MARKETPLACE
Find Marketplace labs and courses in the portal Knowledgebase. Preview a published topology and its content details, then install an available lab into your own workspace to explore and configure.
Open KnowledgebaseBrowsing is public. Installing and accessing content may require sign-in, a suitable plan, or a separate content entitlement.
TUTORIALS
Work through guided configuration and troubleshooting tasks in the simulator. Read the instructions, make a change, and verify supported checkpoints against the state of your lab.
Guides and interactive checks depend on the published content. Some curriculum paths require earlier tutorials to be completed first.
EXAMINATIONS
Final assessments turn a lab into a practical skills check. Complete the assigned work, submit your attempt, and review your score and the course topics that need more practice.
No Final assessment was listed in the public catalog when checked on October 1, 2026. Availability depends on published content; access and attempt terms are shown with each assessment. These are nuLAB learning assessments.
IoT SIMULATIONS
Build a network of simulated sensors, actuators, and messaging infrastructure. Observe MQTT publishes and broker-to-subscriber deliveries directly on the topology.
Explore topics, subscriptions, and sensor values, then investigate how the network carries that telemetry between devices.
Discuss an IoT labIoT and industrial features require an eligible Enterprise plan. Device and protocol coverage varies by profile.
