Which of the following actions is NOT part of the function of a domain name system?

The function of the Domain Name System (DNS) involves several critical operations that facilitate the use of domain names across the internet. Among the options, completing health checks of resources is not a function associated with DNS.

DNS primarily serves to translate user-friendly domain names into IP addresses, allowing web browsers to load internet resources easily. This includes registering domain names, routing traffic to websites based on those names, and providing the necessary IP address when a URL is entered. Each of these actions is essential for the seamless operation of the internet, as they ensure that users can access the correct resources without needing to memorize complex numerical addresses.

In contrast, health checks are specific monitoring functions typically performed by different services or tools within cloud infrastructure and network management. These are aimed at ensuring that resources (like servers or applications) are operational and performing as expected, rather than being a part of the DNS's primary responsibilities. Therefore, the action of completing health checks of resources does not align with the core functions of the Domain Name System.
