Data sources & datasets — quiz
10 questions covering this module. Connecting, preparing datasets, SPICE and refresh.
A SPICE refresh suddenly fails across several datasets. First thing to check?
- Chart configuration
- SPICE capacity in the admin console
- Dashboard permissions
- Parameter defaults
Answer: SPICE capacity in the admin console — Exhausted account capacity is the usual cause, often from abandoned datasets.
Which requires a date column?
- Full refresh
- Incremental refresh
- Direct query
- SPICE ingestion
Answer: Incremental refresh — Incremental refresh filters a look-back window, which needs a date field.
Map visuals are not available for your city field. Most likely cause?
- SPICE is full
- No geographic role assigned
- Wrong edition
- Direct query mode
Answer: No geographic role assigned — QuickSight only offers geospatial charts once a geographic role is set on the field.
Where is complex join logic best maintained?
- Custom SQL inside the dataset
- A view in the warehouse
- An analysis-level calculated field
- A dashboard filter
Answer: A view in the warehouse — A warehouse view is version-controlled, reusable and easier to debug than embedded SQL.
Connecting QuickSight to S3 requires:
- A bucket policy only
- A manifest file describing the objects
- A VPC connection
- SPICE capacity
Answer: A manifest file describing the objects — It lists URIs or prefixes and the file format.
A source works in the AWS console but not QuickSight. Likely cause?
- SPICE is full
- QuickSight lacks its own service permissions
- Wrong region
- The dataset is stale
Answer: QuickSight lacks its own service permissions — Grant them in Manage QuickSight → Security & permissions.
A calculation two reports both need belongs in:
- Each analysis
- The dataset
- The dashboard
- A parameter
Answer: The dataset — Shared definitions prevent reports disagreeing.
A numeric ID field is being summed. Fix:
- Change the visual
- Change its role from measure to dimension
- Add a filter
- Refresh SPICE
Answer: Change its role from measure to dimension — Numeric fields default to measures.
A dashboard shows stale data with no error. Check first:
- The visual type
- Whether SPICE capacity was exceeded and the refresh failed
- Parameters
- Permissions
Answer: Whether SPICE capacity was exceeded and the refresh failed — Capacity failures are easy to miss.
Incremental refresh does not capture:
- New rows
- Rows updated or deleted outside the lookback window
- Large tables
- Calculated fields
Answer: Rows updated or deleted outside the lookback window — Hence a periodic full refresh.
