Sample SnowPro Advanced DE practice questions
5 questions taken from the SnowPro Advanced DE mock tests on Wrexa Edge. Try each one, then reveal the answer.
-
Q1. Why might a secure view perform slower than an equivalent standard view?
- Secure views always bypass the micro-partition metadata
- Secure views force a full Fail-safe read for each query
- Secure views must be refreshed before every single query
- Some optimizations are disabled to avoid exposing hidden data
Show answer
Answer: D — Some optimizations are disabled to avoid exposing hidden data
Secure views skip optimizations that could leak filtered data (such as pushing user predicates ahead of security filters) and hide the view definition.
-
Q2. Files older than the load-metadata window have unknown load status, and COPY skips them. Which option tells COPY to attempt loading them?
- LOAD_UNCERTAIN_FILES = TRUE
- MATCH_BY_COLUMN_NAME = CASE_INSENSITIVE
- ENFORCE_LENGTH = FALSE
- RETURN_FAILED_ONLY = TRUE
Show answer
Answer: A — LOAD_UNCERTAIN_FILES = TRUE
When load status is uncertain (for example, the file's LAST_MODIFIED date is older than 64 days), COPY skips by default; LOAD_UNCERTAIN_FILES = TRUE loads them.
-
Q3. A table was dropped and a new table with the same name was created. UNDROP fails. What should be done?
- Run UNDROP with the FORCE option
- Rename the new table, then run UNDROP
- Increase retention, then run UNDROP
- Clone the schema, then run UNDROP
Show answer
Answer: B — Rename the new table, then run UNDROP
UNDROP fails if an object with the same name already exists; rename or drop the current one first.
-
Q4. A non-admin role owns tasks, but they fail to run. Which account-level privilege must the owner role have?
- MONITOR USAGE
- CREATE ACCOUNT
- EXECUTE TASK
- APPLY MASKING POLICY
Show answer
Answer: C — EXECUTE TASK
The task owner role needs the global EXECUTE TASK privilege (plus EXECUTE MANAGED TASK for serverless tasks) and usage on the objects it references.
-
Q5. Files were staged before an auto-ingest pipe was created. How can they be loaded through the pipe?
- ALTER PIPE ... RESUME, which loads every file ever staged in the bucket
- CREATE PIPE ... CLONE, which copies past events from the queue
- SELECT SYSTEM$PIPE_STATUS, which triggers a backfill automatically
- ALTER PIPE ... REFRESH, which queues files staged in the last 7 days
Show answer
Answer: D — ALTER PIPE ... REFRESH, which queues files staged in the last 7 days
ALTER PIPE REFRESH queues staged files modified within the last 7 days for loading; for older files, use COPY INTO directly.
