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.
