• Question 20:

  Which of the following is the hypervisor for VMware?

  A. vSphere

  B. vCenter

  C. vCloud Director

  D. ESXi

  Correct Answer: A

  Reference https://www.vmware.com/products/vsphere-hypervisor.html Note: Technically there are two answers to this question. Both vSphere and ESXi are hypervisors for VMware. The only difference is ESXi is a bare-metal enterprise class hypervisor. However, the question is generic therefore, both AD are correct answers.
