Which statement about Ethernet switches is true? A. Symmetric switching allows connection between pods of unlike bandwidth and does not require memory buffering B. Memory Buffering is used to prevent a bottleneck when pods of different bandwidth are connected on a symmetric switch C. The latency can be reduced if the switch utilizes the store and forward method of switching store and forward is better for error detection D. The cut through method of switching is faster because the switch forwards the packet to the destination as soon as it reads the destination address
