How does Google Cloud DNS function?

Google Cloud DNS primarily functions as a Domain Name System service. Its main task is to translate human-readable domain names (like www.example.com) into IP addresses that computers utilize to identify each other on the network. This translation process is vital for internet communication, as it allows users to type a simple URL instead of needing to remember complex numerical IP addresses.

When a user enters a domain name in their web browser, Google Cloud DNS quickly resolves this name to the associated IP address, enabling the browser to connect to the relevant server and load the requested web content. This functionality is essential for the accessibility of websites and services on the internet.

In contrast, other options relate to different functionalities: while data backups and web applications involve data storage and application hosting, respectively, they do not pertain directly to the core purpose of DNS. Likewise, securing network traffic is a function associated with various security protocols and cloud services but is not the role of a DNS service. By focusing on the translation aspect, Google Cloud DNS plays a crucial role in the infrastructure of the internet, facilitating the connection between users and online resources.
