- A
Train an image classification model (CNN) on screenshots of log graphs
Why wrong: Unnecessary; direct log data is structured, not image-based.
- B
Use a time-series anomaly detection model (e.g., Isolation Forest with sliding windows)
Isolation Forest works on numerical features; sliding windows capture temporal patterns.
- C
Train a supervised classification model (e.g., XGBoost) on extracted features with the labels
If labeled data is available, supervised models can effectively detect anomalies.
- D
Use a code generation model to fix the anomalies automatically
Why wrong: Code generation does not detect anomalies; it generates code from prompts.
- E
Build a recommendation system based on user activity logs
Why wrong: Recommendation systems serve content; not for anomaly detection.
AI0-001 Implementing AI Solutions Practice Question
This AI0-001 practice question tests your understanding of implementing ai solutions. 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 use AI to automatically detect anomalies in server log data. The data is time-series and labeled with 'normal' and 'anomaly' for the past year. Which TWO techniques are appropriate for this use case?
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 a time-series anomaly detection model (e.g., Isolation Forest with sliding windows)
Option B is correct because Isolation Forest with sliding windows is a well-suited unsupervised technique for detecting anomalies in time-series data by isolating outliers in feature windows extracted from the log stream. Option C is correct because the company has labeled data ('normal' and 'anomaly'), enabling a supervised classification model like XGBoost to learn patterns from engineered features and predict anomalies accurately.
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 supervised and unsupervised techniques, and candidates mistakenly choose an unsupervised method (like Isolation Forest) when labeled data is available, or they overlook that both supervised and unsupervised approaches can be valid depending on the data and problem framing.
Detailed technical explanation
How to think about this question
Isolation Forest works by recursively partitioning the data with random splits; anomalies are isolated quickly (shorter path lengths) because they are few and different. When combined with sliding windows, each window captures a fixed-length segment of the log sequence, allowing the model to detect contextual anomalies (e.g., a sudden spike in error codes) that deviate from the normal temporal pattern. In supervised approaches like XGBoost, feature engineering might include rolling statistics (mean, variance, count of specific log levels) over time windows, and the model learns decision boundaries that separate normal from anomalous patterns using the provided labels.
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.
