Answer: A,D

Explanation:

Cisco standard NetFlow version 5 defines a flow as a unidirectional sequence of packets that all share seven values which define a unique key for the flow:

+ Ingress interface (SNMP ifIndex)

+ Source IP address+ Destination IP address

+ IP protocol

+ Source port for UDP or TCP, 0 for other protocols

+ Destination port for UDP or TCP, type and code for ICMP, or 0 for other protocols

+ IP Type of Service

Note: A flow is a unidirectional series of packets between a given source and destination.
