A network technician is setting up a web server for a small company. The company has obtained a domain name, company-a.com, from a domain registry service. The new web server is accessible through the IP address matching the domain. However, when the technician types company-a.com in the web browser, an error message displays saying that “The connection has timed out”. What is the problem?
- The DHCP server is down.
- The domain name resolution failed.
- The URL needs to be http://company-a.com.
- A web page named home.html is required to be created first.
Explanation: A web URL is in the form of protocol://domain-name/resource. The web server IP address can be used in place of domain-name. The resource is the file structure and file name under the web service. If the domain name is used in the URL, the IP address matching to the domain name must be found first through the name resolution process. HTTP is the default protocol by all web browsers so that a user is not required to type it when accessing a website. Also, home.html is not required for a web server to function. Even if the technician does not create any web page during the installation and configuration process, major web servers have a built-in mechanism to display a greeting message if the web server runs normally.
