Contoso, Ltd. has an Office 365 Enterprise E3 plan. Contoso uses the domain contoso.com for email and
instant messaging (IM).
Contoso requires that website visitors who go to http://contoso.com be directed to the company’s Microsoft
SharePoint Online public website.
You need to configure Office 365 to redirect the website requests without affecting the company’s email or IM.
What should you do?
A.
In the SharePoint admin center, rename the public website to http://contoso.com.
B.
In the Office 365 admin center, change the domain purpose for contoso.com to SharePoint.
C.
On the authoritative DNS servers, add a CNAME record for contoso.com.
D.
In the Office 365 admin center, add a new subdomain. Then set up redirection for http://contoso.com to the
subdomain.
Explanation:
In this question, we need to redirect users to the SharePoint public website by using a root domain,
Contoso.com. If we were using www.contoso.com, we could simply configure a CNAME record in DNS.
However, this question states that “You need to configure Office 365 to redirect the website requests without
affecting the company’s email or IM”. Email uses MX records. If you have a CNAME record at the root level of a
domain, the MX records will not work.
To use a root domain, we need to configure a redirect. First we need to add a subdomain such as
www.contoso.com in the Office 365 admin center then configure the redirect to the subdomain.
“If you want users to see your site when they type just the root domain, contoso.com, contact your DNS hosting
provider and ask if they have a URL redirection service to direct traffic from contoso.com to www.contoso.com.
Most providers offer URL redirection, and you can check their documentation to learn how to set it up.”

This question is outdated; SharePoint Online Public Websites are discontinued.
On March 9, 2015, Microsoft made changes to the SharePoint Online Public Websites feature by removing the ability to create a public website after the changeover date of March 9, 2015. Customers who used this feature before March 9, 2015, were provided continued access to the feature for a minimum of two years. New customers who subscribed to Office 365 after the changeover date of March 9, 2015, don’t have access to this feature.
