This statement is false because a subflow cannot access all variables in the calling script, unless they are passed as input parameters or global variables. A subflow has its own local variables that are not visible to the calling script. A subflow can only access the variables that are mapped to its input parameters or declared as global variables1.

The other statements are true because:

B. When the Call Subflow step executes, you can transfer values of variables from the calling flow to the subflow. This statement is true because you can use the Input Mappingstab of the Call Subflow step to map the variables from the calling flow to the input parameters of the subflow. This allows you to pass data to the subflow and initialize its variables2.

C. After the Call Subflow step executes, you can transfer values of variables from the subflow to the calling flow. This statement is true because you can use the Output Mappings tab of the Call Subflow step to map the variables from the subflow to the variables of the calling flow. This allows you to return data from the subflow and update the variables of the calling flow3.

D. The same subflow can be invoked from different scripts. This statement is true because a subflow is an independent script that can be reused in other scripts. You can call the same subflow from different scripts using the Call Subflow step and specify the subflow name and location4.

he gateway is the option that can perform Call Progress Analysis (CPA) in outbound IVR. CPA is a DSP algorithm that analyzes the RTP voice stream to look for special information tones (SIT), fax or modem tones, human speech, and answering machine tones. CPA also passes the voice information to Cisco IOS or CUBE. CPA is initiated on receiving a new SIP INVITE with x-cisco-cpa content. The gateway detects non-live contact with its CPA capabilities and sends the status of the non-live contact to the dialer. The dialer then decides whether to redirect the call to UCCX or terminate the call based on the CPA event. References: Cisco Unified Border Element Configuration Guide - Cisco IOS XE 17.6 Onwards - Call Progress Analysis, IVR-Based Outbound Dialer Troubleshooting

To develop a custom Cisco Unified Intelligence Center report for a Cisco Unified CCX deployment, you need the Cisco Unified Intelligence Center Premium package. This package allows you to create custom reports using the Report Definition tool, which provides access to all the data sources, fields, filters, drilldowns, and formatting options. The Cisco Unified Intelligence Center Standard package only allows you to run predefined reports and make limited modifications, such as changing the layout, adding filters, and scheduling. The Cisco Unified CCX Premium and Enhanced packages do not affect the Cisco Unified Intelligence Center reporting capabilities, as they are related to the Unified CCX features and licenses. References: Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 - Module 3: Operate a Cisco Unified Contact Center Express System - Lesson 1: Cisco Unified Intelligence Center Reports - Topic: Cisco Unified Intelligence Center Overview

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 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.

To send an HTTP message, you should use the following Cisco Unified CCX steps:

Send HTTP Response: This step allows the script to send an HTTP response to the client that initiated the HTTP request. The step specifies the HTTP status code, the content type, and the body of the response. The step can also set or delete cookies in the response. For more information on how to use the Send HTTP Response step, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Steps, Section: Send HTTP Response Step.

Create URL Document: This step allows the script to create a URL document that contains the URL of a web page or application. The step specifies the URL, the method (GET or POST), and the parameters to be sent with the request. The step can also set or delete cookies in the request. The URL document can be used as an input for other steps, such as Write Document or Place Call. For more information on how to use the Create URL Document step, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Steps, Section: Create URL Document Step.

The following steps cannot be used to send an HTTP message:

Write Document: This step allows the script to write a document to a file or a stream. The step specifies the document, the destination, and the encoding. The document can be any type of document, such as XML, plain text, or URL. The destination can be a local file, a remote file, or a media stream. The step can be used to write a URL document to a file or a stream, but it cannot send an HTTP message by itself. For more information on how to use the Write Document step, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Steps, Section: Write Document Step.

Place Call: This step allows the script to place a call to a destination. The step specifies the calling address, the called address, the media termination, and the timeout. The calling address and the called address can be phone numbers, SIP URIs, or URL documents. The media termination can be a contact, a prompt, or a document. The step can be used to place a call to a URL document, but it cannot send an HTTP message by itself. For more information on how to use the Place Call step, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Steps, Section: Place Call Step.

