The default eMail address in the eMail Subsystem Configuration page is used as the From address in the Send eMail step if no address is specified. This is useful when you want to send emails from a generic or default address without having to specify it in every Send eMail step. The default eMail address can be configured in the Unified CCX Administration web interface, under Subsystems > eMail > eMail Subsystem Configuration. You can also specify the default eMail address in the script editor, using the Set Default eMail Address step. References := Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 > Module 3: Implementing Cisco Unified Contact Center Express Scripting > Lesson 3: Implementing Basic Scripting Techniques > Topic 3.3: Sending an E-mail Message1

 The application username is not an input that is required when you install Cisco Unified CCX. The application username is the username that you use to log in to the Cisco Unified CCX Administration web interface after the installation is complete. You can configure the application username during the initial system setup, which is a separate step from the installation. The other inputs, such as the platform administrator username, the IP address, the default language, and the time zone, are required during the installation process. You need to enter these inputs to configure the basic system parameters and network settings for the Unified CCX server. References := Cisco Unified Contact Center Express Install and Upgrade Guide, Release 12.5(1) SU2, Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 Course Outline

 The Cisco Unified CCX steps that would make an HTTP request are Cache Document and Send Http Response. The Cache Document step sends an HTTP GET request to a specified URL and stores the response in a Document variable. The Send Http Response step sends an HTTP response to the client that initiated the HTTP request. The response can include a status code, headers, cookies, and a body1, pages 2-81 and 2-82. The following steps do not make an HTTP request:

• Create URL Document: This step creates a URL Document variable from a string or a URL. The step does not send or receive any data over the network1, page 2-78.
• Write Document: This step writes a Document variable to a file on the local disk or a network share. The step does not use the HTTP protocol1, page 2-79. References: Cisco Unified Contact Center Express Editor Step Reference Guide, Release 11.6(2)

In a Cisco Unified Contact Center Express deployment with Cisco Unified Communications Manager Express, the embedded browser feature is disabled on the Cisco Agent Desktop. The embedded browser feature allows the agent to view web pages or applications within the Cisco Agent Desktop window, such as customer information, scripts, or web chat. However, this feature requires the Cisco Unified Communications Manager to provide CTI data to the Cisco Agent Desktop, which is not supported by the Cisco Unified Communications Manager Express. Therefore, the embedded browser feature is not available when using Cisco Unified Communications Manager Express as the call control system. References := Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1) SU3, Chapter 2: Preinstallation Tasks for Cisco Unified CCX, Cisco Unified Communications Manager Express, page 2-11.

Historical reports can be generated using the Historical Reporting Client (HRC) and the Cisco Unified Intelligence Center (CUIC). The HRC is a standalone application that allows supervisors and administrators to view and print reports on historical data from the Unified CCX server. The CUIC is a web-based reporting application that provides real-time and historical reports for Unified CCX. Both tools allow users to create, schedule, and export reports on various aspects of the Unified CCX system, such as agent performance, call statistics, and system health. References:

• Cisco Unified Contact Center Express Reporting Guide, Release 11.6(2), Chapter: Historical Reports

The On Exception Goto step can be used to trap runtime script errors and recover gracefully. This step allows the script to handle exceptions that may occur during the execution of the script, such as ContactInactiveException, DatabaseException, or DocumentException. The step specifies the type of exception to catch and the label to jump to when the exception occurs. The label can be any valid label in the script that marks the beginning of a recovery or cleanup section. For example, the script can use the On Exception Goto step to catch a ContactInactiveException and jump to a label that logs the call details and ends the script. This way, the script can avoid looping or crashing when the contact is dropped or disconnected. For more information on how to use the On Exception Goto step, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Steps, Section: On Exception Goto Step. References:

• Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1)

The maximum number of concurrent agent web chat sessions that are supported on the highest class server is 50. This means that each agent can handle up to 50 simultaneous web chat contacts on a server that meets the highest specifications for Cisco Unified Contact Center Express (UCCX). The highest class server for UCCX is the Cisco Unified Computing System (UCS) C240 M5, which supports up to 400 agents and 400 IVR ports1.

The other options are not correct because:

• A. 75 is not the maximum number of concurrent agent web chat sessions that are supported on the highest class server. 75 is the maximum number of concurrent agent web chat sessions that are supported on the second highest class server, which is the Cisco UCS C220 M5. This server supports up to 300 agents and 300 IVR ports1.
• B. 25 is not the maximum number of concurrent agent web chat sessions that are supported on the highest class server. 25 is the maximum number of concurrent agent web chat sessions that are supported on the third highest class server, which is the Cisco UCS C220 M4. This server supports up to 200 agents and 200 IVR ports1.
• D. 120 is not the maximum number of concurrent agent web chat sessions that are supported on the highest class server. 120 is the maximum number of concurrent agent web chat sessions that are supported on the entire UCCX system, regardless of the server class. This means that the total number of web chat contacts across all agents cannot exceed 1202.

