300-415 Question 41
Single answerAn enterprise is deploying a Cisco SD-WAN Multi-Region Fabric design to scale its network and simplify management. The network consists of two regions, Region 1 and Region 2, each with its own controllers. The enterprise wants to ensure that traffic between regions is optimized and follows the shortest path. Which component is required to facilitate communication between these two regions?
- A
A centralized vSmart controller shared between both regions
- B
A configured Regional vBond orchestrator for each region
- C
A manual static route configuration between regional edges
- D
A designated data plane hub site to serve as a Transit Router between regions
Show answer and explanation
Correct answer: D
Explanation
In a Cisco SD-WAN Multi-Region Fabric, communication between regions is typically optimized by using a designated data plane hub site, referred to as a Transit Router. This router ensures that traffic between regions follows the shortest path and is efficiently routed, without relying on manual configurations or centralized controllers. This design improves scalability and simplifies management.
- A. Incorrect.
A centralized vSmart controller is not necessary in a Multi-Region Fabric design, as each region can have its own vSmart controller. Inter-region communication does not rely on a shared vSmart but rather on the data plane.
- B. Incorrect.
The vBond orchestrator is responsible for initial device onboarding and establishing secure connections. It does not directly handle inter-region traffic optimization.
- C. Incorrect.
While static routes could theoretically be configured, this manual approach does not scale well and is not recommended in a Multi-Region Fabric design.
- D. Correct.
A designated data plane hub site, also called a Transit Router, is a crucial component in a Multi-Region Fabric. It facilitates optimized communication between regions by routing traffic efficiently.
