QUESTION 99
Your network contains an Active Directory domain named contoso.com. An organizational unit (OU) named OU1 contains user accounts and computer accounts. A Group Policy object (GPO) named GP1 is linked to the domain. GP1 contains Computer Configuration settings and User Configuration settings.
You need to prevent the User Configuration settings in GP1 from being applied to users.
The solution must ensure that the Computer Configuration settings in GP1 are applied to all client computers.
What should you configure?
A. the Group Policy loopback processing mode
B. the Block Inheritance feature
C. the Enforced setting
D. the GPO Status
Answer: A
Explanation:
A. Group Policy loopback with replace option needs to be used
B. Blocking inheritance prevents Group Policy objects (GPOs) that are linked to higher sites, domains, ororganizational units from being automatically inherited by the child-level
C. Enforced prevent blocking at lower level
D. The GPO Status. This indicates whether either the user configuration or computer configuration of the GPOis enabled or disabled.
You can use the Group Policy loopback feature to Apply Group Policy Objects (GPOs) that depend only onwhich computer the user logs on to.
User Group Policy loopback processing can be enabled in one of two modes: merge or replace. In mergemode, both GPOs Applying to the user account and GPOs Applying to the computer account are processedwhen a user logs in. GPOs that Apply to the computer account are processed second and therefore takeprecedence – if a setting is defined in both the GPO(s) Applying to the user account, and the GPO(s) Applyingto the computer account, the setting in the GPO(s) Applying to the computer account will be enforced. With thereplace mode, GPOs Applying to the user account are not processed only the GPOs Applying to thecomputer account are Applied. Loopback can be set to Not Configured, Enabled, or Disabled. In the Enabled state, loopback can be set toMerge or Replace. In either case the user only receives user-related policy settings. Loopback with Replace–In the case of Loopback with Replace, the GPO list for the user is replaced in itsentirety by the GPO list that is already obtained for the computer at computer startup (during step 2 in GroupPolicy processing and precedence). The User Configuration settings from this list are Applied to the user.
Loopback with Merge–In the case of Loopback with Merge, the Group Policy object list is a concatenation.
The default list of GPOs for the user object is obtained, as normal, but then the list of GPOs for the computer(obtained during computer startup) is appended to this list. Because the computer’s GPOs are processed afterthe user’s GPOs, they have precedence if any of the settings conflict. This is a COMPUTER setting, which is found under Computer Configuration | Administrative Templates |
System | Group Policy | User Group Policy Loopback Processing Mode You want to create a new OU in AD that is dedicated to computer accounts that will have loopbackprocessing enabled. Create a new GPO in your new OU to enable User Group Policy Loopback Processing and set theappropriate mode (merge / replace).
You will define the user settings you want to Apply to the loopback-enabled PCs via GPOs in this same newOU.
You can define these settings either in the same GPO where you enabled the User Group PolicyLoopback Processing setting, or you create another new GPO in the same OU for your user settings.
Remember that when using the REPLACE mode, none of your other user GPOs will be Applied whena user logs in to a machine that has loopback processing enabled.
ONLY the user settings that aredefined in the GPOs that Apply to that machine will be Applied.

