The answer is to retrain the model using images captured under various lighting conditions, employing data augmentation. This is correct because data augmentation artificially expands the training dataset by applying transformations—like brightness shifts, contrast adjustments, or noise injection—which forces the model to learn invariant features rather than memorizing specific lighting patterns, directly improving model robustness. On the Microsoft Azure AI Engineer Associate AI-102 exam, this scenario tests your understanding of how to address domain shift and overfitting in computer vision pipelines; a common trap is assuming preprocessing alone (like histogram equalization) can fix the issue, but without augmented training data the model lacks exposure to the full range of real-world conditions. For a quick memory tip, think “Augment to Adapt”—if the lighting changes, your training data must change too, not just your image filters.
AI-102 Plan and manage an Azure AI solution Practice Question
This AI-102 practice question tests your understanding of plan and manage an azure ai solution. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 is using Azure AI Vision to analyze images from a manufacturing line. The solution must detect defects in real-time. The team discovers that the model's accuracy drops significantly when images are captured under different lighting conditions. What is the best approach to improve the model's robustness?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Retrain the model using images captured under various lighting conditions, using data augmentation.
Option C is correct because retraining with augmented data (different lighting) directly addresses the issue. Option A is wrong because it only adds variation but does not ensure the model generalizes to new conditions. Option B is wrong because a different model (e.g., Custom Vision) may still need training data. Option D is wrong because pre-processing alone cannot compensate for lack of training data.
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.
✗
Apply image pre-processing to normalize lighting before sending to the model.
Why it's wrong here
Pre-processing helps but does not address the root cause if the model was not trained on varied data.
✗
Increase the number of training images without varying lighting conditions.
Why it's wrong here
More images without variation will not help the model generalize to different lighting.
✓
Retrain the model using images captured under various lighting conditions, using data augmentation.
Why this is correct
Including diverse lighting in training data and using augmentation improves robustness.
Clue confirmation

Read the scenario before looking for a memorised answer.
✗
Use a pre-built model from Azure AI Vision instead of a custom model.
Why it's wrong here
Pre-built models are not specialized for defect detection in manufacturing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
