What are two specifications for UC on UCS Tested Reference Configuration (TRC)? (Choose two.)

A Tested Reference Configuration (TRC) is a pre-tested, validated bill-of-materials for hardware and software. This approach is explicitly "Configuration Based" (A), meaning customers must match the specified components exactly. This contrasts with the more flexible "Specs-based" model, which is rule-based.

Furthermore, a foundational software requirement for all Cisco Collaboration virtualization deployments, including TRCs, is the VMware vSphere hypervisor. It is the only supported hypervisor platform. Therefore, "VMware vSphere is required" (E) is a core specification. The combination of the configuration model's definition (A) and the mandatory hypervisor platform (E) provides the most accurate and fundamental specifications for a TRC.

B. VMware vSphere is optional: This is incorrect. VMware vSphere (ESXi) is the mandatory and only supported hypervisor for Cisco Collaboration virtualization.

C. VMware vCenter is required: While vCenter is also a mandatory component for management and deployment in supported configurations, vSphere (the hypervisor) is the more foundational platform layer, making option E a better choice.

D. defined as Rule Based: This is incorrect. "Rule Based" describes the "Specs-based" hardware support model, which is the alternative to the TRC model.

1. Cisco Collaboration Virtualization Documentation: The official portal www.cisco.com/go/uc-virtualized leads to documentation that defines the support models. The "Hardware Support" section explicitly contrasts "Tested Reference Configurations" (which are configuration-based) with "Specs-based" (which are rule-based).

2. Cisco Collaboration Virtualization Software Requirements: The same documentation outlines the mandatory software components for a supported deployment.

"Virtualization for Cisco Collaboration

" Doc ID: 115979. Section: "Software Requirements." This section states

"VMware vSphere ESXi is the only hypervisor supported for Cisco Collaboration." It also notes

"VMware vCenter Server is required for all deployments

" confirming the requirement but establishing vSphere as the foundational hypervisor.

3. Cisco Unified Communications on Cisco Unified Computing System Documentation: Design guides and configuration examples for UC on UCS consistently refer to TRCs as specific

tested hardware configurations and list VMware vSphere ESXi as a primary software requirement.
