Implementing Cisco Collaboration Applications (CLICA) — Question 177
Which two protocols does the Cisco IM Presence service use to federate with external domains? (Choose two.)
Answer options
- A. XMPP
- B. SNMP
- C. SIP
- D. SCCP
- E. SMPP
Correct answer: A, C
Explanation
The correct answers are A (XMPP) and C (SIP) because these protocols are specifically designed for real-time communication and presence information exchange, which is essential for federating with external domains. Options B (SNMP), D (SCCP), and E (SMPP) do not serve this purpose, as they are used for other types of network management and communication.
