What are three values that must be the same within a sequence of packets for Netflow to consider
them a network flow? (Choose three.)
A.
source IP address
B.
source MAC address
C.
egress interface
D.

Netflow can only be enabled on router Layer 3 interfaces (So IP address).
NetFlow Ingress is collected on traffic going into (i.e. inBound) an interface. This is how NetFlow collects data. For example, an e-mail message that is considered ingress traffic will originate somewhere outside of a enterprise.
Egress is collected on traffic going out (i.e. outBound) of an interface. Generally, it is used in combination with Ingress, but it doesn’t have to be.