To convert a high availability over LAN deployment to high availability over WAN, you need to reinstall the second Cisco Unified CCX node and add it to the cluster over WAN. This is because the high availability over WAN deployment requires a different network configuration and a different license than the high availability over LAN deployment12

The high availability over WAN deployment allows you to have two Cisco Unified CCX nodes in different geographical locations, connected by a WAN link with a minimum bandwidth of 1.544 Mbps and a maximum round-trip delay of 80 ms. The high availability over WAN deployment provides disaster recovery and business continuity in case of a site failure12

The high availability over WAN deployment requires a “WAN Standby” license, which is different from the “Warm Standby” license used for the high availability over LAN deployment. The “WAN Standby” license enables the second Cisco Unified CCX node to operate in a partial service mode, which means that it can accept and process calls, but it cannot access the historical data or the configuration data from the primary node. The “Warm Standby” license enables the second Cisco Unified CCX node to operate in a full service mode, which means that it can access all the data and functions of the primary node12

To convert a high availability over LAN deployment to high availability over WAN, you need to follow these steps:

• Backup the configuration and the historical data from the primary Cisco Unified CCX node2
• Uninstall the second Cisco Unified CCX node from the cluster2
• Reinstall the second Cisco Unified CCX node with the same software version and patch level as the primary node, but with a different IP address and hostname2
• Apply the “WAN Standby” license to the second Cisco Unified CCX node2
• Add the second Cisco Unified CCX node to the cluster over WAN by using the Cisco Unified CCX Administration web interface on the primary node2
• Restore the configuration and the historical data to the second Cisco Unified CCX node2
• Verify the high availability status and the data synchronization between the two nodes2

No information is readable to Cisco Collaboration Software in the cloud. Cisco Collaboration Software uses end-to-end encryption to protect the data and privacy of its users. End-to-end encryption means that the data is encrypted at the source device and decrypted only at the destination device. No one, including Cisco, can access or read the data while it is in transit or at rest in the cloud. Cisco Collaboration Software uses strong encryption algorithms and keys that are generated and managed by the users themselves12

The correct answer is C. Only agent phones that are used with the Cisco Finesse agent desktop must be associated to the RmCm application user account. The RmCm application user account is a special user account that is created by Cisco Unified Contact Center Express (UCCX) during the initial setup and is used to control and monitor the agent phones through the Computer Telephony Integration (CTI) interface. The RmCm application user account must have the Standard CTI Enabled and Standard CTI Allow Control of Phones supporting Connected Xfer and conf user roles, and must have the agent phones associated as controlled devices. This allows the UCCX to perform actions such as logging in and out agents, changing agent states, making and receiving calls, transferring and conferencing calls, and sending and receiving enterprise data1.

The other options are not correct because:

• A. All phones must be associated to the RmCm application user account. This is false because not all phones need to be controlled and monitored by UCCX. Only the phones that are used by the agents who log in to the Cisco Finesse agent desktop need to be associated to the RmCm application user account. Other phones, such as supervisor phones, IVR phones, or non-UCCX phones, do not need to be associated to the RmCm application user account2.
• B. None, because that user account is not used for phone association. This is false because the RmCm application user account is used for phone association. The RmCm applicationuser account is the user account that UCCX uses to communicate with the Cisco Unified Communications Manager (CUCM) and control the agent phones. Without phone association, the RmCm application user account cannot perform the CTI functions that are required for the UCCX features1.
• D. Only Cisco Finesse IPPA phones must be associated to the RmCm application user account. This is false because Cisco Finesse IPPA phones are not supported by UCCX. Cisco Finesse IPPA is a feature that allows agents to use the Cisco IP Phone Agent (IPPA) service to log in to the Cisco Finesse server and access the Cisco Finesse agent desktop features. However, this feature is only available for Cisco Unified Contact Center Enterprise (UCCE), not for UCCX. UCCX agents can only use the Cisco Finesse agent desktop web interface or the Cisco Agent Desktop (CAD) application to log in and access the UCCX features3.

