PDE Maintaining and Automating Data Workloads Practice Question

You have a BigQuery table that is used by multiple teams. To save costs, you want to provide a consistent view of the data as of a specific point in time without creating full copies. Which BigQuery feature should you use?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Table snapshot

BigQuery table snapshots provide a point-in-time copy of a table that incurs only storage costs for the snapshot (no additional slot usage). They are read-only and can be used to share data without duplicating the base table.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Authorized views

    Why it's wrong here

    Authorized views provide controlled access but always reflect the current data, not a point-in-time.

  • ✗

    Materialized views

    Why it's wrong here

    Materialized views are automatically refreshed and not point-in-time.

  • ✓

    Table snapshot

    Why this is correct

    Table snapshots are read-only, point-in-time copies that cost only storage and are ideal for sharing consistent views.

  • ✗

    Table clone

    Why it's wrong here

    Table clones are writable copies that share storage with the base table until modified, but they are not point-in-time consistent snapshots.
