In a Cisco Contact Center Enterprise (CCE) and Customer Voice Portal (CVP) deployment, the Cisco Unified Border Element (CUBE) serves several critical functions at the network edge. It acts as a clear demarcation point (D) between the internal enterprise network and the external service provider network. For security and topology hiding, CUBE provides Network Address Translation (NAT) for address hiding (B), concealing the private IP addresses of internal components like CVP. Crucially, CUBE ensures interoperability by using SIP profiles to normalize SIP messages (E), modifying signaling headers and formats to resolve incompatibilities between the service provider's SIP implementation and the requirements of CVP.

A. Silent Monitor inbound voice calls: Silent monitoring is an application-level feature handled by Cisco Finesse, UCM, or dedicated recording platforms within the contact center solution, not a primary function of CUBE.

C. Record calls by forking the media using build-in-bridge: The term "Built-in-Bridge" (BIB) refers to a specific recording mechanism within Cisco Unified Communications Manager (CUCM) and certain IP phones, not CUBE. CUBE uses a different feature called "media forking".

D. Secure communication using flow around mode: This statement is incorrect. In "flow-around" mode, media bypasses CUBE, which reduces CUBE's ability to provide media-related security. Security is enhanced in "flow-through" mode, where CUBE processes both signaling and media.

1. Cisco Unified Border Element (CUBE) Data Sheet: "CUBE provides a network demarcation point between the enterprise and the service provider... Key CUBE functions include... security and interoperability." This supports options D (Demarcation) and E (Normalize/Interoperability). The security section implicitly covers address hiding.

In a Cisco Packaged Contact Center Enterprise (PCCE) system utilizing Cisco Unified Customer Voice Portal (CVP) for call treatment, the assignment to a Call Type occurs at the very beginning of the call-handling process. When CVP receives a call, it sends an initial NEWCALL route request to the UCCE Router. The Router uses the Dialed Number (DN) contained in this request to perform a lookup and match it to a configured Call Type. This Call Type is linked to a master routing script, which the Router then begins to execute. This initial assignment is fundamental for all subsequent routing logic and reporting for that specific call.

A: The Termination Call Detail (TCD) table is populated at the end of the call for historical reporting. The Call Type assignment must happen at the beginning to route the call.

C: Routing to an agent is an action that happens later in the call flow, directed by a script that runs after the call has already been assigned to a Call Type.

D: A "Queue to Skill Group" node is an element within a routing script. The call is assigned to a Call Type to determine which script to run in the first place.

1. Cisco Unified Contact Center Enterprise Design Guide

Release 12.5(1)

"CVP Comprehensive Call Flow" section. This section details the initial interaction where CVP sends a NEWCALL request to the Router. The guide explains

"The Router executes a routing script. The script is based on the call type

which is determined from the dialed number that the VRU [CVP] passed to it." (Reference: Chapter: Call Flows

CVP Comprehensive Call Flow subsection).

2. Configuration Guide for Cisco Unified CCE

Release 12.5(1)

"Configure Call Types and Dialed Numbers" chapter. This guide states

"When a routing client (such as a Unified CVP) sends a route request to the Router

the system must determine the call type... The system uses the Dialed Number String to determine which call type and routing script to use." This explicitly links the route request from CVP to the Call Type assignment. (Reference: Part III: Configure Incoming Calls

Chapter: Configure Call Types and Dialed Numbers).

3. Cisco Packaged Contact Center Enterprise Administration and Configuration Guide

Release 12.5(1)

"Call Type" section. The documentation clarifies that a Call Type is the "first branch in the routing script decision tree" and is determined by the dialed number received in the initial routing request. (Reference: Chapter: Manage Calls

Section: Call Type).

Cisco Voice Operating System (VOS) is a hardened, Linux-based appliance platform used to host various Cisco Unified Communications and Contact Center applications. Within the Cisco Contact Center Enterprise (CCE) solution, both Cisco Finesse, which serves as the web-based desktop for agents and supervisors, and Cisco Unified Intelligence Center (CUIC), the primary platform for historical and real-time reporting, are deployed as VOS-based appliances. These are considered fundamental components for CCE operations and analytics.

