  9. Question 8 of 10

    A candidate has limited study time and is equally weak in Data Transformation and Modeling, Data Ingestion and Loading, and Databricks Intelligence Platform. Which ordering best follows the published weights?

    1. AIngestion and Loading, then Intelligence Platform, then Transformation and Modeling
    2. BIntelligence Platform, then Ingestion and Loading, then Transformation and Modeling

  10. Question 9 of 10

    During the proctored assessment, a candidate sees an unusually experimental-looking item and cannot identify whether it is scored. The time limit still applies. What is the sound response?

    1. AOpen the exam guide to verify its status because test aides are permitted
    2. BSkip it automatically because experimental-looking items never affect the score
    3. CWait for the proctor to label it because unscored items are identified on screen
    4. DTreat it as a live item and manage time because unscored items are unidentified
    Show the answer

    Unscored content may appear without identification and does not affect the score, so appearance cannot justify ignoring an item.

    2. BRegistration is blocked until a professional certification verifies the learner's experience
    3. CRegistration is allowed, but hands-on practice is still the recommended preparation
    4. DRegistration is allowed only if the learner chooses online rather than test-center delivery
