A network engineer is configuring QoS on a router. The engineer needs to ensure that traffic does not exceed a committed information rate (CIR) of 5 Mbps, but also wants to allow bursts up to 40,000 bytes. The engineer applies a policy with the command: police cir 5000000 bc 40000 be 40000 conform-action transmit exceed-action drop violate-action drop. What is the primary trade-off of using policing instead of shaping in this scenario?

Policing drops excess traffic, which may cause TCP retransmissions, while shaping buffers excess traffic

Policing is not supported on Cisco routers

Policing introduces higher latency than shaping

Policing is more complex to configure than shaping

A network administrator is configuring QoS on a router. The policy map includes a class that matches DSCP AF31 and a police command with cir 2000000 bc 20000 be 20000 conform-action transmit exceed-action set-dscp-transmit af32 violate-action drop. What is the effect on traffic that exceeds the committed burst but is within the excess burst?

Traffic is shaped to the CIR and buffered

Traffic is dropped because the violate-action is drop

Traffic is transmitted unchanged because the conform-action is transmit

Traffic is re-marked to DSCP AF32 and transmitted

A network engineer applies a QoS policy to a router's GigabitEthernet0/1 interface in the inbound direction. The policy includes a class that matches HTTP traffic and sets DSCP AF11. What is the effect on HTTP traffic entering the interface?

HTTP traffic is shaped to a rate on the inbound interface

HTTP traffic is marked with DSCP AF11 as it enters the router, and the marking is used for subsequent queuing decisions

HTTP traffic is dropped because the policy is applied inbound

HTTP traffic is queued in a priority queue on the inbound interface
