Advanced Guide: 300 075 dump
The article at Testaimer.com going over http://www.testaimer.com/300-075-test is very comprehensive.
Q21. You recently implemented call redundancy at a new remote site, and users report that calls are dropped when the remote site supposedly is in SRST. Which two actions must you take to troubleshoot the problem? (Choose two.)
A. Confirm that SRST is configured on the voice gateway.
B. Confirm that the site has an SRST reference that is correctly associated with the Cisco Unified Communications Manager group.
C. Confirm that a calling search space is assigned to the voice gateway in Cisco Unified Communications Manager.
D. Confirm that the site devices are associated with a Cisco Unified Communications Manager group and that four Cisco Unified Communications Manager servers are available.
E. Check the Region settings in Cisco Unified Communications Manager.
F. Restart Cisco Unified Communications Manager services to confirm that the server is working correctly.
Q22. What is a prerequisite of AAR deployment?
A. You must have a single distributed call processing deployment.
B. Calls must be manually rerouted through the PSTN or other networks when Cisco Unified Communications Manager blocks a call due to insufficient location bandwidth.
C. Calls must be automatically rerouted through the PSTN or other networks when Cisco Unified Communications Manager blocks a call due to insufficient location bandwidth.
D. Clustering must be implemented over the WAN.
E. You must have a centralized call processing deployment.
Q23. The network administrator of Enterprise X receives reports that at peak hours, some calls between remote offices are not passing through. Investigation shows no connectivity problems. The network administrator wants to estimate the volume of calls being affected by this issue. Which two RTMT counters can give more information on this? (Choose two.)
Q24. When a SIP trunk is added for Call Control Discovery, which statement is true?
A. The SIP trunk is added by selecting SIP Trunk and SIP Protocol. The Enable SAF check box should be selected.
B. The SIP trunk is added by selecting SIP Trunk and SIP Protocol. The Trunk Service Type should be Call Control Discovery.
C. The SIP trunk is added by selecting Call Control Discovery Trunk and then selecting SIP as the protocol to be used.
D. The SIP trunk is added by selecting SIP Trunk and SIP Protocol. The destination IP address field is configured as ‘SAF’ to indicate that this trunk is used for SAF.
Q25. While configuring Call Survivability in Cisco Unified Communications Manager, what step is mandatory to reach remote sites while in SRST mode?
A. Enable Cisco Remote Site Reachability.
B. Configure CFUR.
C. Enable the SRST checkbox in the MGCP gateway.
D. Configure the H.323 gateway for SRST in Cisco Unified Communications Manager.
E. Enable the Failover Service parameter.
Incorrect Answer: A, C, D, E Call Forward Unregistered (CFUR) functionality provides the automated rerouting of calls through the PSTN when an endpoint is considered unregistered due to a remote WAN link failure Link: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/models.html
Q26. When you configure Cisco Unified Communications Manager, you need to configure the router for Survivable Remote Site Telephony in case the Cisco Unified Communications Manger stops working. On which two factors would the number of IP phones and Directory Numbers that can register to the SRST router depend? (Choose two.)
A. The protocol that is used in Cisco Unified Communications Manager
B. Cisco Unified Communications Manager version
C. Cisco IOS Software version
D. WAN link bandwidth
E. capacity of the Cisco Media Convergence Server
F. router platform
Q27. Refer to the exhibit.
Which trunks would be most suitable for Connection Y?
A. an H.225 trunk (gatekeeper-controlled)
B. intercluster trunk (gatekeeper-controlled)
C. a SIP trunk on the U.S. cluster and an intercluster trunk on the remote cluster
D. intercluster trunk (nongatekeeper-controlled)
E. No extra connections are required. As long as IP connectivity exists, you need only configure a route pattern for each site. The Cisco Unified Communications Manager will automatically forward the calls over the WAN if the destination directory number is not registered locally.
Q28. You are entering the description for the Service Advertisement Framework forwarder.
Which three characters should you avoid entering in the description? (Choose three.)
A. < >
Q29. How can the location setting be modified to resolve poor call quality?
A. No adjustment to location setting is needed
B. Mark the bandwidth between the locations as unlimited
C. Decrease the audio bandwidth setting
D. Remove the audio bandwidth setting
Q30. The network administrator at Enterprise X is creating the guidelines for a new IPT deployment consisting of a large number of remote offices. Every user within Enterprise X is assigned a directory number of 5 digits. Which option might cause an issue in a multisite deployment?
A. Overlapping DID ranges are allocated to each site.
B. The maximum number of IP phones are in use at each remote site.
C. MoH cannot be provided for the remote sites.
D. All media streams are necessarily routed through the central office for calls to establish correctly.
