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.

What is port based memory buffering?

. Port-based memory. In port-based memory buffering, frames are stored in queues that are linked to specific incoming and outgoing ports. Shared memory. Shared memory buffering deposits all frames into a common memory buffer, which all the ports on the switch share.

Which method of memory buffering would work best for this task?

Which method of memory buffering would work best for this task? With shared memory buffering, the number of frames stored in the buffer is restricted only by the of the entire memory buffer and not limited to a single port buffer. This permits larger frames to be transmitted with fewer dropped frames.

What happens to runt frames received by a Cisco Ethernet switch?

What happens to runt frames received by a Cisco Ethernet switch? The frame is dropped.

Which switch mode operation reads only the first 64 bytes before making a switching decision?

The reason fragment-free switching stores only the first 64 bytes of the frame is that most network errors and collisions occur during the first 64 bytes of a frame.

What is the purpose of frame buffer on a switch?

Explanation: The large frame buffers on a switch hold the ingress traffic until such time that the slower egress port can transmit the data. This reduces the number of dropped frames and alleviates network congestion.

What does the term port density represent for an Ethernet switch?

Explanation: The term port density represents the number of ports available in a switch. A one rack unit access switch can have up to 48 ports. Larger switches may support hundreds of ports.

Which statement is true about broadcast and collision domains?

Which statement is true about broadcast and collision domains? The size of the collision domain can be reduced by adding hubs to a network. The more interfaces a router has the larger the resulting broadcast domain. The more interfaces a router has the larger the resulting broadcast domain.

What describes Ethernet CCNA?

What statement describes Ethernet? It defines the most common LAN type in the world. It is the required Layer 1 and 2 standard for Internet communication. It defines a standard model used to describe how networking works.

Which three fields are found in an 802.3 Ethernet frame choose three?

Explanation: The fields of an Ethernet frame are the preamble, destination and source address, length, data, and FCS.

What is the maximum size of an Ethernet frame?

To recap, Ethernet has a minimum frame size of 64 bytes, comprising an 18-byte header and a payload of 46 bytes. It also has a maximum frame size of 1518 bytes, in which case the payload is 1500 bytes.

What is a characteristic of store-and-forward switches?

Store-and-forward switching has two primary characteristics that distinguish it from cut-through: error checking and automatic buffering.

Which characteristic describes cut-through switching?

Cut-through switching reduces latency by forwarding frames as soon as the destination MAC address and the corresponding switch port are read from the MAC address table. This switching method does not perform any error checking and does not use buffers to support different Ethernet speeds.

Which switching method is lowest?

Explanation:Fast-forward switching begins to forward a frame after reading the destination MAC address, resulting in the lowest latency.
