A metro service provider is planning Resilient Ethernet Protocol for his backbone. Which two aspects must be considered before the network design is finalized? (Choose two.)
A. Two Resilient Ethernet Protocol segments can be connected redundantly at two points. One connection will be blocked, using the Spanning Tree Protocol defined in IEEE 802.1D.
B. UniDirectional Link Detection Protocol can be enabled on Resilient Ethernet Protocol interfaces to detect unidirectional failures.
C. The guaranteed convergence recovery time is less than 50 ms for the local segment.
D. A Resilient Ethernet Protocol segment is limited to a maximum of seven devices.
E. VLAN load balancing for optimal bandwidth usage is supported in any Resilient Ethernet Protocol segment.
