Question

A network engineer is configuring RESTCONF over HTTPS on a Cisco IOS-XE perimeter router to allow a Python automation script to push configuration changes. The script authenticates successfully and can perform GET operations, but every PUT and POST request returns an HTTP 405 Method Not Allowed error. The engineer confirms the user account has privilege level 15. What is the most likely cause?

Accepted Answer

The device has 'restconf' enabled but the target YANG data node is operational (read-only) rather than configuration data

Answer

The HTTPS server certificate has expired, blocking write operations only

Answer

The AAA method list is missing a command authorization statement for RESTCONF

Answer

The Accept header in the script requests XML while the device only supports JSON for writes
