NEW QUESTION # 86
You enable Azure Security Center for IoT.
You need to onboard a device to Azure Security Center. What should you do?
- A. Modify the connection string of the device.
- B. Install an X.509 certificate on the hardware security module (HSM) of the device.
- C. Add the azureiotsecurity module identity to the Azure IoT Hub device identity.
- D. Open incoming TCP port 8883 on the device.
Answer: C
Explanation:
Use the following workflow to deploy and test your Azure Security Center for IoT security agents:
1. Enable Azure Security Center for IoT service to your IoT Hub
2. If your IoT Hub has no registered devices, Register a new device.
3. Create an azureiotsecurity security module for your devices.
Azure Security Center for IoT makes use of the module twin mechanism and maintains a security module twin named azureiotsecurity for each of your devices.
Note: To manually create a new azureiotsecurity module twin for a device use the following instructions:
1. In your IoT Hub, locate and select the device you wish to create a security module twin for.
2. Click on your device, and then on Add module identity.
3. In the Module Identity Name field, enter azureiotsecurity.
4. Click Save.

NEW QUESTION # 96
You have 10,000 IoT devices that connect to an Azure IoT hub. The devices do not support over-the-air (OTA) updates.
You need to decommission 1,000 devices. The solution must prevent connections and autoenrollment for the decommissioned devices.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Blacklist the X.509 root certification authority (CA) certificate for the enrollment group.
- B. Delete the device identity from the device registry of the IoT hub.
- C. Remove the identity certificate from the hardware security module (HSM) of the devices.
- D. Update the connectionState device twin property on all the devices.
- E. Delete the enrollment entry for the devices.
Answer: A,E
Explanation:
Explanation
B: X.509 certificates are typically arranged in a certificate chain of trust. If a certificate at any stage in a chain becomes compromised, trust is broken. The certificate must be blacklisted to prevent Device Provisioning Service from provisioning devices downstream in any chain that contains that certificate.
C: Individual enrollments apply to a single device and can use either X.509 certificates or SAS tokens (in a real or virtual TPM) as the attestation mechanism. (Devices that use SAS tokens as their attestation mechanism can be provisioned only through an individual enrollment.) To blacklist a device that has an individual enrollment, you can either disable or delete its enrollment entry.

NEW QUESTION # 97
You have an Azure IoT Central solution that includes multiple IoT devices. The devices report temperature, humidity, and pressure.
You need to export the sensor data captured during a 48-hour period as a CSV file.
What should you use in IoT Central?
- A. Device groups
- B. Jobs
- C. Devices
- D. Analytics
Answer: D
Explanation:
Azure IoT Central provides rich analytics capabilities to analyze historical trends and correlate telemetry from your devices. To get started, select Analytics on the left pane.
The analytics user interface has three main components:
Data configuration panel: On the configuration panel, select the device group for which you want to analyze the data. Next, select the telemetry that you want to analyze and select the aggregation method for each telemetry. The Group By control helps to group the data by using device properties as dimensions.
Time control: Use the time control to select the duration for which you want to analyze the data.
Chart control: The chart control visualizes the data as a line chart.

NEW QUESTION # 98
You have an Azure Stream Analytics job that connects to an Azure IoT hub named Hub1445 as a streamingdata source. Hub1445 is configured as shown in the exhibit. (Click the Exhibit tab.)
The Stream Analytics job fails to receive any messages from the IoT hub. What should you do to resolve the issue?
- A. Enable the Route3 route.
- B. Change the Route1 route query to true.
- C. Disable the Route2 route.
- D. Enable the fallback route.
Answer: B
Explanation:
The device telemetry is usually passed as JSON from the device through the IoT Hub - this is handled nicely by Azure Streaming Analytics queries.
The IoT Hub message routing should be configured as follows: Data source: Device Telemetry Messages Routing query: true (as the routing query is an expression that evaluates to true or false for each received message, the simplest way to send all messages to the endpoint is to just supply true as the query).

NEW QUESTION # 103
You have three Azure IoT hubs named Hub1, Hub2, and Hub3, a Device Provisioning Service instance, and an IoT device named Device1.
Each IoT hub is deployed to a separate Azure region. Device enrollment uses the Lowest latency allocation policy.
The Device Provisioning Service uses the Lowest latency allocation policy. Device1 is auto-provisioned to Hub1 by using the Device Provisioning Service. Device1 regularly moves between regions.
You need to ensure that Device1 always connects to the IoT hub that has the lowest latency. What should you do?
- A. Disenroll and reenroll Device1.
- B. Configure device attestation that uses X.509 certificates.
- C. Configure the re-provisioning policy.
- D. Implement device certificate rolling.

You plan to deploy Azure Time Series Insights.
What should you create on iothub1 before you deploy Time Series Insights?
- A. a new consumer group
- B. a new message route
- C. a new shared access policy
- D. an IP filter rule
Answer: A
Explanation:
Create a dedicated consumer group in the IoT hub for the Time Series Insights environment to consume from. Each Time Series Insights event source must have its own dedicated consumer group that isn't shared with any other consumer. If multiple readers consume events from the same consumer group, all readers are likely to exhibit failures.
