To view an existing multiple instance element configuration you can go to the correct branch of the configuration tree and _______________.
High availability (HA) nodes identify one another by their __________ names.
The Net-Net 4000 is the source and destination for all signaling messages and media streams coming into and leaving the provider's network. Which two of the following SIP functions does it provide?
Which one of the following statements about H.323 networks is FALSE?
What component is responsible for rewriting RTP header information as it traverses the Net-Net 4000?
Which one of the following statements about the SIP-NAT is TRUE?
A __________ is a real-time interactive voice, video or multimedia communication that is established using IP signaling protocols such as SIP, H.323 or MGCP.
Best current practice for the initial turn-up of a secondary node in a highly available (HA) pair calls for the acquire-config command targeting the ____________________interface on the primary node.
In this scenario, the User Agents (UAs) are both SIP-enabled phones. What is the correct order of this basic SIP message flow?
1)The UAC initiates the session with an INVITE.
2)The UAS sends a 200 OK message indicating that the request has succeeded.
3)Media is exchanged bidirectionally.
4)The UAS sends a 100 Trying response back to the UAC
5)The UAC sends a BYE message. This is followed by a 200 OK final response message sent by the UAS.
6)The UAS sends a 180 Ringing message.
7)The UAC sends an ACK message confirming that it has received a final response to INVITE.

When associating network interfaces to a physical interface on the Net-Net 4000, the ___________ fields must contain the same unique ID.
A __________ is a logical definition on the Net-Net Session Director of a network or group of networks composed partly of devices that provide real-time communication sessions made up of signaling messages and potentially media flows.
In a high availability (HA) cluster, a network administrator could trigger a system switchover manually from the __________ Net-Net 4000 by issuing the notify berpd force command.
What sip-config option will suppress the inclusion of a registration cache cookie in the Contact header of messages forwarded?
__________ cookies are included by Sipd when it receives messages that are originally sourced from a device other then the configured External Proxy Address.
