Managing Industrial Networking for Manufacturing with Cisco Technologies 試験
Question No : 1
Which statement is true regarding ProfiSAFE?
Question No : 2
It is common to use Resilient Ethernet Protocol (REP) on the manufacturing floor as a resiliency protocol, as opposed to the Enterprise where it is not generally deployed. What are two reasons why REP is more suitable for the plant floor? (Choose two)
Question No : 3
51.100.1 but are unable to reach any other IP addresses on the Internet. The ISP confirmed that their configuration is correct. Which option would likely correct the problem?
Question No : 4
Refer to the exhibit.
SW1, SW2 and virtual switch are connected in a loop. SW1 and SW2 are standard layer-2 switches. Which loop prevention mechanism is best suited for use within this topology?
Question No : 5
You are making changes to a Stratix 5700 using an Add On Profile (AOP) and a controller which is on-line with RSLogix5000. When do the changes you have made get published to the switch?
Question No : 6
Which command globally enables QoS on a Cisco Industrial Ethernet switch?
Question No : 7

Question No : 9
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 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)
Question No : 10
Cisco Industrial Ethernet switches are capable of sending alarm messages to ProfiNET management stations using the ProfiNET-IO protocol. Which four are alarms that can be configured for an interface? (Choose four)
Question No : 11
After commissioning several Stratix 5700 switches in a ring topology, you want to verify the installation against the network logical design. Specifically, you want to verify where the
IGMP querier resides. What command can be issued in CLI to display the IP of the querier per VLAN?
Question No : 12
Your supervisor calls you and tells you that one of the Stratix 5700 switches is not assigning all CIP explicit messages to the proper QoS queue. The switch was deployed with the ab-global macro and CIP explicit messages were previously being assigned to the proper QoS queue. You suspect the access-lists associated with the ab-global macro have been changed. Look at the following access list from the switch configuration:
access-list 101 permit udp any eq 2222 any dscp 55
access-list 102 permit udp any eq 2222 any dscp 47
access-list 103 permit udp any eq 2222 any dscp 43
access-list 104 permit udp any eq 2222 any
access-list 105 permit udp any eq 44818 any
access-list 105 permit tcp any eq 44816 any
What needs to be done to fix the above access list?
Question No : 13