Cache Document: This step allows the script to cache a document in the memory of the Unified CCX server. The step specifies the document and the cache key. The document can be any type of document, such as XML, plain text, or URL. The cache key is a unique identifier for the document in the cache. The step can be used to cache a URL document, but it cannot send an HTTP message by itself. For more information on how to use the Cache Document step, see the Cisco Unified Contact Center Express Editor Step Reference, Release 12.5 (1), Chapter: Steps, Section: Cache Document Step. References:

A contact service queue (CSQ) is a logical grouping of agents that share similar skills. In Cisco Unified Contact Center Express, skills are assigned to CSQs, not to individual agents. Agents are associated with resource groups, which are then mapped to CSQs based on the skills required. This allows the system to route calls to the most appropriate CSQ, and then to the most qualified agent within that CSQ. References: UCCXD - Deploying Cisco Unified Contact Center Express v6.0, Cisco Unified Contact Center Express Administration Guide, Release 10.0 (1)

The security password is used as the secret key during the second node installation of Cisco Unified Contact Center Express (UCCX). This password is entered during the first node installation and must be the same for all nodes in the cluster. The security password is used to encrypt sensitive data in the database and to authenticate communication between nodes. If the security password is not the same for all nodes, the installation will fail and the cluster will not function properly. References: Cisco Unified Contact Center Express Install and Upgrade Guide, Release 12.5 (1) - Unified CCX Installation, Free Cisco Deploying Unified Contact Center Express (UCCXD) v6.0 Certification Sample Questions and Answers

According to the Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Cisco Unified CCX 8.0 can support a maximum of 400 agents when deployed with Cisco Unified Communications Manager. This is the highest capacity option for Cisco Unified CCX 8.0, which requires a dedicated server for the Cisco Unified CCX Engine and a dedicated server for the Cisco Unified CCX Database. The maximum number of agents 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 agents is reduced to 300. If Cisco Unified CCX is deployed with Cisco Unified Presence, the maximum number of agents is reduced to 250. If Cisco Unified CCX is deployed with Cisco Unified Intelligence Center, the maximum number of agents is reduced to 150. The maximum number of agents also varies for different versions of Cisco Unified CCX. For example, Cisco Unified CCX 7.0 can support a maximum of 300 agents, while Cisco Unified CCX 9.0 can support a maximum of 500 agents. References: Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 2: Unified CCX Product Overview, Section 2.1: Unified CCX Product Packages, Page 151 Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 3: Unified CCX Architecture and Capacity Planning, Section 3.1: Unified CCX Deployment Models, Page 252 Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 3: Unified CCX Architecture and Capacity Planning, Section 3.2: Unified CCX Capacity Planning, Page 293

 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:

According to the Cisco Unified Contact Center Express Design Guide, Release 8.0(1), the maximum number of CTI ports that can be supported by a Cisco Unified Contact Center Express 8.0 Standard deployment is 300. This is the same as the maximum number of IVR ports that can be supported by the Standard deployment. The CTI ports are used to route calls to agents or to play prompts and collect caller input. The number of CTI ports depends on the number of concurrent calls that the system needs to handle and the call flow design. The Standard deployment supports up to 150 agents and 300 IVR ports or CTI ports. References := Cisco Unified Contact Center Express Design Guide, Release 8.0(1), page 2-7.

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.

 The option that can be configured while installing Cisco Unified CCX on Cisco UCS servers is the NTP server. The NTP server is used to synchronize the time between the Unified CCX nodes and other components such as CUCM, LDAP, and SMTP servers. The NTP server must be configured on the first node before installing the second node, otherwise the installation will fail. The NTP server can be configured in the basic configuration information that is required during installation. The DNS server, the SMTP server, and the CUCM server are not configured during the installation, but they can be configured later in the Unified CCX Administration web interface. References := Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 > Module 2: Implementing Cisco Unified Contact Center Express > Lesson 2: Installing Cisco Unified Contact Center Express > Topic 2.2: Installing Unified CCX1

