Your network contains an Active Directory forest. The forest contains three domain trees. Each domain tree contains multiple domains.
You have an Active Directory-integrated DNS zone.
You install a Web server named Web1. All of the users in the company will use Web1. You need to ensure that the users can access Web1 by using the URL http://web1. You want to achieve this goal by using the minimum amount of administrative effort.
What should you do?
A.
Configure a GlobalNames zone and add a Host (A) resource record for Web1.
B.
Create an Alias (CNAME) resource record for Web1 in the forest root domain zone.
C.
Create a reverse lookup zone and add an Alias (CNAME) resource record for Web1.
D.
Create a Host Information (HINFO) resource record for Web1 in the forest root domain zone.
I think correct answer is B.
—- Plan a DNS alias (CNAME) record for your Web server
Alias (CNAME) resource records are also sometimes called canonical name resource records. With these records, you can use more than one name to point to a single host, making it easy to do such things as host both a File Transfer Protocol (FTP) server and a Web server on the same computer. For example, the well-known server names (ftp, www) are registered using alias (CNAME) resource records that map to the Domain Name System (DNS) host name, such as WEB1, for the server computer that hosts these services.
Alias (CNAME) resource records use FQDNs (Fully Qualified Domain Names). An example of a FQDN is: web1.contoso.com
The questions states that one should be able to access WEB1 by using the URL http://web1 which is not a FQDN. Answer is A.
Well, paul, 1 year later, a big thanks for this explanation found by surfing the web while studying for some certifs
