In an IaaS model, to which of the following methodologies would the client apply a list of OS patches, assuming approval from CAB has been given?
A. Using a patch management system, identify the hypervisor type, select a group of hypervisors to be
patched, and perform a rolling application of patches.
B. Using a patch management system, identify the guests that require patching, and select and apply the patches.
C. Using a patch management system, identify the applications needing the patch, select
the required application in a patch management console, and apply the patches.
D. Using a patch management system, identify the services that require patching, and select and apply the patches.
Answer must be B since hypervisor patches are handled by Cloud vendor for IaaS.

Hmm, in an IaaS model you wouldn’t need CAB permission to patch guest OS’. The question seems ambiguous but hinges on the “assuming approval from CAB has been given?” statement. Assuming the infrastructure is just a bare metal resource.

Yeah, should be B, as IaaS traditionally includes the underlying HyperVisor layer.
