Which two protocols are used in Cisco Jabber call control signaling and instant messaging? (Choose two.)

XMPP (Extensible Messaging and Presence Protocol) is the protocol Cisco Jabber uses to exchange instant messages and presence status with the Cisco IM and Presence Service.

TCP is a transport-layer protocol that carries application data but is not itself a Jabber-specific signaling or messaging protocol.

SIP/SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) is used by Cisco Jabber to establish and manage call control sessions with Cisco Unified Communications Manager.

SSH is a secure remote-access protocol used for device administration and has no role in Jabber call control or instant messaging signaling.

SCCP (Skinny Client Control Protocol) is a Cisco-proprietary protocol used by certain IP phones to register with CUCM, but Jabber clients use SIP for call control, not SCCP.
