Answer - C .Temporal A period of time, value in microseconds. When you configure a temporal buffer, you must also configure a transmit rate. The system calculates the queue buffer size by multiplying the available bandwidth of the interface times the configured temporal value and transmit rate. When you specify a temporal method, the drop profile is assigned a static buffer and the system starts dropping packets once the queue buffer size is full. By default, the other buffer types are assigned dynamic buffers that use surplus transmission bandwidth to absorb bursts of traffic.
