A data center deign requires monitoring of their business critical voice and video services accessed by remote locations. Which two items are applicable? (Choose two)

NBAR performs deep packet inspection for application classification but is not a flow-export or monitoring tool; it cannot generate the per-flow reporting needed to distinguish applications that share QoS markings for performance monitoring purposes.

Requiring a unique CoS value is a Layer 2 marking constraint that contradicts the scenario premise where shared markings already exist and is not a prerequisite for IPFIX-based flow monitoring.

IPFIX (IP Flow Information Export) records flows using attributes such as source/destination IP address, source/destination port, and protocol, allowing it to distinguish individual application flows even when multiple applications share identical DSCP or CoS markings that would otherwise appear indistinguishable.

A unique QoS profile per application is not a monitoring requirement; IPFIX differentiates flows using network-layer attributes and does not require separate QoS profiles to operate accurately.

Assigning unique DSCP values would aid classification but directly contradicts the scenario condition in which applications already share DSCP or CoS values, making this option inapplicable to the stated problem.

Assigning reporting data to a QoS profile ties the collected flow statistics to the correct service class, ensuring that the monitoring system produces accurate, meaningful performance data for each business-critical application rather than aggregated or misattributed results.
