Actual exam question for Amazon's MLS-C01 exam

Question #: 43
Topic #: 2

A city wants to monitor its air quality to address the consequences of air pollution A Machine Learning Specialist needs to forecast the air quality in parts per million of contaminates for the next 2 days in the city As this is a prototype, only daily data from the last year is available

Which model is MOST likely to provide the best results in Amazon SageMaker?

AUse the Amazon SageMaker k-Nearest-Neighbors (kNN) algorithm on the single time series consisting of
the full year of data with a predictor_type of regressor.

BUse Amazon SageMaker Random Cut Forest (RCF) on the single time series consisting of the full year of
data.

CUse the Amazon SageMaker Linear Learner algorithm on the single time series consisting of the full year
of data with a predictor_type of regressor.

DUse the Amazon SageMaker Linear Learner algorithm on the single time series consisting of the full year

Linear Learner is solid, but I wonder about the classifier option in D.

RCF seems interesting, but I’m not sure it’s the best for this.

Wait, can kNN really handle time series data effectively?

I think option C is the way to go for regression tasks.

I feel pretty confident about this one. The question is asking for two approaches, and I think Options C and D both look like solid solutions that meet the requirements.

Self-organization is key here. We have the skills and knowledge on the team to break down these user stories and figure out the necessary tasks. No need to involve the Scrum Master or customer just yet.

Hmm, I'm a little unsure about where exactly to find the Return Reason Codes setup. I'll need to do some searching in the Dynamics 365 portal to locate that. Hopefully it's not buried too deep in the menus.

I think statement I is correct because I remember learning that the present value of unpaid installments can be included in the estate.
