Your company named Contoso, Ltd. runs Windows Server 2008 R2. You manage a Web server
named Server1. Internet users access Server1 by using http://www.contoso.com and
https://www.contoso.com. The Server1 server uses an SSL certificate from a public certification
authority (CA). You install an additional Web server named Server2. You configure a Network Load
Balancing cluster to distribute the incoming HTTP and HTTPS traffic between both Web servers. You
need to configure an SSL certificate on Server2 to support HTTPS connections. You must ensure that
all users can connect to https://www.contoso.com without receiving security warnings. What should
you do?

A.
Open the Internet Information Services (IIS) Manager console on Server2. Create a self- signed
certificate.

B.
Open the Internet Information Services (IIS) Manager console on Server1. Export the SSL
certificate to a .pfx file. Import the .pfx file to Server2.

C.
Open the Certificates snap-in on Server1. Export the SSL certificate to a .cer file. Import the .cer
file to Server2.

D.
Request a new SSL certificate from the public CA. Use Server2 as the Common Name in the
request. Install the new certificate on Server2.

Explanation:
To export a certificate in PFX format using IIS Manager:
Start IIS Manager. Click Start, point to Administrative Tools, and then click Internet
Information Services (IIS) Manager.
In the console tree, click the name of the computer.
In the IIS section of the center pane, double-click Server Certificates.
Right-click the certificate (.cer file) in the center pane, and then click Export.
Select the location for the exported file, type the name for the file (with the .pfx extension), and
then type and confirm the password to encrypt the private key.
