What are two reasons that explain why using DLR is an appropriate choice for network resiliency?

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)
A. DLR is designed for single network operation at the machine level
B. Moving to a linear topology will reduce the number of cables and so reduce risk of cable failure
C. DLR is the only resiliency technology that is supported by CIP Safety
D. Layer 2 resiliency protocols like REP and RSTP do not have a fast enough convergence time for motion control
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