You can also view the status of each service and the server on which it is running. The Control Center is accessible from the Navigation drop-down list on the Cisco Unified CCX Serviceability page. You can select either Network Services or Feature Services to manage the corresponding services. References: Cisco Unified Contact Center Express Operations Guide, Release 11.5 (1) - Cisco Unified CCX Serviceability1, Serviceability Tools1

 To support presence integration, an administrator must perform the following tasks on Cisco Desktop Administrator:

• Assign a contact list to a workflow group: A contact list is a collection of subject matter experts (SMEs) who can assist agents with customer inquiries. A workflow group is a logical grouping ofagents who share the same configuration settings, such as workflows, reason codes, phone books, and contact lists. By assigning a contact list to a workflow group, the administrator enables the agents in that group to see the presence status of the SMEs in the contact list and initiate chat sessions with them.
• Assign an SME to a contact list: An SME is a person who has expertise in a specific domain or topic and can provide assistance to agents or customers. An SME can be an internal or external user who is registered with Cisco Unified Presence. By assigning an SME to a contact list, the administrator adds the SME’s contact information, such as name, phone number, and email address, to the contact list. The administrator can also specify the SME’s availability schedule and skills. References:

The Cisco Unified Communications Sizing Tool is a web-based application that helps customers and partners accurately size Cisco Unified Communications hardware, software, and services. The tool can be used to size Cisco Unified CCX by selecting the product family, the deployment model, the reference design, the call volume, the agent count, the features, and the hardware specifications. The tool then generates a report that shows the recommended hardware configuration, the software licenses, the power consumption, the rack space, and the bill of materials for the Cisco Unified CCX solution1, 2 References: Solution Design Guide for Cisco Unified Contact Center Express, Release 11.5 (1), Cisco Sizing tools - Cisco Community

Reactive debugging is a facility provided by the Cisco Unified CCX Editor that allows you to debug a Cisco Unified CCX script live with a real voice call. Reactive debugging enables you to step through the script execution and view the variable values and the call flow in real time. You can also set breakpoints and watchpoints to pause the script execution and inspect the variables. Reactive debugging is useful for troubleshooting and testing the script logic and functionality12

The three tasks that an agent can perform using email are:

• Save the response as a draft. An agent can save an email response as a draft and resume working on it later. The draft email is stored in the agent’s personal folderand can be accessed from the email control bar. The agent can edit, delete, or send the draft email at any time1.
• Transfer the email to another CSQ. An agent can transfer an email to another Contact Service Queue (CSQ) if the email requires a different skill set or expertise. The agent can select the destination CSQ from a list of available CSQs and add an optional note for the next agent. The email is then removed from the agent’s work area and placed in the selected CSQ2.
• Transfer the email to another agent. An agent can transfer an email to another agent if the email requires a specific agent to handle it. The agent can select the destination agent from a list of available agents and add an optional note for the next agent. The email is then removed from the agent’s work area and placed in the selected agent’s personal folder3.

The other options are not correct because:

• Send the response to the supervisor for review. An agent cannot send an email response to the supervisor for review before sending it to the customer. The agent can only send the email response directly to the customer or save it as a draft4.
• Mark the email as urgent. An agent cannot mark an email as urgent. The urgency of an email is determined by the email server based on the email header. The agent can only view the urgency of an email, but cannot change it5.
• Mark the email as junk. An agent cannot mark an email as junk. The junk email filtering is done by the email server based on the email content and sender. The agent can only view the junk status of an email, but cannot change it6.

 In a high availability over WAN deployment, the ASR or TTS servers cannot be across the WAN from the active Cisco Unified CCX site. This is because the ASR or TTS servers require a low latency connection to the Unified CCX engine, and the WAN link may introduce delays or packet loss that can affect the quality and performance of the speech recognition or text-to-speech services. Therefore, the ASR or TTS servers must be co-located with the active Unified CCX site, and they must fail over to the standby site if the active site goes down. References: Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 - Module 1: Design a Cisco Unified Contact Center Express System Deployment - Lesson 4: High Availability and Network Design - Topic: Unified CCX High Availability over WAN1

To deploy a Cisco Unified CCX application, the following tasks are required:

• Create a trigger: A trigger is a phone number or a URI that is associated with an application and invokes a script when it is dialed or requested. A trigger defines the type of communication (voice or HTTP), the maximum number of sessions, and the script to be executed. To create a trigger, use the Cisco Unified CCX Administration web interface and navigate to Applications > Trigger Management. For more information on how to create a trigger, see the Cisco Unified Contact Center Express Administration and Operations Guide, Release 12.5 (1), Chapter: Unified CCX Application Configuration, Section: Trigger Management.
• Upload script to repository: A script is a set of instructions that defines the call flow and logic of an application. A script is created using the Cisco Unified CCX Editor, which is a graphical tool that allows users to drag and drop steps, variables, and expressions. To upload a script to the repository, use the Cisco Unified CCX Editor and select File > Save Script As. For more information on how to upload a script, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Saving and Uploading Scripts, Section: Saving and Uploading Scripts.
• Specify the maximum number of sessions: The maximum number of sessions defines how many concurrent calls or requests an application can handle. The maximum number of sessions is configured at the trigger level and depends on the license type and the available system resources. To specify the maximum number of sessions, use the Cisco Unified CCX Administration web interface and navigate to Applications > Trigger Management. For more information on how to specify the maximum number of sessions, see the Cisco Unified Contact Center Express Administration and Operations Guide, Release 12.5 (1), Chapter: Unified CCX Application Configuration, Section: Trigger Management.

The following tasks are not required to deploy a Cisco Unified CCX application:

• Restart the Cisco Unified CCX Engine: The Cisco Unified CCX Engine is a service that runs on the Unified CCX server and executes the scripts associated with the applications. The Cisco Unified CCX Engine does not need to be restarted after deploying an application, unless there is a change in the system configuration or a problem with the service. To restart the Cisco Unified CCX Engine, use the Cisco Unified CCX Serviceability web interface and navigate to Tools > Control Center - Network Services. For more information on how to restart the Cisco Unified CCX Engine, see the Cisco Unified Contact Center Express Serviceability Administration Guide, Release 12.5 (1), Chapter: Unified CCX Serviceability, Section: Control Center - Network Services.
• Configure default session timeout: The default session timeout defines how long an idle session can remain active before it is terminated by the system. The default session timeout is configured at the system level and applies to all applications. The default session timeout does not need to be configured for each application, unless there is a specific requirement to override the system value. To configure the default session timeout, use the Cisco Unified CCX Administration web interface and navigate to System > System Parameters. For more information on how to configure the default session timeout, see the Cisco Unified Contact Center Express Administration and Operations Guide, Release 12.5 (1), Chapter: Unified CCX System Configuration, Section: System Parameters. References:

The three components that are installed from the Cisco CRS Installer media are the Cisco CRS Engine, the Cisco Recording, and the MS SQL Server. The Cisco CRS Engine is the core component of the Unified CCX system that provides the call processing, scripting, and application integration functions. The Cisco Recording is the component that enables the recording and playback of agent calls for quality monitoring and training purposes. The MS SQL Server is the component that provides the database services for the Unified CCX system, such as storing configuration data, historical data, and agent data. The other components listed are not installed from the Cisco CRS Installer media. The iPlanet Web Server is not used by the Unified CCX system, as it uses the Apache Tomcat Web Server instead. The Cisco IP Telephony Windows 2000 Server OS is not a component of the Unified CCX system, as it uses the Linux-based Cisco Unified Communications Operating System. The Cisco Unified CallManager is not a component of the Unified CCX system, but a separate product that provides the call control and signalingfunctions for the IP telephony network. References := Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 > Module 2: Implementing Cisco Unified Contact Center Express > Lesson 1: Installing Cisco Unified Contact Center Express > Topic 1.1: Cisco Unified CCX Installation Overview1

 Cisco Unified Contact Center Express does not support an embedded Internet browser within the Cisco Agent Desktop. The Cisco Agent Desktop is a legacy desktop application that provides call control and agent state management for Unified CCX agents. The Cisco Agent Desktop does not have an embedded Internet browser, but it can launch an external browser to display web pages or applications. However, the Cisco Agent Desktop is deprecated and replaced by the Cisco Finesse desktop, which is a web-based agent and supervisor desktop that supports an embedded Internet browser. The CiscoFinesse desktop is available for all Unified CCX platform sets, including Standard, Enhanced, and Premium. For more information on the differences between the Cisco Agent Desktop and the Cisco Finesse desktop, see the Cisco Unified Contact Center Express Solution Reference Network Design, Release 12.5 (1), Chapter: Cisco Unified CCX Desktop Options, Section: Cisco Agent Desktop and Cisco Finesse Desktop Comparison. References:

Cisco Finesse supports the use of custom call variable layouts to define how call variables appear on the Finesse agent desktop. The agent desktop determines which layout to use based on the value of a keyword variable that is named user.layout. This variable is passed to the agent desktop via the Set Enterprise Call Info step in the CCX script. The value of the user.layout variable must match the name of the custom call variable layout that is configured in the Finesse Administration page. If no user.layout variable exists, or if the value does not match any custom layout, the default layout will be used12
