Question 6 of 61

You configured the Session Agent Group (SAG) element. You want the Session Agent to be selected in the order in which they are listed in the destination list, with each agent selected in turn, one per session.

How would you accomplish this?

    Correct Answer: D

    To accomplish selecting the Session Agent in the order in which they are listed in the destination list, with each agent selected in turn, one per session, you should navigate to the session-agent configuration element and set the strategy parameter to roundrobin. The roundrobin strategy ensures that each agent is selected in sequence, distributing load evenly across the listed agents.

Question 7 of 61

Which action triggers the 180 Ringing response in a User Agent Client (UAC)?

    Correct Answer: B

    The action that triggers the 180 Ringing response in a User Agent Client (UAC) is the generation of a remote ring-back tone. This occurs when the called party is alerted, and the UAC is informed that the called party is being rung. This response indicates that the call setup is proceeding as expected and that the remote endpoint is being notified of the incoming call.

Question 8 of 61

Which two statements describe the functions of Session Border Controllers? (Choose two.)

    Correct Answer: B, E

    Session Border Controllers (SBCs) are session-aware devices that enable control of end-to-end interactive communications across IP network borders, which makes option B correct. Additionally, they provide signaling proxy functions for SIP, H.323, and MGCP, including access control, signaling constraints, and topology hiding, making option E correct as well. They do not replace typical edge routers and firewalls, nor are they based on the Windows operating system, and they don't provide routing functions for IP, TCP, and SMTP using application parameters.

Question 9 of 61

You are configuring a sip-interface configuration element. You encounter the error message: Error 409 saving configuration SipInterface.

Identify the cause of the error.

    Correct Answer: D

    The error message 'Error 409 saving configuration SipInterface' indicates a conflict, typically due to an attempt to create a duplicate entry. Specifically, in the context of configuring a SIP interface, this error is most likely caused by attempting to create a sip-interface element with the same realm-id parameter value as another existing sip-interface element. This is because each SIP interface must have a unique realm-id to avoid conflicts.

Question 10 of 61

You are configuring access rules in a Session Border Controller Peering architecture.

Which two configuration steps are required to allow access only from User Agents (UAs) configured as session agents? (Choose two.)

    Correct Answer: B, D

    To allow access only from User Agents configured as session agents, the following steps are required. First, navigate to the session-agent configuration element and set the ip-address parameter to the IP subnet of your trusted User Agent (UA), ensuring that only specific trusted UAs are recognized. Second, navigate to the sip-port configuration element and set the allow-anonymous parameter to agents-only, which restricts access to only those UAs identified as session agents.
