Question #81
During the deployment of the CrowdStrike Container Sensor in a Kubernetes cluster, the sensor fails to register with the CrowdStrike Falcon platform.
What could be the root cause of this issue?
- A . The sensor must be deployed as a DaemonSet with one pod per namespace.
- B . The sensor requires elevated privileges for all containers running in the cluster.
- C . The sensor requires a direct internet connection to the CrowdStrike cloud.
- D . The Kubernetes API server is not configured to allow external admission plugins.
Correct Answer: C
C
Explanation:
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.

Question #82
What is a key requirement for deploying the CrowdStrike Kubernetes Admission Controller to monitor and secure Kubernetes workloads?
- A . The Admission Controller requires the Mutating Admission Webhook configuration to be enabled in the Kubernetes API server.
- B . The Admission Controller must run with root-level permissions inside a privileged container.
- C . The Admission Controller requires a dedicated namespace in the Kubernetes cluster.
- D . The Admission Controller must be deployed as a DaemonSet on every node.
Correct Answer: A
A
Explanation:
Option A: The CrowdStrike Kubernetes Admission Controller uses the Mutating Admission Webhook to intercept and modify requests to the Kubernetes API server. This webhook allows the controller to enforce security policies and inject the required sensor configurations into pods at creation time. Ensuring the Mutating Admission Webhook configuration is enabled is a critical setup step for proper functionality.
Option B: The Admission Controller does not require root-level or privileged permissions. It relies on webhook functionality to perform its operations and does not interact directly with host-level resources.
Option C: While namespaces are often used for logical organization, the Admission Controller does not necessarily require a dedicated namespace. It can be deployed in any namespace, depending on the user’s configuration preferences.
Option D: The Admission Controller is not deployed as a DaemonSet; instead, it operates as a webhook server integrated with the Kubernetes API server. DaemonSets are typically used for agents that need to run on every node, such as logging or monitoring tools.

Question #84
What is the best approach to detect rogue containers and configuration drift in a Kubernetes environment?
- A . Enable admission controllers to prevent unauthorized deployments
- B . Use default Kubernetes logging mechanisms to detect all runtime anomalies
- C . Integrate CrowdStrike’s container runtime protection to monitor container activity
- D . Deploy static rules to enforce container security policies
Correct Answer: C
C
Explanation:
Option A: Admission controllers are effective at preventing unauthorized deployments at the admission stage but do not monitor runtime behavior. They cannot detect rogue containers that bypass admission controls or identify configuration drift after deployment.
Option B: Kubernetes logging mechanisms provide a baseline for auditing but lack the specificity and advanced threat detection capabilities needed to identify rogue containers and configuration drift effectively.
Option C: CrowdStrike’s container runtime protection provides real-time monitoring of container activity, detecting rogue containers and runtime configuration drift. This approach uses behavioral analysis and IOA detection to identify threats that static policies cannot handle.
Option D: Static rules enforce predefined security configurations but are inflexible in identifying runtime anomalies or dynamic threats. They do not adapt to changes in the runtime environment and can miss rogue containers or configuration drift.