QUESTION 100
Your network contains two Hyper-V hosts named Host1 and Host2. Host1 contains a virtual machine named VM1.
Host2 contains a virtual machine named VM2. VM1 and VM2 run Windows Server 2012 R2.
You install the Network Load Balancing feature on VM1 and VM2.
You need to ensure that the virtual machines are configured to support Network Load Balancing (NLB).
Which virtual machine settings should you configure on VM1 and VM2?
A. Router guard
B. DHCP guard
C. Port mirroring
D. MAC address
Answer: D
Explanation:
In Hyper-V, the VM host prevents dynamic MAC address updates as an extra layer of security in thedatacenter. This is because the VM may have full administrator rights, yet it may be untrusted in thedatacenter, for example when the VM hosting is provided by an independent hosting company. In this scenario,we need to make sure that one VM cannot cause a DOS or information disclosure attack against another VM. If a VM is able to spoof its MAC address, then it can spoof the MAC addresses of other VMs and impactother VMs on that host. The physical switches have similar protections and it is up to the admin to enable thatprotection or not. If you do not enable spoofing of MAC address prior to configuring NLB on the VM you could potentially haveproblems with the NLB cluster.
When configuring NLB in unicast mode on Hyper-V with enable spoofing of MAC Address disabled you maysee some of the following symptoms:
When initially configuring NLB you will lose network connectivity on the network adaptor NLB was configuredon.
There will be an NLB error event in the Windows Event Log stating that the network adaptor does not supportdynamic MAC address updates.
After rebooting the server, NLB will appear to be bound to the network adapter, but the cluster VIP will nothave been added to the network adaptor.
The cluster MAC address will still be the original MAC address associated with the network adaptor prior toconfiguring NLB. Use CMD>ipconfig /all to view the MAC address.
It should start with “02-BF-***”
If you ignore all previous symptoms and manually add the VIP you could get an IP conflict if there are othernodes in the cluster that have the same VIP.
With that said, to allow VM guests to run NLB you need to set the VM property for “Enable spoofing of MACAddress”.
To enable spoofing of MAC Addresses open the Hyper-V management console. Make sure the VM is stoppedopen the properties of the VM. Select the Network Adaptor for the NLB VM and check the “Enable spoofing ofMAC Address” and click OK. Then start the VM.

D. imagex /Apply Applies image to drive
The Deployment Image Servicing and Management (DISM) tool is a command-line tool that is used to modifyWindows images.
You can use DISM to enable or disable Windows features directly from the commandprompt, or by Applying an answer file to the image.
You can enable or disable Windows features offline on a WIM or VHD file, or online on a running operating system.
You can also use the DISM image management command to list the image index numbers or to verify thearchitecture for the image that you are mounting.ex:
Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:”Base Windows Image”
/MountDir:C:\test\offline
By default, DISM is installed at C:\Program Files (x86)\Windows Kits\8.0\Assessment and

QUESTION 103
Your network contains an Active Directory domain named contoso.com. The network contains a domain controller named DC1 that has the DNS Server server role installed.
DC1 has a standard primary DNS zone for contoso.com.
You need to ensure that only client computers in the contoso.com domain will be able to add their records to the contoso.com zone.
What should you do first?
A. Modify the Security settings of Dc1
B. Modify the Security settings of the contoso.com zone.
C. Store the contoso.com zone in Active Directory
D. Sign the contoso.com zone.
Answer: C
Explanation:
C. Only Authenticated users can create records when zone is stored in AD Secure dynamic updates allow an administrator to control what computers update what names and preventunauthorized computers from overwriting existing names in DNS. If you have an Active Directory infrastructure, you can only use Active Directory – integrated zones on ActiveDirectory domain controllers. If you are using Active Directory – integrated zones, you must decide whether or not to store Active Directory – integrated zones in the Application directory partition.
To configure computers to update DNS data more securely, store DNS zones in Active Directory DomainServices (AD DS) and use the secure dynamic update feature. Secure dynamic update restricts DNS zone updates to only those computers that are authenticated and joinedto the Active Directory domain where the DNS server is located and to the specific security settings that
aredefined in the access control lists (ACLs) for the DNS zone.

K. Single-root I/O virtualization
Answer: I
Explanation:
What is the Hyper-V Saved State?
Some Hyper-V virtual machines briefly go offline into a “Saved State” at the initial phase of a backup.
While the backup is running, they usually come back online after a couple of seconds. Background KnowledgeThe decision to pull Hyper-V virtual machines offline into a Saved State is done solely within Hyper-VManagement Services.
Backup software utilities have no way to force a live backup when Hyper-V determines it can’t and shouldn’t bedone.There are many factors that are considered by Hyper-V when it decides whether to take a VM offline or not,Hyper-V Live Backup Requirements:
To achieve zero downtime live backups of virtual machines, you need the following conditions met:
1. The VM guest needs to have Integration Services installed, enabled, and running (COM+ System Application Service, Distributed Transaction Coordinator Service, and Volume Shadow Copy Service). Alsoreview the VM settings in Hyper-V, the ‘backup’ option needs to be checked.
2. All disks involved need to be formatted with NTFS, including the disks within the VM.
3. The Volume Shadow Copy Service and related VSS services need to be enabled and running.
4. The shadow copy storage space for each drive must be available to Hyper-V VSS Writer and be located atthe same volume. For instance, the storage space for drive C: needs to be on drive C: itself, and so on. Usethe VSSADMIN command from the command line to check the settings. (Use:
vssadmin list shadowstorage /vssadmin resize shadowstorage)
5. Ensure the VMs are partitioned using ‘basic disk’ formatting.
At the moment Hyper-V does not support livebackup for VMs formatted using dynamic disk partitioning or GPT.
7. Ensure you have at least about 20% free space on each drive involved, such as the drive on the host andthe VM’s main system drive.
8. Ensure plenty of un-fragmented RAM is available on the host. If a machine is pulled into Saved State, Hyper-V may not be able to bring the VM back online if it can’t allocate a continuous block of RAM. Note that theremay be sufficient total RAM available but not enough to place a single block. You should therefore aim to keepat least 512 MB to 1 GB of RAM free when all VMs are powered up.

