| Question ID 14447 | What is the purpose of flow control?
|
| Option A | To ensure data is retransmitted if an acknowledgement is not received.
|
| Option B | To reassemble segments in the correct order at the destination device.
|
| Option C | To provide a means for the receiver to govern the amount of data sent by the sender.
|
| Option D | To regulate the size of each segment.
|
| Correct Answer | C |
Explanation Explanation: Flow control is the management of data flow between computers or devices or between nodes in a network so that the data can be handled at an efficient pace. Too much data arriving before a device can handle it causes data overflow, meaning the data is either lost or must be retransmitted. For serial data transmission locally or in a network, the Xon/Xoff protocol can be used. For modem connections, either Xon/Xoff or CTS/RTS (Clear to Send/Ready to Send) commands can be used to control data flow. In a network, flow control can also be applied by refusing additional device connections until the flow of traffic has subsided. Reference: http://whatis.techtarget.com/definition/flow-control
| Question ID 14448 | Which address type does a switch use to make selective forwarding decisions?
|
| Option A | Source IP address
|
| Option B | Destination IP address
|
| Option C | Source and destination IP address
|
| Option D | Source MAC address
|
| Option E | Destination MAC address
|
| Correct Answer | E |
Explanation Explanation: Switches analyze the destination MAC to make its forwarding decision since it is a layer 2 device. Routers use the destination IP address to make forwarding decisions.
