What does NIOS stand for?

• A. Network Identity Operating System
• B. Network Information Operating System
• C. Network Identity Oriented System
• D. Network Interface Operating System

Answer: (A)

Understanding acronym expansions for Infoblox products: NIOS stands for Network Identity Operating System. This matches Infoblox’s branding, where the operating system powers its DDI (DNS, DHCP, IPAM) appliances and manages network identity services across the infrastructure. The other options change key parts of the phrase—information vs. identity, oriented vs. operating, or interface vs. identity—that don’t align with how the product is named and described. So, Network Identity Operating System is the correct expansion.
