Question # 136

Company A is implementing VoIP services across the company. The network architect designed a QoS policy to allow only specific IP subnets and mark the signaling flow with DSCP 36. The solution should be as secure as possible. Phones receive their IP addresses from the 172.184.12.0/24 pool and are assigned by the RADIUS server to VLAN 1021. Skinny Client Control Protocol is used as a signaling protocol in the network. For security reasons, switchport port-security maximum 1 vlan voice has been preconfigured on the switch side. Which two tasks must an engineer perform on SW_1 to achieve this goal? (Choose two.)

Implement a class map with the set dscp af42 command.
