The Cisco UC on UCS specs-based virtualization support model is a virtualization approach for Cisco Unified Communications (UC) applications that is based on predefined specifications. The approach enables the deployment of UC applications on Cisco Unified Computing System (UCS) servers, using VMware virtualization technology. Here are the two statements that are true about this support model:

B. It has a rule-based approach. The Cisco UC on UCS specs-based virtualization support model is a rule-based approach that involves the use of predefined specifications to ensure compatibility between UC applications and the UCS servers. These specifications define the exact hardware and software configurations that are required for the virtualized environment to work properly. For example, the specs might specify the number of virtual CPUs, the amount of RAM, and the storage requirements for a particular UC application. The rule-based approach helps to ensure that the virtualized environment is stable and reliable, with minimal risk of compatibility issues.

E. VMware vCenter is optional with this support model. VMware vCenter is a management tool that provides centralized control and monitoring of VMware virtualized environments. With the Cisco UC on UCS specs-based virtualization support model, the use of VMware vCenter is optional. Administrators can choose to use vCenter to manage their virtualized environment or they can use other tools that are compatible with VMware. However, using vCenter can provide additional benefits, such as enhanced monitoring and performance tuning capabilities.

A, C, and D are false statements:

A. It has a configuration-based approach. This statement is incorrect. The Cisco UC on UCS specs-based virtualization support model is not a configuration-based approach. Instead, it is a rule-based approach, as explained above.

C. It has less hardware flexibility compared to the third-party server specs-based support model. This statement is incorrect. The Cisco UC on UCS specs-based virtualization support model provides hardware flexibility that is comparable to the third-party server specs-based support model. Both models enable the use of third-party servers that meet the required specifications for virtualizing UC applications.

D. It has less hardware flexibility compared to the UC on UCS TRC support model. This statement is incorrect. The UC on UCS TRC (Tested Reference Configuration) support model is a more prescriptive approach that specifies the exact hardware and software configurations that are required for virtualizing UC applications. The specs-based support model provides more hardware flexibility, as it enables the use of third-party servers that meet the required specifications, whereas the TRC support model only allows the use of Cisco UCS servers that are certified for use with the UC applications.
