QUESTION 43
What are two benefits of Virtual Compatibility Mode for RDMs, as compared to Physical Compatibility Mode (Choose Two)?
A.Allows for the use of array-based snapshots
B.Allows the use of SAN-aware applications
C.Allows for template creation of the related virtual machine
D.Allows for cloning
Answer: CD
Explanation:
Storage options for virtual machines: Raw device mappings, VMFS
RDM limitations
There are two types of RDMs: virtual compatibility mode RDMs and physical compatibility mode RDMs. Physical mode RDMs, in particular, have some fairly significant limitations:
No VMware snapshots
No VCB support, because VCB requires VMware snapshots
No cloning VMs that use physical mode RDMs
No converting VMs that use physical mode RDMs into templates
No migrating VMs with physical mode RDMs if the migration involves copying the disk
No VMotion with physical mode RDMs

QUESTION 45
During Guided Consolidation, how is disk space for the virtual machine calculated?
A.The virtual machine disk is equal in size to the source disk
B.The virtual machine disk is sized to the amount of data contained on the source disk
C.The virtual machine disk is sized to 125% of the data contained on the source disk
D.Guided Consolidation prompts for the virtual machine disk size during conversion
Answer: C
Explanation:
vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 95.
The following formula is used to resize converted disks:
amount of space used on physical disk * 1.25 = resultant virtual disk size
Virtual disks are set to a size of 4GB or larger.
QUESTION 46
What is the maximum number of systems guided consolidation can simultaneously analyze?
A.1000
B.500
C.250
D.100
Answer: D
Explanation:
What’s New in VMware vSphere 4.0
Guided Consolidation Enhancements – The Guided Consolidation service is now a modular plug-in to vCenter Server. This service can be installed on a different system than vCenter Server, allowing vCenter Server to perform optimally with lower overheads around consolidation operations. Guided Consolidation is also able to discover and analyze systems that run non-English versions of Windows. Guided Consolidation can concurrently analyze and make consolidation recommendations for up to 100 physical machines at a given time
