  1. The given data points from classes A and B can be linearly separated using aHard-margin SVM.
  2. Points (2, 2) from class 1 and (3, 3) from class 0 will be on the decisionboundary or support vectors.
  3. A Soft-margin SVM would be a more robust choice than a Hard-margin SVM forthis dataset as the dataset is not linearly separable.
  4. A perceptron model and a hard margin SVM will always give the same decisionboundary for this dataset.
