If you only have the site name, you can retrieve the site identifier by making an API call to /dna/intent/api/v1/site. This call will provide you with the necessary information to properly add the device to the network.

 Cisco IOS XE Software supports two main data modeling languages for its network programmability interface: RESTCONF and NETCONF. RESTCONF provides an API that uses HTTP methods for a programmatic interface over HTTP/HTTPS web services with support for both JSON and XML data formats. On the other hand, NETCONF is a protocol defined by the IETF that also provides a programmatic interface but only supports XML as its data format. Therefore, the statement that RESTCONF supports JSON and XML while NETCONF supports only XML is true. References: Automating Cisco Enterprise Solutions Official Cert Guide

 Python virtual environments should be used in cases where there are conflicting Python package versions across multiple projects (Option B) to ensure each project can have its own set of dependencies. Additionally, they are beneficial when starting a new project that requires a clean development environment (Option E), as it allows for a controlled setup without interference from other projects’ dependencies. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )
