ARA-C01 Snowflake Architecture Practice Question
An enterprise is designing a multi-tenant SaaS application on Snowflake. Each customer tenant must have completely isolated data storage while allowing the software vendor to query aggregated metrics globally across all tenants without copying data. Which architectural design pattern best satisfies this requirement?
⚠ Common exam trap
Candidates frequently suggest using separate Snowflake accounts for each tenant. While this provides isolation, it creates massive management overhead and makes global cross-tenant analytics significantly more complex and costly to implement.
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
✓
Provision a dedicated database for each tenant within a shared Snowflake account, and use cross-database queries or secure views in a central database for global analytics.
Utilizing separate databases for each tenant provides strict physical isolation and security controls for tenant-specific tables and views. Secure shares or direct cross-database access via a central administrative account allows the vendor to build unified analytics models. This pattern maintains granular access boundaries while avoiding data duplication overhead across cloud regions.
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 a single database with a shared table schema where rows are isolated exclusively by a tenant_id column enforced via row-level security policies.
Why it's wrong here
Row-level security policies provide logical data segregation within a single table, but enterprise tenants often demand physical isolation across separate databases to comply with strict regulatory frameworks and mitigate the risk of accidental cross-tenant data exposure.
- ✗
Deploy a separate Snowflake account for each customer tenant and use data sharing to pipe all tenant data into a central analytical account for global reporting.
Why it's wrong here
Deploying completely separate accounts introduces significant administrative overhead for provisioning, user management, and metadata synchronization. A single account with isolated databases simplifies operational governance while achieving the desired multi-tenant architecture.
- ✓
Provision a dedicated database for each tenant within a shared Snowflake account, and use cross-database queries or secure views in a central database for global analytics.
Why this is correct
Dedicated per-tenant databases give each customer physically separate storage, meeting the isolation constraint, while cross-database queries and secure views let the vendor read aggregated metrics across all tenants from one account without replicating or copying data.
- ✗
Store all tenant data inside separate AWS S3 buckets and ingest them into temporary tables on-demand whenever the vendor requires global analytical reporting.
Why it's wrong here
Ingesting S3 data into temporary tables copies tenant data, violating the no-copy requirement, and adds latency. External S3 staging is tempting for bulk loading or one-off analytics, and would suit scenarios where periodic batch ingestion into Snowflake is acceptable.
