Explanation

Before deploying NetFlow, administrators must plan carefully. (A) CPU utilization is critical because NetFlow processing-capturing, caching, and exporting flow records-adds overhead to the router's CPU; high-traffic devices can be significantly impacted. (B) The destination of NetFlow data matters because a NetFlow collector (like a dedicated server or tool) must be reachable and configured to receive and store the exported data. (C) The number of devices exporting NetFlow determines the volume of data sent to the collector; too many exporters can overwhelm the collector or the network links leading to it. Port availability (D), SNMP version (E), and WAN encapsulation (F) are not primary pre-implementation considerations for NetFlow.
