Exam N10-008 topic 1 question 406 discussion

The answer is toast, that's the best thing to put butter on

The bandwidth management technique that uses buffers at the client side to prevent TCP retransmissions when the ISP starts to drop packets exceeding the agreed traffic rate is: A. Traffic shaping Traffic shaping is a bandwidth management technique that involves controlling the rate of traffic sent or received on a network. It uses buffers to smooth the traffic flow and prevent packet loss. In the context described, when the ISP starts to drop packets exceeding the agreed-upon traffic rate, traffic shaping at the client side helps manage the flow of traffic and avoid TCP retransmissions by buffering the data. This allows for a more controlled and efficient use of the available bandwidth.

Traffic policing and traffic shaping have the following differences: Traffic policing directly discards packets with rates that are greater than the traffic policing rate. Traffic shaping, however, buffers packets with rates that are greater than the traffic shaping rate and sends the buffered packets at an even rate. Definitely Traffic shaping

It's A.) Traffic Shaping From Emmett Dulaney's Exam Cram N10-008: "The term traffic shaping describes the mechanisms used to control bandwidth usage on the network. With this, administrators can control who uses network bandwidth, for what purpose, and what time of day bandwidth can be used. Traffic shaping establishes priorities for data traveling to and from the Internet and within the network." And when searching online for Traffic prioritization (SimpleWAN.com), it provides a means to control the volume of traffic being sent into a network in a specified period, or the maximum rate at which the traffic is sent. It's used to optimize or guarantee performance, improve latency, and/or increase usable bandwidth for some kinds of packets by delaying other kinds. In this scenario, both A and D are the more likely choices but since Traffic Priortization is not listed in the CompTIA N10-008 objectives, it's A.

vceUP says the answer is Traffic prioritization...

The correct answer is A. Traffic shaping. Traffic shaping is a bandwidth management technique that allows the administrator to control the flow of traffic from the network to the client. The technique uses buffers at the client side to prevent TCP retransmissions from occurring when the ISP starts to drop packets of specific types that exceed the agreed traffic rate. Traffic shaping enables the administrator to prioritize traffic types and specify the maximum bandwidth that each traffic type can consume.

As I understood it, the buffer is not kept at the client side, but on the networking appliance. Still, A is correct, the other options don’t make sense.
