A developer needs to configure a rendering in order to use dynamic placeholders. Which of the following steps is required? Select all that apply.

To make a rendering support dynamic placeholders you must 1) expose the Dynamic Placeholder fields by inheriting the IDynamicPlaceholder base template in the rendering-parameters template, 2) register each placeholder settings item in the Placeholder(s) field of the rendering item so Experience Editor can recognize and enable the dynamic placeholder, and 3) declare the placeholder key in the placeholder settings item using the “?” (dynamic-token) so Sitecore can append a unique identifier at runtime. A unique key does not have to be hard-coded in the TSX file; Sitecore generates the instance-specific suffix automatically.

D. Dynamic keys are appended automatically by Sitecore; the component code reuses the configured placeholder name and therefore does not require (and must not invent) a new unique key.
