The correct answer is Rename existing DLP rules to match the new naming convention.

This action is not typically part of the policy design process because design work is focused on defining what to detect how to protect it and how alerts and remediation should work. Renaming rules is an administrative or migration activity that may occur after policies are created approved and deployed.

Decide whether to start from a built in policy template or to create a custom policy is part of the design process because choosing a template or building custom rules determines the detection approach and the baseline controls to use.

Document the detailed configuration for each policy and review the settings with stakeholders is also part of the design process because documenting configurations and reviewing them with stakeholders ensures the policies meet business requirements and compliance obligations.

Review the official Data Loss Prevention guidance and policy reference materials is part of the design workflow because official guidance provides best practices patterns and examples that inform accurate and effective policy configuration.
