REST APIs and Data Models

A network engineer is automating the configuration of a new VLAN on a Cisco Catalyst 9000 switch using RESTCONF. The engineer sends a PUT request to the URI 'https://switch/restconf/data/Cisco-NX-OS-device:Native/VlanList' with a JSON payload containing the VLAN details. The switch responds with a 405 Method Not Allowed error. What is the most likely cause of this error?

An engineer is using a Python script to retrieve interface statistics from a Cisco IOS-XE device via the REST API. The script sends a GET request to 'https://device/restconf/data/ietf-interfaces:interfaces/interface=GigabitEthernet1/statistics' and receives a 404 Not Found response. The interface exists and is operational. What is the most likely issue?

A network team is using Ansible with the iosxr_config module to push configuration changes to a Cisco IOS-XR router. The playbook uses the REST API via the 'ansible_connection: restconf' setting. The engineer notices that the changes are applied but the playbook reports 'changed: false' even when changes were made. What is the most likely reason for this behavior?

An engineer is developing a script to automate the backup of running configurations from multiple Cisco IOS-XE devices using RESTCONF. The script sends a GET request to 'https://device/restconf/data/Cisco-IOS-XE-native:native/configuration' and receives a 501 Not Implemented error. What is the most likely cause?

A network engineer is using the Cisco DNA Center REST API to retrieve the list of network devices. The engineer sends a GET request to '/dna/intent/api/v1/network-device' and receives a 400 Bad Request response. The API documentation indicates that the request requires a query parameter 'siteId'. What should the engineer do to resolve the issue?

An engineer is using a Python script to configure a new VLAN on a Cisco Nexus 9000 switch using the NX-API REST API.

The API returns a 429 Too Many Requests error. What should the engineer do to resolve this issue?

An engineer is using the Cisco SD-WAN vManage REST API to retrieve the list of WAN edge devices. The engineer sends a GET request to 'https://vmanage/dataservice/device' and receives a 401 Unauthorized error. The engineer has already obtained a JSESSIONID cookie by authenticating with the API. What is the most likely cause of the error?
