300-435 Question 126
Single answerAn enterprise has just purchased a fleet of Cisco switches and needs to provision them across multiple branch offices with minimal manual intervention. The IT team wants to ensure the switches automatically download their configurations upon boot, based on their serial numbers. Which Day 0 provisioning method would be the most appropriate for this scenario?
- A
Plug and Play (PnP)
- B
Network Configuration Protocol (NETCONF)
- C
Bootstrap configuration using DHCP Option 66
- D
Ansible Playbook
Show answer and explanation
Correct answer: A
Explanation
Plug and Play (PnP) is a Cisco-specific solution for Day 0 provisioning that is ideal for environments requiring zero-touch setup of devices. By leveraging PnP, devices can automatically register with a PnP server and receive their configurations based on identifying factors such as serial numbers, making it the most suitable choice for this use case.
- A. Correct.
Plug and Play (PnP) is the correct method for this scenario as it is designed for zero-touch provisioning of Cisco devices. It allows devices to automatically download their configurations and images based on identification information like serial numbers.
- B. Incorrect.
NETCONF is a network configuration protocol used for managing devices, but it is not typically used for Day 0 provisioning in an automated, zero-touch manner as described in the scenario.
- C. Incorrect.
DHCP Option 66 can be used for basic bootstrap configuration, but it does not provide the robust, serial number-based provisioning required in this scenario.
- D. Incorrect.
Ansible Playbooks are used for configuration management and automation after devices are set up and reachable, but they are not designed for zero-touch Day 0 provisioning.