 The Agent email feature is available only in the Cisco Unified Contact Center Express Premium package. The Agent email feature is a basic email queuing and response system that allows agents to handle customer emails from the Cisco Agent Desktop. The feature supports email routing, email prioritization, email response templates, email attachments, email history, and email reporting12

The other options are not correct:

Premium and Enhanced: The Agent email feature is not available in the Enhanced package. The Enhanced package supports only voice and chat interactions12

Premium, Enhanced, and Standard: The Agent email feature is not available in the Enhanced and Standard packages. The Standard package supports only voice interactions12

Premium and Standard: The Agent email feature is not available in the Standard package. The Standard package supports only voice interactions12

CSQs are associated to the team definition to designate which CSQ information to display on the supervisor desktop. The supervisor desktop allows the supervisor to monitor and manage the agents and the CSQs that are assigned to the team. The supervisor can view the real-time statistics, historical reports, and chat transcripts of the CSQs that are associated to the team. The supervisor can also change the skill competency level of the agents for the CSQs that are associated to the team1, page 2-3, 2, page 2-5, 3, page 2-6. References: Cisco Unified Contact Center Express Features Guide, Release 12.5 (1), Cisco Finesse Supervisor Desktop User Guide for Cisco Unified Contact Center Express, Release 12.5 (1), Cisco Unified Contact Center Express Administration and Operations Guide, Release 12.0 (1)

The database subsystem is used to communicate with external database servers and execute SQL queries from Unified CCX applications. The database subsystem is available only if the system has a license installed for either the Unified IP IVR or Unified CCX Premium product packages. If the database subsystem is not configured, it will show as out of service on the Control Center page of AppAdmin. This means that the database subsystem is not operational and cannot process any requests from the applications. To configure the database subsystem, you need to add database resources and specify the connection parameters for each database server that you want to access from your applications. You also need to enable the database subsystem from the Control Center page after adding the database resources. References: Cisco Unified Contact Center Express Administration Guide, Release 11.5 (1) - Database Subsystem Configuration

The Cisco Unified CCX Sizing Tool is a web-based tool that allows partners to validate the parameters of a target Cisco Unified CCX configuration, such as the number of inbound agents, the number of inbound and outbound IVR ports, the number of historical reporting users, and so on. The tool also recommends servers based on the validated configuration, which is a prerequisite for the Cisco assessment-to-quality bid assurance process. The tool can be accessed from the Cisco Unified CCX Partner Central1. The tool helps partners to design a Cisco Unified CCX system that meets the customer requirements and avoids oversizing or undersizing the system. References := Cisco Unified CCX Partner Central

To troubleshoot a Cisco Unified Contact Center Express engine “Java out of memory” crash, you should perform the following steps:

Collect the thread dump for Cisco Unified CCX Engine: A thread dump is a snapshot of the state of all the threads that are part of the process. The thread dump will show what each thread is doing, what resources they are holding, and what other threads they are waiting for. This can help identify any deadlocks, loops, or hung threads that could cause memory leaks or high memory usage. To collect the thread dump for Cisco Unified CCX Engine, use the Cisco Unified Real-Time Monitoring Tool (RTMT) and navigate to Trace and Log Central > Collect Files > Select Cisco Unified CCX Engine > Check Thread Dump > Finish. For more information on how to collect the thread dump, see the Cisco Unified Contact Center Express Serviceability Administration Guide, Release 12.5 (1), Chapter: Unified CCX Serviceability, Section: Trace and Log Central, Subsection: Collecting Thread Dumps.

Collect engine heap performance data via the Cisco Unified Real-Time Monitoring Tool: The engine heap is the area of memory where the Cisco Unified CCX Engine stores the objects it creates and uses. The engine heap performance data will show how much heap memory is allocated, used, and freed by the engine, as well as the number and frequency of garbage collections. This can help identify any memory leaks, memory fragmentation, or insufficient heap size issues that could cause memory exhaustion or degradation. To collect the engine heap performance data, use the RTMT and navigate to System > Performance > Open Performance Monitoring > Select Cisco Unified CCX Engine > Select Heap Usage and GC Counters. For more information on how to collect the engine heap performance data, see the Cisco Unified Contact Center Express Reporting Guide, Release 11.6(2), Chapter: Unified CCX Engine Heap Usage Monitoring.

