This AI-102 practice question tests your understanding of implement computer vision solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Which TWO features are available in Azure Computer Vision but not in Azure Custom Vision?
Object detection
Why wrong: Both can detect objects; Custom Vision requires training.
Image classification
Why wrong: Both services can classify; Custom Vision requires training.
Face detection
Why wrong: Not a core Computer Vision feature; separate Face API.
Optical character recognition (OCR)
Pre-built OCR only in Computer Vision.
Image captioning
Pre-built captioning only in Computer Vision.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Optical character recognition (OCR)
A and E are correct. Azure Computer Vision provides pre-built optical character recognition (OCR) and image captioning. Custom Vision is for custom models and does not include these pre-built capabilities. B and C are wrong because Custom Vision can do image classification and object detection with custom training. D is wrong because face detection is available in Face API, not directly in Computer Vision.
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.
Object detection
Why it's wrong here
Both can detect objects; Custom Vision requires training.
Image classification
Why it's wrong here
Both services can classify; Custom Vision requires training.
Face detection
Why it's wrong here

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
