You run the Get-DNSServer cmdlet on DC01 and receive the following output:

You need to recommend changes to DC01. Which attribute should you recommend modifying?

A. EnablePollutionProtection

B. isReadOnly

C. Locking Percent

D. ZoneType

Explanation:

* Scenario: The DNS servers must be prevented from overwriting the existing DNS entries that have been stored in cache.

* Cache locking is configured as a percent value. For example, if the cache locking value is set to 50, then the DNS server will not overwrite a cached entry for half of the duration of the TTL. By default, the cache locking percent value is 100. This means that cached entries will not be overwritten for the entire duration of the TTL. The cache locking value is stored in the CacheLockingPercent registry key. If the registry key is not present, then the DNS server will use the default cache locking value of 100.

Topic 3, Litware, Inc

Overview

Litware, Inc., is a manufacturing company. The company has a main office and two branch offices. The main office is located in Seattle. The branch offices are located in Los Angeles and Boston.

Existing Environment

Active Directory

The network contains an Active Directory forest named litwareinc.com. The forest contains a child domain for each office. The child domains are named boston.litwareinc.com and la.litwareinc.com. An ActiveDirectory site exists for each office.

In each domain, all of the client computer accounts reside in an organizational unit (OU) named AllComputers and all of the user accounts reside in an OU named AllUsers.

All domain controllers run Windows Server 2008 R2 and are configured as DNS servers.

The functional level of the domain and the forest is Windows Server 2008.

Network Infrastructure

The main office has the following servers:

Five physical Hyper-V hosts that run Windows Server 2012

Three virtual fileservers that run Windows Server 2008 R2

One physical DHCP server that runs Windows Server 2008 R2

Ten physical application servers that run Windows Server2012

One virtual IP Address Management (IPAM) server that runs Windows Server 2012

One virtual Windows Server Update Services (WSUS) server that runs Windows Server 2008 R2

One physical domain controller and two virtual domain controllers that run Windows Server 2008 R2

Each branch office has following servers:

One virtual file server that runs Windows Server 2008 R2

Two physical Hyper-V hosts that run Windows Server 2012

One physical DHCP server that runs Windows Server 2008 R2

One physical domain controller and two virtual domain controllers that run Windows Server 2008 R2

All of the offices have a high-speed connection to the Internet. The offices connect to each other by using T1 leased lines.

The IPAM server in the main office gathers data from the DNS servers and the DHCP servers in all of the offices.

Requirements

Planned Changes

The company plans to implement the following changes:

Implement the Active Directory Recycle Bin.

Implement Network Access Protection (NAP).

Implement Folder Redirection in the Boston office only.

Deploy an application named Appl to all of the users in the Boston office only.

Migrate to IPv6 addressing on all of the servers in the Los Angeles office. Some application servers in the Los Angeles office will have only IPv6 addresses.

Technical Requirements

The company identifies the following technical requirements:

Minimize the amount of administrative effort whenever possible.

Ensure that NAP with IPSec enforcement can be configured.

Rename boston.litwareinc.com domain tobos.litwareinc.com.

Migrate the DHCP servers from the physical servers to a virtual server that runs Windows Server 2012.

Ensure that the members of the Operators groups in all three domains can manage the IPAM server from their client computer.

VPN Requirements

You plan to implement a third-party VPN server in each office. The VPN servers will be configured as RADIUS clients. A server that runs Windows Server 2012 will perform RADIUS authentication for all of the VPN connections.

Visualization Requirements

The company identifies the following

virtualization requirements:

Virtualize the application servers.

Ensure that the additional domain controllers for the branch offices can be deployed by using domain controller cloning.

Automatically distribute the new virtual machines to Hyper-V hosts based on the current resource usage of the Hyper-V hosts.

Server Deployment Requirements

The company identifies the following requirements for the deployment of new servers on the network:

Deploy the new servers over the network.

Ensure that all of the server deployments are done by using multicast.

Security Requirements

A new branch office will open in Chicago. The new branch office will have a single read-only domain controller (RODC). Confidential attributes must not be replicated to the Chicago office.
