Sample Questions — Snowflake SnowPro Advanced: Architect (ARA-C01)

5 free sample questions from this practice exam. Correct answers are highlighted.

1. A company is deploying Snowflake for the first time and wants to ensure that development, test, and production workloads are completely isolated from each other, including compute resources, data access, and billing. What is the recommended architectural approach?

A Create separate Snowflake accounts for development, test, and production environments ✓ Correct
B Create separate databases within a single Snowflake account for each environment
C Create separate virtual warehouses within a single account, one per environment
D Use resource monitors at the database level to cap spending per environment

2. A healthcare company stores Protected Health Information (PHI) in Snowflake and must comply with HIPAA. The security team wants to ensure that data analysts can query patient records but see only masked SSNs, while the compliance team sees full SSNs. Which Snowflake feature combination achieves this requirement with the least administrative overhead?

A Create a Dynamic Data Masking policy on the SSN column that returns the full value when CURRENT_ROLE() = 'COMPLIANCE_ROLE' and a masked value otherwise, then apply it to the column. ✓ Correct
B Create two separate tables — one with masked SSNs for analysts and one with full SSNs for compliance — and grant SELECT privileges accordingly.
C Apply a Row Access Policy to the patient table that filters rows based on the querying role, limiting analysts to a subset of records.
D Create two secure views on the patient table — one with MASK(SSN) for analysts and one with the raw SSN for compliance — and grant each role access to its respective view.

3. An architect is evaluating whether to use IdP-initiated or SP-initiated SAML 2.0 SSO for Snowflake. The security team requires the highest level of protection against SAML assertion replay attacks. Which initiation method provides better protection and why?

A IdP-initiated SSO provides better protection because the IdP controls assertion generation and can implement its own replay prevention mechanisms
B Both methods provide equal protection against replay attacks because both rely on assertion expiration timestamps (NotOnOrAfter)
C SP-initiated SSO provides better protection because Snowflake generates a unique request ID that the IdP must reference in InResponseTo, allowing replay detection ✓ Correct
D Neither method prevents replay attacks; protection requires configuring mutual TLS between Snowflake and the IdP

4. A data architect is designing a star schema in Snowflake for a retail analytics workload. The fact table has 500 million rows and several dimension tables range from 10,000 to 5 million rows. Which Snowflake-specific design recommendation should the architect follow to maximize query performance?

A Keep dimensions denormalized in a flat star schema; avoid normalizing into a snowflake schema to reduce join complexity ✓ Correct
B Add a clustering key to every dimension table to improve join performance with the fact table
C Store all dimension tables as transient tables to reduce Time Travel storage costs
D Create materialized views over all dimension tables to pre-compute join results

5. A company requires a Snowflake disaster recovery design where the production account must be restored within 4 hours of a regional failure. Which Snowflake feature directly supports achieving this Recovery Time Objective (RTO)?

A Configure Failover Groups between a primary and a secondary account in different cloud regions ✓ Correct
B Set Time Travel retention to 90 days on all critical tables
C Rely on Snowflake Fail-safe to recover data within the 7-day window
D Enable database replication to a secondary account without configuring Failover Groups