QUESTION 106
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.
VM3 is used to test applications.
You need to prevent VM3 from synchronizing its clock to Server1.
What should you configure?
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: I
Explanation:
By default when you install the Integration Services/Components you get time synchronization with the host OS, here is how to disable ongoing time synchronization. When you install the integration services/components in Hyper-V virtual machine you get a set of services installed and enabled by default.
Operating system shutdown
Time synchronization
Data exchange heartbeat
Backup via VSS
If you do not want the virtual machine to continuously synch its time to the Hyper-V host using the integration service, you can disable the integration service from the Hyper-V manager.
Open up the settings for the VM
Under Management, highlight the Integration Services option and you will get a list of the Integration
Services installed and enabled Uncheck the Time Synchronization service and press Apply. The virtual machine will now not sync its time with the Hyper-V host on a continuous basis….BUT it will always sync once at power on. This is required to boot strap the timer inside the virtual machine

Answer: B
Explanation:
B. Resource controls provide you with several ways to control the way that Hyper-V allocates resources to virtual machine
When you create a virtual machine, you configure the memory and processor to provide the appropriate computing resources for the workload you plan to run on the virtual machine. This workload consists of the guest operating system and all applications and services that will run at the same time on the virtual machine.
Resource controls provide you with several ways to control the way that Hyper-V allocates resources to virtual machines.
Virtual machine reserve. Of the processor resources available to a virtual machine, specifies the percentage that is reserved for the virtual machine. This setting guarantees that the percentage you specify will be available to the virtual machine. This setting can also affect how many virtual machines you can run at one time.
Virtual machine limit. Of the processor resources available to a virtual machine, specifies the maximum percentage that can be used by the virtual machine. This setting applies regardless of whether other virtual machines are running.
Relative weight. Specifies how Hyper-V allocates resources to this virtual machine when more than one virtual machine is running and the virtual machines compete for resources.

QUESTION 110
Your network contains an Active Directory domain named contoso.com. The network contains a member server named Server1 that runs Windows Server 2012 R2. Server1 has the DNS Server server role installed and has a primary zone for contoso.com. The Active Directory domain contains 500 client computers. There are an additional 20 computers in a workgroup. You discover that every client computer on the network can add its record to the contoso.com zone.
You need to ensure that only the client computers in the Active Directory domain can register records in the contoso.com zone.
What should you do first?
A. Move the contoso.com zone to a domain controller that is configured as a DNS server
B. Configure the Dynamic updates settings of the contoso.com zone
C. Sign the contoso.com zone by using DNSSEC
D. Configure the Security settings of the contoso.com zone.
Answer: A
Explanation:
If you install DNS server on a non-DC, then you are not able to create AD-integrated zones. DNS update security is available only for zones that are integrated into AD DS. When you directory- integrate a zone, access control list (ACL) editing features are available in DNS Managerso that you can add or remove users or groups from the ACL for a specified zone or resource record. http://technet.microsoft.com/en-us/library/cc771255.aspx

