AIF-C01 Practice Question 91: Image Moderation Rekognition

AWS Certified AI Practitioner (AIF-C01) · Test 10 · question 1 of 10

Fundamentals of AI and MLeasy

A photo-sharing startup wants to automatically flag explicit or violent images that users upload, before the images are shown to others. The team has no machine learning expertise and wants to call a managed API rather than train a model. Which AWS service should they use?

Show answer and explanation

Answer:

C. Amazon Rekognition

Amazon Rekognition is a *"cloud-based image and video analysis service"* that adds computer vision to applications with no ML expertise required. Its unsafe content detection feature can *"detect and filter explicit, inappropriate, and violent content"* in images and videos and returns granular labels with confidence scores, which is exactly a moderation workflow (option C).

- A is wrong because Amazon Comprehend analyzes text (sentiment, entities, key phrases). It does not inspect image content. - B is wrong because Amazon Textract extracts printed and handwritten text and structured data from documents. It does not judge whether an image is unsafe. - D is wrong because Amazon Transcribe converts speech in audio to text. It does not process images.
