CCSP Cloud Concepts, Architecture, and Design Practice Question
A cloud security architect is designing a multi-tenant SaaS application that must ensure strong isolation between tenants. Which TWO mechanisms are most effective for achieving multitenancy isolation?
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
✓
Hypervisor-based virtual machine isolation
Network micro-segmentation and hypervisor-level isolation are key for multi-tenant isolation. Encryption at rest protects data but does not isolate compute; database row-level permissions provide logical but not strong isolation; API rate limiting controls usage but not isolation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Hypervisor-based virtual machine isolation
Why this is correct
Hypervisor isolation separates VMs of different tenants.
- ✓
Network micro-segmentation
Why this is correct
Micro-segmentation isolates network traffic between tenants.
- ✗
Encryption at rest for all tenant data
Why it's wrong here
Encryption protects data but does not isolate compute or network.
- ✗
Database row-level permissions
Why it's wrong here
Logical isolation is weaker than hypervisor or network isolation.
- ✗
API rate limiting per tenant
Why it's wrong here
Rate limiting controls usage, not isolation.
