An organization requires that all API calls to its IOS XE devices be authenticated using a certificate-based mechanism rather than a shared password. Which authentication method should the engineer configure for RESTCONF?

HTTP Basic authentication with a local username and password

TLS client certificate authentication

OAuth2 token from an external identity provider

A team is developing a multi-vendor automation tool that must interact with both IOS XE and NX-OS devices. The tool must use a common data model to represent configuration. The team is considering using YANG models with RESTCONF. Which consideration is most important for the tool to work across both platforms?

Use JSON instead of XML for all requests

Ensure the YANG models are supported by both IOS XE and NX-OS

Configure the same username and password on all devices

Use the same HTTP method for all operations
