A data governance policy violation in Adobe Real-Time CDP occurs when an action, such as activating a segment, conflicts with a policy associated with the data. The C4 label indicates a contractual restriction, which is being violated by sending it to an email destination. To resolve this while upholding the existing policy, the practitioner must alter the action.

The recommended resolutions are:

1. Modify the segment (B): The practitioner can edit the segment definition to remove the specific attribute that carries the C4 label. This makes the segment compliant with the policy, allowing it to be activated.

2. Cancel the activation (C): The practitioner can stop the activation of this segment to the specific destination, thereby ceasing the action that causes the violation.

A. Remove or modify data usage policy: This is incorrect because the question explicitly requires the practitioner to "maintain existing data governance policy," not change it.

D. Remove or modify labels of the dataset: This is incorrect because modifying a data label is only appropriate if the label was applied in error. Changing a correct label to bypass a policy circumvents the governance framework rather than maintaining it.

1. Adobe Experience League - Data Governance Overview: The documentation states

"Data Governance enforces data usage policies to prevent data that is in violation of a policy from being sent to a destination." This confirms that the system's response is to block the activation

making the logical user resolutions either to stop the activation (C) or change what is being activated to make it compliant (B). (See Section: "Data activation")

2. Adobe Experience League - Monitor data governance policy compliance: This document describes the workflow when a violation occurs: "If a policy is violated

the activation workflow is prevented from continuing... Once you have addressed the issue (for example

by removing the... data from the segment)

you can try activating the segment again." This directly supports modifying the segment (B) as a primary resolution. (See Section: "Policy enforcement")
