CCSP Cloud Platform and Infrastructure Security Practice Question
A cloud security architect is designing a multi-tenant virtualized environment. Which type of hypervisor is considered most secure for cloud deployments due to its reduced attack surface and direct hardware control?
⚠ Common exam trap
The trap is assuming that containers or Type 2 hypervisors provide equivalent security to Type 1 hypervisors, when the additional layers or shared kernel increase risk.
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
✓
Type 1 bare-metal hypervisor
A Type 1 bare-metal hypervisor runs directly on the host's hardware, controlling hardware resources and managing guest VMs without an underlying operating system. This architecture reduces the attack surface because there is no general-purpose OS to exploit, and it provides direct hardware control for performance and security. It is considered the most secure for cloud deployments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Type 1 bare-metal hypervisor
Why this is correct
A Type 1 hypervisor runs directly on the host hardware, so it exposes no underlying general-purpose OS for a guest escape to target. That smaller attack surface, plus direct hardware control, satisfies the multi-tenant isolation requirement where a compromised tenant must not reach others or the platform.
- ✗
Type 2 hosted hypervisor
Why it's wrong here
A Type 2 hypervisor runs atop a general-purpose host OS, so the OS kernel sits in the privileged path and widens the attack surface. It is tempting because Type 2 is convenient for developer workstations and desktop virtualisation, where running a guest alongside everyday applications matters more than hardened multi-tenant isolation.
- ✗
Emulated hypervisor (e.g., QEMU without KVM)
Why it's wrong here
QEMU without KVM performs full binary translation in user space, so every privileged instruction is emulated, enlarging the attack surface and removing direct hardware control. It suits running foreign-architecture guests. A Type 1 bare-metal hypervisor, such as Microsoft Hyper-V, runs directly on hardware with a minimal trusted layer.
- ✗
Container runtime (e.g., Docker)
Why it's wrong here
Containers share the host kernel, so a kernel exploit escapes to other tenants; there is no hypervisor layer mediating hardware access. It is tempting because containers are lightweight and fast to provision, and would be correct for packaging trusted, single-tenant microservices where isolation between untrusted tenants is not required.
