HP Comware Switch 1 connects to switch 2 on GigabitEthernet 1/0/1. Switch 2 implements an inbound rate
limit of 600 Mbps. The network administrator wants switch 1 to buffer traffic that exceeds the Switch 2 rate limit
of 600 Mbps and send the traffic at 600 Mbps. All traffic has the same 802.1p priority and is forwarded in priority
queue 2.
What should the administrator apply to the Switch 1 interface GigabitEthernet 1/0/1?

A.
A line rate limit of 600 Mbps on queue 2

B.
A QoS policy with a classifier that matches all traffic and a CAR behavior that sets a CIR of 600 Mbps

C.
A weighted random early discard (WRED) table with a limit of 600 for queue 2

D.
A traffic shaping rate limit of 600 Mbps on queue 2

Explanation:
The line rate of a physical interface specifies the maximum rate of incoming packets or outgoing packets.
Note: Configuring the line rate
Perform the following steps:
1. Enter system view by using the following command:
system-view
2. Enter interface view.
interface interface-type interface-number
3. Configure the line rate for the interface. Use the following command:
qos lr outbound cir committed-informationrate [ cbs committed-burst-size [ ebs excessburst- size ] ]
