Question 6.
You are working in a service provider voice NOC supporting a national VoIP network. The network underwent a capacity expansion that added voice bearer trunks to a newly deployed media gateway. After the new trunks were configured and placed into live service, the service desk began to receive complaints from end customers that their VoIP service is not working for certain calls. The service desk is unable to resolve the problem and due to increasing troubles coming in, they escalate to you.

Assuming that all physical layer option settings are verified to match carrier-provided specifications, which action should you take to isolate the problem before escalating to the PSTN PTT carrier?

A. Verify IP connectivity between the media gateway controller and the media gateway.
B. Fail over the media gateway to its backup.
C. Identify which trunks are not functioning.
D. Verify that SIP versions are compatible between the media gateway controller and the media 
    gateway

Answer: C

Explanation:  
reason: The question is saying that the service is not working for certain calls which means that ip connectivity might be fine and the fail over is also working.. Similarly, if sip version are not compatible there would be a problem with all calls. So trunks problem might be the answer

What is the main difference between an SNMP trap and a syslog message?

A. SNMP traps are secure, whereas syslog messages are not.
B. SNMP traps are triggered during network outages, whereas syslog messages are 
    Informational only.
C. SNMP traps are forwarded to EMS systems, whereas syslog messages are forwarded to any 
    NMS system.
D. SNMP traps are formally defined in a MIB, whereas syslog body contents are not formally 
    defined.
