NEW QUESTION # 50
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have a Standard tier Azure IoT hub and a fleet of IoT devices.
The devices connect to the IoT hub by using either Message Queuing Telemetry Transport (MQTT) or Advanced Message Queuing Protocol (AMQP).
You need to send data to the IoT devices and each device must respond. Each device will require three minutes to process the data and respond.
Solution: You update the twin desired property and check the corresponding reported property.
Does this meet the goal?
- A. No
- B. Yes
Answer: B
Explanation:
IoT Hub provides three options for device apps to expose functionality to a back-end app:
* Twin's desired properties for long-running commands intended to put the device into a certain desired state.
For example, set the telemetry send interval to 30 minutes.
* Direct methods for communications that require immediate confirmation of the result. Direct methods are often used for interactive control of devices such as turning on a fan.
* Cloud-to-device messages for one-way notifications to the device app.

Box 1: createOptions
Every module has a settings property that contains the module image, an address for the container image in a container registry, and any createOptions to configure the image on startup.
Box 2: portbindings
Use the PortBindings setting in the HostConfig group of the Docker container create options to map the exposed port in the module to a port on the host device.
For example, if you exposed port 8080 inside the module and want to map that to port 80 of the host device, the create options in the template.json file would look like the following example:
"createOptions": {
"HostConfig": {
"PortBindings": {
"8080/tcp": [
{
"HostPort": "80"
}

NEW QUESTION # 52
You are troubleshooting an Azure IoT hub.
You discover that some telemetry messages are dropped before they reach downstream processing. You suspect that IoT Hub throttling is the root cause.
Which log in the Diagnostics settings of the IoT hub should you use to capture the throttling error events?
- A. Connections
- B. Routes
- C. DeviceTelemetry
- D. C2DCommands
Answer: C
Explanation:
Explanation
The device telemetry category tracks errors that occur at the IoT hub and are related to the telemetry pipeline.
This category includes errors that occur when sending telemetry events (such as throttling) and receiving telemetry events (such as unauthorized reader). This category cannot catch errors caused by code running on the device itself.
Note: The metric d2c.telemetry.ingress.sendThrottle is the number of throttling errors due to device throughput throttles.

What should you configure?
- A. a private endpoint connection
- B. a gateway device
- C. Azure API Management
- D. Azure Active Directory (Azure AD) Identity Protection
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.
