Microsoft Azure IoT Developer — Question 19

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?

Answer options

• A. Azure API Management
• B. Azure Active Directory (Azure AD) Identity Protection
• C. Azure Defender for IoT
• D. an IP filter

Correct answer: D

Explanation

The correct solution is to configure an IP filter, which allows you to specify which devices can connect to the IoT hub based on their IP addresses. The other options do not directly limit connections to specific devices; Azure API Management is for managing APIs, Azure AD Identity Protection focuses on user identity security, and Azure Defender for IoT provides security for IoT devices but does not restrict access based on IP.
