Learners will understand network management functions and the tools and technologies required to manage networks. They will develop skills in interrogating a network to identify network assets and configure and carry out routine network management activities.
Understand network management tools and technologies.
Network technologies: operating systems, protocols, layout, devices.
Networking operating systems: examples e.g. Windows, Linux.
Networking protocols: e.g. SNMPv3, ICMP.
Layout: cabling, topologies, wireless.
Network devices: servers, workstations, interconnection devices, network cards, vendor specific hardware.
Networking tools: purpose e.g. fault management, performance management, specific examples of tools e.g. HP Openview, Cisco Works, Wireshark, using system software e.g. to find network assets.
Emerging technologies: e.g. more automated networks, AI and machine learning (autonomous networks), optical networking, cognitive radio, 5G, Wi-Fi 6 (802.11ax), SD-WAN standard.
Impact of emerging technologies: enhanced capabilities e.g. faster, greater storage capacity, improved control, new work methods e.g. mobile working, home working, web centric applications, ease of use.
Explain network technologies and tools.
Evaluate the impact of emerging network technologies.
Understand network management functions.
Network management functions: configuration, fault management, account management, performance variables e.g. network throughput, user response times, line utilisation.
Other activities: planning, designing, installing, network operations e.g. security, data logging, checking performance and traffic, reporting.
Explain the functions of network management.
Explain routine network performance management activities.
Be able to carry out network management activities.
Regular maintenance activities: e.g. backup and restore files, user account creation and deletion, design and develop login scripts, virus scans, file cleanup.
Tools: to manage performance or fault finding e.g. SNMP, HP Openview.
Documentation: work logs, log resources used, system testing.
Configuration options: user accounts location, choosing server and setting rights, drive mappings, virus scanning options.
Security features: VPN access, firewall management, access control lists, device hardening, continuous policy review, forensic analysis, user rights.
Security policies and procedures: periodically review user access and rights, penetration testing, security audits, review firewall and access control list policies.
Interrogate a network to identify the network assets and their configuration.
Carry out routine network management activities to meet requirements.
Keep accurate records of network management tasks.
Design a network security policy for a small organisation.
