Question No.42
HOTSPOT
You are designing an AI solution that will be used to find buildings in aerial pictures.
Users will upload the pictures to an Azure Storage account. A separate JSON document will contain for the pictures.
The solution must meet the following requirements:
Store metadata for the pictures in a data store.
Run a custom vision Azure Machine Learning module to identify the buildings in a picture and the position of the buildings#39; edges.
Run a custom mathematical module to calculate the dimensions of the buildings in a picture based on the metadata and data from the vision module.
You need to identify which Azure infrastructure services are used for each component of the AI workflow.
The solution must execute as quickly as possible.
What should you identify? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Correct Answer:
Question No.43
DRAG DROP
You are designing a solution that uses drones to monitor remote locations for anomalies. The drones have Azure loT Edge devices. The solution must meet the following requirements:
Email a user the picture and location of an anomaly when an anomaly is detected. Use a video stream to detect anomalies at the location.
Send the pictures and location information to Azure. Use the least amount of code possible.
You develop a custom vision Azure Machine Learning module to detect the anomalies.
Which service should you use for each requirement? To answer, drag the appropriate services to the correct requirements. Each service may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Correct Answer:
Question No.44
HOTSPOT
You are designing a solution that will ingest temperature data from loT devices, calculate the average temperature, and then take action based on the aggregated data. The solution must meet the following requirements:
Minimize the amount of uploaded data.
Take action based on the aggregated data as quickly as possible.
What should you include in the solution? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct Answer:
Question No.45

Question No.47
Your company has recently purchased and deployed 25,000 IoT devices.
You need to recommend a data analysis solution for the devices that meets the following requirements:
Each device must use its own credentials for identity.
Each device must be able to route data to multiple endpoints.
The solution must require the minimum amount of customized code. What should you include in the recommendation?
-
Microsoft Azure Notification Hubs
-
Microsoft Azure Event Hubs
-
Microsoft Azure IoT Hub
-
Microsoft Azure Service Bus
Correct Answer: C
Explanation:
An IoT hub has a default built-in endpoint. You can create custom endpoints to route messages to by linking other services in your subscription to the hub.
Individual devices connect using credentials stored in the IoT hub#39;s identity registry. References:

Question No.49
You have an Azure Machine Learning model that is deployed to a web service. You plan to publish the web service by using the name ml.contoso.com.
You need to recommend a solution to ensure that access to the web service is encrypted. Which three actions should you recommend? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
-
Generate a shared access signature (SAS)
-
Obtain an SSL certificate
-
Add a deployment slot
-
Update the web service
-
Update DNS
-
Create an Azure Key Vault
Correct Answer: BDE
Explanation:
The process of securing a new web service or an existing one is as follows:
-
Get a domain name.
-
Get a digital certificate.
-
Deploy or update the web service with the SSL setting enabled.
-
Update your DNS to point to the web service.
Note:
To deploy (or re-deploy) the service with SSL enabled, set the ssl_enabled parameter to True, wherever applicable. Set the ssl_certificate parameter to the value of the certificate file and the ssl_key to the value of the key file.
