PL-900 Practice Question: Demonstrate the capabilities of Power Automate
Your Power Automate flow uses an HTTP action to call a REST API. The API returns a JSON array of objects. You need to process each object and create a record in a SQL Server database. Which actions should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use 'Parse JSON' to define the schema, then 'Apply to each' with 'Insert row' inside.
First, use 'Parse JSON' to define the schema of the JSON array returned by the API. Then, use 'Apply to each' to iterate over each object in the array. Inside the loop, use 'Insert row' to create a record in SQL Server for each object. Option A uses 'Filter array', which only filters the array based on a condition, not iterating; it would still need a loop. Option C uses 'Compose' to store the JSON, but does not provide iteration; 'Insert row' directly would only insert the entire JSON object as a single row, not individual records. Option D uses 'Select' to transform the array's shape, but still lacks the iteration step to process each object individually.
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 'Filter array' to select objects, then 'Insert row'.
Why it's wrong here
'Filter array' filters the array but does not iterate; you still need 'Apply to each'.
- ✓
Use 'Parse JSON' to define the schema, then 'Apply to each' with 'Insert row' inside.
Why this is correct
Parse JSON provides a schema for the array, then 'Apply to each' iterates, and 'Insert row' adds records.
- ✗
Use 'Compose' to store the JSON, then 'Insert row' directly.
Why it's wrong here
'Compose' does not define a schema, and you cannot iterate over the array without 'Apply to each'.
- ✗
Use 'Select' to transform the array, then 'Insert row' with a batch.
Why it's wrong here
'Select' transforms the array but does not iterate; 'Insert row' does not support batch inserts from an array directly.
