[All DP-700 Questions]

You have a Fabric workspace that contains a write-intensive warehouse named DW1. DW1 stores staging tables that are used to load a dimensional model. The tables are often read once, dropped, and then recreated to process new data.

You need to minimize the load time of DW1.

What should you do?

  • A. Enable V-Order.
  • B. Create statistics.
  • C. Drop statistics.
  • D. Disable V-Order.

Selected Answer: D
Option A is wrong, V-Order is enabled by default, there wouldn’t be a need to enable it again, even if not enabled, In staging scenarios like this—where tables are short-lived, often read once, and then dropped—read performance is not critical. The focus is instead on minimizing. V-Order introduces an average of 15% overhead on write times, which can negatively impact scenarios where load time is the top priority. Option D is correct: you can avoid the write-time overhead associated with V-Order optimization, making it the most suitable choice for your requirements.

Disable V-Order - This avoids the write-time overhead of applying V-Order optimization Perfect for staging scenarios where: Tables are short-lived Read performance is not the priority Load time is more important

V-Order is a write time optimization, has a 15% impact on average write times, but results in an average of 10% faster read times, with some scenarios up to 50%. https://learn.microsoft.com/en-us/fabric/data-engineering/delta-optimization-and-v-order?tabs=sparksql
