what is the correct answer?

[Thiyagu_2]

This is the question asked in Exchange server 2003 exam. I don't know the correct answer.

Could you guys help me.

Question: 123.
You are the Exchange administrator for Examsheets. The network consists of two subnets. All
client computers are located in one subnet. All servers are located in a central data center that
uses a single IP subnet. The data center contains the hosts shown in the following table.
Host Name Role IP address
Router 1 Router 10.1.1.1.
Router 2 Router 10.1.1.2
Router 3 Router 10.1.255.1
DC1 Domain Controller 10.1.10.1
DC2 Domain Controller 10.1.10.2
Examsheets1 Mail Server 10.1.11.1
Examsheets 2 Mail Server 10.1.11.2
You install Exchange Server 2003 on a new computer in the data center. The computer is named
Examsheets3. After installation, the network administrator makes some changes to the TCP/IP
settings of Examsheets3 as shown in the following table.
Parameter Value
IP Address 101.1.13
Subnet Mask 255.255.255.0
Default Gateway 101.1.1.2
You discover that Examsheets3 cannot communicate with any of the other servers. You test
network connectivity on Examsheets3 by using the ping command. When you attempt to ping
DC1, you receive the following error message: "Destination host unreachable".
You need to ensure that Examsheets3 can communicate with all computers on the network.
What should you do?
A. Change the IP address of Examsheets3 to 10.1.10.3.
B. Change the IP address of Examsheets3 to 10.1.11.3.
C. Change the subnet mask of Examsheets3 to 255.255.0.0.
D. Change the default gateway of Examsheets3 to 10.1.1.1.

thanks in advance

The answer should be D

However, you have a typ'O with the IP address of Examsheets3?

[Rune J. Winje]

B & D
(if there is no typo in the question.)


Cheers,
Rune

There is a typo in the question.

The following sentence makes no sense:
IP Address 101.1.13

In case you typed it wrong, the answer is without any doubt C.

C. Change the subnet mask of Examsheets3 to 255.255.0.0.

All of the hosts within data center subnet have a 16 bits subnet mask.

regards.
Good luck with your exam!

Answer should be B and D

[Ron Kinner]

Would be easier without the typos but Edgar is correct. C. Everybody at the data center has to be in the same subnet and they wouldn't be with a 255.255.255.0 subnet mask. With a 255.255.0.0 mask everybody IS in the same subnet.


If we did A, with a mask of 255.255.255.0 and an IP address of 10.1.10.3 we could not talk to anyone but other 10.1.10.x machines. Couldn't get to the 10.1.11.x.

Same problem but reversed with B.

D. doesn't help because the gateway is only used when talking to someone not on the same subnet and they told us at the beginning that everyone at the data center was on the same subnet.

I do wonder at the error message tho. I'm not convinced that you would get the error: "Destination host unreachable". I would expect to just see: "Request timed out." but I've never worked with Win2003 so maybe ping has learned new tricks.

101.1.1.x IP is totally out side the scope.

With the Subnet Mask 255.255.255.0, you get the following:

Subnet host address range 10.1.1.1-10.1.1.254
Subnet bits 16/24 mask bits
Max Subnets 65534
Max hosts 254
Subnet ID 10.1.1.0
Subnet Broadcast 10.1.1.255

So your examsheets3 Server with the following IP settings should work

IP Address 10.1.1.13
Subnet Mask 255.255.255.0
Default Gateway 10.1.1.12

Hope this help

Typ'O

So your examsheets3 Server with the following IP settings should work

IP Address 10.1.1.13 or if you meant 10.1.1.3
Subnet Mask 255.255.255.0
Default Gateway 10.1.1.1 or 10.1.1.2

Sorry for the confusion
