You have an Exchange Server 2013 organization that contains a server named Server1. Server1 has
an IP address of 10.1.100.16 and is configured to use a default gateway of 10.1.100.1. You deploy a
hardware load balancer that is configured to use the IP addresses of 192.168.101.31 and
10.1.100.31.
A user named User1 has a client computer that has an IP address of 102.168.101.201. User1 reports
that he cannot view his mailbox by using Outlook Web App. When you review the IIS logs on
Server1, you discover the following information:
#Fields: date time cs-method cs-uri-stem s-port c-ipcs(Referer) sc-status2013-01-09 00:08:55 POST
/owa/ev.owa2 443 192.168.101.201 https://owa.fabrikam.com/owa/ 200
You need to ensure that User1 can access his mailbox successfully from Outlook Web App.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

A.
Configure the hardware load balancer to use the same certificate as the certificate used on
Server1.

B.
Configure the hardware load balancer to use source NAT (SNAT).

C.
Configure the computer of User1 to ignore response headers.

D.
Modify the default gateway of Server1.

Explanation:
Source NAT
When using source NAT, the client IP address is not passed to the load balanced server. The insertion
of the Client IP address into the header allows the servers to see the IP that made the connection
They are then able to return the requested information correctly
B

Configuring the hardware load balancer to use source NAT (SNAT) will resolve the problem.
D
Changing the default gateway of Server1 to that of the hardware load balancer will ensure that the
connection to Server1 will be returned via the network load balancer and out to User1
NOT A
Not a certificate problem
NOT C
NOT a http response header issue
HTTP response header
The information, in the form of a text record, that a Web server sends back to a clients browser in
response to receiving an HTTP request.
The response header contains the date, size and type of file that the server is sending back to the
client and also data about the server itself.
The header is attached to the files being sent back to the client.
