正確答案: B
問題6
Refer to the exhibit.
CIP Implicit messages from I/O#1 are being marked IP DSCP 47 by the endpoint and this marking is trusted by L2SW4. L2SW4 is configured to map DSCP 47 to output queue 1 threshold 1. You have received feedback that some of these messages are not being received. Executing the show mls interface GigabitEthernet statistics command on L2SW4 results in:
L2SW4# show mls interface GigabitEthernet 1/1 statistics
< output omitted>
output queues dropped:
queue: threshold1 threshold2 threshold3
queue 0 0 0 0
queue 1 309232345 450 0
queue 2 300 10 0
queue 3 91 0 0
Repeating this command results in the counters incrementing for queue 1 threshold 1.
What are two options for reducing the packet loss on this interface while preserving the end-to-end DSCP marking? (Choose two)

問題7
Your controller has a high performance EtherNet/IP interface with port speed of >30,000 packets per second and 80% spare capacity. A new PowerFlex 753 drive will be added to the system with an RPI of 2ms and has been connected to a switch; you have been asked to set up the switch port. You open the EDS file and see that the drive will support 16 CIP connections and has transmit and receive capacity of 1,000 control packets per second.
What do you set as the storm control pps threshold limit for the port?
