What role does Zscaler serve as in DNS handling?

Zscaler acts as a DNS resolver, which means it is capable of translating domain names into IP addresses that computers use to identify each other on the network. This role is fundamental in web access since it allows users to navigate to websites using user-friendly domain names instead of having to remember numerical IP addresses.

In the context of Zscaler’s services, this DNS resolution capability enhances security and improves internet performance. Zscaler can provide threat intelligence during the resolution process, blocking requests to malicious domains, and enforcing security policies at the DNS level. Consequently, users benefit from both secure browsing and efficient DNS lookups, making Zscaler's role as a DNS resolver crucial to its overall architecture and functionality.

The other options do not accurately describe Zscaler's primary function in DNS handling. While Zscaler interacts with DNS requests and can forward them, its primary role and the essence of its service architecture is as a DNS resolver, integrating security features directly into the DNS resolution process.
