300-415 Question 191
Single answerYour organization has deployed a Cisco SD-WAN solution, and you are tasked with designing a topology that ensures all branch sites can communicate with each other directly, without traffic having to traverse through a centralized data center. Which topology would you choose to meet this requirement?
- A
Hub-and-Spoke
- B
Full-Mesh
- C
Partial-Mesh
- D
Point-to-Point
Show answer and explanation
Correct answer: B
Explanation
The Full-Mesh topology is the best choice for ensuring direct communication between all branch sites in a Cisco SD-WAN deployment. This topology eliminates the need for traffic to traverse through a centralized data center, enabling efficient and low-latency communication. Other topologies, such as Hub-and-Spoke or Partial-Mesh, introduce restrictions or additional hops that do not meet the stated requirement.
- A. Incorrect.
Hub-and-Spoke is a topology where all branch sites communicate via a central hub, usually a data center. This does not meet the requirement of direct communication between branches.
- B. Correct.
Full-Mesh allows all sites to communicate directly with each other, fulfilling the requirement for direct communication between branch sites.
- C. Incorrect.
Partial-Mesh allows some but not all sites to communicate directly. It may reduce complexity but does not guarantee direct connectivity for all branches.
- D. Incorrect.
Point-to-Point establishes a direct link between two sites but does not scale to multiple branch sites. This topology is unsuitable for ensuring direct communication across multiple branches.
