Question

question 16 a layer 2 switch is used to switch incoming frames from a 1000base - t port to a port connected to a 100base - t network. which method of memory buffering would work best for this task? port - based buffering fixed configuration buffering level 1 cache buffering shared memory buffering

Explanation:

Port - based buffering allocates buffers to each port. Fixed - configuration buffering has a set buffer configuration. Level 1 cache buffering is related to cache memory levels. Shared memory buffering allows all ports to access a common pool of memory. When switching frames from a high - speed port (1000BASE - T) to a lower - speed port (100Base - T), shared memory buffering can better manage the flow of data between ports of different speeds as it can dynamically allocate memory resources among ports.

Answer:

D. shared memory buffering
