VMware vSphere 6 Foundations (VCP6-DCV) — Question 8

An administrator is attempting to enable Storage I/O Control on a datastore, but it is failing.

What is the likely reason for this failure?

Answer options

• A. The host is connected to a datastore is running on ESX 4.0.
• B. The host is connected to a Fibre Channel storage array.
• C. The datastore has multiple extents.
• D. The datastore is managed by a single vCenter Server.

Correct answer: A

Explanation

The correct answer is A because Storage I/O Control requires a minimum of ESXi 5.0 to function properly, and ESX 4.0 does not support it. The other options do not inherently prevent the enabling of Storage I/O Control, as Fibre Channel arrays, multiple extents, and single vCenter Server management are compatible with the feature.
