What is a characteristic of port-based memory buffering?
- All frames are stored in a common memory buffer.
- Frames are buffered in queues linked to specific ports.
- All ports on a switch share a single memory buffer.
- Frames in the memory buffer are dynamically linked to destination ports.
Explanation:Buffering is a technique used by Ethernet switches to store frames until they can be transmitted. With port-based buffering, frames are stored in queues that are linked to specific incoming and outgoing ports.
