Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create external schema in Redshift, then create external table, then grant permissions, then run the query, then verify results.
Why this is correct
This is the correct order because you must first define the schema to reference the external data catalog, then create the table within that schema, grant necessary permissions to the querying user, execute the query, and finally confirm the output.
- ✗
Run the query, then verify results, then create external table, then grant permissions, then create external schema.
Why it's wrong here
This is incorrect because you cannot run a query without first having the schema and table defined and permissions granted. The order is completely reversed.
- ✗
Create external table, then create external schema, then grant permissions, then run the query, then verify results.
Why it's wrong here
This is incorrect because you must create the external schema before creating the external table; the table belongs to a schema.
- ✗
Create external schema, then create external table, then run the query, then grant permissions, then verify results.
Why it's wrong here
This is incorrect because you must grant permissions on the schema and table before running the query; otherwise, the query will fail due to lack of access.
