A .  Dense mode multicast requires explicit join messages from their members. B .  Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the  unwanted traffic. C .  Sparse mode multicast uses a pull model to send multicast traffic to where it is requested.   D .  Sparse mode uses reverse path forwarding （RPF） to prune off redundant flows. E .  The primary use of sparse mode multicast is for test labs and router performance testing.

A . RSVP itself provides bandwidth and delay guarantees. B . For RSVP to be end-to-end, all devices must support RSVP. C . RSVP reservations are maintained by a centralized reservations server. D . An RSVP compatible QoS mechanism must be used to implement guarantees according to RSVP reservations.

A .  An encapsulated， public class promotes re-use. B .  Classes that share the same interface are always tightly encapsulated. C .  An encapsulated class allows subclasses to overload methods， but does NOT allow overriding methods. D .  An encapsulated class allows a programmer to change an implementation without affecting outside code.

A . DPT/RPR uses a bi-directional ring consisting of two symmetric counter rotating fibre rings. B . DPT/RPR is defined in the IEEE 802.17 standard and it uses Token Bucket system to avoid collisions on the fiber. C . In DPT/RPR rings， data packets can be sent in one direction （downstream） and the corresponding control packets in the opposite direction （upstream），thus using both fibres concurrently to maximise bandwidth.
