You work as a senior administrator at ABC.com. The ABC.com network consists of a single
domain named ABC.com. All servers on the ABC.com network have Windows Server 2012
installed.
You are running a training exercise for junior administrators. You are currently discussing the new
VHD format called VHDX.
Which of the following is TRUE with regards to VHDX? (Choose all that apply.)
A.
It supports virtual hard disk storage capacity of up to 64 GB.
B.
It supports virtual hard disk storage capacity of up to 64 TB.
C.
It does not provide protection against data corruption during power failures.
D.
It has the ability to store custom metadata about the file that the user might want to record.
The main new features of the VHDX format are:
Support for virtual hard disk storage capacity of up to 64 TB.
Protection against data corruption during power failures by logging updates to the VHDX metadata structures.
Improved alignment of the virtual hard disk format to work well on large sector disks.
The VHDX format also provides the following features:
Larger block sizes for dynamic and differencing disks, which allows these disks to attune to the needs of the workload.
A 4-KB logical sector virtual disk that allows for increased performance when used by applications and workloads that are designed for 4-KB sectors.
The ability to store custom metadata about the file that the user might want to record, such as operating system version or patches applied.
Efficiency in representing data (also known as “trim”), which results in smaller file size and allows the underlying physical storage device to reclaim unused space. (Trim requires physical disks directly attached to a virtual machine or SCSI disks, and trim-compatible hardware.)
VHDX Format – Features and Benefits
VHDX format features provide features at the virtual hard disk as well as virtual hard disk file layers and is optimized to work well with modern storage hardware configurations and capabilities.
At the virtual hard disk layer, benefits include the ability to represent a large virtual disk size up to 64 TB, support larger logical sector sizes for a virtual disk up to 4 KB that facilitates the conversion of 4 KB sector physical disks to virtual disks, and support large block sizes for a virtual disk up to 256 MB that enables tuning block size to match the IO patterns of the application or system for optimal performance.
At the virtual hard disk file layer, the benefits include the use of a log to ensure resiliency of the VHDX file to corruptions from system power failure events and a mechanism that allows for small pieces of user generated data to be transported along with the VHDX file.
On modern storage platforms, the benefits include optimal performance on host disks that have physical sector sizes larger than 512 bytes through improved data alignment and capability to use the information from the UNMAP command, sent by the application or system using the virtual hard disk, to optimize the size of the
VHDX file.
The format is designed so that additional features could be introduced in the future by Microsoft or extended by other parser implementations. The format provides parsers the ability to detect features in a VHDX file that a parser does not understand.

I think this dump is very good for the people who do not have much time for their Microsoft 70-410 exam preparation. You can easily pass the exam only by memorize Lead2pass exam questions. Believe or not, I did so and I passed my 70-410 exam:
QUESTION 41
Your network contains a server named Server1 that runs Windows Server 2012 R2. Server1 has the Hyper-V server role installed. Server1 hosts four virtual machines named VM1, VM2, VM3, and VM4. Server1 is configured as shown in the following table.
You install Windows Server 2012 R2 on VM2 by using Windows Deployment Services (WDS).
You need to ensure that the next time VM2 restarts, you can connect to the WDS server by using PXE.
Which virtual machine setting should you configure for VM2?
A. NUMA topology
B. Resource control
C. Resource metering
D. Virtual Machine Chimney
E. The VLAN ID
F. Processor Compatibility
G. The startup order
H. Automatic Start Action
I. Integration Services
J. Port mirroring
K. Single-root I/O virtualization
Answer: G
QUESTION 42
Your network contains an Active Directory domain named contoso.com. The domain contains two domain controllers. The domain controllers are configured as shown in the following table.

C. Open the %windir%\system32\dns\backup\adatum.com.dns file.
D. Run ipconfig /displaydns.
Answer: A
QUESTION 44
Your network contains an Active Directory forest that contains three domains. A group named Group1 is configured as a domain local distribution group in the forest root domain.
You plan to grant Group1 read-only access to a shared folder named Share1. Share1 is located in a child domain.
You need to ensure that the members of Group1 can access Share1.
What should you do first?
A. Convert Group1 to a global distribution group.
B. Convert Group1 to a universal security group.
C. Convert Group1 to a universal distribution group.
D. Convert Group1 to a domain local security group
Answer: B
QUESTION 45
Your network contains an Active Directory domain named contoso.com. All domain controllers run Windows Server 2008 R2. One of the domain controllers is named DCI. The network contains a member server named Server1 that runs Windows Server 2012 R2.
