Which type of Extensibility allows for the sharing and extension of dimensions?

• A. Horizontal
• B. Vertical
• C. Shared
• D. Operational

Answer: (A)

Horizontal extensibility lets a dimension be shared across multiple applications and individually extended with new members or attributes. This means you can reuse a single dimension in different contexts while growing its structure as needs evolve, keeping governance consistent and avoiding duplicate copies. When a dimension needs to be used widely and evolve in one place, horizontal is the fit. The other options don’t combine both sharing across contexts and the ability to extend the dimension in one centralized approach.
