This question evaluates your knowledge of IoT Security — a core concept tested in Microsoft Certified: Azure IoT Developer Specialty (AZ-220). Understanding IoT Security is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
You need to authenticate IoT devices to IoT Hub in a way that each device has a unique cryptographic credential and a compromised device credential can be revoked without affecting other devices. Which authentication method should you use?
Microsoft Defender for IoT has flagged anomalous communication patterns from one of your IoT Hub-connected devices. You need to investigate the device without disrupting the rest of your fleet. What is the fastest action to isolate the device?
You are provisioning a large fleet of low-cost sensors using DPS symmetric key attestation. What is the security best practice for managing the symmetric keys in the device firmware?
You are designing a high-security IoT device and must ensure its private keys are never exposed in system memory or storage. Which hardware component should you integrate, and how does the Azure IoT SDK support it?
