Which role is primarily responsible for monitoring network activity and security?

• A. Network Administrator
• B. System Administrator
• C. Help Desk Technician
• D. Network Engineer

Answer: (A)

Understanding who monitors network activity and enforces security controls is essential. The Network Administrator is responsible for managing and maintaining network devices, watching traffic and performance, reviewing security logs, and applying firewall rules and access controls. This role keeps the network running smoothly while actively protecting it from threats.

System Administrators focus on servers, operating systems, and software, not primarily on network traffic monitoring. Help Desk Technicians handle user-facing issues and incident triage, not ongoing security monitoring. Network Engineers design and implement the network and may assist with monitoring, but the day-to-day task of watching activity and enforcing security is typically assigned to the Network Administrator.

So, the role that is primarily responsible for monitoring network activity and security is the Network Administrator.
