During an upgrade, the ESXi 5.x installer finds an existing version of ESXi and a VMFS3 volume. No virtual machines exist on the host or VMFS3 volume. The requirement is to upgrade to VMFS5.
Which option should be chosen to meet this requirement?
A. Upgrade ESXi and preserve the VMFS datastore
B. Install ESXi and preserve the VMFS datastore
C. Install ESXi and overwrite the VMFS datastore
D. Upgrade ESXi and overwrite the VMFS datastore
Correct Answer: C
Explanation/Reference:
Explanation:
To have the benefit of all the VMFS-5 enhancements, it is recommended that you create a new VMFS-5 volume rather than upgrading VMFS-3 to VMFS-5. To accomplish this, you must install ESXi and overwrite the VMFS datastore.
Incorrect Answers:
A, B: Preserving the datastore will retain the VMFS-3 volume, which can then be upgraded. However, to have the benefit of all the VMFS-5 enhancements, it is recommended that you create a new VMFS-5 volume rather than upgrading VMFS-3 to VMFS-5
D: The datastore cannot be overwritten during an upgrade process.
