Which product includes prebuilt templates that are available to be used to customize fabric deployments?

Cisco Tetration (now Cisco Secure Workload) focuses on workload protection, application dependency mapping, and security policy enforcement, not on providing templates for fabric deployments.

Cisco Data Center Network Manager (DCNM) is designed for comprehensive management, automation, and orchestration of Cisco Nexus and MDS switches. It features robust capabilities for fabric provisioning, including prebuilt templates and wizards that allow engineers to quickly deploy and customize various data center fabric types, such as VXLAN EVPN or SAN fabrics.

Cisco ACI uses a policy-driven, intent-based model to abstract network configuration, rather than offering 'prebuilt templates' for traditional fabric deployments in the same way DCNM does.

Cisco UCS Manager is used for managing Cisco UCS servers and their associated fabric interconnects, not for deploying or customizing broader data center network fabrics.
