Your company needs to baseline web traffic on a per-session basis for network application reporting. Which two mechanisms, when combined, fulfill the requirement? (Choose two.)

Flexible NetFlow monitors traffic at a granular per-flow and per-session level, capturing source/destination IPs, ports, and byte counts that are essential for baselining web sessions.

RMON collects aggregate traffic statistics from network segments but does not provide per-session application-level visibility.

Cisco IP SLA proactively measures network performance metrics like latency and jitter between endpoints, not passive per-session traffic baselining.

Class-Based QoS MIB exposes QoS policy statistics via SNMP for queue and drop counters, not per-session application traffic data.

Network-Based Application Recognition (NBAR) performs deep packet inspection to identify and classify application protocols including HTTP/HTTPS, which enables application-level reporting.
