Question No: 222
When an H.323 trunk is added for Call Control Discovery, which statement is true?
The H.323 trunk is added by selecting Inter-Cluster Trunk (Non-Gatekeeper Controlled) and Device Protocol Inter-Cluster Trunk. The Enable SAF check box should be selected in the trunk configuration.
The H.323 trunk is added by selecting Inter-Cluster Trunk (Non-Gatekeeper Controlled) and Device Protocol Inter-Cluster Trunk. The Trunk Service Type should be Call Control Discovery.
The H.323 trunk is added by selecting Call Control Discovery Trunk and then selecting
H.323 as the protocol to be used.
The H.323 trunk is added by selecting H.323 Trunk, and selecting Inter-Cluster Trunk as the Device Protocol. The destination IP address field is configured as ‘SAF’ to indicate that this trunk is used for SAF.

Question No: 223
During device failover to the secondary Cisco Unified Communications Manager server, how does the phone recognize that the primary server is back?
The secondary server keeps sending keepalive message to the primary server and when it succeeds, it unregisters the phones to force them to register to the primary.
When the primary server goes online, it sends out an quot;ALIVEquot; message via broadcast so that the phones re-register.
The phones never re-register with the primary server until the active (secondary) one goes down.
The phone sends keepalive messages to the primary server frequently and when it succeeds, the phone re-registers with it.
Question No: 224
You are the Cisco Unified Communications Manager in Certpaper.com. After you add the Tcl paramspace command, the application can .

Question No: 225
In a Centralized Call processing architecture, you have deployed Extension Mobility (EM) feature. After the deployment of EM, when one of the end-users tries to login to the IP phone, the Error 25 is displayed on the screen. What three things should you do to resolve this issue? (Choose three.)
upgrade the firmware of the IP Phone to the latest version
activate EM feature service under Cisco Unified Serviceability
associate EM Device profile with the end-user
subscribe the MAC address of the IP Phone to EM Service
update EM Phone Service URL to point to the publisher
subscribe device profile to EM phone service in case the enterprise subscription of EM Service is disabled
Question No: 226
An engineer is configuring URI calling within the same cluster. Which four actions must be taken to accomplish this configuration? (Choose four.)
Configure SIP route patterns.
Configure the directory URI partition and calling search space.
Associate the directory URIs to directory numbers.
Activate the URI service in Cisco Unified Serviceability.
Configure SIP trunk.
Assign directory URIs to users.
Configure the SIP profile.
Configure the URI service parameters.
Question No: 227
Enabling authentication and encryption for CTI, JTAPI, and TAPI applications requires which two tasks? (Choose two.) (SourcE. Configuring Cisco IP Telephony Authentication and Encryption)
Enter the encryption key into the application.
Set up an IPsec association between the application and Cisco Unified CallManager.
Configure related security parameters in the CTI, JTAPI, and TAPI application.
Add the application user or end users to the Standard CTI Secure Connection user group, Standard CTI Allow Reception of SRTP Key Material user group, and Standard CTI Enabled user group.
Explanation: Incorrect answer: AB
You must also add the application users or the end users to the Standard CTI Secure Connection user group in Cisco Unified Communications Manager Administration to enable TLS for the application. After you add the user to this group and install the certificate, the application ensures that the user connects via the TLS port.

Question No: 228
Which statement about AAR functionality is true?
AAR reroutes calls through the PSTN upon WAN failure.
AAR reroutes calls through the PSTN when Cisco Unified Communications Manager CAC blocks a call.
AAR reroutes calls through the WAN when the PSTN connection fails.
AAR reroutes calls to another phone number when a Cisco IP Phone unregisters.
Question No: 229
What is the fastest way for an engineer to test the implementation of SRST in a production environment?
Shut down the Cisco Unified Communications Manager Servers.
Shut down the switch ports connected to the Cisco Unified Communications Manager Servers.
Add a null route to the publisher Cisco Unified Communications Manager at the remote router. Remove the null route when the operation is verified.
Unplug the IP phones from their switch ports.
Verification is not needed.
Question No: 230
Refer to the exhibit.
The HQ site uses area code 650. The BR1 site uses area code 408. The long distance national code for PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9, followed by 1, and then the 10-digit number.
Both sites use MGCP gateways. AAR must use globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are localized at the egress gateway as shown in the exhibit.
Which partition should be configured in the AAR CSS applied at the phones?
The HQ AAR CSS must include a partition assigned to route pattern 91408XXXXXXX. The BR1 AAR CSS must include a partition assigned to route pattern 91650XXXXXXX.
AAR CSS must contain translation pattern 9.1[2-9]XX[2-9]XXXXXX for each site that must be globalized. Otherwise the called numbers will not be localized at the egress gateway.
