- A
Supervised classification with logistic regression
Why wrong: Requires labeled data, which is not available here.
- B
Semi-supervised learning with a small labeled set
Why wrong: Semi-supervised still requires some labels, which are not available.
- C
Unsupervised clustering using K-means
K-means clustering groups similar tickets without labels.
- D
Reinforcement learning with a reward function
Why wrong: RL is for sequential decision-making, not static grouping.

AI0-001 AI Concepts and Techniques Practice Question
This AI0-001 practice question tests your understanding of ai concepts and techniques. 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 company wants to automatically group customer support tickets into categories (e.g., billing, technical, account) without pre-labeled data. Which machine learning approach should they 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
✓
Unsupervised clustering using K-means
Option C is correct because the company has no pre-labeled data, which means supervised learning (which requires labeled examples) is not feasible. Unsupervised clustering, such as K-means, groups data points into clusters based on feature similarity without needing any labels, making it ideal for automatically discovering categories like billing, technical, or account from raw ticket text.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between supervised and unsupervised learning by presenting a scenario with 'no pre-labeled data' to trick candidates into choosing semi-supervised learning (Option B) because it sounds like a compromise, but the correct answer is always unsupervised clustering when zero labels are available.
Detailed technical explanation
How to think about this question
K-means clustering partitions n observations into k clusters by minimizing within-cluster variance, typically using Euclidean distance. A subtle behavior is that the algorithm is sensitive to initial centroid placement and the choice of k, often requiring techniques like the elbow method or silhouette analysis to determine the optimal number of clusters. In a real-world scenario, a company might preprocess ticket text using TF-IDF vectorization before applying K-means to group similar issues.
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 AI0-001 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.
