Refer to the exhibit. A retail company has around 500 branches across the U.S. The company is connected to the DC and DR routers through a Frame Relay cloud.

NEW QUESTION 86
You are implementing a multicast solution for a large service provider network. Which technology offers optimal routing of multicast traffic?
- A. Anycast RP
- B. MSDP
- C. PIM sparse mode
- D. PIM SSM
- E. Bidirectional PIM
Answer: D
Explanation:
Explanation/Reference:
Explanation:
SSM implies that the IP address of the source for a particular group is known before a join is issued. SSM in Cisco IOS is implemented in addition to PIM SM and co-exists with IP Multicast networks based on PIM SM. SSM always builds a sourcetree between the receivers and the source. The source is learned through an out-of-band mechanism. Because the source is known, an explicit (S, G) join can be issued for the source tree that obviates the need for shared trees and RPs. Because no RPs are required, optimal routing is assured; traffic travels the most direct path between source and receiver.
