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.

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.

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.

You are a called upon to troubleshoot connectivity problems to a network device on a production floor. You have used ping and traceroute to verify that you cannot connect to the device from the management network. The network is 209.165.202.128/27 and the device has been given the IP address 209.165.202.158 and mask 255.255.255.224. You have verified that you can reach the device with your computer connected to the same switch as the device. What could be the cause of this problem?

A. The device is set to the wrong subnet mask.

B. The device is set to the wrong IP address.

C. The device has no IP default gateway.

D. The device is connected to a switchport in the wrong VLAN.

What are two recommended tools or commands that allow you to troubleshoot connectivity between two devices in different IP networks? (Choose two.)

A. show interface status

B. show spanning-tree

C. ping

D. show interfaces gigabitEthernet x/y switchport
