HOTSPOT You are building an app that will process incoming email and direct email messages to either French or English language support teams. Which Azure Cognitive Services API should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. 
Yeah, I'd use the /text/analytics/v3.1/languages endpoint for this. It's all about language detection, not translation, so Text Analytics is the right API here. Translator is only needed if you actually want to convert between languages. Pretty sure that's what the exam expects but open to any other views!
Totally agree, this needs language detection not translation. The /text/analytics/v3.1/languages endpoint on eastus.api.cognitive.microsoft.com is made for this scenario. Translator API is only if you want to convert between languages. Pretty sure that's what's expected here, but happy to discuss if someone thinks otherwise.
Is the language detection endpoint from Text Analytics always the preferred option for just sorting email by language? Seems like both English and French routing in this context would use /text/analytics/v3.1/languages with the eastus region endpoint, but want to be sure.
Yeah this is just about language detection, so the Text Analytics endpoint is the right pick. The translator one is for actual translating, not just figuring out what language it is. If I misunderstood, let me know!
