300-415 Question 104
Single answerAn enterprise is deploying Cisco SD-WAN routers at multiple branch locations. The IT team wants to ensure that all new branch routers are onboarded securely and automatically using a minimal configuration. Which deployment method should the IT team prioritize for this scenario?
- A
Manual configuration using CLI on each router
- B
Plug and Play (PnP) with Cisco vManage
- C
Bootstrap configuration using a USB drive
- D
Zero-Touch Provisioning (ZTP) with Cisco vManage
Show answer and explanation
Correct answer: D
Explanation
Zero-Touch Provisioning (ZTP) with Cisco vManage is the ideal deployment method for Cisco SD-WAN routers in large-scale environments. It streamlines the process by automatically onboarding routers to the SD-WAN fabric without requiring local configuration. This approach reduces manual effort, ensures security during deployment, and scales well for multiple branch locations.
- A. Incorrect.
Manual configuration using CLI requires a significant amount of manual effort and does not provide a secure or automated onboarding method for multiple routers.
- B. Incorrect.
Plug and Play (PnP) is a valid onboarding method, but it is typically used in scenarios involving Cisco PnP-enabled devices and specific workflows. It is not the preferred method for large-scale SD-WAN deployments.
- C. Incorrect.
Bootstrap configuration using a USB drive can be used, but it requires physical access to each router, which may not align with the goal of secure and automated deployment.
- D. Correct.
Zero-Touch Provisioning (ZTP) with Cisco vManage is the recommended method for onboarding SD-WAN routers securely and automatically with minimal configuration. It allows the routers to connect to the SD-WAN fabric and retrieve their configuration without manual intervention.
