DP-420 sample questions

2 questions from the DP-420 practice set, with the answer and explanation.

  1. Question 1
    A product catalog is read mostly by productId and is also filtered by category. Which partition key gives the best distribution for most point reads and queries?
    • A.
      /productId
    • B.
      /isActive
    • C.
      /warehouseRegion
    • D.
      /category
    Show answer

    Correct answer:

    • A.
      /productId

    Explanation

    A high-cardinality property that most reads supply spreads items across logical and physical partitions and avoids hot spots. Two-value and three-value keys concentrate data into very few logical partitions, which hits the 20 GB logical partition limit and causes throttling. The category option is tempting because it looks natural for browsing, but its small value set produces uneven load.
  2. Question 2
    Strong consistency can be used on an account that has multiple write regions enabled.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • B.
      False

    Explanation

    Strong consistency is not supported when an account is configured for multi-region writes, because it cannot give a single linearizable order across regions without blocking writes. Strong is limited to single-write-region accounts. The statement is therefore false.
