2V0-620 Question #24: Real Exam Question with Answer & Explanation

Question

Options

• AThe new vSphere 6.x cluster is running Intel CPUs instead of AMD CPUs.
• BA suspended virtual machine cannot be migrated.
• CThe hardware virtualization feature of the CPU is not enabled on the new hosts.
• DA vSphere Distributed Switch is required to migrate a suspended virtual machine.

Explanation

Migrating a suspended virtual machine requires CPU compatibility between source and destination hosts; a mismatch in CPU vendor (Intel vs. AMD) makes the saved CPU register state incompatible, causing the vMotion compatibility check to fail.

Common mistakes.

• B. Suspended virtual machines can be migrated using vMotion; vSphere explicitly supports migration of suspended VMs as long as CPU and hardware compatibility requirements between the source and destination hosts are satisfied.
• C. Hardware virtualization extensions (Intel VT-x or AMD-V) being disabled affects the ability to run VMs requiring hardware-assisted virtualization, but the compatibility failure described here is caused by a CPU vendor mismatch between the saved suspended state and the destination host, not by missing virtualization extensions.
• D. A vSphere Distributed Switch is not a requirement for migrating a suspended virtual machine; vMotion can operate over standard vSwitches, and the network switch type is unrelated to the CPU-compatibility failure that causes this check to fail.
