A benefit of _______ is if one virtual-instance crashes, it doesn't affect the other virtual machines.

A benefit of _______ is if one virtual-instance crashes, it doesn't affect the other virtual machines.

• A. Isolation
• B. Performance
• C. Redundancy
• D. Transparency

Answer: (A)

Isolation between virtual machines is the idea here. In virtualization, each VM runs in its own sandbox with separate memory, CPU state, and I/O paths managed by the hypervisor. That separation keeps faults contained so a crash in one VM doesn’t spill over to others. The system can halt the failing VM and reallocate its resources without interrupting the rest of the VMs, providing fault containment and security between them. Other terms describe different benefits: performance is about how resources are shared and how fast things run, not about preventing cross-VM impact; redundancy is about having duplicate systems to improve availability, which helps if a component fails but doesn’t inherently stop a crash from affecting others; transparency is about hiding internal details from users, not about isolating faults.
