Answer: C

QUESTION 63
Your network contains two DHCP servers.
The DHCP servers are named DHCP1 and DHCP2.
The internal network contains 1,000 DHCP client computers that are located on a single subnet.
A router separates the internal network from the Internet.
The router has a single IP address on the internal interface.
DHCP1 has the following scope information:
– Starting IP address: 172.16.0.1
– Ending IP address: 172.16.7.255
– Subnet mask: 255.255.240.0
You need to provide a faulttolerant DHCP infrastructure that supports the client computers on the internal network.
In the event that a DHCP server fails, all client computers must be able to obtain a valid IP address.
How should you configure DHCP2?

A.    Create a scope for the subnet 172.16.0.0/20.
Configure the scope to use a starting IP address of 172.16.8.1 and an ending IP address of
172.16.15.254.
B.    Create a scope for the subnet 172.16.0.0/21.
Configure the scope to use a starting IP address of 172.16.0.1 and an ending IP address of
172.16.15.254.
C.    Create a scope for the subnet 172.16.8.0/21.
Configure the scope to use a starting IP address of 172.16.8.1 and an ending IP address of
172.16.10.254.
D.    Create a scope for the subnet 172.17.0.0/16.
Configure the scope to use a starting IP address of 172.17.0.1 and an ending IP address of
172.17.255.254.

Answer: A
Explanation:
Create a scope for the subnet 172.16.0.0/20.
Configure the scope to use a starting IP address of 172.16.8.1 and an ending IP address of 172.16.15.254.
Subnet 255.255.240.0 is a /20 subnet in CIDR notation, this allows for 4096 client IPs, ranging from 172.16.0.1 all the way to 172.16.15.254 as DHCP1 only used half of the available IPs then you should configure DHCP2 to use the other half.
http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing
as an aside you could consider the 80/20 design rule for balancing scope distribution of addresses where multiple DHCP servers are deployed to service the same scope.
Using more than one DHCP server on the same subnet provides increased fault tolerance for servicing DHCP clients located on it. With two DHCP servers, if one server is unavailable, the other server can take its place and continue to lease new addresses or renew existing clients.
A common practice when balancing a single network and scope range of addresses between two DHCP servers is to have 80 percent of the addresses distributed by one DHCP server and the remaining 20 percent provided by a second.

QUESTION 65
Your network consists of a single Active Directory domain.
The network contains two Windows Server 2008 R2 computers named Server1 and Server2.
The company has two identical print devices.
You plan to deploy print services.
You need to plan a print services infrastructure to meet the following requirements:
– Manage the print queue from a central location.
– Make the print services available, even if one of the print devices fails.
What should you include in your plan?

A.    Install and share a printer on Server1.
Enable printer pooling.
B.    Install the Remote Desktop Services server role on both servers.
Configure Remote Desktop Connection Broker (RD Connection Broker).
C.    Install and share a printer on Server1.
Install and share a printer on Server2.
Use Print Management to install the printers on the client computers.
D.    Add Server1 and Server2 to a Network Load Balancing cluster.
Install a printer on each node of the cluster.

Answer: A
Explanation:
http://www.techrepublic.com/blog/datacenter/configure-printer-pooling-in-windows-server-2008/964
Managing printers can be the bane of a Windows administrator. One feature that may assist you with this task is the Windows printer pooling feature. Windows Server 2008 offers functionality that permits a collection of multiple like-configured printers to distribute the print workload.
Printer pooling makes one share that clients print to, and the jobs are sent to the first available printer. Configuring print pooling is rather straightforward in the Windows printer configuration applet of the Control Panel. Figure A shows two like-modeled printers being pooled.
To use pooling, the printer models need to be the same so that the driver configuration is transparent to the end device; this can also help control costs of toner and other supplies. But plan accordingly — you don’t want users essentially running track to look for their print jobs on every printer in the office.

QUESTION 66
Your company has a main office and a branch office.
You plan to deploy a Readonly Domain Controller (RODC) in the branch office.
You need to plan a strategy to manage the RODC.
Your plan must meet the following requirements:
– Allow branch office support technicians to maintain drivers and disks on the RODC
– Prevent branch office support technicians from managing domain user accounts
What should you include in your plan?

A.    Configure the RODC for Administrator Role Separation.
B.    Configure the RODC to replicate the password for the branch office support technicians.
C.    Set NTFS permissions on the Active Directory database to Read & Execute for the branch
office support technicians.
D.    Set NTFS permissions on the Active Directory database to Deny Full Control for the branch
office support technicians.

QUESTION 70
Your network consists of a single Active Directory domain.
The network includes a branch office named Branch1.
Branch1 contains 50 member servers that run Windows Server 2008 R2.
An organizational unit (OU) named Branch1Servers contains the computer objects for the servers in Branch1.
A global group named Branch1admins contains the user accounts for the administrators. Administrators maintain all member servers in Branch1.
You need to recommend a solution that allows the members of Branch1admins group to perform the following tasks on the Branch1 member servers.
– Stop and start services
– Change registry settings
What should you recommend?

A.    Add the Branch1admins group to the Power Users local group on each server in Branch1.
B.    Add the Branch1admins group to the Administrators local group on each server in Branch1.
C.    Assign the Branch1admins group change permissions to the Branch1Servers OU and to all
child objects.
D.    Assign the Branch1admins group Full Control permissions on the Branch1Servers OU and
to all child objects.

Answer: B
Explanation:
Local admins have these rights.
Power Users do not
By default, members of the power users group have no more user rights or permissions than a standard user account. The Power Users group in previous versions of Windows was designed to give users specific administrator rights and permissions to perform common system tasks. In this version of Windows, standard user accounts inherently have the ability to perform most common configuration tasks, such as changing time zones. For legacy applications that require the same
Power User rights and permissions that were present in previous versions of Windows, administrators can apply a security template that enables the Power Users group to assume the same rights and permissions that were present in previous versions of Windows.
