300-435 Question 143
Select 3A network engineer is tasked with deploying a large-scale branch network using Cisco's Zero Touch Provisioning (ZTP). The devices must automatically download their configuration files and scripts upon connecting to the network for the first time. Which of the following are key requirements or steps to successfully implement ZTP?
- A
Ensure that the DHCP server is properly configured to provide option 67 pointing to the bootstrap file.
- B
Manually log in to each device to trigger the ZTP process.
- C
Host the configuration files and scripts on an accessible HTTP, HTTPS, or TFTP server.
- D
Ensure that the devices have access to the internet to download their configuration files.
- E
Validate that the device's factory-default configuration includes enabling ZTP mode.
Show answer and explanation
Correct answers: A, C, E
Explanation
Zero Touch Provisioning (ZTP) is designed to automate the deployment of new devices in a network. Key requirements include utilizing a properly configured DHCP server to provide necessary options like the bootstrap file location (option 67), ensuring the configuration files/scripts are accessible on a server, and verifying that devices are in their factory-default state with ZTP mode enabled. This eliminates the need for manual intervention and ensures seamless provisioning of devices.
- A. Correct.
Correct: DHCP option 67 is required to provide the location of the bootstrap file or script that the device will use to initiate the ZTP process.
- B. Incorrect.
Incorrect: ZTP is designed to be a completely automated process and does not require manual intervention on each device.
- C. Correct.
Correct: The configuration files and scripts must be hosted on a server accessible by the devices (HTTP, HTTPS, or TFTP servers are commonly used).
- D. Incorrect.
Incorrect: While internet access may be beneficial for updates or external services, ZTP does not inherently require internet access as long as the necessary files are available on a local server.
- E. Correct.
Correct: For ZTP to function, the device must be in its factory-default state, which typically includes ZTP mode being enabled. If ZTP mode is disabled, the process will not initiate.
