✑ Sentiment analysis: Identifies positive, negative, and neutral sentiments from speech and visual text.
✑ Face detection: Detects and groups faces appearing in the video.

As of June 2020 the video indexer is not available for customers. So a high chance that this question will not appear in the exam ;)

I think, the question might still come up, since they have only changed the name of the service. https://docs.microsoft.com/en-us/azure/azure-video-analyzer/video-analyzer-for-media-docs/video-indexer-overview
