Which solution should the consultant recommend?

Northern Trail Outfitters (NTO) is the holding company of three subsidiaries: Universal Containers, Ursa Major Solar, and Cloud Kicks. NTO recently purchased Marketing Cloud and has asked its consultant to recommend a scalable business unit (BU) hierarchy. They don’t plan on executing any marketing campaigns on behalf of the NTO holding company, but NTO employees would like access to all subscribers and aggregate reporting. Additionally, each subsidiary business will be regularly running campaigns and should have their own branding, content, and subscribers.

Which solution should the consultant recommend?
A . One parent BU and two child BUs with their own Sender Authentication Packages.
B. One parent BU with three additional private domains.
C. One parent BU and one child BU
D. One parent BU and three child BUs with their own Sender Authentication Packages.

Answer: D

Explanation:

To recommend a scalable business unit hierarchy for Northern Trail Outfitters and its three subsidiaries, the consultant should suggest one parent BU and three child BUs with their own Sender Authentication Packages. This will allow each subsidiary business to have their own branding, content, and subscribers, as well as access to aggregate reporting and shared subscribers from the parent BU. Each child BU should have its own Sender Authentication Package to authenticate its email sends with its own domain and branding.
