1.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.
Wrong. 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
WRONG
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
There 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?
given 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
CORRECTION
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
1 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
Here 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.
1. **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.
Class-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.

I think the answers given are correct
I 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.
