Designing Cisco Enterprise Networks (ENSLD) — Question 231
A company’s branch location uses redundant routers and links for connectivity to the headquarters. Also, to use the entire available bandwidth, the branch uses a dynamic routing protocol. An architect must design a multicast streaming solution to avoid RPF check failures because of the current network design. Which deployment model must the architect choose?
Answer options
- A. PIM-BSR
- B. BIDIR-PIM
- C. PIM-SM
- D. PIM-SSM
Correct answer: B
Explanation
The correct answer is BIDIR-PIM, which is designed for scenarios with redundant paths and can efficiently support multicast traffic without RPF check issues. PIM-BSR, PIM-SM, and PIM-SSM do not adequately handle the complexities introduced by the redundant links in this specific network environment.
