Network Security Intermediate lab 2

A learner provisions an isolated network security environment and completes a guided operational task.

Business context

Ultiblob uses this exercise to train network security engineer candidates on realistic private-cloud lab operations rather than static videos.

Technical objective

Configure the core network security services, verify health, and record the result in the lab progress view.

Student instructions

  1. 1Open the lab workspace and review the topology map.
  2. 2Launch the required templates and wait for all provisioning checks to complete.
  3. 3Complete the configuration task in the course module.
  4. 4Run validation and capture the result for instructor review.
  5. 5Create a snapshot before any risky troubleshooting or failure exercise.

Troubleshooting

  • If access fails, confirm the bastion session is active and the instance is not expired.
  • If validation fails, inspect the lab event log before rerunning the check.
  • If configuration drifts, restore the latest clean snapshot and repeat the module task.

Cleanup

  • Export notes or reports required by the instructor.
  • Restore or delete temporary snapshots created during the exercise.
  • Use the teardown action when the module is complete or allow the TTL policy to expire the lab.
