Which networks are supported by ISNS Services?

• A. Only NIPR networks
• B. NIPR, SIPR, and SCI networks
• C. Only SIPR networks
• D. Only SCI networks

Answer: (B)

ISNS Services are designed to work across the different DoD networks that handle information at various clearance levels. It supports NIPR networks, SIPR networks, and SCI networks, providing a consistent set of services to users regardless of the network they’re on as long as they have the necessary access. This cross-network capability is essential because personnel and systems often operate on different networks, and unified services reduce fragmentation and provisioning complexity. The other options that limit ISNS to a single network don’t reflect how ISNS is intended to function across the DoD to enable secure, cross-domain access.