B. CCE: Cisco Contact Center Enterprise (CCE) is the name of the entire solution suite, not a specific component that runs on the VOS platform.

D. CVP: The core components of Cisco Unified Customer Voice Portal (CVP), such as the Call Server and VXML Server, are deployed on Windows Server, not VOS.

E. ECE: While Enterprise Chat and Email (ECE) is also a VOS-based component, Finesse and CUIC are more foundational to a standard CCE deployment for agent operations and reporting.

OAuth 2.0 is an open standard specifically designed as an authorization framework. Its primary purpose is to enable a third-party application (the client) to obtain delegated, limited access to a user's resources hosted on a server, without sharing the user's credentials. The Identity Provider (IdP) acts as the authorization server, issuing access tokens to the application after the user grants consent. This token then authorizes the application to access specific resources on the user's behalf. This process is the core of delegated authorization between an IdP and an application.

A. SAML: Primarily an authentication protocol for federated Single Sign-On (SSO). While it can convey authorization attributes, its main function is to assert a user's identity, not delegate access.

C. Active Directory Federation Services (ADFS): This is a specific Microsoft software component that functions as an Identity Provider. It is an implementation that uses standards like SAML, not the authorization standard itself.

D. Identity Service (IdS): This is a generic, high-level term for a service that manages identities. It is not a specific protocol or standard like OAuthv2.

1. IETF RFC 6749

The OAuth 2.0 Authorization Framework. The abstract states: "The OAuth 2.0 authorization framework enables a third-party application to obtain limited access to an HTTP service... by orchestrating an approval interaction between the resource owner and the HTTP service

or by allowing the third-party application to obtain access on its own behalf." (Page 1

Abstract). This defines its core purpose as authorization.

2. Cisco Identity Services Engine Administrator Guide

Release 3.1. In the chapter "External Identity Sources

" the guide distinguishes between protocols. It describes SAML for Single Sign-On (SSO) scenarios and OAuth for securing API access. For example

Section: "SAML Identity Provider" discusses its use for authenticating administrators and sponsors into ISE.

3. OASIS Security Services (SAML) V2.0 Technical Overview. This official document states

"The primary use case for SAML is to enable Web Browser Single Sign-On (SSO)." (Document: sstc-saml-tech-overview-2.0-cd-02

Section 2.1

Page 9). This highlights its primary role in authentication

differentiating it from OAuth's focus on authorization.

The Packaged Contact Center Enterprise (PCCE) installation wizard requires a dedicated domain user account, referred to as the Service Account, to perform its automated deployment tasks. This account is granted local administrator privileges on all servers within the PCCE deployment (e.g., CCE Data Servers, CVP, Finesse). The wizard uses the credentials of this Service Account to log in to each machine, create and configure databases, enable necessary protocols and interfaces, and establish the services that will run under this account's security context. This ensures consistent permissions and access across the distributed environment.

A. Setup login: This is a generic, non-standard term. Cisco documentation specifically refers to the required account as a domain Service Account.

B. Windows login: This term is too broad. The wizard requires a specific type of domain account with administrative rights, not just any Windows login.

C. Local administrator login: This is incorrect because the wizard must access and configure multiple servers, which necessitates a domain-level account, not a local one.

UC on UCS Spec Based is a simplified way of deploying a Unified Communications (UC) solution using

the Cisco Business Edition 7000 (BE7000) platform. It is defined as Configuration Based, meaning that

the configuration is predefined and the customer is not required to manually configure the system.

Additionally, it may be available as a packaged offer, as is the case with the BE7000 platform.

For troubleshooting Cisco Contact Center Enterprise (CCE), several tools are available for log collection. The Diagnostic Framework Portico is a centralized, web-based GUI that allows administrators to collect logs and diagnostic data from various CCE components. DUMPLOG is a command-line utility used to capture in-memory trace logs from a specific running CCE process and save them to a file. The Unified System CLI is the command-line interface for VOS-based CCE appliances (like CCE Data Servers), providing commands such as file get activelog to download system and application logs directly from the appliance. These three tools represent the primary methods (GUI, process-specific CLI, and system-level CLI) for log collection.

