Which two protocols does Jabber use to achieve Presence status? (Choose two.)

SIP/SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) extends SIP with SUBSCRIBE and NOTIFY methods that enable Jabber to exchange presence state with SIP-based endpoints and the IM and Presence Service.

XMPP (Extensible Messaging and Presence Protocol) is the native protocol of the IM and Presence Service and is used by Jabber to communicate availability and presence states, as well as to send instant messages.

SCCP (Skinny Client Control Protocol) is a Cisco proprietary signaling protocol used for call control between IP phones and CUCM, and has no role in presence.

MGCP (Media Gateway Control Protocol) is used to control media gateways at the PSTN boundary and is unrelated to presence or instant messaging.

SOAP is a web services messaging protocol used for application integration and is not a presence or real-time communications protocol used by Jabber.
