QUESTION 11
Your company has a main office and a branch office.
The company has a single-domain Active Directory forest.
The main office has two domain controllers named DC1 and DC2 that run Windows Server 2008 R2.
The branch office has a Windows Server 2008 R2 read-only domain controller (RODC) named DC3.
All domain controllers hold the DNS Server role and are configured as Active Directory-integrated zones.
The DNS zones only allow secure updates.
You need to enable dynamic DNS updates on DC3.
What should you do?
A. Run the Dnscmd.exe /ZoneResetType command on DC3.
B. Reinstall Active Directory Domain Services on DC3 as a writable domain controller.
C. Create a custom application directory partition on DC1.
Configure the partition to store Active Directory-integrated zones.

QUESTION 12
Your company has an Active Directory domain named ad.contoso.com.
The domain has two domain controllers named DC1 and DC2.
Both domain controllers have the DNS server role installed.

You configure DC1 to forward all unresolved name requests to DNS1.contoso.com.
You discover that the DNS forwarding option is unavailable on DC2.
You need to configure DNS forwarding on the DC2 server to point to the DNS1.contoso.com server.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Clear the DNS cache on DC2.
B. Configure conditional forwarding on DC2.
C. Configure the Listen On address on DC2.
D. Delete the Root zone on DC2.
Answer: BD
Explanation:
Delete the Root zone on DC2.
Configure conditional forwarding on DC2.

Configure a DNS Server to Use Forwarders
A forwarder is a Domain Name System (DNS) server on a network that is used to forward DNS queries for external DNS names to DNS servers outside that network.
You can also configure your server to forward queries according to specific domain names using conditional forwarders.

Deleting .root dns zone in 2008 DNS
Q: We have 2 domain controllers and .root zone is created in the DNS. Due to which the external name resolution is not possible. I had tried to add conditional forwarders but i get an error saying that conditional forwarders cannot be created on root DNS servers. A 1: If you have a “root” zone created in your DNS, and you no longer want that configuration, you can just simply delete that zone. There is no reason to have a root “.” zone hosted unless you want to make sure that the DNS server is authoritative for all queries and not allow the DNS server to go elsewhere for name resolution.
If you delete this zone, the DNS server will be able to use its root hints, or fowarders to resolve queries for zones its not authoritative for.
A 2: That was from the old 2000 days where DCPROMO would create it if it detected no internet access while promoting the first DC. Just remove it, and the Forwarders option reappear.
QUESTION 13
Your company has an organizational unit named Production.
The Production organizational unit has a child organizational unit named R&D.
You create a GPO named Software Deployment and link it to the Production organizational unit.
You create a shadow group for the R&D organizational unit.
You need to deploy an application to users in the Production organizational unit.
You also need to ensure that the application is not deployed to users in the R&D organizational unit.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Configure the Block Inheritance setting on the R&D organizational unit.
B. Configure the Enforce setting on the software deployment GPO.
C. Configure security filtering on the Software Deployment GPO to Deny Apply group policy for
the R&D security group.
D. Configure the Block Inheritance setting on the Production organizational unit.
Answer: AC
Explanation:
Configure the Block Inheritance setting on the R&D organizational unit.
Configure security filtering on the Software Deployment GPO to Deny Apply group policy for the R&D security group.

Managing inheritance of Group Policy
Blocking Group Policy inheritance
You can block policy inheritance for a domain or organizational unit.
Using block inheritance prevents GPOs linked to higher sites, domains, or organizational units from being automatically inherited by the child-level. By default, children inherit all GPOs from the parent, but it is sometimes useful to block inheritance. For example, if you want to apply a single set of policies to an entire domain except for one organizational unit, you can link the required GPOs at the domain level (from which all organizational units inherit policies by default) and then block inheritance only on the organizational unit to which the policies should not be applied.
Enforcing a GPO link You can specify that the settings in a GPO link should take precedence over the settings of any child object by setting that link to Enforced. GPO-links that are enforced cannot be blocked from the parent container. Without enforcement from above, the settings of the GPO links at the higher level (parent) are overwritten by settings in GPOs linked to child organizational units, if the GPOs contain conflicting settings. With enforcement, the parent
GPO link always has precedence.
By default, GPO links are not enforced. In tools prior to GPMC, “enforced” was known as “No override.”
In addition to using GPO links to apply policies, you can also control how GPOs are applied by using security filters or WMI filters.
http://technet.microsoft.com/en-us/library/cc781988%28v=ws.10%29.aspx
Security filtering using GPMC
Security filtering Security filtering is a way of refining which users and computers will receive and apply the settings in a Group Policy object (GPO). Using security filtering, you can specify that only certain security principals within a container where the GPO is linked apply the GPO. Security group filtering determines whether the GPO as a whole applies to groups, users, or computers; it cannot be used selectively on different settings within a GPO.

Understanding Active Directory Domain Services (AD DS) Functional Levels
Functional levels determine the available Active Directory Domain Services (AD DS) domain or forest capabilities. They also determine which Windows Server operating systems you can run on domain controllers in the domain or forest.
However, functional levels do not affect which operating systems you can run on workstations and member servers that are joined to the domain or forest.
Features that are available at domain functional levels
Windows Server 2008
All of the default AD DS features, all of the features from the Windows Server 2003 domain functional level, and the following features are available:
– Advanced Encryption Standard (AES 128 and AES 256) support for the Kerberos protocol.
In order for TGTs to be issued using AES, the domain functional level must be Windows Server 2008 or higher and the domain password needs to be changed.

Answer: BD

Specifying Group Policy for Slow Link Detection
Administrators can partially control which Group Policy extensions are processed over a slow link. By default, when processing over a slow link, not all components of Group Policy are processed.
Table 2.6 shows the default settings for processing Group Policy over slow links.
Administrators can use a Group Policy setting to define a slow link for the purposes of applying and updating Group Policy. The default value defines a rate slower than 500 Kbps as a slow link.

Assigning and Publishing Software
Assigning software to computers
After you assign a software package to computers in a site, domain, or OU, the software is installed the next time the computer restarts or the user logs on.
