To enable Data Access audit logging across the company while excluding the CustomerService folder projects, the correct approach is to enable the logging at the organization level and then configure exempted principals to include users of the CustomerService folder. This method ensures that audit logging is applied broadly across the organization but excludes specific users or groups as needed. Option A correctly describes this approach by enabling logging at the organization level and specifying the CustomerService folder users as exempted principals. Option B does not address the requirement to exclude the CustomerService folder. Option C suggests enabling logging for all projects and folders except the CustomerService folder, which is not practical or efficient for large organizations. Option D suggests enabling logging for all projects and folders and then exempting the CustomerService folder users, which is similar to Option A but less efficient because it implies enabling logging at a more granular level before applying exemptions.
