Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Computer Network Support Specialists

Maintaining LCAC-100 network elements and data-transfer systems provides a foundation for diagnosing and resolving civilian network problems.

How to prepare: Build a small Windows Server or Linux network lab and document how you diagnose and resolve simulated connectivity faults.

What the civilian work involves
  • Identify the causes of networking problems, using diagnostic testing software and equipment.
  • Document network support activities.
  • Back up network data.
