It is common to use Resilient Ethernet Protocol (REP) on the manufacturing floor as a resiliency protocol, as opposed to the Enterprise where it is not generally deployed. What are two reasons why REP is more suitable for the plant floor? (Choose two)
- A. REP is only supported on Industrial Ethernet switches, it is not supported on Catalyst switches.
- B. REP converges faster than Spanning Tree, allowing for greater network availability.
- C. REP supports Industrial Ethernet protocols better because it moves the packets faster.
- D. Running dual cables from access switches to an aggregation switch can have a much higher cost on the plant floor than in the Enterprise and running a ring protocol like REP provides resiliency at a lower cost.
- E. Industrial protocols can be negatively impacted by the number of nodes the Ethernet frame traverses, REP provides a topology with no more than 3 nodes for any data path.
Answer : B,D
Which describes a best practice rule for controlling traffic between the corporate network and the controls network?
- A. Outbound traffic from the control network to the corporate network and outbound traffic from the corporate network to the control network can be restricted based on source and destination address only.
- B. Outbound traffic from the corporate network to the control network should be restricted but outbound traffic from the control network to the corporate network should not be restricted.
- C. Outbound traffic from the control network to the corporate network should be restricted based on source and destination address and service only.
- D. Outbound traffic from the control network to the corporate network should be restricted based on source and destination address, service, and port.
Answer : D

- A.
- B.
- C.
- D.
Answer : C
Which is an issue with running CIP Motion on a REP network and identifies an alternate resiliency protocol that works for CIP Motion?
- A. CIP Motion requires a star topology which is not supported by REP. DLR is a suitable resiliency protocol for CIP motion.
- B. REP convergence is not fast enough. DLR is a suitable resiliency protocol for CIP motion.
- C. CIP Motion requires a star topology which is not supported by REP. RPVST+ is a suitable resiliency protocol for CIP motion.
- D. REP convergence is not fast enough. RPVST+ is a suitable resiliency protocol for CIP motion.
Answer : B

- B. Use of unshielded Patch Cables.
- C. Broken seal on bulkhead connector.

Refer to the exhibit.
A new device, PanelView, has been added to the network. See the table for device details:
All devices are able to ping their default gateway and all other devices except PanelView.
PanelView can only ping its default gateway.
After the administrator has done some investigation they have discovered the following information:
