ME1-C02 sample questions

2 questions from the ME1-C02 practice set, with the answer and explanation.

  1. Question 1
    A team must query 500 GB of raw CSV logs stored in Amazon S3 with standard SQL, without loading them into a database first. Which service fits best?
    • A.
      Amazon Athena
    • B.
      Amazon DynamoDB
    • C.
      Amazon ElastiCache
    • D.
      Amazon Aurora
    Show answer

    Correct answer:

    • A.
      Amazon Athena

    Explanation

    Athena runs standard SQL directly on data in S3 without loading it into a database, which suits exploratory feature work. DynamoDB is tempting for fast lookups, but it is a key-value store rather than an engine for scanning CSV files in S3. ElastiCache is an in-memory cache and Aurora is a relational database that requires loading the data first.
  2. Question 2
    Standardizing numeric features to zero mean and unit variance matters most for algorithms that rely on distances or gradient-based optimization.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • A.
      True

    Explanation

    Distance-based methods such as k-nearest neighbors, linear models trained by gradient descent, and neural networks all benefit from standardized inputs. The statement is true. Tree-based models are much less sensitive to scale, which is the tempting exception.
