Option A: This is incorrect because CrowdStrike does not use fallback public IPs to bypass restrictions. The exact IP addresses provided in the CrowdStrike Console must be allowlisted.
Option B: This is correct because failing to allowlist CrowdStrike IP addresses specifically affects the image assessment functionality. Other CrowdStrike services that do not rely on the registry allowlist may continue to operate normally.
Option C: This is incorrect because CrowdStrike does not have a fallback mechanism for IP detection in this context. The specified IP addresses must be explicitly allowlisted to enable image assessment.
Option D: This is incorrect because image assessment requires direct communication with the container registry. Without allowlisted IP addresses, the assessment will fail entirely, not operate with reduced capabilities.

According to CrowdStrike Falcon documentation regardingFalcon Cloud Security (FCS)andContainer Security, the method used to deploy sensors significantly impacts how updates are managed. When Linux hosts are part of a Kubernetes cluster and the Falcon sensor is deployed as aDaemonSet, the standard "Sensor Update Policy" configured in the Falcon Console does not automatically trigger a version change in the same way it does for a standard Windows or Linux workstation.
In aDaemonSet deployment, the sensor version is typically tied to the specificcontainer image tagor the version defined in theHelm chartor YAML manifest used during deployment. If the manifest specifies a static version or if the orchestration layer (Kubernetes) is not instructed to pull a newer image and rollout a restart of the DaemonSet pods, the hosts will remain on their current version regardless of the "n-2" policy set in the console.
Furthermore, CrowdStrike documentation notes that forLinux Sensor Update Policies, the "n-2" setting dictates which version isassignedto the host, but the mechanism of delivery must be supported. In containerized environments, the "Auto-update" feature is often bypassed by the immutable nature of the deployment. To resolve this, the administrator must update the DaemonSet configuration to point to the newer sensor image, allowing Kubernetes to perform a rolling update across the nodes.

Option A: Static analysis of container images is handled by tools like CrowdStrike Falcon Image Assessment, not the Falcon Container Sensor. The sensor focuses on runtime security within the deployed Kubernetes cluster.
Option B: Cluster scaling is not within the scope of the Falcon Container Sensor. Kubernetes handles scaling through mechanisms like Horizontal Pod Autoscaler or Cluster Autoscaler.
Option C: The Falcon Container Sensor is not a replacement for Kubernetes' logging and monitoring tools. It complements these tools by focusing on security aspects such as threat detection and runtime protection.
Option D: The Falcon Container Sensor provides runtime protection for containerized workloads, detecting threats, vulnerabilities, and anomalous behaviors in real time. This ensures that active workloads in a Kubernetes cluster are continuously monitored and secured against attacks.

Option A: The CrowdStrike Container Sensor is deployed as a DaemonSet to ensure it runs on all nodes, but it does not need a pod per namespace. This misunderstanding could lead to resource waste and unnecessary complexity.
Option B: The sensor itself requires elevated privileges to monitor workloads, but it does not enforce privilege elevation on all other containers in the cluster.
Option C: The CrowdStrike Container Sensor requires connectivity to the CrowdStrike Falcon cloud for registration, telemetry, and updates. Without a direct internet connection or a properly configured proxy, the sensor cannot communicate with the Falcon platform, leading to deployment failures. Ensuring network connectivity is one of the first troubleshooting steps.
Option D: While the Admission Controller relies on external admission plugins, the Container Sensor itself does not require this configuration. This is unrelated to sensor registration.
