Cisco Cisco Industrial Networking Specialist 200-401 Questions & Answers

• Question 51:

  Why is SSH preferred over Telnet as a method of accessing a network device to alter or view the configuration?

  A. Telnet encrypts only the login information, not the entire transmission.

  B. SSH requires fewer network resources and no additional configuration.

  C. Telnet is more difficult to use and configure than SSH.

  D. SSH encrypts the login and session information.

  Correct Answer: D

• Question 52:

  What is the purpose of Spanning Tree Protocol?

  A. to prevent routing loops

  B. to create a default route

  C. to provide multiple gateways for hosts

  D. to maintain a loop-free Layer 2 network topology

  E. to enhance the functions of SNMP

  Correct Answer: D

• Question 53:

  Exhibit: Refer to the exhibit. CCNA.com has the industrial network shown in the exhibit. All switches are configured as layer 2 switches and are using VLAN 1 as their management VLAN. Each VLAN 1 interface has been assigned the correct IP address. What is the purpose of assigning a default gateway to SW-C switch?

  

  A. allows connectivity between the VLAN 1 interface on SW-C and other devices in the network.

  B. allows connectivity between Host A and other devices in the network.

  C. allows connectivity between Host B and other devices in the network.

  D. allows the switch to pass traffic between Host A and Host B

  Correct Answer: A

• Question 54:

  Which three of the following components must be elected before the Spanning Tree Protocol can converge in a switched LAN? (Choose three.)

  A. designated ports

  B. duplex operating mode

  C. fast mode ports

  D. root bridge

  E. root ports

  F. BDPU priority

  Correct Answer: ADE

• Question 55:

  What are two benefits of a star network topology? (Choose two.)

  A. Disruption of the entire network is not required when adding new machines.

  B. Any problem which leaves the network inoperable can be traced to the central hub.

  C. This network type requires less cable as compared to linear bus topology.

  D. The performance of one of the numerous nodes cannot reflect on the performance of other nodes.

  E. The performance of the entire network is directly dependent on the performance of the hub.

  Correct Answer: AB

• Question 56:

  Exhibit:

  

  Which two statements are correct for a safe wiring installation to the terminal block of the switch or endpoint? (Choose two.)

  A. Insert a green ground wire into the terminal block that is marked RT for return.

  B. Verify that DC power is live and within 24 VDC voltage range before starting wiring.

  C. Verify that the DC power circuit includes an overcurrent protective device that limits the DC current to 5

  D.

  E. Because this is a low-voltage DC circuit, anyone can install this wiring without electrical training or qualifications.

  F. Connect the positive 24 VDC conductor to the V terminal and connect the negative 24 VDC return wire to the RT terminal.

  G. A ground wire can optionally be connected to the screw terminal on the front of the switch.

  Correct Answer: CE

• Question 57:

  Which option allows an EtherNet/IP I/O device to be safely installed where it is subject to water immersion?

  A. The device is rated IP20 and the power wiring is installed securely to the terminal block.

  B. The device is rated IP67 and a power cordset is used.

  C. The device is rated IP67 and immersed to 10 m.

  D. The device is rated IP20 and immersed to 10 m.

  Correct Answer: B

• Question 58:

  Exhibit: Refer to the exhibit. What are three traffic and interconnection requirements for the devices in the exhibit? (Choose three.)

  

  A. The EtherNet/IP drive connections are in a high-voltage area and need protection from electromagnetic noise, so shielded cable that is rated for 600 V is advised.

  B. EtherNet/IP devices such as the controller, drive, VoIP phone, and IP camera should be in the same VLAN.

  C. CIP traffic has the highest bandwidth requirement so it needs the highest QoS setting.

  D. EtherNet/IP drive traffic has high sensitivity to random drops, latency, and jitter.

  E. Real-time motion control and VoIP traffic can share the same VLAN with the proper QoS setting.

  F. IEEE1588 and PTP are important for ensuring real-time synchronization.

  Correct Answer: ADF

• Question 59:

  Exhibit:

  

  Refer to the exhibit. Which port should a PLC with IP address 192.168.3.65 be plugged into in order to communicate to the rest of the network?

  A. FastEthernet1/1

  B. FastEthernet1/2

  C. FastEthernet1/3

  D. FastEthernet1/4

  E. FastEthernet1/5

  Correct Answer: C

• Question 60:

  Exhibit:

  A. the address of the switch interface that is connected to router interface Fa0/0

  B. the address of the switch interface that is connected to router interface Fa0/1

  C. the address of the host that is connected to Network A

  D. the address of the host that is connected to Network B

  E. the address of the router interface Fa0/0

  F. the address of the router interface Fa0/1

  Correct Answer: E
