Network Administrator responsibilities include?

• A. A hardware technician responsible for maintaining servers only
• B. A software developer who writes business apps
• C. A compliance officer auditing PCI requirements
• D. Personnel responsible for managing the network within an entity, including security, installations, upgrades, maintenance and activity monitoring

Answer: (D)

Managing the network within an entity, including security, installations, upgrades, maintenance and activity monitoring, is the responsibility of a Network Administrator. This role covers securing the network infrastructure (firewalls, routers, switches), applying patches and configuration changes, maintaining secure baseline configurations, and continuously monitoring network activity and logs to detect and respond to potential threats. This is exactly what’s needed to protect cardholder data and meet PCI DSS requirements that focus on keeping networks secure and those security controls up to date. The other roles described don’t fit because they focus on individual areas (hardware maintenance, software development, or auditing) rather than the ongoing, hands-on management of the network and its security.
