PEGA-CERTIFIED-DATA-SCIENTIST sample questions

2 questions from the PEGA-CERTIFIED-DATA-SCIENTIST practice set, with the answer and explanation.

  1. Question 1
    A bank wants to predict which customers will accept a credit card offer, using past campaigns where each response was recorded. Which modeling approach fits this need?
    • A.
      Supervised learning with a labeled response outcome
    • B.
      Unsupervised clustering that ignores the recorded responses
    • C.
      Reinforcement learning that rewards offers in real time without any history
    • D.
      Dimensionality reduction that removes the response column before modeling
    Show answer

    Correct answer:

    • A.
      Supervised learning with a labeled response outcome

    Explanation

    Recorded accept or decline outcomes provide labels, so a supervised classification model can learn to estimate each customer's propensity to respond. Unsupervised clustering is the most tempting distractor, because it groups customers well, but it cannot be scored against the known responses. Reinforcement learning and removing the response column do not fit a labeled history.
  2. Question 2
    In a predictive model, a higher AUC value always means the model will perform better in production than a model with a lower AUC.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • B.
      False

    Explanation

    This is false. AUC measures ranking ability on the evaluation data, so it is useful for comparing candidates but does not guarantee production results. Data leakage, drift and changes in the customer mix can make a high-AUC model underperform once deployed.
