You are the administrator of a Windows Essential Business Server (EBS) 2008 environment. You install Forefront Threat Management Gateway (TMG) on the Security Server.
You configure Remote Web Workplace on the network to enable users to access network resources from remote locations. Currently, users access Remote Web Workplace through srv.nutex.com. You want to change the public domain name that will be used by users to access Remote Web Workplace to remote.nutex.com. You need to create the appropriate record in DNS to register the new public domain name for Remote Web Workplace.
What type of record must you create?
A.
A CNAME record
B.
An A record
C.
A PTR record
D.
A SRV record
Explanation:
You must create a CNAME or canonical name record in the DNS. By default, users use a public domain name to access Remote Web Workplace that was configured during the installation of Windows EBS. You can change this public domain name for Remote Web Workplace by modifying the properties of the Remote Web Workplace publishing rule in Forefront TMG. Before modifying this publishing rule, you must ensure that the new public domain name is registered with the DNS server. To register the new public domain name for Remote Web Workplace in DNS, you must create a CNAME record in the public DNS that points to the host (A) record for the external address of the Security Server. You should perform the following steps to change the Remote Web Workplace public domain name:1. Open the Windows Essential Business Server Administration Console.
2. Click the Security tab, click the Network firewall option, and then, click the Start Forefront Threat Management Gateway console option in the tasks pane.
3. In the console tree, expand the name of your Security Server, and then click the Firewall Policy option.
4. In the Results pane, double-click the Remote Web Workplace Publishing Rule.
5. Click the Public Name tab.
6. Under the Web sites and IP addresses heading, click your present remote name, and then click the Edit button.
7. In the Public Name dialog box, type a new public domain name (in this case – remote.nutex.com) and then click OK twice.
8. To save changes and update the configuration, click Apply.You should not create an A, PTR, or SRV record in the DNS to register the new public domain name for Remote Web Workplace because a CNAME record is required for this purpose. An A record, also known as a Host record, is used to map machine or resource host names to IP addresses. A PTR record, also known as a Pointer record, is used for reverse lookup queries to resolve IP address to names. A SRV, also known as a Service Location record, is used to locate Active Directory infrastructure services.
