300-435 Question 124
Select 2A network engineer is tasked with provisioning a new branch office router with minimal manual intervention. The router needs to automatically download its configuration file and join the network securely upon being powered on. Which of the following Day 0 provisioning methods can achieve this goal?
- A
Plug and Play (PnP)
- B
Zero-Touch Provisioning (ZTP)
- C
Dynamic Host Configuration Protocol (DHCP) Option 82
- D
Network Configuration Protocol (NETCONF)
Show answer and explanation
Correct answers: A, B
Explanation
Day 0 provisioning methods focus on automating the initial setup of network devices with minimal manual effort. Plug and Play (PnP) and Zero-Touch Provisioning (ZTP) are two effective approaches for automating the onboarding of new devices like routers. PnP is Cisco-specific, while ZTP is vendor-neutral. Other options, like DHCP Option 82 and NETCONF, are not directly designed for Day 0 provisioning but may play a role in specific workflows.
- A. Correct.
Plug and Play (PnP) is a Cisco-specific Day 0 provisioning method that allows devices to automatically connect to the network, securely retrieve their configuration, and register with the management system without manual intervention.
- B. Correct.
Zero-Touch Provisioning (ZTP) is a vendor-neutral method that facilitates automatic configuration and deployment of devices upon booting using a DHCP or TFTP server.
- C. Incorrect.
DHCP Option 82 is used for relay agent information in DHCP communications, but it is not a full-fledged Day 0 provisioning method by itself. It is a supporting mechanism in some provisioning workflows.
- D. Incorrect.
Network Configuration Protocol (NETCONF) is a protocol used for configuration management and operations but is generally employed for Day 1 or Day 2 operations rather than Day 0 provisioning.
