300-415 Question 101
Single answerYou are deploying a Cisco SD-WAN solution and need to onboard a new branch router to the SD-WAN overlay network. The router is located at a remote site with no direct access to vManage. Which deployment method should you use to ensure the router is successfully onboarded and establishes connectivity to the SD-WAN fabric?
- A
Use Plug-and-Play (PnP) with a ZTP (Zero Touch Provisioning) server
- B
Manually configure the device using CLI and upload the configuration file to vManage
- C
Deploy the router in controller-mode and allow automatic synchronization with vSmart
- D
Use vManage templates and vBond to push the configuration to the router
Show answer and explanation
Correct answer: A
Explanation
When deploying a new branch router in a Cisco SD-WAN solution, especially in remote locations, Plug-and-Play (PnP) with Zero Touch Provisioning (ZTP) is the most efficient method. This process automates the initial device provisioning and onboarding to the SD-WAN overlay network, leveraging vBond for authentication and vManage for configuration. This eliminates the need for manual configuration and ensures scalability.
- A. Correct.
Correct. Plug-and-Play (PnP) with a ZTP server is the recommended approach for onboarding remote sites in SD-WAN, as it minimizes manual intervention and automates the deployment process.
- B. Incorrect.
Incorrect. Manually configuring the router at a remote site can be error-prone and does not scale well for Cisco SD-WAN deployments.
- C. Incorrect.
Incorrect. Deploying the router in controller-mode is not a valid approach for initial onboarding in the SD-WAN solution.
- D. Incorrect.
Incorrect. vManage templates are used for centralized configuration management but require the router to already be onboarded to the SD-WAN fabric.