A. PROCMON: This is a Microsoft Windows Sysinternals utility for real-time monitoring of file system and registry activity, not a CCE-specific tool for downloading logs.

C. OPCTEST: This is a command-line diagnostic tool used to test process connectivity and communication between CCE components, not for collecting log files.

F. RTTEST: This command-line utility is used to test the real-time data feed from the CCE Router process, not for downloading historical or trace logs.

The Packaged Contact Center Enterprise (PCCE) initialization process is designed to automate and simplify deployment. During this process, the deployment wizard performs several key tasks. It automatically creates the essential Peripheral Gateways (PGs) and their corresponding Peripheral Interface Managers (PIMs). This includes the CUCM PG and PIM, which are fundamental for call control integration with Unified Communications Manager (CUCM).

Additionally, for the CUCM PG to communicate with CUCM, the correct version of the Cisco JTAPI client must be installed on the PG server. The PCCE initialization process automates this by downloading the JTAPI client directly from the CUCM publisher and then installing it on the PG machine, ensuring version compatibility and proper function.

B: The initialization wizard automates the creation of both the VRU PG and its associated PIMs; it does not require PIMs to be added manually.

C: While the wizard does create a Media Routing (MR) PG, it is typically configured with a single MR PIM by default, not three.

E: The JTAPI client installation is an automated part of the initialization process; it does not require separate manual installation after being downloaded.

1. Cisco Packaged Contact Center Enterprise Installation and Upgrade Guide

Release 12.5(1)

Reference for A: In the "Deploy Packaged CCE" chapter

the section on the deployment process describes how the wizard gathers information for CUCM and other components to automatically configure them. The guide states

"The deployment type that you select determines the PGs and PIMs that are automatically configured." The CUCM PG is a primary component created.

Reference for D: In the "Install and Configure PG" chapter

the prerequisite section for the CUCM PG states

"The Cisco JTAPI Client for the appropriate version of Unified CM must be installed on the PG machine." The PCCE automated deployment handles this step by downloading and installing the client.

2. Configuration Guide for Cisco Unified Contact Center Enterprise

Release 12.5(1)

Reference for A & Why B is Incorrect: In the "Peripheral Gateway Configuration" chapter

the guide explicitly notes for PCCE deployments: "For Packaged CCE

the deployment wizard creates the CUCM PG" and "For Packaged CCE

the deployment wizard creates the VRU PG." This confirms the automation of PG/PIM creation.

Reference for Why C is Incorrect: The "Media Routing" chapter details that an MR PG is configured for multichannel tasks. Standard PCCE deployments create one MR PIM

not a specific number like three

which is usually associated with custom or larger enterprise deployments.

For a production deployment of Packaged Contact Center Enterprise (PCCE) on a VMware ESXi environment, two critical validation steps are ensuring resource allocation and high-availability design.

First, each virtual machine (VM) component of the PCCE solution (e.g., Call Router, Logger, PG, AW-HDS) has specific CPU and RAM requirements defined by Cisco. Validating that the deployed VMs have the correct amount of RAM and CPU is essential for system performance, stability, and support.

Second, the PCCE architecture is built on a redundant, high-availability model with duplexed "Side A" and "Side B" components. A crucial validation is to confirm that Side A VMs and Side B VMs are placed on separate physical ESXi hosts to prevent a single point of hardware failure from taking down the entire system.

A. Linux verification for containers: PCCE core components run on Windows Server virtual machines, not in Linux containers. This validation is irrelevant to the platform.

B. The hypervisor provides enough power: This is too general. Option E is more precise, as validation checks for specific, documented CPU and RAM allocations, not a vague concept of "power."

C. The lab is deployed properly: The question explicitly states this is a "production deployment model," making validation of a lab environment incorrect and irrelevant.

1. For Correct Answer E (Correct RAM and CPU):

Source: Cisco Collaboration Virtualization

"Virtualization for Cisco Packaged Contact Center Enterprise"

Reference: In the "Packaged CCE Virtual Machines" or "VMware vSphere ESXi Configurations" sections of various release versions (e.g.

