Question #16
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. The safety controller must monitor an emergency stop connected to an I/O adapter on an adjacent machine (VLAN 105). Which packet type will be used?
  1. A
    UDP Multicast TTL = 1
  2. B
    UDP Multicast TTL = 2
  3. C
    UDP Unicast
  4. D
    TCP Unicast

Correct Answer:
C

Question #17
A shutdown in the cookie cutter machine was traced to a broken network cable. What are two reasons that explain why using DLR is an appropriate choice for network resiliency? (Choose two)
  1. A
    DLR is designed for single network operation at the machine level
  2. B
    Moving to a linear topology will reduce the number of cables and so reduce risk of cable failure
  3. C
    DLR is the only resiliency technology that is supported by CIP Safety
  4. D
    Layer 2 resiliency protocols like REP and RSTP do not have a fast enough convergence time for motion control
  5. E
    Half of the network traffic goes clockwise on the ring and the other half counter-clockwise, reducing by 50% the impact of cable failure

Correct Answer:
AD

Question #18
What is the reason that ProfiNET frames are discarded by default on Catalyst switches?
  1. A
    ProfiNET uses a nonstandard Ethernet frame format
  2. B
    The frames have an 802.1q tag with VLAN ID equal to 0 (zero)
  3. C
    Catalyst switches do not support ProfiNET traffic
  4. D
    A ProfiNET VLAN must be configured and enabled on a Catalyst switch

Correct Answer:
B

Question #19
Which statement is true regarding ProfiSAFE?
  1. A
    ProfiSAFE traffic must be carried on a network that is physically separated from automation traffic
  2. B
    ProfiSAFE relies on the error detection mechanisms of Ethernet and TCP/IP to determine if there are network errors
  3. C
    ProfiSAFE can be used in safety applications up to Safety Integrity Level 3 (SIL3)
  4. D
    ProfiSAFE is only used by ProfiBUS PA and ProfiBUS DA devices

Correct Answer:
C

Question #20
Which statement is correct regarding ProfiNET communication classes?
  1. A
    ProfiNET-RT traffic is carried in UDP and TCP packets
  2. B
    ProfiNET-NRT is used to carry time critical status information
  3. C
    ProfiNET-IRT requires switches with hardware time scheduling capabilities
  4. D
    ProfiNET-NRT is prioritized as Layer-2 Class-of-Service 1 (CoS 1)

Correct Answer:
C
