XMPP Stanza Attribute

A.

The answer to this question is C. message.

In the context of Cisco Collaboration Core Technologies, XMPP (Extensible Messaging and Presence Protocol) is a communication protocol used for instant messaging, presence information, and contact lists. XMPP defines a format for exchanging messages between clients and servers, using XML-based stanzas.

A stanza is an XML data structure used to carry messages in XMPP. There are three types of stanzas in XMPP: message, presence, and IQ (Info/Query).

• Message stanzas are used for instant messaging and other types of communication where data needs to be exchanged between two or more parties.
• Presence stanzas are used for indicating a user's availability or status to other users.
• IQ stanzas are used for exchanging structured data between XMPP entities, such as requests for information or queries about a user's capabilities.

Therefore, in the context of XMPP, the attribute that contains an XMPP stanza is determined by the type of stanza being used. For message stanzas, the attribute that contains the XMPP stanza is the "message" element.
