With this exam you will be tested your working knowledge for Az-220. Below is the outline of the exam which you will be tested

Le responsabilità di uno sviluppatore IoT di Azure includono la gestione della configurazione del ciclo di vita del dispositivo, configurazione, e manutenzione, utilizzando servizi cloud e altri strumenti. Implementi progetti per soluzioni Azure IoT, inclusa la topologia dei dispositivi device, connettività, debug, e sicurezza, così come soluzioni per gestire, tenere sotto controllo, e trasformare le pipeline di dati relative all'IoT. Distribuisci anche i componenti di Azure IoT Edge e configuri la rete dei dispositivi sul perimetro. Uno sviluppatore IoT di Azure collabora con ingegneri dei dati e altre parti interessate per garantire un'integrazione aziendale di successo. Un candidato per questo esame dovrebbe avere esperienza nell'implementazione dei servizi di Azure che formano una soluzione IoT, comprese le opzioni di archiviazione dei dati, analisi dei dati, elaborazione dati, and platform-as-aservice options. Questo ruolo dovrebbe anche essere in grado di riconoscere le impostazioni di configurazione del servizio Azure IoT all'interno della porzione di codice di una soluzione IoT ed eseguire attività di codifica IoT specifiche in almeno una lingua supportata da Azure, incluso C#, Nodo, C, o Python.
