What is the common property shared by all IPD block types?

• A. Execution Conditional Formula: If true or undefined, the block executes; otherwise it is skipped
• B. User Interaction required for execution
• C. It enforces data encryption
• D. It requires a database connection

Answer: (A)

All IPD blocks share a gating mechanism called the Execution Conditional Formula. This formula determines whether a block runs: if the condition is true or left undefined, the block will execute; if the condition is false, the block is skipped. This uniform way to control flow applies to every block type, allowing dynamic, data-driven sequencing without needing separate logic for each block. The other traits—needing user interaction, enforcing encryption, or requiring a database connection—aren’t universal across all IPD blocks, since some blocks run automatically and may or may not involve security or data sources depending on the scenario.