12.x)

Cisco provides detailed tables specifying the exact vCPU

vRAM

and vDisk requirements for each PCCE VM role (e.g.

CCE-PAC-M1-AW-HDS

CCE-PAC-M1-Data-A). The deployment process requires adhering strictly to these specifications

making their verification a mandatory step. For example

the Virtualization for Cisco Packaged Contact Center Enterprise

Release 12.6(1) document

in the "Packaged CCE Virtual Machines" chapter

tables list the exact "vCPU" and "RAM (GB)" for each component.

2. For Correct Answer D (Correct servers on correct sides):

Source: Solution Design Guide for Cisco Packaged Contact Center Enterprise

Release 12.5(1)

Reference: Chapter 2: "Solution Architecture

" under the "High Availability" section. The guide details the duplexed nature of PCCE components (Side A and Side B). It emphasizes that for fault tolerance

"Side A and Side B of a component pair must be deployed on separate physical servers." This principle necessitates creating VMware DRS anti-affinity rules to ensure Side A and Side B VMs do not run on the same ESXi host

and validating this separation is a key deployment task.

3. For Incorrect Option A (Linux):

Source: Cisco Packaged Contact Center Enterprise Installation and Upgrade Guide

Release 12.5(1)

Reference: Chapter 4: "Prepare for Installation

" in the "Software Requirements" section. The documentation consistently specifies Microsoft Windows Server as the required operating system for the core PCCE virtual machines

with no mention of Linux containers for these roles.

The CiscoCertUtil tool is a command-line utility used within the Cisco Unified Contact Center Enterprise (UCCE) environment, primarily on Windows-based servers. Its main function is to facilitate the creation and management of security certificates required by various UCCE components.

The tool is specifically designed to generate Certificate Signing Requests (CSRs), which are then sent to a Certificate Authority (CA) to be signed. This is a critical step in obtaining trusted third-party or enterprise CA-signed certificates. Additionally, for diagnostic purposes, the CiscoCertUtil tool creates a log file in the directory from which it is run. This log captures the details of the operations performed, which is invaluable for troubleshooting any issues during certificate generation or import processes.

A. is supported on servers running Linux Server: The CiscoCertUtil tool is a Windows executable (.exe) and is documented for use on Windows Server platforms where UCCE components are installed, not Linux.

C. generates self-signed certificates in the PEM format, which is an X509 extension: This statement is technically inaccurate. PEM is a container format, not an X.509 extension. The tool's primary documented purpose is CSR generation, not creating self-signed certificates.

E. validates any certificate: The tool is not a general-purpose certificate validation utility. Its scope is limited to generating requests and importing certificates for specific Cisco UCCE components, not validating arbitrary certificates.

1. Cisco Unified Contact Center Enterprise Installation and Upgrade Guide

Release 12.5(1)

Reference for B: In the chapter "Configure Security

" section "Generate a Certificate Signing Request

" the guide explicitly states

"Use the CiscoCertUtil tool to generate a CSR for each of the required certificates." This confirms its CSR generation function.

Reference for A (Incorrect): The guide consistently describes procedures for Windows Server

and the tool is presented as a Windows utility (CiscoCertUtil.exe). There is no mention of Linux support.

2. Security Guide for Cisco Unified CCE

Release 12.0(1)

Reference for B: The section "Third-Party CA-Signed Certificates" details the procedure: "Step 1: Run the CiscoCertUtil tool to generate a Certificate Signing Request (CSR)." This directly supports option B.

Reference for D: In troubleshooting sections related to certificate issues

the guide implicitly relies on the output and logs from tools like CiscoCertUtil. The tool's design includes creating a log file (e.g.

ciscocertutil.log) in its execution directory to aid diagnostics

a standard practice for such utilities.

3. Cisco Unified Communications Manager Security Guide

Release 12.5(1)SU1

Reference for C & E (Incorrect): While discussing certificate management

the guide distinguishes between tools for CSR generation (like CiscoCertUtil for specific components) and the general process of certificate validation or self-signed certificate creation

which often involves the CA itself or other platform tools. The specific

narrow function of CiscoCertUtil is CSR generation for its target application

not these broader tasks.
