D18912E1457D5D1DDCBD40AB3BF70D5D
Answer: A,B,D
Explanation:
Explanation
The Device Provisioning Service supports the following forms of attestation:
* X.509 certificates based on the standard X.509 certificate authentication flow.
* Trusted Platform Module (TPM) based on a nonce challenge, using the TPM 2.0 standard for keys to present a signed Shared Access Signature (SAS) token. This does not require a physical TPM on the device, but the service expects to attest using the endorsement key per the TPM spec.
* Symmetric Key based on shared access signature (SAS) Security tokens, which include a hashed signature and an embedded expiration.

Box 1: Protocol translation
In the protocol translation gateway pattern, only the IoT Edge gateway has an identity with IoT Hub. The translation module receives messages from downstream devices, translates them into a supported protocol, and then the IoT Edge device sends the messages on behalf of the downstream devices.
Box 2: Advanced MessageQueuing Protocol (AMQP)
Connection multiplexing - All devices connecting to IoT Hub through an IoT Edge gateway can use the same underlying connection. This multiplexing capability requires that the IoT Edge gateway uses AMQP as its upstream protocol.

NEW QUESTION # 112
You have an Azure IoT hub named Hub1 and a root certification authority (CA) named CA1. Hub1 is configured to use X.509 certificate device authentication.
You and a custom manufacturing partner complete a proof of possession flow.
You plan to deploy IoT devices manufactured by the custom manufacturing partner. Each device will have a certificate generated by an intermediate CA. The devices will authenticate by using device certificates signed by the partner.
You need to ensure that the custom devices can connect successfully to Hub1.
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:
Explanation
Graphical user interface, text, application, chat or text message Description automatically generated
Box 1: Sign the intermediate CA certificate by using the CA1 certificate.
X.509 certificates are typically arranged in a certificate chain of trust in which each certificate in the chain is signed by the private key of the next higher certificate, and so on, terminating in a self-signed root certificate.
This arrangement establishes a delegated chain of trust from the root certificate generated by a trusted root certificate authority (CA) down through each intermediate CA to the end-entity "leaf" certificate installed on a device.
Box 2: Sign the device certificate by using the intermediate CA
An intermediate certificate is an X.509 certificate, which has been signed by the root certificate (or by another intermediate certificate with the root certificate in its chain). The last intermediate certificate in a chain is used to sign the leaf certificate. An intermediate certificate can also be referred to as an intermediate CA certificate.
Box 3: Deploy the certificate chain to the device.
The leaf certificate, or end-entity certificate, identifies the certificate holder. It has the root certificate in its certificate chain as well as zero or more intermediate certificates. The leaf certificate is not used to sign any other certificates. It uniquely identifies the device to the provisioning service and is sometimes referred to as the device certificate. During authentication, the device uses the private key associated with this certificate to respond to a proof of possession challenge from the service.

NEW QUESTION # 114
You have an Azure subscription that contains an Azure IoT hub and two Azure IoT Edge devices named Device1 and Device2.
You need to ensure that the IoT hub only accepts connections from Device1 and Device2.
What should you configure?
- A. a private endpoint connection
- B. Azure Active Directory (Azure AD) Identity Protection
- C. a gateway device
- D. Azure API Management
Answer: A
Explanation:
Ingress connectivity to IoT Hub using Azure Private Link.
A private endpoint is a private IP address allocated inside a customer-owned VNet via which an Azure resource is reachable. Through Azure Private Link, you can set up a private endpoint for your IoT hub to allow services inside your VNet to reach IoT Hub without requiring traffic to be sent to IoT Hub's public endpoint. Similarly, your on-premises devices can use Virtual Private Network (VPN) or ExpressRoute peering to gain connectivity to your VNet and your IoT Hub (via its private endpoint). As a result, you can restrict or completely block off connectivity to your IoT hub's public endpoints by using IoT Hub IP filter or the public network access toggle. This approach keeps connectivity to your Hub using the private endpoint for devices.

NEW QUESTION # 115
You have 1,000 IoT devices that connect to an Azure IoT hub.
Each device has a property tag named city that is used to store the location of the device.
You need to update the properties on all the devices located at an office in the city of Seattle as quickly as possible. Any new devices in the Seattle office that are added to the IoT hub must receive the updated properties also.
What should you do?
- A. From Automatic Device Management, create an IoT device configuration.
- B. From the IoT hub, generate a query for the target devices.
- C. Create a scheduled job by using the IoT Hub service SDKs.
- D. Deploy an Azure IoT Edge transparent gateway to the Seattle office and deploy an Azure Stream Analytics edge job.
Answer: A
Explanation:
Automatic device management in Azure IoT Hub automates many of the repetitive and complex tasks of managing large device fleets. With automatic device management, you can target a set of devices based on their properties, define a desired configuration, and then let IoT Hub update the devices when they come into scope. This update is done using an automatic device configuration or automatic module configuration, which lets you summarize completion and compliance, handle merging and conflicts, and roll out configurations in a phased approach.
