An administrator must collect basic statistics about the approximate amount of IPv4 and IPv6 flows entering Gi0/0 using NetFlow. However, the administrator is concerned that NetFlow processing during periods of high utilization on Gi0/0 will overwhelm the router CPU. Which configuration minimizes CPU impact and keeps the data flows across Gi0/0 intact?
Option C
sampler R-1-1024
mode random 1 out-of 1024
!
interface Gi0/0
ip flow monitor v4Talkers sampler R-1-1024 input
ipv6 flow monitor v6Talkers sampler R-1-1024 input
Flow samplers are used to reduce the load on the device that is running Flexible NetFlow by limiting the number of packets that are selected for analysis.
Which version of NetFlow does Cisco Threat Defense utilize to obtain visibility into the network?
A. NBAR2
B. IPFIX
C. 8
D. flexible
