How are authentication credentials sent in a Cisco APIC REST API authorization request?

Correct Answer: B 🗳️
Authentication to the REST API for username/password-based authentication uses a special subset of request URIs, including aaaLogin, aaaLogout and aaaRefresh as the Dn target of a POST operation. Their payloads contain a simple XML or JSON payload containing the MO representation of an aaaUser object with attributes name and pwd defining the username and password, for example: <aaaUser name=admin pwd=insieme/>. The response to the POSTs will contain an authentication token as both a Set-Cookie header as well as an attribute to the aaaLogin object in the response named token, for which the XPath is / imdata/aaaLogin/@token if encoded as XML. Subsequent operations on the REST API can use this token value as a Cookie named "APIC-cookie" to have future requests authenticated.

A host can be either an appliance, server or virtual machine where Cisco APIC-EM has been installed. Within the hosts are the Linux containers running instances of the Grapevine clients. The Grapevine clients run the different services. The Grapevine root runs as an application on the host itself and not in any Linux containers.
