11. Delivery Flashcards
1
Q
What are the primary types of delivery methods in networking?
A
Unicast, multicast, broadcast, and anycast.
2
Q
How does multicast differ from broadcast?
A
Multicast sends data to a specific group of recipients, while broadcast sends
data to all devices in a network.
3
Q
What is Anycast, and what is it commonly used for?
A
Anycast delivers data to the nearest member of a group, commonly used for
DNS and content delivery networks.
4
Q
Why is broadcast communication inefficient in WANs?
A
Because it generates excessive traffic and lacks the scalability needed for
large networks.
5
Q
What is multicast tunneling, and why is it necessary?
A
Multicast tunneling encapsulates multicast packets in unicast packets to
traverse networks that do not support native multicast.
