QUESTION NO: 1
You need to configure Stream Analytics to meet the POV requirements.
What are two ways to achieve the goal? Each Answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. Route telemetry to an Azure Blob storage custom endpoint, and then configure the Blob storage as a reference input for Stream Analytics.
B. Create an input in Stream Analytics that uses the built-in events endpoint of IoT Hub as the source.
C. From IoT Hub, create a custom event hub endpoint, and then configure the endpoint as an input to Stream Analytics.
D. Create a Stream Analytics module, and then deploy the module to all IoT Edge devices in the fleet.
Answer: B,C
Explanation:
QUESTION NO: 2
You have an instance of Azure Time Series Insights and an Azure IoT hub that receives streaming telemetry from IoT devices.
You need to configure Time Series Insights to receive telemetry from the devices.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Explanation:
Step 1: Create a dedicated consumer group..
Add a consumer group to your IoT hub.
Applications use consumer groups to pull data from Azure IoT Hub. To reliably read data from your
IoT hub, provide a dedicated consumer group that's used only by this Time Series Insights environment.
Step 2: Add a new Time Series Insights event source.
Add a new event source
Sign in to the Azure portal.
In the left menu, select All resources. Select your Time Series Insights environment.
Under Settings, select Event Sources, and then select Add.
In the New event source pane, for Event source name, enter a name that's unique to this Time Series
Insights environment. For example, enter event-stream.
Step 3: Configure the Time Series event source to connect to an existing IOT hub Step 4: For Source, select IoT Hub.
Step 5: Select a value for Import option:
If you already have an IoT hub in one of your subscriptions, select Use IoT Hub from available subscriptions. This option is the easiest approach.

QUESTION NO: 3
You have an Azure IoT solution that includes an Azure IoT hub.
You receive a root certification authority (CA) certificate from the security department at your company.
You need to configure the IoT hub to use the root CA certificate.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:

QUESTION NO: 4
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. Configure the re-provisioning policy.
B. Implement device certificate rolling.
C. Disenroll and reenroll Device1.
D. Configure device attestation that uses X.509 certificates.
Answer: A
Explanation:
Automated re-provisioning support.
Microsoft added first-class support for device re-provisioning which allows devices to be reassigned to a different IoT solution sometime after the initial solution assignment. Re-provisioning support is available in two options:
Factory reset, in which the device twin data for the new IoT hub is populated from the enrollment list instead of the old IoT hub. This is common for factory reset scenarios as well as leased device scenarios. Migration, in which device twin data is moved from the old IoT hub to the new IoT hub.
This is common for scenarios in which a device is moving between geographies.

QUESTION NO: 5
You have an Azure IoT hub that is being taken from prototype to production.
You plan to connect IoT devices to the IoT hub. The devices have hardware security modules (HSMs).
You need to use the most secure authentication method between the devices and the IoT hub.
Company policy prohibits the use of internally generated certificates.
Which authentication method should you use?
A. a symmetric key
B. An X.509 certificate signed by a root certification authority (CA).
C. an X.509 self-signed certificate
D. a certificate thumbprint
Answer: B
Explanation:
Purchase X.509 certificates from a root certificate authority (CA). This method is recommended for production environments.
The hardware security module, or HSM, is used for secure, hardware-based storage of device secrets, and is the most secure form of secret storage. Both X.509 certificates and SAS tokens can be stored in the HSM Reference:
