In which of the following scenarios is self-generated traffic QoS (sgt-QoS) useful?
EXP markings on transit control traffic are not set correctly.
The priority of all self-generated traffic needs to be lowered to allow all other traffic to take precedence.
The priority of various control packets requires special treatment throughout the network.
The BGP process is consuming too many CPU cycles and is impacting OSPF performance.
Which of the following statements describes an advantage of the DiffServ QoS model over the IntServ QoS model?
DiffServ reserves resources dynamically using the RSVP protocol.
DiffServ only requires packets to be classified into forwarding classes at the first network hop.
DiffServ provides granular differentiation and superior fairness because it processes traffic streams individually.
DiffServ is more scalable it treats traffic streams as aggregates.
