Q1. What does an Azure Resource Manager (ARM) template do?
- Automates Azure Service deployment
- Automates Visual Studio build validation
- Automates app distribution through PowerShell
Q2. What happens to telemetry data when a simulated alert is triggered?
- The simulator sends a property update to ADT, setting the Alert property to True, and begins polling ADT at a regular interval until the Alert property is set back to False.
- The simulator creates a trigger object in ADT, sets the Alert property to Sent, and immediately resumes sending telemetry data without waiting for a response.
- The simulator stops running the app on the mixed reality device until ADT sends back an Alert trigger confirmation, at which point telemetry data resumes.
Q3. What approach is the most efficient means to create assets in Unity that connect to ADT?
- Create one asset in the Scene and copy-paste it so that all parameters are transferred to the copy.
- Develop a ScriptableObject to create assets at runtime based on a core Prefab
- Drag and drop Prefab assets in the Scene
Q4. Which of the following real-time content use cases is the Azure SignalR service NOT a good fit for?
- High frequency data updates
- IoT and connected devices
- Local device data storage
