Basic networking knowledge

Knows how networks work at a high level such as addressing, routing, ports and name resolution and states where a connection problem may arise.

How hrmforce measures this

Test of declarative job knowledge, usually assembled per client.

Level	Behaviour at this level
N1 Guided	Explains which parts make up a connection and performs a provided check such as a connectivity test. works under supervision and follows instruction · routine, one variable at a time · own task
N3 Proficient	Deduces from symptoms in which network layer a problem sits and supports that with own measurements. sets own approach and seeks input proactively · several variables, some ambiguity · own team or process
N5 Leading	Disseminates networking knowledge in the organisation, sets design principles and reviews network designs from suppliers. sets the standard and the policy · strategic, under high uncertainty · organisation, value chain or profession

N2 and N4 are deliberately not anchored. Raters place them between the anchors, following the O*NET convention.

These skills inherit the assessment route and the behavioural anchors of this construct.

K	Understanding routing and ports Routing · Ports	Explains how traffic finds its way through routes and ports and where a block can occur.	stable
V	Applying network segmentation Network segmentation · VLAN	Divides a network into separated zones with their own rules so an incident cannot spread freely.	rising

V	Setting up a VPN VPN	Sets up a secured connection for remote workers or sites and manages certificates and access rules.	stable
V	Managing a wifi network Wifi management	Manages wireless networks with channels, coverage, guest network and security and measures perceived speed.	stable
V	Performing network diagnostics Network troubleshooting	Diagnoses a connectivity problem with commands for ping, route tracing and name lookup and records the finding.	stable
T	Analysing network traffic Wireshark · Packet analysis	Captures traffic and reads the packets to determine which side of a connection causes the problem.	stable
