200-401 - Managing Industrial Networks with Cisco Networking Technologies
Go back to Cisco
What are the two most relevant factors in determining the class of administration that is required to maintain the telecommunications infrastructure? (Choose two.)
the size of the infrastructure
the complexity of the infrastructure
What are two benefits of a star network topology? (Choose two.)
Disruption of the entire network is not required when adding new machines.
Any problem which leaves the network inoperable can be traced to the central hub.
What are two symptoms of duplex mismatch? (Choose two.)
Communication is slow and locks up.
The half-duplex side sees frame sequence errors or runt frames.
What is a characteristic of cables that are used in articulating equipment arms?
high flex rated cable
What is the purpose of Spanning Tree Protocol?
to maintain a loop-free Layer 2 network topology
A router is not operating as expected and the network administrator wants to verify that the router booted using the correct IOS image. Which command should be used to determine which IOS is running on the router?
With what are APC connectors used?
single-mode fiber-optic cables to reduce return loss
With a Cisco IE 2000 switch, what does a port status LED indicate when it is solid amber?
The port is not forwarding.
Which option allows an EtherNet/IP I/O device to be safely installed where it is subject to water immersion?
The device is rated IP67 and a power cordset is used.
How does the optical time domain reflectometer use "backscattered" light to make measurements?
It correlates the returned light pulses with a location in the fiber.
According to the Purdue Reference Model, at which layer would you perform manufacturing operations and control?
What does the Cisco PSIRT issue for significant security issues that directly involve Cisco products and require an upgrade, fix, or other customer action?
Cisco Security Advisories
What two things does a router do when it forwards a packet? (Choose two.)
switches the packet to the appropriate outgoing interfaces
determines the next hop on the path
Which parameter would you tune to affect the selection of a static route as a backup, when a dynamic protocol is also being used?
An administrator has connected devices to an industrial switch and, for security reasons, wants the dynamically learned MAC addresses from the address table added to the running configuration. What must be done to accomplish this?
Enable port security and use the keyword sticky.
At which Layer would you use trace route to validate the path?
With a Cisco IE 2000 switch, what does a port status LED indicate when it is alternating green and amber?
There is a link fault.
At which Layer would you check for spanning tree loops?
With a Cisco IE 2000 switch, what does a power status LED indicate when it is solid green?
Power is present on the associated circuit and the system is operating normally.
What is the most critical step to perform when you are using optical fiber connectors?
Cover with dust caps when not in use.
EtherNet/IP is an Ethernet implementation of which protocol?
The network administrator is using a Windows PC application that is called putty.exe for remote communication to a switch for network troubleshooting. Which two protocols could be used during this communication? (Choose two).
At which Layer would you troubleshoot a cabling issue?
With a Cisco IE 2000 switch, what does a port status LED indicate when it is solid green?
A link is present.
Which option best describes a mechanical, ingress, climatic, chemical and electromagnetic environment that is classified as M3 I3 C3 E3?
Which prompt is used to configure parameters for the Ethernet ports of an industrial switch?
Which two commands can help you to determine what image is running on your industrial switch? (Choose two.)
What is a reason to use user EXEC mode on an industrial switch?
to change terminal settings
What is a reason to use privileged EXEC mode on an industrial switch?
to verify commands that you have entered
At which Layer would you check ACLs for TCP ports being blocked?
Which two pieces of information are commonly tracked as part of a change management process? (Choose two.)
reason for the change
names of people involved in the change
Which characteristic causes multimode fiber-optic cable to differ from single mode?
shorter maximum network segment length for a given bandwidth
What should be done with unused conductors in copper unshielded or shielded twisted-pair network cables?
terminate in their characteristic impedance
You are troubleshooting a connectivity problem and want to isolate the problem. You suspect that a router on the route to an unreachable network is at fault. Which command would you issue to see where the packets stop?
What is the purpose of a time domain reflectometer?
It uses pulses to locate and test for sheath faults, damaged conductors, loose connectors, splices, bridge taps, split pairs, and other problems.
