Microsoft Azure IoT Developer — Question 24

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 Defender for IoT
• B. Azure Active Directory (Azure AD) External Identities
• C. Azure Active Directory (Azure AD) Identity Protection
• D. an IP filter

Correct answer: D

Explanation

The correct answer is D, an IP filter, which allows you to restrict access to the IoT hub based on the IP addresses of Device1 and Device2. The other options do not provide the necessary control over device connections to the IoT hub, as they focus on security and identity management rather than specific device access control.
