質問 # 184
In which mode does the Cisco Expressway act as a SIP-H.323 gateway only if one or more of the endpoints are locally registered?

正解：D


質問 # 185
For a Mobile and Remote Access deployment, which server's certificate must include the Unified registration domain as a Subject Alternate Name?

正解：B

解説：
The Expressway-E server certificate needs to include the following elements in its list of subject alternative names (SAN):
- Unified CM registrations domains
- XMPP federation domains
- IM and Presence chat node aliases (federated group chat)


質問 # 186
A company has enabled ICE to optimize call flows and improve video quality between their Cisco Collaboration endpoints internally and externally.
For which reason would you see activity on the TURN server when a call is established between two external endpoints?

正解：C

解説：
Those addresses (A, B, and C) populate the SIP SDP offer and answer as ICE candidates, and after the signaling has gone through, both endpoints will have the remote party ICE candidate addresses. It is at that point that the endpoints do a connectivity check by sending STUN messages to one another in an attempt to punch transport holes in the firewalls in order to establish media connectivity between peers.
