CompTIA 220-1201 Practice Test 23
Question 220
At Orchard Services, a technician working in IT virtualization planning identifies this issue: A new virtual machine cannot start a 64-bit guest even though the host processor supports virtualization. The supporting record states that firmware currently disables the processor's VT-x or AMD-V virtualization feature. The desired outcome is to identify firmware virtualization prerequisites for a supported VM platform. A safe non-destructive test must be used before replacing additional parts. What observation would verify successful service restoration?
- Verify work executes on the hosted desktop and user policy is enforced centrally
- Verify the 64-bit guest starts normally without host instability
- Confirm the VM can be isolated and removed without reinstalling the laptop host
- Verify the application runs in its container while kernel version comes from the host
Explanation
Correct Answer
B:
Verify the 64-bit guest starts normally without host instability. It proves the required function with an observable result instead of assuming the change worked. The relevant observation is that firmware currently disables the processor's VT-x or AMD-V virtualization feature. The support goal is to identify firmware virtualization prerequisites for a supported VM platform; this validate action specifically addresses virtualization cpu extensions without confusing a different subsystem.
