Managing Industrial Networking for Manufacturing with Cisco Technologies
Question No: 1
Refer to the exhbit. Which three elements would enable high availability and predictable performance for a motion control application spread across two switches (with video and I/O traffic)? (Choose three)
Configure QoS to give PTP traffic the highest priority
Fiber optic uplinks
Configure QoS to give I/O traffic the highest priority
Interconnect the two switches
Question No: 2
Which five are characteristics that describe Cisco Industrial switches? (Choose five)
Din rail mount
19 inch rack mount
Swappable SD flash card
-5潞C to 45潞C operating environment

Question No: 3
Which in-depth approach is used when deploying defense in an industrial zone?
Besides using a dedicated firewall / DMZ construction use an IOS based firewall on the WAN router connecting the industrial site to the Internet.
Use NTP to make sure that time stamps of log messages are synchronized such that you can do root cause analysis.
Deploy an IDS solution with knowledge about industrial protocols in the industrial zone in combination with a firewall.
Use multiple firewalls from different vendors in such a way that network traffic will have to traverse both firewalls so that security holes of one firewall is caught by the other firewall.

Question No: 5
Refer to the exhibit. Which lines represent a CIP connection being established between two devices?
A. 2914 and 2915
B. 2918 and 2921

Question No: 6
Refer to the exhibit.
All of the vlans listed in the routing table below are trunked using 802.1q and are active on all switches. PLC1, PLC2, and PLC3 each has IP address 192.168.0.1/24 and are connected to ports configured for vlan 50. L2SW1, L2SW2, and L2SW3 are not using vlan trunking for vlan 50.
L3SW1 has following routing table:
10.0.0.0/8 is variably subnetted, 12 subnets, 2 masks C 10.3.138.0/23 is directly connected, Vlan307
C 10.3.136.0/23 is directly connected, Vlan306 C 10.15.153.0/24 is directly connected, Vlan398 C 10.3.142.0/23 is directly connected, Vlan309 C 10.3.140.0/23 is directly connected, Vlan308 C 10.3.186.0/23 is directly connected, Vlan293 C 10.15.154.0/24 is directly connected, Vlan399 C 10.3.184.0/23 is directly connected, Vlan292 C 10.3.190.0/23 is directly connected, Vlan295
C 10.3.188.0/23 is directly connected, Vlan294 C 10.3.182.0/23 is directly connected, Vlan291 C 10.3.180.0/23 is directly connected, Vlan290
PLC1, PLC2, and PLC3 cannot be reconfigured. What can be done to be able to simultaneously communicate with PLC1, PLC2, and PLC3?
Enable NAT on L3SW1
Enable NAT on L2SW1 – L2SW3
Enable NAT on L2SW4
Add vlan 50 to L2SW4 and assign the administrator#39;s an IP address on 192.168.0.0/24 network
Question No: 7
Profinet has been disabled on a Cisco Industrial Ethernet switch, which CLI commands correctly enable ProfiNET on VLAN 10?
switch(config)#profinet switch(config)#profinet vlan 10
switch#enable profinet switch(config)#profinet vlan 10
switch(config)#profinet switch(config)#vlan 10 switch(config-vlan)#profinet
switch#enable profinet switch(config)#vlan 10 switch(config-vlan)#profinet
Question No: 8
A ProfiNET management system operator is unable to see diagnostic information for a Cisco Industrial Ethernet switch that has been added to a SIMATIC management station.
Based on the provided CLI output, which statement is correct?
switch# show profinet status
State : Enabled Vlan : 201
Id : IE2000-Switch Connected : Yes ReductRatio : 128
GSD version : Mis-match
The assigned ProfiNET VLAN is not valid and should be less than 100
LLDP has been disabled on this switch
The GSD file version on the switch does not match the GSD file version on the management station
The Reduction Ration has been set too low
Question No: 9
A shutdown in the cookie cutter machine was traced to a broken network cable. What are two reasons that explain why using DLR is an appropriate choice for network resiliency? (Choose two)
DLR is designed for single network operation at the machine level
Moving to a linear topology will reduce the number of cables and so reduce risk of cable failure
DLR is the only resiliency technology that is supported by CIP Safety
Layer 2 resiliency protocols like REP and RSTP do not have a fast enough convergence time for motion control
Half of the network traffic goes clockwise on the ring and the other half counter- clockwise, reducing by 50% the impact of cable failure
Question No: 10
Which scenario represents the correct configuration to support the SSIDs of this autonomous access point?
