Your next step: networking and network support

Project brief

 What the work can involve  Network support work can include documenting ports, checking connectivity, responding to faults and making approved configuration changes. Job titles and responsibilities vary. A certification can structure learning; it does not replace practice or guarantee employment. 
 Build a small evidence portfolio  Create a fictional small-office network with staff and guest VLANs, routing, DHCP and a management plan. Include a readable topology, an address table, sanitised configurations and tests of both allowed and blocked traffic. Explain why each major decision was made. 
 Add a fault report: the symptom, observations, hypotheses, the one change that fixed it and the checks afterwards. Keep the broken version and the corrected version separate. Someone reviewing the project should be able to reproduce the reasoning rather than only see a screenshot of a successful ping. 
 Skills to develop next  Practise communicating clearly, reading vendor documentation, basic Linux tools and version control. Learn change planning, rollback and escalation. Explore deeper switching, routing and wireless once the fundamentals feel comfortable. Use actual job descriptions in your area to choose the next specialisation, rather than collecting certificates without a project.

What I would improve next:

Do not include real passwords, personal data or private company configurations. No certification or job outcome is promised. Cloud projects begin on paper; check current charges and cleanup before creating provider resources.
