This FC0-U61 practice question tests your understanding of software development concepts. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer needs to store a list of employee names. Which data structure is most appropriate?
String
Why wrong: A string holds a single text value, not a collection.
Array
An array can hold multiple values of the same type, like a list of names.
Boolean
Why wrong: A Boolean only holds true or false, not a list.
Integer
Why wrong: An integer holds a single number, not multiple names.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
String
Why it's wrong here
A string holds a single text value, not a collection.
Array
Why this is correct
An array can hold multiple values of the same type, like a list of names.

Boolean
Why it's wrong here
A Boolean only holds true or false, not a list.
Integer
Why it's wrong here
An integer holds a single number, not multiple names.
Common exam traps
The trap here is that candidates may 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.
Detailed technical explanation
In most programming languages, arrays are stored as contiguous blocks of memory, allowing O(1) access to any element by index. For a list of employee names, a dynamic array (e.g., ArrayList in Java, list in Python) automatically resizes as names are added, providing both flexibility and efficient iteration. Real-world scenarios like generating a payroll report require iterating over such a list, where arrays are the foundational structure.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
