300-435 Question 127
Select 3You are tasked with deploying a large-scale Cisco SD-WAN solution for a new branch office. To ensure efficient and automated Day 0 provisioning, you decide to preconfigure devices before they are shipped to the branch. Which method or methods would be most appropriate to achieve this goal?
- A
Use Plug and Play (PnP) to automatically onboard devices using the Cisco PnP Connect Cloud.
- B
Manually configure the devices by accessing them through the console port before deployment.
- C
Leverage Zero-Touch Provisioning (ZTP) to automatically download and apply configurations when devices are powered on.
- D
Create and apply a bootstrap configuration file that the device retrieves from a preconfigured TFTP server.
Show answer and explanation
Correct answers: A, C, D
Explanation
Day 0 provisioning methods aim to automate the initial configuration of devices to reduce manual effort and deployment time. Plug and Play (PnP), Zero-Touch Provisioning (ZTP), and bootstrap configuration files are all valid methods for automating this process. Manual configuration, while possible, is not considered a Day 0 provisioning method due to its lack of automation and scalability.
- A. Correct.
Plug and Play (PnP) is a recommended method for Day 0 provisioning as it allows devices to automatically connect to the network and retrieve their configuration from the Cisco PnP Connect Cloud.
- B. Incorrect.
Manually configuring devices through the console port is not an automated Day 0 provisioning method and is time-consuming, especially for large-scale deployments.
- C. Correct.
Zero-Touch Provisioning (ZTP) is a valid Day 0 provisioning method where devices automatically download their configuration files when they are powered on and connected to the network.
- D. Correct.
Using a bootstrap configuration file with a TFTP server is a valid automated provisioning method, where preconfigured settings can be applied to devices upon startup.
