Which statement correctly describes a feature of Extensible Dimensionality?

• A. With Extensibility, Member properties can only change within the Dimension they were first created in.
• B. Extensions are done on Base-level Members from the inherited Dimension only.
• C. Members are able to be added as children to a Base-level Member to which data has been loaded.
• D. Horizontal Extensibility applies to all Dimensions equally.

Answer: (B)

Extensible Dimensionality lets you expand a dimension by adding new members, but the extensions are created by attaching new child members to base-level members that come from an inherited dimension. This means the extension work is always performed on those base-level members from the inherited dimension, not on other levels or on members from the local dimension. That is why the statement describing extensions as being done on base-level members from the inherited dimension is the correct one. In other words, you extend the structure specifically through the base-level members provided by the inherited dimension, keeping the original base definitions intact. The other options either misstate how extensibility works (such as limiting changes to the original dimension) or add conditions (like data loading) that aren’t the defining constraint, or imply universal applicability across all dimensions where the feature isn’t treated the same way.
