FC0-U71 Practice Question: A developer needs to store a list of employee…
A developer needs to store a list of employee names. Which data structure is most appropriate?
⚠ Common exam trap
Test-takers frequently confuse a single string with a collection, thinking a string can hold multiple names by concatenation, but the question specifically asks for a 'list' structure, which requires an array or similar collection type.

Correct answer & explanation
✓
Array
An array is the most appropriate data structure for storing a list of employee names because it allows multiple values (strings) to be stored in a single, ordered collection. Unlike a single string, which holds only one value, an array can hold many strings and provides indexed access to each element, making it ideal for lists of items.
