300-435 Question 141
Single answerYou are tasked with deploying a large number of Cisco Catalyst switches in a new branch office. To streamline the process, you decide to use Zero-Touch Provisioning (ZTP). During the initial deployment phase, the switches are unable to download their intended configuration files from the ZTP server. After verifying that the devices are connected to the network and powered on, what is the most likely cause of this issue?
- A
The DHCP server is not configured to provide the option for the ZTP server address.
- B
The switches are not running the correct version of the operating system for ZTP.
- C
The ZTP server is using an incompatible protocol to deliver configuration files.
- D
The switches require manual intervention to enable ZTP mode.
Show answer and explanation
Correct answer: A
Explanation
The most common cause of ZTP failure during the initialization phase is an incorrectly configured DHCP server. ZTP depends on DHCP to provide the necessary information (such as the ZTP server's address) that allows switches to automatically download their configuration files. Ensuring the DHCP server is properly configured is critical to the success of ZTP deployment.
- A. Correct.
ZTP relies on the DHCP server to provide the necessary information, such as the ZTP server address, to the devices. If this is not configured, the devices cannot reach the ZTP server to retrieve the configuration files.
- B. Incorrect.
While the software version could impact certain features, ZTP is typically enabled by default on supported devices, and this is unlikely to be the root cause if the devices are compatible.
- C. Incorrect.
ZTP servers use standard protocols like HTTP, HTTPS, or TFTP to deliver configuration files. Protocol incompatibility is highly unlikely if the server is correctly configured.
- D. Incorrect.
ZTP is designed to work without manual intervention, so manual enabling is not typically required unless explicitly disabled.
