Heap dumps are snapshots of the Java heap memory that contain information about the objects and classes in the heap at the moment of the dump. Heap dumps can help you identify memory leaks, excessive memory consumption, and other memory-related issues. You can collect heap dumps using the Cisco Unified Real-Time Monitoring Tool (RTMT), which is a client application that allows you to monitor and troubleshoot Cisco Unified CCX components. To collect heap dumps, you need to enable the HeapDumpEnabled service parameter and configure theHeapDumpSchedule parameter. You can then use the RTMT to view and download the heap dumps from the Cisco Unified CCX server2.

Collect engine heap performance data via the Cisco Unified Real-Time Monitoring Tool. In addition to heap dumps, you can also collect engine heap performance data using the RTMT. This data includes metrics such as heap usage, heap size, garbage collection time, and garbage collection frequency. You can use the RTMT to monitor these metrics in real time or generate historical reports. You can also set alerts and thresholds for these metrics to receive notifications when they exceed the specified values. Collecting engine heap performance data can help you analyze the memory behavior and performance of the Cisco Unified CCX engine3.

In a Cisco Unified CCX application script, a number is read from an external database. The number must then be played out as part of a prompt. The Cisco Unified CCX Editor step that creates a new prompt that can play out the number is the Create Generated Prompt step12

The Create Generated Prompt step is a media step that allows you to create a prompt from a text or a number. The step uses the Text-to-Speech (TTS) engine or the Number-to-Speech (NTS) engine to generate a voice prompt that can be played to the caller. The step has two tabs: General and Settings. The General tab allows you to specify the input type (text or number), the input value (a variable or a literal), and the output prompt (a variable that stores the generated prompt). The Settings tab allows you to configure the TTS or NTS settings, such as the language, the voice, and the speed12

The other options are not correct:

Create Container Prompt: The Create Container Prompt step is a media step that allows you to create a prompt from a list of existing prompts. The step concatenates the prompts into a single prompt that can be played to the caller. The step has one tab: General. The General tab allows you to specify the input prompts (a list of variables or literals) and the output prompt (a variable that stores the concatenated prompt)12

Create Language Prompt: The Create Language Prompt step is a media step that allows you to create a prompt from a language-specific prompt. The step selects the prompt that matches the language of the current session and assigns it to a variable. The step has one tab: General. The General tab allows you to specify the input prompt (a variable or a literal that contains a language-specific prompt) and the output prompt (a variable that stores the selected prompt)12

Create Conditional Prompt: The Create Conditional Prompt step is a media step that allows you to create a prompt based on a condition. The step evaluates the condition and assigns the corresponding prompt to a variable. The step has two tabs: General and Settings. The General tab allows you to specify the condition (a Boolean expression) and the output prompt (a variable that stores the conditional prompt). The Settings tab allows you to specify the true prompt and the false prompt (variables or literals that contain the prompts for the true and false cases)12

The Cisco Agent Desktop (CAD) and the Cisco Supervisor Desktop (CSD) can be installed with two languages each. The languages are selected during the installation process and can be changed later by running the Postinstall.exe utility. The CAD and the CSD can have different languages installed, as long as they are supported by the Cisco Unified Contact Center Express (UCCX) system. The supported languages are listed in the Cisco Unified Contact Center Express Software and Hardware Compatibility Guide. References: Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1) - Install Cisco Agent Desktop, Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1) - Install Cisco Supervisor Desktop

 Wrap-up data is a feature that allows agents to enter a code or description that indicates the outcome or purpose of a call. This data can be used for reporting and analysis purposes. To enable wrap-up data, the administrator must configure the following settings in the Cisco Desktop Work Flow Administrator:

In the Agent Desk Settings List, select the desktop setting to which you want to apply wrap-up data.

In the Work mode on Incoming parameter, select Required with Wrapup Data or Optional with Wrapup Data. This determines whether the agent must or can enter wrap-up data after an incoming call.

In the Work mode on outgoing parameter, select Required with Wrapup Data or Optional with Wrapup Data. This determines whether the agent must or can enter wrap-up data after an outgoing call.

In the Wrapup Time parameter, enter the number of seconds that the agent has to enter wrap-up data before the agent state changes to Ready or Not Ready.

In the Work Flow Groups pane, select the work flow group to which you want to assign wrap-up data reasons.

In the Available Wrapup Data pane, select the wrap-up data reasons that you want to make available for the selected work flow group, and click the right arrow button to move them to the Work Flow Wrapup Data pane.

