The correct answer is B. A variable in the Application Editor that is defined as a parameter means that the value for that variable can be supplied via Application Configuration in Application Administration. This allows the administrator to change the value of the variable without modifying the script. For example, a parameter variable can be used to store the CSQ name, the prompt file name, the holiday schedule, or any other value that might change over time or across applications1.

The other options are not correct because:

• A. The variable can be used to pass data to and from subflows. This is not related to the parameter property of the variable. Any variable can be used to pass data to and from subflows, as long as it is in the scope of the subflow. A subflow is a script that is invoked by another script, and it can have its own parameters that are mapped to the variables of the calling script2.
• C. The value for that variable is defined by the calling application. This is not related to the parameter property of the variable. Any variable can be defined by the calling application, as long as it is passed as an argument to the called application. An application can be called by another application using the Call Subflow step or the Trigger Application step3.
• D. The variable can be used in conditional steps. This is not related to the parameter property of the variable. Any variable can be used in conditional steps, as long as it has a valid data type and value. A conditional step is a step that evaluates an expression and executes one of the branches based on the result.
• E. The variable can be used to pass data to and from VoiceXML applications. This is not related to the parameter property of the variable. Any variable can be used to pass data to and from VoiceXML applications, as long as it is mapped to the VoiceXML session variables. A VoiceXML application is an application that uses VoiceXML documents to provide interactive voice response services.

The server that cannot be configured during the installation phase when installing Cisco Unified Contact Center Express (UCCX) on Cisco Unified Computing System (UCS) servers is the SMTP server. The SMTP server is a server that enables the email functionality of UCCX, such as sending email notifications, alerts, and reports. The SMTP server cannot be configured during the installation phase, but it can be configured after the installation by using the Cisco Unified CCX Administration web interface12

The other options can be configured during the installation phase when installing UCCX on UCS servers:

• Cisco Unified Communications Manager (CUCM) server: The CUCM server is a server that provides call control and device management for UCCX. The CUCM server can be configured during the installation phase by specifying the IP address or hostname, the username, and the password of the CUCM server. The CUCM server must be configured before the UCCX installation can proceed12
• DNS server: The DNS server is a server that resolves hostnames to IP addresses and vice versa. The DNS server can be configured during the installation phase by specifying the IP address or hostname of the primary and secondary DNS servers. The DNS server is optional, but it is recommended to use it for easier management and troubleshooting12
• NTP server: The NTP server is a server that synchronizes the time and date of UCCX with a reliable source. The NTP server can be configured during the installation phase by specifying the IP address or hostname of the primary and secondary NTP servers. The NTP server is mandatory, and the installation will fail if the UCCX server cannot reach the NTP server12

The Cisco Unified CCX Installer automatically installs the IVR System Prompts and the Unified Communications Operating System on the Cisco Unified CCX server. The IVR System Prompts are the default voice prompts that are used by the Unified CCX applications, such as the Script Editor and the Cisco Unified CCX Editor. The Unified Communications Operating System is the platform software that provides the basic functionality and security for the Unified CCX server, such as the CLI, the web interface, the database, and the license management. The Cisco Supervisor Desktop, the Cisco Unified Communications Manager, and the Workforce Management are not installed by the Cisco Unified CCX Installer. The Cisco Supervisor Desktop is a separate application that can be installed on a client PC to monitor and manage the Unified CCX agents. The Cisco Unified Communications Manager is a separate server that provides call control and signaling for the Unified CCX system. The Workforce Management is an optional component that can be purchased and installed separately to provide scheduling and forecasting capabilities for the Unified CCX agents. References := Cisco Unified Contact Center Express Install and Upgrade Guide, Release 12.5(1), Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 Course Outline

The Cisco Unified Real-Time Monitoring Tool (RTMT) is a software application that allows you to monitor and troubleshoot Cisco Unified CCX system components in real-time. The RTMT enables you to do the following tasks:

• Plot and view performance data. You can use RTMT to collect and display performance counters that measure the current system status and performance. You can view the data in graphical or tabular format, and set thresholds and alerts for the counters12
• Download log files from Cisco Unified CCX nodes. You can use RTMT to collect and view the trace and log files that are generated by the Cisco Unified CCX components. You can also configure the trace and log settings, such as the file size and rollover conditions12
• Check the number of active calls in the Cisco Unified CCX system. You can use RTMT to monitor the current call statistics, such as the number of active calls, the number of queued calls, the number of handled calls, and the average talk time. You can also view the call distribution and the agent state summary12

The RTMT does not enable you to do the following tasks:

• Monitor the replication status of historical data store. The historical data store (HDS) is a database that stores the historical reports and statistics for Cisco Unified CCX. The replication status of the HDS can be monitored by using the Data Monitor tool in the Cisco Unified CCX Serviceability web interface3
• Monitor the Cisco Unified CCX CTI port status and take corrective action. The CTI ports are the logical connections that allow Cisco Unified CCX to communicate with the Cisco Unified Communications Manager (CUCM) and control the incoming and outgoing calls. The CTI port status can be monitored by using the Cisco Unified CCX Control Center tool in the Cisco Unified CCX Serviceability web interface4
• Monitor the WAN link status. The WAN link status is the network connectivity between the Cisco Unified CCX nodes and other network devices. The WAN link status can be monitored by using the Cisco Unified Serviceability web interface or the Cisco Unified OS Administration web interface5
