A) Create different set of Groups
B) You will obtain an endorsement key
C) You will obtain an enrollment key
D) You will allocate key to TPM policy
Correct
B -> You will obtain enrollment key
A device enrollment creates a record of a single device or a group of devices that may at some point register with the Azure IoT Hub Device Provisioning Service. The enrollment record contains the initial desired configuration for the device(s) as part of that enrollment, including the desired IoT hub. This article shows you how to manage device enrollments for your provisioning service.
An Enrollment group is an entry for a group of devices that share a common attestation mechanism of X.509 certificates, signed by the same signing certificate, which can be the root certificate or the intermediate certificate, used to produce device certificate on physical device. We recommend using an enrollment group for a large number of devices which share a desired initial configuration, or for devices all going to the same tenant. Note that you can only enroll devices that use the X.509 attestation mechanism as enrollment groups.
You can create an enrollment group in the portal for a group of devices using the following steps:
Log in to the Azure portal and click All resources from the left-hand menu.
Click the Device Provisioning service you want to enroll your device to from the list of resources.
In your provisioning service:

We recommend using an enrollment group for a large number of devices which share a desired initial configuration, or for devices all going to the same tenant. Note that you can only enroll devices that use the X.509 attestation mechanism as enrollment groups.
You can create an enrollment group in the portal for a group of devices using the following steps:
Log in to the Azure portal and click All resources from the left-hand menu.
Click the Device Provisioning service you want to enroll your device to from the list of resources.
In your provisioning service:
a. Click Manage enrollments, then select the Enrollment Groups tab.
b. Click the Add button at the top.
c. When the “Add Enrollment Group” panel appears, enter the information for the enrollment list entry. Group name is required. Also select “CA or Intermediate” for Certificate type, and upload the root Primary certificate for the group of devices.
d. Click Save. On successful creation of your enrollment group, you should see the group name appear under the Enrollment Groups tab. https://docs.microsoft.com/en-us/azure/iot-dps/how-to-manage-enrollments

A device enrollment creates a record of a single device or a group of devices that may at some point register with the Azure IoT Hub Device Provisioning Service. The enrollment record contains the initial desired configuration for the device(s) as part of that enrollment, including the desired IoT hub.

Question 33 of 50
33. Question
You uses Azure IoT Hub and you are creating devices under hub DigitalHUB. You need to make use that independently verifies devices with verified authentication credential can connect to DigitalHUB , which authentication type should you choose ?
A) Pass Through Authentication
B) Password Hash sync
C) X.509 CA signed
D) X.509 Self signed
E) X.509 Globally signed
Correct
Correct : C
The X.509 certificate-based security in the IoT Hub requires you to start with an X.509 certificate chain, which includes the root certificate as well as any intermediate certificates up until the leaf certificate.
You may choose any of the following ways to get your certificates:
Purchase X.509 certificates from a root certificate authority (CA). This method is recommended for production environments.
Create your own X.509 certificates using a third-party tool such as OpenSSL. This technique is fine for test and development purposes. See Managing test CA certificates for samples and tutorials for information about generating test CA certificates using PowerShell or Bash. The rest of this tutorial uses test CA certificates generated by following the instructions in Managing test CA certificates for samples and tutorials.
Generate an X.509 intermediate CA certificate signed by an existing root CA certificate and upload it to the hub. Once the intermediate certificate is uploaded and verified, as instructed below, it can be used in the place of a root CA certificate mentioned below. Tools like OpenSSL (openssl req and openssl ca) can be used to generate and sign an intermediate CA certificate. https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-security-x509-get-started

You have an existing Azure IoT hub.You use IoT Hub jobs to schedule long running tasks on connected devices. Which three operations do the IoT Hub jobs support directly?
A. Trigger Azure functions.
B. Invoke direct methods.
C. Update desired properties.
D. Send cloud-to-device messages.
E. Disable IoT device registry entries.
F. Update tags.
Correct
B,C, F
Azure IoT Hub enables a number of building blocks like device twin properties and tags and direct methods. Typically, back-end apps enable device administrators and operators to update and interact with IoT devices in bulk and at a scheduled time. Jobs execute device twin updates and direct methods against a set of devices at a scheduled time. For example, an operator would use a back-end app that initiates and tracks a job to reboot a set of devices in building 43 and floor 3 at a time that would not be disruptive to the operations of the building.
Note
The features described in this article are available only in the standard tier of IoT Hub. For more information about the basic and standard/free IoT Hub tiers, see Choose the right IoT Hub tier.
Consider using jobs when you need to schedule and track progress any of the following activities on a set of devices:
Update desired properties
Update tags
Invoke direct methods https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-jobs