Talk to the customer about the deployment and usage pattern: The deployment and usage pattern of the customer will provide information about the configuration, load, and behavior of the Cisco Unified CCX system. This can help identify any factors that could contribute to the memory issues, such as the number of applications, scripts, sessions, agents, teams, skills, CSQs, triggers, historical reports, etc. The deployment and usage pattern can also help determine the best practices and recommendations for optimizing the system performance and avoiding memory problems. To talk to the customer about the deployment and usage pattern, use the Unified CCX 12.5 Sizing Tool and the Cisco Unified Contact Center Express Solution Reference Network Design, Release 12.5 (1) as references.

The following steps are not required or not possible to troubleshoot a Cisco Unified Contact Center Express engine “Java out of memory” crash:

Check to see if the customer has installed any third party applications: This step is not required, because the Cisco Unified CCX platform does not support the installation of any third party applications. The platform is a closed system that only allows the installation of Cisco-approved software and patches. Any attempt to install third party applications on the platform will cause the system to fail the integrity check and prevent the system from functioning properly. For more information on the platform compatibility and restrictions, see the Cisco Unified Contact Center Express Software and Hardware Compatibility Guide, Release 12.5(1), Chapter: Platform Considerations, Section: Platform Compatibility.

Collect heap dumps via the Cisco Unified Real-Time Monitoring Tool: This step is not possible, because the RTMT does not provide the option to collect heap dumps for the Cisco Unified CCX Engine. A heap dump is a snapshot of the memory allocation of the process, which shows the objects, classes, and references in the heap. A heap dump can be useful for analyzing the memory usage and finding memory leaks, but it requires a tool that can capture and read the heap dump file. The RTMT can only collect and view trace files, logs, and performance counters for the Cisco Unified CCX Engine. To collect heap dumps for the Cisco Unified CCX Engine, a different tool or method is needed, such as using the jmap command or the [Java VisualVM] tool.

Check the Cisco Unified CCX Serviceability Control Center: This step is not helpful, because the Cisco Unified CCX Serviceability Control Center only shows the status and allows the control of the Cisco Unified CCX services and components. It does not provide any information or tools for troubleshooting memory issues or crashes. The Control Center can be used to start, stop, or restart the Cisco Unified CCX Engine service, but this will not resolve the root cause of the memory problem. To troubleshoot memory issues or crashes, other tools or methods are needed, such as using the RTMT, the CLI, or the web interface. For more information on the Cisco Unified CCX Serviceability Control Center, see the Cisco Unified Contact Center Express Serviceability Administration Guide, Release 12.5 (1), Chapter: Unified CCX Serviceability, Section: Control Center - Network Services. References:

A Contact Service Queue (CSQ) is a logical grouping of agents that share similar skills and can handle similar types of contacts. A CSQ is defined by three main fields: the Resource Selection Criteria, the Service Level, and the Overflow CSQ. The Resource Selection Criteria determines how the system selects the most appropriate agent for each contact based on the agent’s competency level and availability. The Service Level defines the percentage of contacts that should be answered within a specified time threshold. The Overflow CSQ specifies another CSQ to which the contacts are redirected when the current CSQ reaches its maximum capacity or when the contacts wait in the queue for too long. These three fields are essential for defining a CSQ in Cisco Unified Contact Center Express Enhanced. The other fields, such as Agent Name, Automatic Work, and CCX Application, are not used in defining a CSQ, but rather in configuring other aspects of the system, such as agent settings, workflow groups, and scripts. References: Cisco Unified Contact Center Express Design Guide, Release 11.0 (1), [Cisco Unified Contact Center Express Administration Guide, Release 11.0 (1)]