Click the Apply button to save the changes. References:

According to the Cisco Unified Contact Center Express Design Guide, Release 8.0(1), the maximum number of agent web chat sessions that is supported on the highest class server is 50. This means that a single agent can handle up to 50 concurrent web chat sessions on a server that meets the highest hardware specifications for Cisco Unified CCX 8.0. The highest class server for Cisco Unified CCX 8.0 is the MCS 7845, which has the following hardware configuration:

Processor: Two quad-core Intel Xeon E5440 2.83-GHz processors

Memory: 12 GB RAM

Hard disk: Four 146-GB SAS hard disks

The maximum number of agent web chat sessions depends on the hardware configuration, the deployment model, and the features enabled. For example, if Cisco Unified CCX is deployed in a high availability mode, the maximum number of agent web chat sessions is reduced to 25. If Cisco Unified CCX is deployed with Cisco Unified Presence, the maximum number of agent web chat sessions is reduced to 20. If Cisco Unified CCX is deployed with Cisco Unified Intelligence Center, the maximum number of agent web chat sessions is reduced to 10. The maximum number of agent web chat sessions also varies for different versions of Cisco Unified CCX. For example, Cisco Unified CCX 7.0 can support a maximum of 25 agent web chat sessions, while Cisco Unified CCX 9.0 can support a maximum of 60 agent web chat sessions. References: Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 3: Unified CCX Architecture and Capacity Planning, Section 3.2.3: Agent Web Chat, Page 331 Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 3: Unified CCX Architecture and Capacity Planning, Section 3.3: Unified CCX Hardware Configuration, Page 372

 The Cisco Unified Communications Sizing Tool is a web-based tool that helps system engineers to estimate the hardware server resources that are required for a Cisco Unified CCX deployment. The tool covers sizing for various components and features of the Unified CCX system, such as call control, contact center, voice messaging, conferencing and collaboration, presence, and voice gateways. The tool also provides recommendations for the optimal virtual machine (VM) configuration and placement based on the user input and the sizing rules. The tool can generate a sizing report that includes the details of the hardware and VM requirements, as well as the network bandwidth and power consumption estimates. References: Cisco Collaboration Sizing Guide - Sizing Tools Overview 1 and Using the Cisco Collaboration Sizing Tool 2

According to the Cisco Unified Contact Center Express 12.5 Data Sheet1, the maximum number of concurrent chat agents supported by Cisco Unified CCX is 70, regardless of the number of licensed seats. This means that if 70 agents log in as chat agents via an independent browser, they will consume 70 chat agent seats out of the 120 agent seats licensed for the Cisco Unified CCX deployment. The remaining 50 agent seats can be used for voice agents who log in via Cisco Agent Desktop. Therefore, the answer is A. 50. References := Cisco Unified Contact Center Express 12.5 Data Sheet, page 4.

 Skills-based routing is a method of routing calls to agents based on their skills and competencies. In Cisco Unified CCX, skills are defined as attributes that agents possess, such as language, product knowledge, or technical expertise. Agents can have multiple skills assigned to them, with different competency levels ranging from 1 (lowest) to 10 (highest). Contact Service Queues (CSQs) are logical entities that represent a group of agents who share a common set of skills required to handle a specific type of call. CSQs are associated with one or more skills, and have a minimum competency level for each skill. The agent selection criteria for skills-based routing is defined in the CSQ definition, where the administrator can choose from three options: Most Skilled, Least Skilled, or Resource Pool. These options determine how the system selects the best available agent for a call based on the skill competency levels of the agents and the CSQ. For example, if the CSQ is configured with Most Skilled, the system will select the agent with the highest skill competency level that matches the CSQ requirement. If there are multiple agents with the same skill competency level, the system will use the secondary selection criteria, such as longest available or most handled contacts, to break the tie. References: Deploying Cisco Unified Contact Center Express (UCCXD) v6.0, Cisco Unified Contact Center Express Administration Guide, Release 12.5(1)

The Database subsystem enables the Unified CCX applications to obtain information from data sources, which are databases configured to communicate with the Unified CCX system. You can connect the Unified CCX system with enterprise databases such as Microsoft SQL Server, Sybase, Oracle, or IBM DB2. The Database subsystem is available if your system has a license installed for either the Unified IP IVR or Unified CCX Premium product packages. If you are not using Unified CCX applications that require access to databases, you do not need to provision the Database subsystem. References: Cisco Unified Contact Center Express Administration Guide, Release 11.5 (1) - Provision of Additional Subsystems

 The ability to look up customers in Cisco Context Service is provided by the Customer API, which allows you to search for customers by using various parameters, such as customer ID, name, email, phone number, and so on. The Customer API returns an array of customer objects that match the search criteria, along with a pagination token that can be used to retrieve the next page of results if there are more than 100 matching customers. The customer objects contain the customer ID, the customer data fields, and the links to the related activities and requests1, 2 References: Customer API, Customer Object
