Which manages network traffic through network devices and services to protect key mission systems from unauthorized network activity?

• A. Network Management Operator (NMO)
• B. Endpoint Security Solution (ESS)
• C. Domain Name System (DNS)
• D. Cyber Command and Control Mission System (C3MS)

Answer: (A)

This item is testing who is responsible for directing how data moves across the network and applying security controls to keep key mission systems safe from unauthorized activity. The role that fits this best is the Network Management Operator, because this position focuses on overseeing the network’s devices and services—firewalls, routers, switches, IDS/IPS, VPNs, and monitoring tools—and ensuring security policies are enforced, traffic is properly filtered, and segments are protected. By coordinating how traffic traverses the network and responding to anomalies, the Network Management Operator helps prevent unauthorized access to critical systems. An endpoint security solution concentrates on protecting individual devices rather than the entire network path, so it can’t manage traffic flow across devices and services to guard whole mission systems. DNS handles domain name resolution, not network traffic protection. A Cyber Command and Control Mission System deals with high-level orchestration of cyber operations, not the day-to-day management of network traffic and security across the network infrastructure.
