Oct 28, 20221.classification 2.cloud based weighted fair queueing = "to guarantee a minimum amount of bandwidth to each class" OCG vol 2 ch11 3.policing = Discard messages 4.congestion 5.shaping = que traffic for non priority packets My distain of Cisco grows everyday.

Dec 21, 2022I think 5 should be policing not shaping.

Apr 23, 2023But with shaping, congestion is still there, shaping just put the traffic into a queue, so it cannot prevent congestion

Sep 19, 2023I think shaping is "prevents congestion by reducing the flow of outbound traffic" i think key word is outbound as shaping only works in egress

Nov 16, 2023Wrong. 5 is 100% policing. Here's Cisco's definition: "Traffic Policing--This feature allows you to limit the input or output transmission rate of a class of traffic based on user-defined criteria." https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_dfsrv/configuration/15-mt/qos-dfsrv-15-mt-book/qos-dfsrv.html

Sep 19, 2022Shouldn't cloud-based wighted fair queueing and policing be swapped?

Oct 13, 2022Class-based weighted fair queueing (CBWFQ) extends the standard WFQ functionality to provide support for user-defined traffic classes. For CBWFQ, you define traffic classes based on match criteria including protocols, access control lists (ACLs), and input interfaces. https://www.cisco.com/en/US/docs/ios/12_0t/12_0t5/feature/guide/cbwfq.html#wp17641 I think the answers given are correct

Oct 20, 2022I do not believe that "Policing" guarantees traffic bandwidth. Its used by ISP to avoid oversuscription. It drops traffic or remarks it, i dont think its intended to guarantee anything. Correct me if im wrong, but i agree with Anon.

Aug 14, 20231. **classification**: Categorizes packets based on the value of a traffic descriptor. 2. **class-based weighted fair queueing**: Guarantees minimum bandwidth to specific traffic classes when an interface is congested. 3. **shaping**: Prevents congestion by reducing the flow of outbound traffic. 4. **congestion**: Outcome of overutilization. 5. **policing**: Uses defined criteria to limit the transmission of one or more classes of traffic.

Oct 23, 2023Here are the matches for the QoS terms with their definitions: 1. **Classification**: Categorizes packets based on the value of a traffic descriptor¹. 2. **Cloud-based weighted fair queueing**: Guarantees minimum bandwidth to specific traffic classes when an interface is congested¹⁵. 3. **Shaping**: Prevents congestion by reducing the flow of outbound traffic¹¹. 4. **Congestion**: Outcome of overutilization⁵. 5. **Policing**: Uses defined criteria to limit the transmission of one or more classes of traffic⁸.

Feb 9, 2025WRONG Categorizes packets based on the value of a traffic descriptor = Classification Guarantees minimum bandwidth to specific traffic classes when an interface is congested = cloud based weighted fair queueing Prevents congestion by reducing the flow of outbound traffic = Shaping Outcome of overutilization = Congestion Uses defined criteria to limit the transmission of one or more classes of traffic = Policing

Mar 19, 20241 classification 2 CBWFQ 3 policing 4 Congestion 5 shaping policing cant be at 5 because it doesnt use any queues, but at 3 it does prevent congestion in the service provider network. the wording on the answers is misleading though

Mar 24, 2024given answers are incorrect, they must be: Categorizes packets based on the value of a traffic descriptor:: Classification Guarantees minimum bandwidth to specific traffic classes when an interface is congested:: Class based weighted fair queueing Prevents congestion by reducing the flow of outbound traffic:: Shaping Outcome of overutilization:: Congestion Uses defined criteria to limit the transmission of one or more classes of traffic:: Policing

May 13, 2024CORRECTION Categorizes packets based on the value of a traffic descriptor == Classification Guarantees minimum bandwidth to specific traffic classes when an interface is congested == Shaping Prevents congestion by reducing the flow of outbound traffic == Policing Outcome of overutilization:: Congestion Uses defined criteria to limit the transmission of one or more classes of traffic == Class based weighted fair queueing

Oct 19, 2024There doesn't exist something called "CLOUD-based weighted fair queueing". It's CLASS-based! It's just CBWFQ, which guarantees minimum bandwidth to specific class of traffic. The given answer is wrong. Moreover, the option in the question is wrong as well. Are these really CCNA questions? Or just fake questions posted by Cisco to confuse learners so that they fail the exam and pay the fee again?
