Answer: A,C 

Explanation: 

NUMA is a hardware design feature that divides CPUs and memory in a physical server into NUMA nodes. You get the best performance when a process uses memory and CPU from within the same NUMA node. de is full, then it’ll get memory from When a process requires more memory, but the current NUMA no another NUMA node and that comes at a performance cost to that process, and possibly all other processes on that physical server. And that’s why virtualization engineers need to be aware of this. In Hyper-V we have Dynamic Memory. Non-Uniform Memory Access or Non-Uniform Memory Architecture (NUMA) is a computer memory design used in multiprocessors, where the memory access time depends on the memory location relative to a processor. Under ccNUMA, a processor can access its own local memory faster than non-local memory, that is, memory local to another processor or memory shared between processors. NUMA architectures logically follow in scaling from symmetric multiprocessing (SMP) architectures.

Explanation: 

If you enable Shadow Copies of Shared Folders on a volume using the default values, a task will be scheduled to create shadow copies at 7:00 A.M of next business day. The default storage area will be on the same volume, and its size will be 10 percent of the available space. You can only enable Shadow Copies of Shared Folders on a per-volume basis–that is, you cannot select specific shared folders and files on a volume to be copied or not copied. 

To enable and configure Shadow Copies of Shared Folders: 

1. Click Start, point to Administrative Tools, and then click Computer Management. 

2. In the console tree, right-click Shared Folders, click All Tasks, and then click Configure Shadow Copies. 

3. In Select a volume, click the volume that you want to enable Shadow Copies of Shared Folders for, and then click Enable. 

4. You will see an alert that Windows will create a shadow copy now with the current settings and that the settings might not be appropriate for servers with high I/O loads. Click Yes if you want to continue or No if you want to select a different volume or settings. 

5. To make changes to the default schedule and storage area, click Settings. 

Shadow copies - a feature that provides point-in-time copies of files stored on file shares on file servers. Shadow Copies of Shared Folders allows users to view and access shadow copies, which are shared files and folders as they existed at different points of time in the past. By accessing previous versions of files and folders, users can compare versions of a file while working and recover files that were accidentally deleted or overwritten.

Answer: C 

Explanation: 

Since a member server does not have Active Directory Domain Services installed, you must install this role before you can configure the new Domain Controller (which would require you to run Install-ADDSForest).

Answer: C 

Answer: B,D 

Explanation: 

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.

Answer: F 

Explanation: 

Set-ADAccountControl Enabled Specifies if an account is enabled. An enabled account requires a password. This parameter sets the Enabled property for an account object. This parameter also sets the ADS_UF_ACCOUNTDISABLE flag of the Active Directory User Account Control (UAC) attribute. Possible values for this parameter include: $false or 0 $true or 1 The following example shows how to set this parameter to enable the account. -Enabled $true 

Answer: C 

Explanation: 

Changing between a fixed and dynamic disk type does not alter the size of a SNAPSHOT much at all. However, since a snapshot is a record of a VMs state at the exact time that the snapshot was taken, shutting down the VM before taking the snapshot prevents the snapshot from having to contain all of the data in RAM (as there is no data in memory when a machine is powered down). 

The question states that the solution should minimize the amount of disk space used for the checkpoint of VM1. If the checkpoint is taken while VM1 is running, there will be two attritional files present at the checkpoint location; a .VSV with VM1 saved state files and a .BIN file which contains VM1’s memory contents. If, however, VM1 is shut down first, these files will not be created, thus saving disk space. In order to convert Disk1.vhd to a dynamically expanding disk, VM1 still have to be shut down.
