500-052 Exam Dumps : Deploying Cisco Unified Contact Center Express (UCCXD)

The Cisco Unified Communications Sizing Tool is a web-based tool that helps system engineers to size Cisco Unified Communications solutions, including Cisco Unified CCX. The tool can validate various parameters and requirements for a Cisco Unified CCX deployment configuration, such as the number of agents, supervisors, IVR ports, outbound ports, chat sessions, email sessions, and reporting users. However, the tool cannot validate the following options:

• The number of silent-monitoring and remote-monitoring sessions. Silent monitoring and remote monitoring are features that allow supervisors to listen to the agent’s calls without being heard by the agent or the caller. The tool does not support sizing for these features,as they depend on the network bandwidth and the codec used for the calls. The tool only provides a formula to estimate the bandwidth requirement for silent monitoring and remote monitoring, based on the number of sessions, the codec, and the packet size. The formula is: Bandwidth (kbps) = Number of sessions x Codec bit rate x (1 + Network overhead). For example, if there are 10 silent-monitoring sessions using G.711 codec with a bit rate of 64 kbps and a network overhead of 20%, the bandwidth requirement is: Bandwidth (kbps) = 10 x 64 x (1 + 0.2) = 768 kbps1.
• The number of historical reporting sessions. Historical reporting is a feature that allows users to generate reports on the historical data of the Cisco Unified CCX system, such as agent performance, call statistics, and queue summary. The tool does not support sizing for this feature, as it depends on the number of reporting users, the frequency and complexity of the reports, and the database size. The tool only provides some guidelines and best practices for historical reporting, such as limiting the number of concurrent reporting users to 10, scheduling the reports during off-peak hours, and purging the historical data regularly2.
• The number of ASR and TTS ports. ASR (Automatic Speech Recognition) and TTS (Text-To-Speech) are features that enable voice interaction between the callers and the IVR system, using speech recognition and synthesis technologies. The tool does not support sizing for these features, as they are provided by third-party vendors, such as Nuance or LumenVox. The tool only provides some recommendations and considerations for ASR and TTS integration, such as using MRCPv2 protocol, allocating enough CPU and memory resources, and configuring the network QoS policies3.

 The correct answer is B. The default script field when adding an application specifies the script that will be executed if there are any problems running the configured script for the application. For example, if the configured script is missing, corrupted, or containserrors, the default script will be executed instead. The default script field is mandatory and must point to a valid script file1.

The other options are not correct because:

• A. When a caller does not enter a choice in a Menu step, it will execute the default script. This is false because the Menu step has its own Timeout branch that determines what to do when the caller does not enter a choice within the specified timeout period. The default script field has no effect on the Menu step2.
• C. When the caller enters a digit in the Menu step that is not defined, the default script will be executed. This is false because the Menu step has its own Unsuccessful branch that determines what to do when the caller enters a digit that is not defined as a valid option. The default script field has no effect on the Menu step2.
• D. When the caller enters a digit that is not checked in the filter of the Get Digit String step, the default script will be executed. This is false because the Get Digit String step has its own Invalid Entry branch that determines what to do when the caller enters a digit that is not checked in the filter. The default script field has no effect on the Get Digit String step3.

 The Cisco Unified CCX license MAC is generated based on the hostname, IP address, and gateway address of the Unified CCX server. These are some of the system parameters that affect the license MAC, which is different from the physical MAC address of the system. Changing any of these parameters can invalidate the current license files. The Cisco Unified CCX version and the physical MAC are not used to generate the license MAC. References := Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1), Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 Course Outline
