- The cluster will consist of two nodes named Node1 and Node2.
- The quorum mode for the cluster will be set to Node and Disk Majority.
- A user named Admin1 will configure the virtual switch configuration of the VMs.
- The cluster nodes will use shared storage on an iSCSI Storage Area Network (SAN).

The Forefront TMG server will be configured as a Web proxy.
EXISTING ENVIRONMENT
The research department is located in the branch office.
Research users frequently travel to the main office.

The relevant sites for the network are configured shown in the following table.

The relevant group policy objects (GPOs) are configured as shown in the following table.

Existing Network Infrastructure
All users run windows server 2008 R2.
The relevant servers are configured as shown in following table.

WSUS2 is configured as a downstream replica server.
File1 contains a share named Templates.
Users access the Templates share by using the path \fabrikam.comdfstemplates.
File1 has the Distributed File System (DFS) Replication role service and the DFS Namespaces role service installed.
TECHNICAL REQUIREMENTS
Fabrikam must meet the following requirements:
- Minimize the cost of IT purchases.
- Minimize the potential attack surface on the servers.
- Minimize the number of rights assigned to administrators.
- Minimize the number of updates that must be installed on the servers.

Fabrikam must meet the following requirements for the Templates share:
- Ensure that users access the files in the Templates share from a server in their local site.
- Ensure that users always use the same UNC path to access the Templates share, regardless of the site in which the users are located.

QUESTION 161
You need to configure Internet Explorer to meet the company's technical requirements.
Which GPO or GPOs should you modify?

A.    Default Domain Policy
B.    GPO1
C.    GPO2 and GPO3
D.    GPO4 and GPO5

Answer: D
Explanation:
The company has 2 sites
He following list contains example applications of policy:
A GPO linked to a site applies to all users and computers in the site.
A GPO applied to a domain applies to all users and computers in the domain and, by inheritance, to all users and computers in child organizational units. Be aware that policy is not inherited across domains.
A GPO applied to an organizational unit applies directly to all users and computers in the organizational unit and, by inheritance, to all users and computers in child organizational units.

QUESTION 162
You need to recommend the minimum number of logical unit numbers (LUNs) that must be provisioned for Cluster1.
The recommendation must support the company's planned changes.
Which number should you recommend?

A.    1
B.    2
C.    8
D.    9

Answer: B

QUESTION 163
You need to recommend a strategy for delegating administrative rights to Admin1.

What should you include in the recommendation?

A.    the Authorization Manager snapin on Node1 and Node2
B.    the Authorization Manager snapin on the VMs

D.    the Network Configuration Operators local group on Node1 and Node2

Answer: A
Explanation:
http://technet.microsoft.com/en-us/library/cc731364.aspx ¹
An authorization store can contain authorization policy information for many applications in a single policy store. All applications in one authorization store can access all of the groups defined at the store level.
You must be assigned to the Authorization Manager Administrator user role to complete this procedure. By default, Administrators is the minimum Windows group membership assigned to this role. Review the details in "Additional considerations" in this topic

QUESTION 164
You need to configure Windows Update to meet the company's technical requirements.
What should you do?

A.    Configure WSUS2 as an autonomous server.
B.    Create a Network Load Balancing (NLB) cluster.
C.    Create multiple Host (A) records and use round robin DNS.
D.    Configure multiple service location (SRV) records and use round robin DNS.

Answer: B
Explanation:
http://technet.microsoft.com/en-us/library/dd939896%28WS.10%29.aspx ²
Network load balancing (NLB) is an optional feature of Windows Server that load balances network traffic for high availability. You can install Windows Server Update Services (WSUS) 3.0 SP2 in a network that uses NLB, but this configuration requires that you perform additional steps during WSUS setup.

QUESTION 165
You need to protect the confidential data files on File2 against unauthorized offline access.
What should you use?

A.    Encrypting File System (EFS) on File2
B.    file screens on Node1 and Node2
C.    NTFS permissions on File2
D.    Windows BitLocker Drive Encryption (BitLocker) on Node1 and Node2

Answer: A
Explanation:
http://technet.microsoft.com/en-us/library/cc749610%28WS.10%29.aspx ³
Per-user encryption of offline files Offline copies of files from remote servers can also be encrypted by using EFS. When this option is enabled, each file in the offline cache is encrypted with a public key from the user who cached the file. Thus, only that user has access to the file, and even local administrators cannot read the file without having access to the user's private keys.

QUESTION 166
You need to recommend a file access solution for the Templates share.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A.    Add File2 as a namespace server for \fabrikam.comdfs.

Answer: D
Explanation:
http://support.microsoft.com/kb/947032 ⁵
SSTP is a new kind of Virtual Private Networking (VPN) tunnel that is available in the Routing and
Remote Access Server role in Windows Server 2008. SSTP allows for Point-to-Point Protocol
(PPP) packets to be encapsulated over HTTP. This allows for a VPN connection to be more easily established through a firewall or through a Network Address Translation (NAT) device. Also, this allows for a VPN connection to be established through an HTTP proxy device.
The information is this article is more likely to apply to a small-sized or medium-sized organization.
For these kinds of organizations, it is common to have one public IP address that is assigned to the external interface of a NAT router or of a gateway device.
This article describes the following scenario:
You have a Windows Server 2008-based Secure Socket Tunneling Protocol (SSTP)-based VPN server.
The server is assigned a private IP address.
The server is located on an internal network behind a NAT device.
