Question #12
CrowdStrike Falcon Cloud Workload Protection (CWP) offers runtime protection for containerized workloads.
Which feature or approach best helps identify unassessed images running in production?
- A . Image Scanning in Development Pipelines
- B . Runtime Inventory of Running Containers
- C . Integration with CI/CD for Build-Time Analysis
- D . Manual Configuration of Image Repositories
Correct Answer: B
B
Explanation:
Option A: This option refers to pre-deployment scanning of images in CI/CD pipelines. While important, it doesn’t address images that bypass these pipelines and are directly deployed to production without being assessed.
Option B: CrowdStrike Falcon provides runtime inventory capabilities, allowing users to identify and monitor container images currently running in production environments. This feature is critical for detecting unassessed or unverified images because it directly analyzes the live runtime environment, bypassing any gaps left during development or build phases.

Question #19
A security team has deployed a runtime protection sensor as a DaemonSet in a Kubernetes cluster. However, after deployment, the sensor fails to send security events to the central CrowdStrike Cloud. The cluster nodes show no network connectivity issues.
Which of the following is the most likely cause of the problem?
- A . The sensor is blocked by Kubernetes network policies; verify the namespace and allow necessary outbound traffic.
- B . The sensor DaemonSet is not using a privileged security context; restart with the –privileged flag enabled.
- C . The container runtime (e.g., containerd or CRI-O) is misconfigured; reinstall Kubernetes to ensure proper integration.
- D . The sensor lacks permissions to access container runtime data; check the Kubernetes RBAC settings.
Correct Answer: A
A
Explanation:
Option A: Kubernetes NetworkPolicies restrict outbound network traffic by default in some environments. If the namespace where the sensor runs has a restrictive policy, it could block egress traffic to the CrowdStrike Cloud, preventing event transmission.
Option B: While some security sensors may require privileged access, the issue described involves network connectivity, not container runtime access. Lack of privileges would cause failure in collecting logs rather than blocking outbound traffic.
Option C: Reinstalling Kubernetes is a drastic and unnecessary step. If the container runtime were misconfigured, containers might fail to start, but the problem described is event transmission failure, not container runtime issues.
Option D: RBAC misconfigurations could cause issues in accessing Kubernetes API resources, but they would not typically prevent event transmission to an external service.
