Your network contains an Active Directory domain named contoso.com. The domain contains two servers named Server1 and Server2.
Server1 runs Windows Server 2012 R2. Server2 runs Windows Server 2008 R2 Service Pack 1 (SP1) and has the DHCP Server server role installed.
You need to manage DHCP on Server2 by using the DHCP console on Server1.
What should you do first?
A. From Windows Firewall with Advanced Security on Server2, create an inbound rule.
B. From Internet Explorer on Server2, download and install Windows Management Framework 3.0.
C. From Server Manager on Server1, install a feature.
D. From Windows PowerShell on Server2, run Enable PSRemoting.
The Enable-PSRemoting cmdlet configures the computer to receive Windows PowerShell remote commands that are sent by using the WS-Management technology. On Windows Server 2012 R2, Windows PowerShell remoting is enabled by default. You can use Enable-PSRemoting to enable Windows PowerShell remoting on other supported versions of Windows and to re-enable remoting on Windows Server 2012 if it becomes disabled. You need to run this command only once on each computer that will receive commands. You do not need to run it on computers that only send commands. Because the configuration activates listeners, it is prudent to run it only where it is needed.
Note: (not B) You can use Server Manager to manage remote servers that are running Windows Server 2008 and Windows Server 2008 R2, but the following updates are required to fully manage these older operating systems.

Your network contains an Active Directory domain named contoso.com. The domain contains a member server named HVServer1. HVServer1 runs Windows Server 2012 and has the Hyper-V server role installed. HVServer1 hosts 10 virtual machines. All of the virtual machines connect to a virtual switch named Switch1. Switch1 is configured as a private network. All of the virtual machines have the DHCP guard and the router guard settings enabled.
You install the DHCP server role on a virtual machine named Server 1. You authorize Server1 as a DHCP server in contoso.com. You create an IP scope.
You discover that the virtual machines connected to Switch1 do not receive IP settings from Server1.
You need to ensure that the virtual machines can use Server1 as a DHCP server.
What should you do?
A. Enable MAC address spoofing on Server1.
B. Disable the DHCP guard on all of the virtual machines that are DHCP clients.
C. Disable the DHCP guard on Server1.
D. Enable single-root I/O virtualization (SR-IOV) on Server1.
Private virtual networks are used where you want to allow communications between virtual machine to virtual machine on the same physical server In a block diagram, a private network is an internal network without a virtual NIC in the parentpartition. A private network would commonly be used where you need complete isolation of virtual machines from external and parent partition traffic. DMZ workloads running on a leg of a tri-homed firewall, or an isolated test domain are examples where this type of network may be useful.
DHCP Guard is a feature that you can use (as the owner of the hypervisor) to prevent VMs that you do not authorize from acting as DHCP Servers. Unauthorized and Authorized is a procedural / process phrase. It is not a technical phrase or any setting
that can be applied. It is the business decision to call machine authorized or not. DHCP Guard is specific to the port / vNIC of a VM. And the setting moves with the VM / vNIC.
DHCPGuard allows you to specify whether DHCP server messages coming from a VM should be dropped. For VMs that are running an authorized instance of the DHCP server role, you can turn DHCPGuard off by using the following cmdlet:
Set-VMNetworkAdapter – VMName MyDhcpServer1 – DhcpGuard Off
For all other VMs that are not authorized DHCP servers, you can prevent them from becoming a rogue
DHCP server by turning DHCPGuard on, using the following cmdlet.
Set-VMNetworkAdapter – VMName CustomerVM – DhcpGuard On

You work as a senior administrator at L2P.com. The L2P.com network consists of a single domain named L2P.com. All servers on the L2P.com network have Windows Server 2012 R2 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.
You have a server named Server1 that runs a Server Core Installation of Windows Server 2012 R2. You attach a 4-TB disk to Server1. The disk is configured as an MBR disk. You need to ensure that you can create a 4-TB volume on the disk. Which Diskpart command should you use?
You can use Diskpart to convert a basic disk to a dynamic disk. The basic disk can either be empty or containeither primary partitions or logical drives. The basic disk can be a data disk or system or boot drive. A MBR file structure is only capable of 2TB maximum. The disk will have to be converted to a GPT filestructure. GPT is capable of 18 exabytes volumes. Convert gpt – Converts an empty basic disk with the master boot record (MBR) partition style into a basic diskwith the GUID partition table (GPT) partition style. The disk may be a basic or a dynamic disk but it must not contain any valid data partitions or volumes.
Your network contains an Active Directory domain named contoso.com. The domain contains a server named Server1. Server1 runs Windows Server 2012 R2. You need to create 3-TB virtual hard disk (VHD) on Server1. Which tool should you use?
A. Server Manager
New-VirtualDisk – Creates a new virtual disk in the specified storage pool.
Although the new Server Manager UI in Windows Server 2012 R2 provides a very convenient and intuitive workflow to provision and manage Storage, interaction with PowerShell is required to access many of the advanced features.
If I then create a simple 200GB Virtual Disk via the UI named VDiskSimpleUI, the resulting Virtual Disk leverages 8 columns and maintains 1 copy of the data. But when creating the Virtual Disk via PowerShell,
I can force the tripping across all nine of the disks and optimize performance.
New-VirtualDisk -StoragePoolFriendlyName Pool01 – ResiliencySettingName Simple – Size 200GB – FriendlyName VDiskSimplePS – ProvisioningType Fixed – NumberOfDataCopies 1
– NumberOfColumns 9
And creating a mirrored 200GB Virtual Disk via the UI named VDiskMirrorUI produces a Virtual Disk with 4 columns and 2 data copies. But with PowerShell, I can create a slightly different configuration, increasing the data protection (and also the disk footprint):
New-VirtualDisk -StoragePoolFriendlyName Pool01 -ResiliencySettingName Mirror -Size 200GB –
FriendlyName VDiskMirrorPS -ProvisioningType Fixed -NumberOfDataCopies

