A small manufacturing company has a Class C network address on the plant floor and needs to create five subnets, each accommodating 25 endpoints. Which subnet mask needs to be configured?
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 A.
D. Because this is a low-voltage DC circuit, anyone can install this wiring without electrical
training or qualifications.
E. Connect the positive 24 VDC conductor to the V terminal and connect the negative 24 VDC return wire to the RT terminal.
F. A ground wire can optionally be connected to the screw terminal on the front of the switch.
Which of the following correctly pairs the dotted decimal subnet mask with the correct number of binary bits that represent the subnet mask?
A. 255.255.255.192 and /25
B. 255.255.255.248 and /28
C. 255.255.255.224 and /26
D. 255.255.255.248 and /27
E. 255.255.255.240 and /28
F. 255.255.255.240 and /16
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?
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.
