Understanding sFlow Monitoring:

sFlow is a packet sampling technology used to monitor traffic in a network. It sends sampled packet data and interface counters to an sFlow collector, which analyzes the traffic patterns.

Information Included in sFlow Datagram:

Option A: The datagram sent to the sFlow collector includes information about the interface through which the packets entered the agent (the switch or router). This is crucial for understanding where in the network the traffic was captured.

Option D: sFlow datagrams also include the source and destination VLAN for the sampled packets. This allows for detailed analysis of the traffic flow within different VLANs.

Conclusion:

Option A: Correct---The ingress interface is included in the sFlow datagram.

Option D: Correct---The source and destination VLANs are also included, providing context for the sampled traffic.

I think the active source field is blank because the EVPN route for this host does not have a valid next hop.
