200-901 Software Development and Design Practice Question
This 200-901 practice question tests your understanding of software development and design. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 Python function needs to accept a variable number of keyword arguments. Which parameter syntax should be used?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
**kwargs
In Python, the **kwargs syntax allows a function to accept a variable number of keyword arguments by collecting them into a dictionary. This is the correct parameter syntax for handling arbitrary keyword arguments, as specified in Python's function definition rules.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between *args (positional arguments) and **kwargs (keyword arguments), and candidates mistakenly choose *kwargs or confuse the syntax with other operators like &.
Detailed technical explanation
How to think about this question
Under the hood, **kwargs creates a dictionary where the parameter names become string keys and their corresponding values are stored as dictionary values. This is particularly useful in frameworks like Flask or Django for passing configuration options or in wrapper functions that need to forward arbitrary keyword arguments to another function using the ** unpacking operator.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 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.
