If a virtual machine on a physical host fails, it will not affect other virtual machines on the physical host. Which feature of virtualization technology does this belong to?

Question

Options

• Ato be independent
• BZoning
• Cto isolate
• DEncapsulation

• A

• B
  3% (1)
• C

• D

Explanation

Isolation is the correct answer because virtualization technology creates separate, self-contained environments for each VM, ensuring that a crash, failure, or security breach in one VM cannot propagate to neighboring VMs on the same physical host - they are shielded from each other's faults.

Why the distractors are wrong:

• A (Independence) refers to a VM's ability to operate without relying on another VM, which is a related concept but doesn't specifically describe the protection barrier that prevents failures from spreading.
• B (Zoning) is a storage/networking term (e.g., SAN zoning) used to segment access, not a core virtualization feature describing VM fault containment.
• D (Encapsulation) describes packaging a VM's entire state (OS, apps, config) into portable files - it's about portability and portability, not fault containment between VMs.

Memory tip: Think of each VM as a fish in its own separate tank. If one fish gets sick, the disease stays in that tank - the other tanks are isolated from it. Isolation = containment of failures.
