CrowdStrike Falcon Cloud Security performs agentless cloud security posture management (CSPM) by integrating directly with cloud service providers such as AWS, Microsoft Azure, and Google Cloud Platform using native APIs. This approach allows Falcon to continuously assess cloud configurations, permissions, networking, storage, and identity controls without deploying sensors or agents.

By default, CrowdStrike configures cloud account scans to runevery 4 hours. This scan frequency is designed to strike a balance between near-real-time visibility and efficient API usage across cloud providers. Cloud environments are highly dynamic, with frequent changes to configurations, IAM policies, and services. A four-hour scan interval ensures that new misconfigurations or risky changes—such as overly permissive roles, exposed storage, or insecure network rules—are identified quickly enough to reduce exposure time.

Scanning more frequently could introduce unnecessary API throttling or operational overhead, while less frequent scans could delay detection of critical security gaps. The four-hour interval is therefore CrowdStrike’s recommended default for maintaining continuous visibility while preserving cloud provider performance and stability.

This default interval can be adjusted in certain scenarios, but unless explicitly changed,every 4 hoursis the standard scan cadence applied to AWS, Azure, and GCP environments.

When using theFalcon Kubernetes Admission Controller, CrowdStrike allows administrators to precisely scope which Kubernetes assets are evaluated againstIndicators of Misconfiguration (IOMs)andImage Assessment policiesby usingboth namespaces and pod or service labels.

Namespaces provide a logical boundary within Kubernetes clusters, often representing environments such as dev, staging, or production. Labels add further granularity by identifying workloads based on application, team ownership, or deployment tier. By combining namespaces and labels, security teams can enforce policies with fine-grained control while minimizing unintended enforcement.

Using only namespaces or only labels limits flexibility and may lead to over- or under-enforcement. CrowdStrike documentation supports the combined approach as a best practice for scalable and precise policy enforcement in Kubernetes environments.

Therefore, the correct answer isNamespaces and Pod or Service labels.

When protecting a Kubernetes endpoint that hosts container workloadswith access to the Linux kernel, CrowdStrike recommends deploying theFalcon Sensor for Linux as a DaemonSet.

This deployment model installs the full Falcon Linux sensor on each Kubernetes worker node using a DaemonSet, ensuring one sensor runs per node. Because the sensor has kernel-level access, it provides deep visibility into system calls, process execution, network activity, and container behavior—delivering robust runtime protection.

TheFalcon Container Sensor for Linuxis used when kernel access is not available (for example, in managed or restricted environments). TheFalcon Operator Container Imagesimplifies lifecycle management but is not itself the sensor. Deploying the standard Falcon Sensor for Linux outside a DaemonSet would not scale correctly in Kubernetes.

Therefore, for Kubernetes environments with kernel access, the correct and CrowdStrike-recommended installation isFalcon Sensor for Linux deployed as a DaemonSet.

Unassessed images pose a security risk because theyexist in connected image registries but have not been evaluated for vulnerabilities. Even if they are not currently running, these images can be deployed at any time, potentially introducing critical vulnerabilities, secrets, or malware into production environments.

Falcon Cloud Security emphasizes proactive image assessment to ensure risks are identifiedbefore deployment. Unassessed images represent blind spots where vulnerabilities may go unnoticed until runtime, increasing exposure and response time.

Options describing actively running containers are incorrect because running workloads are typically assessed through runtime sensors. The primary concern with unassessed images is theirunknown risk posture prior to use.

Therefore, the correct answer isThey are in one of your connected image registries but have not been checked for vulnerabilities.

WhenAWS Systems Manager (SSM)is unavailable,Ansibleis the supported and recommended IT automation tool for generating an inventory of unmanaged workloads and deploying the Falcon sensor using1-click sensor deployment workflows.

CrowdStrike integrates with Ansible to enable discovery, inventory generation, and automated sensor installation across cloud and on-prem environments. Ansible’s agentless architecture makes it especially suitable when native cloud management services are unavailable or restricted.

Other tools listed—Jet, Rudder, and Puppet—are not natively integrated with Falcon’s 1-click deployment workflows for unmanaged workload discovery in cloud environments.

Therefore,Ansibleis the correct answer.

InCrowdStrike Falcon Cloud Security, IOAs are categorized usingMITRE ATT&CK-aligned tacticsto help analysts quickly identify attacker objectives. When investigating how a threat actor may havemaintained accessto cloud resources after an initial breach, the appropriate tactic to focus on isPersistence.

Persistence IOAs represent techniques such as creating backdoor IAM roles, modifying access policies, adding API keys, enabling long-lived credentials, or altering cloud configurations to survive reboots or credential rotation. Filtering the IOA dashboard byPersistenceisolates these behaviors, enabling faster root-cause analysis and remediation.

Other filters serve different investigative purposes. Execution focuses on initial code execution, Privilege Escalation highlights elevation of permissions, and Ransomware identifies encryption-related activity. None of these specifically address long-term access maintenance.

Therefore, filtering byPersistenceis the correct and most effective way to identify IOAs related to maintaining access within cloud environments.

When troubleshooting issues with cloud account registrations in CrowdStrike Falcon Cloud Security, thefirst stepshould be toverify the email verification process. Cloud account registration workflows rely on confirmation emails for validation, authorization, and completion of onboarding steps.

If verification emails are delayed, blocked, or misrouted due to email filtering, domain restrictions, or misconfigured mail settings, the registration process can appear to fail even though the underlying configuration is correct. Checking this process is non-disruptive and often resolves the issue quickly.

Resetting user passwords or disabling registration features are intrusive actions that should only be taken after basic validation steps are completed. CrowdStrike best practices emphasize starting with low-impact troubleshooting actions before making broader changes.

Therefore, confirming that users are receiving and completing verification emails is the correct and recommended first step.

When deploying theFalcon Kubernetes Admission Controller (KAC)using aHelm chart, access to CrowdStrike-hosted container images is required. These images are stored inCrowdStrike’s private container registry, which requires authentication.

To retrieve the Falcon KAC image, a validCrowdStrike API client key(client ID and secret) must be provided. This API credential allows Helm to authenticate to the Falcon registry and securely pull the required KAC image during deployment. Without valid API credentials, image retrieval fails, and the KAC deployment cannot complete successfully.

Other options listed do not satisfy this requirement. SENSOR_PLATFORM and FALCON_REGION are configuration parameters used during sensor installation but do not authenticate registry access. Docker itself is not sufficient, as authentication to the CrowdStrike registry is still required.

Therefore, anAPI client keyis mandatory to ensure successful retrieval of the Falcon KAC image during Helm-based deployment.

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.

In CrowdStrike Falcon Cloud Security, Cloud Groups are used to logically group container images so that policies, assessments, and controls can be applied consistently across workloads. When editing or defining a Cloud Group for container images, Falcon allows administrators to select specificimage propertiesto precisely target the desired scope.

The three supported image properties areRegistry, Repository, and Tag.

Registryidentifies where the container image is hosted, such as Amazon ECR, Azure Container Registry, or Docker Hub.

Repositorydefines the image namespace or project within the registry.

Tagspecifies the image version or variant (for example, latest, v1.2.3, or prod).

Using these three properties together enables highly granular targeting. For example, security teams can apply stricter policies only to production-tagged images from a specific registry and repository, while allowing more flexibility for development images.

Options that includeNameare incorrect because CrowdStrike does not use a standalone “image name” field when defining Cloud Group image criteria. Instead, image identity is derived from the combination of registry, repository, and tag.

Therefore, the correct and fully supported selection isRegistry, Repository, and Tag, which aligns with CrowdStrike Falcon Cloud Security configuration and documentation.
