You are reviewing a deployment plan for a multi-tenant database. To ensure security, you want to ensure that each tenant's data is logically isolated. Which strategy is most effective for this?
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
✓
Using separate schemas for each tenant
Implementing separate schemas for each tenant provides a logical separation that allows for efficient management while keeping data isolated within the same instance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using a shared table with a TenantID column
Why it's wrong here
While common, this is less secure than schema isolation because it relies on code-level filtering.
- ✗
Creating separate database instances for every tenant
Why it's wrong here
This is often too resource-intensive and expensive for many multi-tenant scenarios.
- ✗
Implementing row-level security on all tables
Why it's wrong here
RLS is a valid secondary control, but schema-level isolation is a more fundamental architectural choice for multi-tenancy.
- ✓
Using separate schemas for each tenant
Why this is correct
Schema isolation provides a robust logical boundary between tenant datasets.
