Which option does a service graph template contain?

A group of logical devices is part of a device cluster, which is instantiated from a meta-device, rather than being the direct content of a service graph template itself.

A collection of user steps is not a standard or defined component of a service graph template's structure within Cisco ACI.

A group of network configurations is too broad and does not specifically describe the abstract, reusable building blocks that comprise a service graph template.

A service graph template in Cisco ACI consists of a collection of meta-devices, which are abstract representations of network services or functions like firewalls or load balancers. These meta-devices are later instantiated as concrete device clusters during service graph deployment, enabling policy-driven service insertion.
