Question No. 3

Which of the following statements about the DiffServ and IntServ QoS models is FALSE?

AIntServ uses a protocol like RSVP to provide QoS guarantees on a per-flow basis.

BDiffServ groups multiple microflows into bigger streams called macro flows.

CIntserv requires that network routers allocate resources for thousands of individual flows.

DDiffserv classifies packets into forwarding classes only at the first network hop.

Question No. 4

Which of the following statements about network QoS policies is FALSE?

AClassification rules must specify both an FC and a profile for the packets.

BA network policy is applied at a physical port.

CClassification is performed with behavior-aggregate statements only.

DMatch criteria can be chosen from dot1p, DSCP, and EXP fields in the packet.

Question No. 5

Which of the following statements are TRUE when discussing self-generated traffic QoS? (Choose two)

AIn order to mark Layer 2 traffic, sgt-qos will set various ToS bits.

BDSCP bits can be set per application, per routing instance.

CThe DSCP marking stays nc1 for all applications. Only the internal FC is manipulated across different applications.

DIn order to mark Layer 2 self-generated traffic, network interfaces must be set to dot1Q.

EThe internal forwarding class for self-generated traffic is set once and applied to the base router and all VPRN instances.
