200-901 Infrastructure and Automation Practice Question
An organization implements zero-touch provisioning (ZTP) for new Cisco routers using DHCP and TFTP. The provision script is not being executed even though the device obtains an IP address. The DHCP server logs show the option 67 (bootfile-name) and option 150 (tftp-server) are set. What is the most probable reason?
⚠ Common exam trap
Cisco often tests the distinction between DHCP options being configured correctly on the server versus the actual file availability on the TFTP server, leading candidates to incorrectly blame network connectivity (option C) or DHCP server authority (option A) when the real issue is a simple filename mismatch.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The script file name in option 67 does not match the actual file on the TFTP server
The most common reason for a ZTP script not executing after a device obtains an IP address is a mismatch between the bootfile name specified in DHCP option 67 and the actual filename on the TFTP server. Even if the DHCP server logs show option 67 and 150 are set, the router will attempt to download the file specified in option 67; if that file does not exist or is named differently on the TFTP server, the download fails and the script is not executed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The DHCP server is not authoritative
Why it's wrong here
Authoritative status does not affect ZTP script execution.
- ✓
The script file name in option 67 does not match the actual file on the TFTP server
Why this is correct
A mismatch in filename prevents the device from loading the script.
- ✗
The TFTP server IP is unreachable from the router
Why it's wrong here
If the TFTP server were unreachable, the device would not obtain the script, but DHCP options are set correctly.
- ✗
The router does not support ZTP
Why it's wrong here
Most modern Cisco routers support ZTP.
