Question 381
 
                            
                            
                                Where in Cisco UCM is restrictions on audio bandwidth configured?
Question 382
 
                            
                            
                                How many minutes does it take for automatic fallback to occur in a Presence Redundancy Group if the primary node lost a critical service?
Question 383
 
                            
                            
                                An engineer is going to redesign a network, and while looking at the QoS configuration, the engineer sees that a portion of the network is marked with AF42. Which type of traffic is marked with this tag?
Question 384
 
                            
                            
                                Why does Cisco UCM use DNS?
Question 385
 
                            
                            
                                An administrator is configuring a new Cisco UCM with PSTN capabilities. Due to bandwidth constraints, audio compression is used on the codec. DTMF must work as expected because the customer is calling many call centers where the users must select options in the call. Where is DTMF out-of-band in a CCM 12.5 with SIP-based gateway configured?
Question 386
 
                            
                            
                                A high-speed network is often configured with a five-class QoS model. Which classes are used in the model?
Question 387
 
                            
                            
                                Which characterstic of distributed class- based weighted fair queueing addresses jitter prevention?
Question 388
 
                            
                            
                                What are two characteristics of jitter in voice and video over IP communications? (Choose two.)
Question 389
 
                            
                            
                                What are two features of Cisco Expressway that the customer gets if Expressway-C and Expressway-E are deployed?(Choose two.)
Question 390
 
                            
                            
                                Exhibit.
Refer the exhibit. A collaboration engineer needs to replace the original, single NTP
server that was configured during the inital install of a Cisco UCM server. What is the first
step to accomplish this task?
