I thought Custom Vision was for images, not time series data.

Cognitive Search isn’t even relevant here, come on!

Wait, are we sure it can handle 5,000 datasets efficiently?

Totally agree, it’s designed for identifying unusual values.

Form Recognizer and Custom Vision don't seem relevant here, but I can't recall the exact reasons why.

I feel like we had a practice question similar to this, and Anomaly Detector was definitely the answer there too.

I'm not entirely sure, but I remember something about Cognitive Search being more for indexing and searching data rather than detecting anomalies.

I think we discussed the Anomaly Detector in class, it seems like the right choice for identifying unusual values in time series data.

I've got a good strategy here. I'll eliminate the options that don't seem to match the personas I know an ISE node can have, and then select the best fit from the remaining choices.

Okay, I think I've got it. The two metrics we need are the number of defects found during the requirements review and the total number of defects attributable to requirements, found across all the development phases. This will help us evaluate how effective the requirements review was in identifying and addressing issues early on.

I think the answer is A. The question specifically mentions configuring the number of threads in a portable way, and the ManagedExecutorService should allow us to do that programmatically.
