Alteryx-Core Data Preparation Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Use the Auto Field tool to optimize data types.

  Why this is correct

  The Auto Field tool is specifically designed to minimize memory usage by assigning the smallest possible data type to each column. By running this early in the workflow, you can drastically reduce the memory overhead and prevent the insufficient memory errors described in the exhibit.

• ✗

  Increase the computer's physical RAM.

  Why it's wrong here

  While more RAM helps, it is not a 'workflow strategy'. The best practice is to optimize the workflow configuration itself to ensure it runs efficiently on current hardware. Relying on hardware upgrades to fix inefficient workflows is not a scalable or sustainable professional data engineering solution.

• ✗

  Use the Sort tool to organize data.

  Why it's wrong here

  Sorting often requires high memory usage because the entire dataset must be loaded into memory to determine the order. Adding a Sort tool to an already memory-constrained workflow would likely worsen the problem rather than resolve it, as it adds further memory pressure.

• ✗

  Disable the cache feature.

  Why it's wrong here

  Disabling caching does not solve the memory issues associated with processing a large volume of records. The cache feature actually helps performance by storing intermediate results. The core issue is the memory required for the operation, not the caching of the workflow's intermediate outputs.
