Validate Quality of Service Mappings
Question
A designer is working with a large bank to redesign their network.
The designer wants to minimize complaints regarding slow application response times across the WAN.
It is suspected that currently traffic is not being classified and marked correctly somewhere in the network.
Which tool should the designer recommend to validate quality of service mappings and use?

The tool that the designer should recommend to validate quality of service (QoS) mappings and use in this scenario is IP SLA (Internet Protocol Service Level Agreement).
IP SLA is a Cisco feature that measures network performance in near real-time. It generates simulated network traffic and measures response times and other performance metrics. IP SLA can be used to validate QoS mappings and ensure that traffic is being classified and marked correctly throughout the network.
IP SLA can help the designer to identify where in the network traffic is not being classified and marked correctly. Once the issue is identified, the designer can take appropriate steps to correct the problem, such as configuring QoS policies or updating network equipment.
SNMP (Simple Network Management Protocol) is a protocol used to manage and monitor network devices. SNMP can be used to collect information about network performance, but it is not specifically designed for measuring response times or validating QoS mappings.
IPFIX (IP Flow Information Export) is a standard for exporting flow information from routers, switches, and other network devices. IPFIX can be used to collect information about network traffic, but it is not specifically designed for measuring response times or validating QoS mappings.
Protocol analyzers are tools used to capture and analyze network traffic. Protocol analyzers can be used to identify network issues, but they are not specifically designed for measuring response times or validating QoS mappings.
NBAR (Network-Based Application Recognition) is a Cisco feature that identifies and classifies network traffic based on the application layer protocol. NBAR can be used to classify traffic and apply QoS policies, but it is not specifically designed for measuring response times or validating QoS mappings.
