Free Practice Questions for Cisco 500-052 Exam

A supervisor who does not have administrative privilege can perform the following Cisco Unified Contact Center Express Application Administration tasks:

Remove a skill from a CSQ: A skill is a competency that an agent possesses, such as language, product knowledge, or technical expertise. A Contact Service Queue (CSQ) is a logical grouping of agents based on their skills. A supervisor can remove a skill from a CSQ by using the Cisco Unified CCX Administration web interface and navigating to Subsystems > RmCm > Contact Service Queues. For more information on how to remove a skill from a CSQ, see the Cisco Unified Contact Center Express Administration Guide, Release 10.0 (1), Chapter: Unified CCX Application Configuration, Section: Contact Service Queues.

Enable automatic work on a CSQ: Automatic work is a feature that allows agents to automatically enter the work state after they finish a call or chat. This prevents the agents from receiving new contacts until they are ready. A supervisor can enable automatic work on a CSQ by using the Cisco Unified CCX Administration web interface and navigating to Subsystems > RmCm > Contact Service Queues. For more information on how to enable automatic work on a CSQ, see the Cisco Unified Contact Center Express Administration Guide, Release 10.0 (1), Chapter: Unified CCX Application Configuration, Section: Contact Service Queues.

Modify the skill competence level of an agent: The skill competence level is a numerical rating that indicates the proficiency of an agent in a certain skill. The skill competence level can range from 1 (lowest) to 10 (highest). A supervisor can modify the skill competence level of an agent by using the Cisco Unified CCX Administration web interface and navigating to Subsystems > RmCm > Resources. For more information on how to modify the skill competence level of an agent, see the Cisco Unified Contact Center Express Administration Guide, Release 10.0 (1), Chapter: Unified CCX Application Configuration, Section: Resources.

The following tasks cannot be performed by a supervisor who does not have administrative privilege:

Delete a resource group: A resource group is a collection of agents who share common characteristics, such as location, function, or availability. A resource group can be used to organize agents for reporting and administration purposes. Only an administrator can delete a resource group by using the Cisco Unified CCX Administration web interface and navigating to Subsystems > RmCm > Resource Groups. For more information on how to delete a resource group, see the Cisco Unified Contact Center Express Administration Guide, Release 10.0 (1), Chapter: Unified CCX Application Configuration, Section: Resource Groups.

Create a resource: A resource is an entity that can handle customer contacts, such as an agent, a supervisor, or an IVR port. A resource can be associated with one or more resource groups, teams, and skills. Only an administrator can create a resource by using the Cisco Unified CCX Administration web interface and navigating to Subsystems > RmCm > Resources. For more information on how to create a resource, see the Cisco Unified Contact Center Express Administration Guide, Release 10.0 (1), Chapter: Unified CCX Application Configuration, Section: Resources.

Delete a skill: A skill is a competency that an agent possesses, such as language, product knowledge, or technical expertise. A skill can be assigned to one or more agents and CSQs. Only an administrator can delete a skill by using the Cisco Unified CCX Administration web interface and navigating to Subsystems > RmCm > Skills.

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.

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 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.

 Cisco Unified CCX Standard license includes the database steps library, which allows the script to access and manipulate data from external databases using SQL queries. The database steps library can be used to create, update, delete, or query records from any JDBC-compliant database, such as Microsoft SQL Server, Oracle, or MySQL. The database steps library can also be used to store session data, such as caller input or agent information, in a database table for later retrieval or reporting. The database steps library is useful for creating dynamic and personalized applications that can interact with external data sources.

The other options are incorrect because they are not included in the Cisco Unified CCX Standard license. The ICM steps library is only available with the Cisco Unified CCX Premium license, and it allows the script to integrate with the Cisco Unified Intelligent Contact Management (ICM) system for routing and reporting purposes. The email steps library is also only available with the Cisco Unified CCX Premium license, and it allows the script to send and receive email messages from customers or agents. The document steps library is available with the Cisco Unified CCX Enhanced or Premium licenses, and it allows the script to read and write documents from the local file system or a remote server using FTP or HTTP protocols. The document steps library can be used to store or retrieve data in XML, CSV, or plain text formats. References := Cisco Unified Contact Center Express Editor Step Reference Guide, Release 12.5(1) SU3, Chapter 2: Unified CCX Editor Step Reference, Database Steps, page 2-15.

 In a typical Cisco Unified CCX agent web chat deployment for an online retail shop, Cisco SocialMiner can be deployed in the demilitarized zone (DMZ). The DMZ is a network segment that lies between the Internet and the corporate network, and it provides a layer of security and isolation for the servers that are exposed to the public. Cisco SocialMiner is a server that enables social media customer care by capturing and routing social contacts from various sources, such as web chat, email, Twitter, and Facebook. By deploying Cisco SocialMiner in the DMZ, the online retail shop can offer web chat services to its customers without exposing the Cisco Unified CCX server or the agent desktops to the Internet. Cisco SocialMiner acts as a proxy between the web chat clients and the Cisco Unified CCX server, and it communicates with the Cisco Unified CCX server using a secure HTTPS connection. The web chat clients can access Cisco SocialMiner using a public URL, and Cisco SocialMiner can also access external social media sources if needed. References: Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 - Module 2:Implement a Cisco Unified Contact Center Express System - Lesson 2: Implement Cisco Unified CCX Web Chat - Topic: Cisco Unified CCX Web Chat Deployment Model

The option that enables you to monitor previous agent seat license usage is port and agent seat utilization historical report in Cisco Unified Intelligence Center. This report provides information about the number of agent seats and IVR ports that are in use for a specified time period. You can use this report to track the peak and average utilization of agent seats and IVR ports, and compare them with the licensed capacity. You can also filter the report by node, license package, and date range.

The other options are not correct because:

traffic analysis historical report provides information about the call traffic and service level for each CSQ and application. It does not show the agent seat license usage.

port-monitoring tool in Cisco Unified Communications Manager Real-Time Monitoring Tool allows you to monitor the status and statistics of the voice gateway ports that are registered with Cisco Unified Communications Manager. It does not show the agent seat license usage.

overall Cisco Unified CCX stats in Cisco Unified Communications Manager Real-Time Monitoring Tool shows the overall status and performance of the Cisco Unified CCX system, such as the number of active calls, agents, sessions, triggers, and chat contacts. It does not show the previous agent seat license usage.

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:

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
