That one is pretty good. I passed MCP 70-270 on Wednesday.

QUESTION 1:
You work as the network administrator at Certkiller .com. The Certkiller .com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003 and all client
computers run Windows XP Professional.
The Certkiller .com network is segmented into two subnets:
1. Subnet A has a network ID of 192.123.88.0/27 and contains a DHCP server, a
RRAS server and several client computers.
2. Subnet B has a network ID of 192.123.88.32/27 and contains a domain controller
and several client computers.
Several Sales users connect to the corporate network by using laptop computers.
Only three Sales employees can connect to the corporate network at any single point
in time. You add several new client computers to the network. Shortly after this,
numerous users on each of the subnets complain that they cannot always connect to
the corporate network.
You investigate the issue and find that users can connect to network after rebooting
their computers later on in the day. You also find that some users in each of the
subnets have no problems connecting to the corporate network. On one of the new
client computers, you run the ipconfig utility to check its IP addressing
configuration. The IP address of this computer is 169.254.0.5. This client computer
resides in Subnet B. The 192.123.88.0/27 and 192.123.88.32/27 ranges are the only IP
addresses which Certkiller .com can use to assign to computers.
What should you do to enable all users to connect to the corporate network?
Actualtest.org – The Power of Knowing
A. For the DHCP scope for each subnet, shorten the duration of the lease.
B. Configure a static IP address for each of the new client computers.
C. For each current DHCP scope, add new IP addresses.
D. For the DHCP scope for Subnet B, shorten the duration of the lease.
Answer: A
Explanation: The issue you have is that while IP addresses are being released by
client computers, the lease durations for each scope are set up so that it is
unavailable for assignment in the DHCP scope on the DHCP server. You can
resolve this issue by shortening the duration of the lease for the DHCP scope for
each subnet. This will result in IP addresses being released for reassignment to the
DHCP server on the network.
Incorrect answers:
B: While this could resolve your issue in the interim, your other client computers on the
network will still be impacted by the shortage of IP addresses.
C: The question states that the 192.123.88.0/27 and 192.123.88.32/27 ranges are the only
IP addresses which Certkiller .com can use.
D: You have to shorten the duration of the lease for each subnet. Doing so for one subnet
will result in the other subnet still experiencing the issue.
QUESTION2:
You work as the network administrator at CertKiller.com. The CertKiller.com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the CertKiller.com network run Windows Server 2003 and all client
computers run Windows XP Professional. A server named Certkiller -SR26 runs
the DHCP Server service. The two file servers on the network are named
Certkiller -SR03 and Certkiller -SR04.
The CertKiller.com network is segmented into two subnets:
1. Subnet 192.168.11.0 contains the DHCP server, Certkiller -SR03, and several
client computers.
2. Subnet 192.168.12.0 contains Certkiller -SR04 and several client computers.
The current scope configuration of Certkiller -SR26 is as follows:
1. Range 192.168.11.10 – 192.168.11.200.
2. Range 192.168.12.10 – 192.168.12.200.
You replace the router running between Subnet 192.168.11.0 and Subnet
192.168.12.0 with a router that does not support BOOTP forwarding. You
immediately receive complaints from users that reside in Subnet 192.168.12.0. Users
can no longer connect to the CertKiller.com corporate network from Subnet
192.168.12.0. You access the client computer of a user that complained and discover
that the IP assigned to client computer is 169.254.3.8.
You need to ensure that all users that have client computers in the subnet can
connect to the CertKiller.com corporate network.
Actualtest.org – The Power of Knowing
What should you do? (Each correct answer presents part of the solution. Choose
TWO.)
A. On Certkiller -SR04 in Subnet 192.168.12.0, enable the DHCP Relay Agent.
B. On Certkiller -SR26 in Subnet 192.168.11.0, enable the DHCP Relay Agent.
C. On Certkiller -SR03 in Subnet 192.168.11.0, enable the DHCP Relay Agent.
D. Use an alternate IP configuration to assign IP addressing configuration to
Certkiller -WS166.
E. Replace the router with a router that supports BOOTP forwarding.
Answer: A, E
Explanation: You have a router that does not support BOOTP forwarding. You
router will therefore drop DHCP broadcast messages because it is not configured to
forward them, and there is no DHCP Relay Agent. Similarly, the DHCP lease
process would not be able to occur. The initial message sent by a DHCP client is a
broadcast message. In your scenario, the new router does not support BOOTP
forwarding. In a routed network, you need a router that supports BOOTP
forwarding or you need DHCP Relay Agents if you plan to implement only one
DHCP server. To enable clients to obtain IP addresses from a DHCP server on a
remote subnet, you have to configure the DHCP Relay Agent on the subnet that
contains the remote clients (Subnet 192.168.12.0), so that it can relay DHCP
broadcast messages to your DHCP server in Subnet 192.168.11.0.
Incorrect answers:
B, C: The DHCP Relay Agent must reside in the subnet that does not contain a DHCP
server. Subnet 192.168.11.0 contains the DHCP server.
D: You would usually configure alternate IP address configuration parameters when the
DHCP server cannot be accessed. Configuring the alternate IP address configuration is
ideal for laptop computers which connect to a number of different networks. In your case,
enabling the DHCP Relay Agent on Certkiller -SR04 in Subnet 192.168.12.0 would
resolve the issue of client computers in
Subnet 192.168.11.0 not being able to access the DHCP server.
QUESTION 3:
You work as the network administrator at Certkiller .com. The Certkiller .com
network consists of a single Active Directory domain named Certkiller .com. All
servers on the Certkiller .com network run Windows Server 2003 and all client
computers run Windows XP Professional.
A server named Certkiller -SR25 runs the DHCP Server service. A domain
controller named Certkiller -DC01 runs the DNS Server service. All client
computers are DHCP clients. You deploy several new printers on the Certkiller .com
network. You need to assign IP addresses to the new printers. You do not want to
perform this task manually. You decide to configure all new printers to be assigned
IP addresses from the DHCP server.
Actualtest.org – The Power of Knowing
Users complain that that they cannot connect to either of the new printers. You need
to ensure that all users can print to the print servers.
The current configuration of Certkiller -SR25 is shown in the exhibit.
What should you do?
A. Remove the client IP address reservation for the printers.
B. Delete all IP address exclusions in the DHCP scope on Certkiller -SR25.
C. Increase the lease period for the scope.
D. Run the ipconfig.exe /renew command on all print servers.
Answer: B
Explanation: The issue that is preventing the IP addresses from being assigned to
the printers is that these addresses are currently part of the IP address range
excluded from distribution. You have to first remove these IP addresses from the
exclusion range before you can reserve it for your printers.
Incorrect answers:
A: Removing the client IP address reservation for the printers would result in the printers
being assigned a different IP address by the DHCP server.
C: The lease period for the scope has no impact on the IP addresses assigned to a
computer by the DHCP server. The lease period would normally be increased when there
are numerous addresses and few computers.
D: Running the ipconfig.exe /renew command on the print servers will update the IP
configuration of the servers, but will not assign the reserved IP addresses for the printers.
