Cisco Quality of Service (QoS) Sample Questions:

1. Which three characteristics are drawbacks to the use of a best-effort with over-provisioning backbone design? (Choose three.)

A) It requires complex QoS mechanisms at the network edge.
B) Denial of Service attacks on one service can affect all network traffic.
C) The design uses a different over-provisioning ratio for the different traffic classes.
D) Unplanned network failures can cause unexpected congestion in the network.
E) It requires complex QoS mechanisms at the network core.
F) The design costs more to implement than a DiffServ backbone.

2. Refer to the exhibit. QPPB is being used by the service provider (AS30). The table-map and route-map called "important" are implemented on router POP A.
The command bgp-policy destination ip-prec-map is applied to the interface between POP A in AS30 and NAP (AS40).
Which QoS action would have to be applied on POP B in AS30 to ensure that the traffic from the NAP (AS40) to the customer (AS20) will be marked with an IP precedence of flash?

A) Traffic from AS20 must be automatically marked via an inbound QoS map on POP B, resulting in the community attribute set to10:50.
B) Traffic from AS20 must have the community attribute set to10:50 in a route-map, and send-community must be specified.
C) No actions are needed. Traffic must be marked in AS20 by the customer as10:50 before it arrives at the service provider.
D) Traffic from AS20 must have the extended community attribute set to10:50 in a route-map, and send-community extended (or send-community both) must be specified.

3. Refer to the exhibit. Why would applying the limit-interactive policy-map to the fa0/0 interface as shown below cause an error?
interface fa0/0 service-policy input limit-interactive

A) The interactive class-map has not been configured.
B) Class-based policing can only be applied in the output direction.
C) The interactive traffic class is missing the bandwidth {kbps} command.
D) There is already an output service-policy defined on the fa0/0 interface.
E) TCP header compression can only be applied in the output direction.

4. What describes the use of best-effort service with overprovisioning?

A) ensuring quality of service by providing more than the aggregate bandwidth required
B) ensuring constant availability by provisioning multiple paths through the network
C) ensuring availability and quality of service by always provisioning key services across at least two service provider networks
D) ensuring quality of service by being able to load balance across links in times of congestion
E) ensuring quality of service by deploying sophisticated prioritization and congestion management mechanisms
