CCSP Cloud Concepts, Architecture, and Design Practice Question
A cloud security architect is designing a multi-tenant SaaS application. Which TWO isolation mechanisms should be implemented to prevent data leakage between tenants?
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
✓
Network isolation using virtual networks
Network isolation (e.g., VLANs, VPCs) and storage isolation (e.g., separate databases or encryption per tenant) are key. Data encryption at rest protects data but not isolation between tenants. Identity federation and API rate limiting are not isolation mechanisms.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
API rate limiting
Why it's wrong here
Rate limiting controls usage, not isolation.
- ✓
Network isolation using virtual networks
Why this is correct
Network isolation prevents unauthorized access between tenants.
- ✓
Storage isolation through separate databases or schemas
Why this is correct
Storage isolation ensures tenant data is logically separated.
- ✗
Data encryption at rest
Why it's wrong here
Encryption protects data if accessed, but does not isolate tenants.
- ✗
Identity federation
Why it's wrong here
Identity federation is for authentication, not isolation.
