CV0-004 Practice Question: A cloud administrator is designing a secure…
A cloud administrator is designing a secure multi-tenant environment. Which THREE of the following are best practices for isolating tenant workloads?
⚠ Common exam trap
CompTIA often tests the misconception that a single virtual switch can be securely partitioned using VLANs alone, but the trap is that VLANs only provide Layer 2 isolation and do not protect against misconfigurations or attacks within the shared virtual switch control plane.
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
✓
Deploy tenant workloads on dedicated hypervisors.
Deploying tenant workloads on dedicated hypervisors provides strong physical isolation, preventing a compromised hypervisor from affecting other tenants. This approach eliminates the risk of side-channel attacks or resource contention that could cross tenant boundaries, ensuring each tenant's virtual machines run on separate hardware with no shared compute resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a single virtual switch for all tenants.
Why it's wrong here
A shared vSwitch can allow sniffing.
- ✓
Deploy tenant workloads on dedicated hypervisors.
Why this is correct
Dedicated hypervisors prevent hypervisor-level attacks.
- ✓
Implement micro-segmentation using virtual firewalls.
Why this is correct
Micro-segmentation limits east-west traffic.
- ✓
Use separate VLANs for each tenant.
Why this is correct
VLANs provide Layer 2 isolation.
- ✗
Place all tenants on the same storage array for efficiency.
Why it's wrong here
Shared storage can lead to data leakage.