Your network contains an Active Directory domain named contoso.com. All domain controllers run Windows Server 2012 R2. You create and enforce the default AppLocker executable rules. Users report that they can no longer execute a legacy application installed in the root of drive C. You need to ensure that the users can execute the legacy application. What should you do?
A. Modify the action of the existing rules.
B. Create a new rule.
C. Add an exception to the existing rules.
D. Delete an existing rule.
AppLocker is a feature that advances the functionality of the Software Restriction Policies feature. AppLocker contains new capabilities and extensions that reduce administrative overhead and help administrators control how users can access and use files, such as executable files, scripts, Windows Installer files, and DLLs. By using AppLocker, you can:
Define rules based on file attributes that persist across application updates, such as the publisher name (derived from the digital signature), product name, file name, and file version. You can also create rules based on the file path and hash.
Assign a rule to a security group or an individual user.
Create exceptions to rules. For example, you can create a rule that allows all users to run all Windows binaries except the Registry Editor (Regedit.exe).
Use audit-only mode to deploy the policy and understand its impact before enforcing it. . Create rules on a staging server, test them, export them to your production environment, and then import them into a Group Policy Object.
Simplify creating and managing AppLocker rules by using Windows PowerShell cmdlets for AppLocker.
AppLocker default rules
AppLocker allows you to generate default rules for each of the rule types.
Executable default rule types:
Allow members of the local Administrators group to run all applications. Allow members of the Everyone group to run applications that are located in the Windows folder. Allow members of the Everyone group to run applications that are located in the Program Filesfolder. Windows Installer default rule types:
Allow members of the local Administrators group to run all Windows Installer files. Allow members of the Everyone group to run digitally signed Windows Installer files. Allow members of the Everyone group to run all Windows Installer files located in the Windows\Installer folder. Script default rule types:
Allow members of the local Administrators group to run all scripts. Allow members of the Everyone group to run scripts located in the Program Files folder. Allow members of the Everyone group to run scripts located in the Windows folder. DLL default rule types:( this on can affect system performance ) Allow members of the local Administrators group to run all DLLs. Allow members of the Everyone group to run DLLs located in the Program Files folder. Allow members of the Everyone group to run DLLs located in the Windows folder. You can apply AppLocker rules to individual users or to a group of users. If you apply a rule to a group of users, all users in that group are affected by that rule. If you need to allow a subset of a user group to use an application, you can create a special rule for that subset. For example, the rule “Allow Everyone to run Windows except Registry Editor” allows everyone in the organization to run the Windows operating system, but it does not allow anyone to run Registry Editor.
The effect of this rule would prevent users such as Help Desk personnel from running a program that is necessary for their support tasks. To resolve this problem, create a second rule that applies to the Help Desk user group: “Allow Help Desk to run Registry Editor.” If you create a deny rule that does not allow any users to run Registry Editor, the deny rule will override the second rule that allows the Help Desk user group to run Registry Editor.
You have two servers named Server! and Server2. Both servers run Windows Server 2012 R2. The servers are configured as shown in the following table.
A. Disable Windows Firewall.
B. Modify the default gateway settings.
C. Modify the DNS settings.
D. Modify the subnet mask.
Route is used to view and modify the IP routing table.
Route Print displays a list of current routes that the host knows. Default gateways are important to make IP routing work efficiently. TCP/IP hosts rely on default gateways for most of their communication needs with hosts on remote networksegments. In this way, individual hosts are freed of the burden of having to maintain extensive andcontinuously updated knowledge about individual remote IP network segments. Only the router that acts as thedefault gateway needs to maintain this level of routing knowledge to reach other remote network segments inthe larger internetwork. In order for Host A on Network 1 to communicate with Host B on Network 2, Host A first checks its routing tableto see if a specific route to Host B exists. If there is no specific route to Host B, Host A forwards its TCP/IPtraffic for Host B to its own default gateway, IP Router 1.
Your network contains an Active Directory domain named contoso.com. The domain contains a server named Server1 that runs Windows Server 2012 R2. Server1 has the Hyper- V server role installed. The domain contains a virtual machine named VM1. A developer wants to attach a debugger to VM1. You need to ensure that the developer can connect to VM1 by using a named pipe. Which virtual machine setting should you configure?
A. Network Adapter
D. COM 1
Named pipe. This option connects the virtual serial port to a Windows named pipe on the host operatingsystem or a computer on the network. A named pipe is a portion of memory that can be used by one processto pass information to another process, so that the output of one is the input of the other. The second processcan be local (on the same computer as the first) or remote (on a networked computer). For example, a localnamed pipe path could be \\.\pipe\mypipename. Named pipes can be used to create a virtual null modem cable between two virtual machines, or between avirtual machine and a debugging program on the host operating system that supports the use of named pipes.
By connecting two virtual serial ports to the same named pipe, you can create a virtual null modem cableconnection. Named pipes are useful for debugging or for any program that requires a null modem connection.
