Question
**Scenario Description:** Consider the following scenario: - A table is sorted on an indexed column and has 20,000,000 rows. - Each row is 300 bytes. - Table and index blocks are 4 kilobytes. - Assume 1 kilobyte is approximately 1,000 bytes. **Question:** Assuming the index is sparse, how many entries are in the index? **Answer Options (Drop-down):** - 000,000,000 entries **Interactive Element:** A blue progress bar is displayed, segmented into five sections, with the fifth section highlighted. Below the progress bar, there are two buttons: 1. **Check** (Orange button) 2. **Try again** (Brown button) This scenario involves calculating the number of entries in a sparse index given the parameters of the database table and block sizes.
