CCIE Voice Test

Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. What is call-forward pattern used for?
Call forwarding between voip to voip (when CUBE is in play)
No it invokes the RSVP call agent on the IOS Router via SCCP message. i.e. use a Software MTP.
'Service Parameters --> Auto Answer Timer
CUCM OS Administration Settings --> NTP Servers

2. How do you configure a SIP Trunk? (router side)
TRUE
(config)#isdn switch-type primary-ni|(config)#network-clock-participate wic 0||(config)#controller t1 0/0/0|(config-controller)#pri-group timeslots 1-3|(config-controller)#no shut||(config)#voice service voip|(conf-voi-serv)#sip|(conf-serv-sip)#bind

1st the Subnet is recognized. (Device Mobility Info)|Then different Physical Locations are compared.

3. Does CUCM support RSVP natively?
Top Down means that channel 1 will be the first channel used to place outgoing calls.
Gw-priority command||#gatekeeper| #zone prefix CUCM 2... gw-priority 10 US_Trunk_2| #zone prefix CUCM 2... gw-priority 5 US_Trunk_1
