You need to protect the applications hosted on AKS1.

AKS workload protection is provided by Microsoft Defender for Containers. That plan covers Kubernetes posture, runtime threat detection, image risk signals, and container workload protections. Defender for Servers protects VMs and Arc servers, Defender for App Service protects web apps, Resource Manager protects control-plane operations, and Defender for Storage protects storage accounts. Because the applications are hosted on AKS1, Defender for Containers is the correct plan. The compute domain tests whether protection is applied before deployment, during runtime, or through posture assessment. The selected answer matches the phase described in the requirement. Detection-only tools are not acceptable when the requirement says prevent, and local installation methods are inferior when Defender for Cloud, Azure Policy, or Azure Machine Configuration can enforce the control centrally. The result is a direct exam-style implementation choice: it changes the required security behavior without relying on unrelated monitoring, manual cleanup, or excessive privilege.
