5. The IoT operates at ___________ scale.
a) Machine
b) Human
c) Device
d) Sensor
View Answer
Explanation: The IoT operates at machine scale, by dealing with machine to machine generated data. This machine generated data creates discrete observations at very high signal rates.

a) 3-Tier Analytics
b) 2-Tier Analytics
c) 1-Tier Analytics
d) 4-Tier Analytics
View Answer
Explanation: Tier-1 performs individual wind turbine real time performance analytics and optimization.
8. Which tier predicts maintenance?
a) 3-Tier Analytics
b) 2-Tier Analytics
c) 1-Tier Analytics
d) 4-Tier Analytics
View Answer
Explanation: Tier 2 optimizes performance and predicts maintenance needs across the wind turbines in the same wind farm.
9. Which tier is data lake enabled core analytics platform?
a) 4-Tier Analytics
b) 2-Tier Analytics
c) 1-Tier Analytics
d) 3-Tier Analytics
View Answer
Explanation: Tier-3 is the data lake enabled core analytics platform. The tier 3 core analytics platform includes analytics engines, data sets and data management services that enable access to the data.
10. For supporting real time edge analytics, we need to provide detailed data.
a) True
b) False
View Answer
Explanation: To support real time edge analytics, we need to provide detailed data that can flag observations of concern, but then doesn’t overwhelm the ability to get meaningful data back to the core for more broad based strategic analysis.
