1. Which of the following are good candidate problems for using XGBoost? (Choose 3)
2. Which of the following might be used to focus a model on most relevant features?
3. You are being asked to develop a model to predict the likelihood that a student will pass a certification exam based on hours of study. Of the options given, what would be the best approach to this problem?
4. When analyzing a set of one-hot encoded data you realize that, while there is a massive amount of data, most of the values are absent. This is expected given the type of data, but what built-in SageMaker algorithm might you choose to work with this data?

6. Which of these examples would be considered as introducing bias into a problem space? (Choose 2)
7. Which best describes SGD in common terms?
8. While using K-Means, what does it mean if we pass in k=4 as a hyperparameter?
9. To remove inconsistency in a process, you have created a very specific step-by-step process for patching servers. How would this best be described?
10. You have been asked to help develop a vision system for a manufacturing line that will reorient parts to a specific position using a robotic arm. What algorithm might you choose for the vision part of this problem?
11. You are on a personal quest to design the best chess playing model in the world. What might be a good strategy for this objective?
