When configuring an activation in Data Cloud, the fundamental steps involve defining what data to send and where to send it. The user must first select the segment, which represents the specific cohort of unified individuals to be activated. Next, they must select the contact points (for example, email address or phone number) that the target system will use for outreach. These two selections are mandatory for defining the activation's payload and destination contacts.

A. Adding additional attributes is an optional step to enrich the activation file with more data about the individuals, but it is not a required action to create the activation.

D. The calculated insight is used to create the segment, but the activation process itself requires selecting the resulting segment, not the calculated insight directly.
