Who is assigned to monitor network security, operation, and users?

• A. System Administrator
• B. Network Administrator
• C. IT Technician
• D. Security Analyst

Answer: (B)

Managing the network and who can access it is the job of the Network Administrator. This role is centered on the network itself—keeping the network up and running, watching for performance issues, configuring devices like routers and switches, and overseeing who can reach which resources. That includes managing user accounts and permissions on the network, enforcing access controls, and monitoring for unusual activity or security incidents at the network level.

Other roles handle different areas: a System Administrator tends to servers, operating systems, and applications; a Security Analyst focuses on detecting and analyzing threats and vulnerabilities; an IT Technician provides hands-on hardware and basic software support. For monitoring network security, operation, and users, the Network Administrator is the best fit.
