   What is a characteristic of the Maximum Allocation Model (MAM) for MPLS TE bandwidth constraints?

   • AIt dynamically adjusts the maximum allocation based on real-time traffic.
   • BIt uses a hierarchical structure where higher classes can borrow from lower classes.
   • CIt provides strict bandwidth isolation between classes.
   • DIt allows bandwidth sharing between classes when one class is underutilized.

   How can the IPv6 flow label be used in a QoS architecture?

   • ATo indicate the priority of the packet.
   • BTo classify packets into flows for consistent QoS treatment.
   • CTo replace the DSCP field for QoS marking.

   In the Russian Doll Model (RDM) for MPLS TE bandwidth constraints, how is bandwidth allocated among classes?

   • AEach class has its own separate bandwidth pool that cannot be used by other classes.
   • BHigher-priority classes can preempt bandwidth from lower-priority classes.
   • CEach class has a fixed maximum allocation and no sharing occurs.
   • DBandwidth is shared equally among all classes.
