What must be changed to allow remote site access to a newly configured web server?

  1. NTP

  2. STP

  3. DNS

  4. API

The correct answer is: DNS

Allowing remote site access to a newly configured web server typically involves the ability for users to locate and connect to that server over the Internet or within a private network. DNS, or Domain Name System, plays a crucial role in this process. When a web server is configured, it is often assigned a specific IP address. To make it accessible by a user-friendly domain name (such as www.example.com), changes must be made to the DNS records. This ensures that when users enter the domain name in their browser, the DNS system translates that name into the corresponding IP address of the web server, enabling their browsers to connect to it effectively. Other options like NTP (Network Time Protocol), STP (Spanning Tree Protocol), and API (Application Programming Interface) do not directly relate to providing access to a web server. NTP is used for clock synchronization, STP is concerned with network topology and preventing loops in switched networks, and APIs facilitate interactions between applications. Thus, modifying the DNS settings is essential for ensuring the web server can be accessed remotely through a domain name.
