Correct answer & explanation
✓
Encrypting data at rest with tenant-specific keys
Hypervisor isolation, storage network segmentation (e.g., VLANs), and data encryption at rest are all valid isolation methods. Shared memory and single database schema for all tenants would break 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.
- ✓
Encrypting data at rest with tenant-specific keys
Why this is correct
Encryption prevents unauthorized access.
- ✗
Using a single database schema for all tenants
Why it's wrong here
That would allow data mixing; not isolated.
- ✓
Storage area network (SAN) zoning to separate tenant data
Why this is correct
Network-level storage isolation.
- ✗
Shared memory segments across tenants for performance
Why it's wrong here
Shared memory would violate isolation.
- ✓
Hypervisor-level isolation between virtual machines