1. Active Directory’s DNS Domain Name is NOT a single label name (“DOMAIN” vs the minimal requirement of”domain.com.” “domain.local,” etc).
2. The Primary DNS Suffix MUST match the zone name that is allowing updates. Otherwise the client doesn’tknow what zone name to register in.
You can also have a different Conneciton Specific Suffix in addition to thePrimary DNS Suffix to register into that zone as well.
3. AD/DNS zone MUST be configured to allow dynamic updates, whether Secure or Secure and Non-Secure.
For client machines, if a client is not joined to the domain, and the zone is set to Secure, it will not registereither.
4. You must ONLY use the DNS servers that host a copy of the AD zone name or have a reference to get tothem. Do not use your ISP’s, an external DNS adddress, your router as a DNS address, or any other DNS thatdoes not have a copy of the AD zone. Internet resolution for your machines will be accomplished by the Rootservers (Root Hints), however it’s recommended to configure a forwarder for efficient Internet resolution. .
5. The domain controller is multihomed (which means it has more than one unteamed, active NIC, more thanone IP address, and/or RRAS is installed on the DC).
6. The DNS addresses configured in the client’s IP properties must ONLY reference the DNS server(s) hostingthe AD zone you want to update in. This means that you must NOT use an external DNS in any machine’s IP property in an AD environment.
You can’t mix them either. That’s because of the way the DNS Client side resolver service works. Even if youmix up internal DNS and ISP’s DNS addresses, the resolver algorithm can still have trouble asking the correctDNS server. It will ask the first one first. If it doesn’t get a response, it removes the first one from the eligibleresolvers list and goes to the next in the list. It will not go back to the first one unless you restart the machine,restart the DNS Client service, or set a registry entry to cut the query TTL to 0. The rule is to ONLY use yourinternal DNS server(s) and configure a forwarder to your ISP’s DNS for efficient Internet resolution.
This is the reg entry to cut the query to 0 TTL:
The DNS Client service does not revert to using the first server …The Windows 2000 Domain Name System (DNS) Client service (Dnscache) follows a certain algorithm when it decides the order in which to use the DNSservers …

7. For DHCP clients, DHCP Option 006 for the clients are set to the same DNS server.
8. If using DHCP, DHCP server must only be referencing the same exact DNSserver(s) in it’s own IP properties in order for it to ‘force’ (if you setthat setting) registration into DNS. Otherwise, how would it know which DNSto send the reg data to?
9. If the AD DNS Domain name is a single label name, such as “EXAMPLE”, and not the proper format of”example.com” and/or any child of that format, such as “child1.example.com”,
then we have a real big problem.
DNS will not allow registration into a single label domain name.
This is for two reasons:
1. It’s not the proper hierachal format. DNS is hierarchal, but a single label name has no hierarchy.
It’s just asingle name.
2. Registration attempts causes major Internet queriesto the Root servers. Why? Because it thinks thesingle label name, such as “EXAMPLE”, is a TLD(Top Level Domain), such as “com”, “net”, etc. Itwill now try to find what Root name server out therehandles that TLD. In the end it comes back to itselfand then attempts to register. Unfortunately it doe NOTask itself first for the mere reason it thinks it’s a TLD.
(Quoted from Alan Woods, Microsoft, 2004):
“Due to this excessive Root query traffic, which ISC found from a study that discovered Microsoft DNS serversare causing excessive traffic because of single label names, Microsoft, being an internet friendly neighbor andwanting to stop this problem for their neighbors, stopped the ability to register into DNS with Windows 2000SP4, XP SP1, (especially XP,which cause lookup problems too), and Windows 2003. After all, DNS ishierarchal, so therefore why even allow single label DNS domain names?”
The above also *especially* Applies to Windows Vista, &, 2008, 2008 R2, and newer.
10. ‘Register this connection’s address” on the client is not enabled under the NIC’s IP properties, DNS tab.
11. Maybe there’s a GPO set to force Secure updates and the machine isn’t a joined member of the domain.
12. ON 2000, 2003 and XP, the “DHCP client” Service not running. In 2008/Vista and newer, it’s the DNSClient Service. This is a requirement for DNS registration and DNS resolution even if the client is not actuallyusing DHCP.
13. You can also configure DHCP to force register clients for you, as well as keep the DNS zone clean of old orduplicate entries. See the link I posted in my previous post.
