Enterprise certification, 'NetFlow' without specific qualification refers to Traditional (Classic) NetFlow. According to Cisco documentation for IOS, a flow cache can send data to a maximum of two export destinations simultaneously. This limitation exists due to resource constraints and design in the original implementation.Why the Other Options Are Wrong
Options B and C are incorrect because the hard limit for Traditional NetFlow is strictly two, not four or eight. Option D is incorrect because it describes Flexible NetFlow (FNF), which allows up to ten exporters per flow monitor. However, since the question does not specify 'Flexible', the default assumption is the legacy protocol with its stricter two-destination cap.Community Comment Notes
Community consensus strongly supports Option A, citing official Cisco configuration guides. As noted by user HungarianDish_111, "Original NetFlow is limited to only two export destinations per cache." Another commenter, Kdom07, clarified the distinction: "In this exam context assume 'Traditional' unless specifically stated its 'Flexible'." While user tubirubs argued for no limit, this contradicts the standard interpretation of the term 'NetFlow' in older IOS versions tested by this blueprint.Official Reference
Exam Strategy
Always look for keywords like 'Flexible' or 'Advanced' when seeing high numbers for NetFlow features. If the question just says 'NetFlow', assume the baseline Traditional behavior unless the scenario explicitly mentions advanced collectors or flexible monitors.
Frequently Asked Questions
Does Flexible NetFlow have a different limit than Traditional NetFlow?
Yes, Flexible NetFlow supports up to ten exporters per flow monitor, whereas Traditional NetFlow is capped at two.
Why is 'No limitation' incorrect if I can configure multiple collectors?
While you can define multiple collectors, the actual concurrent export capability for a single cache in Traditional NetFlow is restricted to two destinations.
