You work for a sports wagering company as a machine learning specialist. Your team is responsible for building the machine learning models that produce the sports wager line for the NFL (National Football League) games each week. You are working on the line versus the spread model. For this model, you have chosen the XGBoost algorithm. You have trained your model and deployed it to Amazon SageMaker Hosting Services where you are now ready to send inference requests to your model.
You are sending requests to your inference endpoint, but you are seeing that your inferences are failing. Which of these would NOT be the source of the problem? (Select TWO)

Answer options:

A.You have serialized your inference request in the text/csv format.
B.You have serialized your inference request in the text/tsv format.
C.You have serialized your inference request in the text/libsvm format.
D.You have serialized your inference request in the application/json format.

Answers: A, C
Option A is correct. Inference endpoints built using the XGBoost algorithm only support the text/csv, recordio-protobuf, and text/libsvm request formats.
Option B is incorrect. Inference endpoints built using the XGBoost algorithm only support the text/csv, recordio-protobuf, and text.libsvm request formats. Your inference request will fail if you serialize your inference request using the text/tsv format.
Option C is correct. Inference endpoints built using the XGBoost algorithm only support the text/csv, recordio-protobuf, and text/libsvm request formats.
Option D is incorrect. Inference endpoints built using the XGBoost algorithm only support the text/csv, recordio-protobuf, and text.libsvm request formats. Your inference request will fail if you serialize your inference request using the application/json format.
