Question : 8
Which three network mechanisms can be used for securely segmenting an industrial network? (Choose three)
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?
Which two actions are examples of network device hardening for Cisco Industrial Ethernet Switches? (Choose two)
A. Disable unused services
B. Shutdown network ports which are not in use
C. Only allow administrative access using Telnet
D. Deploy IP67 versions of Cisco Industrial Ethernet Switches
E. Set the native VLAN on all trunk ports to VLAN 1
A cookie cutter machine requires 2 standard controllers and a safety controller. All of these controllers and machine level I/O have been placed on VLAN 104. Both standard controllers must monitor a photocell on this machine. Which IP address is used to transfer this status information?
