Free Practice Questions for CrowdStrike CCCS-203b Exam

To secure an AWS Elastic Kubernetes Service (EKS) cluster running on Amazon Linux 2–based EC2 instanceswith container-level visibility, CrowdStrike Falcon documentation identifies theFalcon Container Sensor for Linuxas the correct solution. This sensor is part of Falcon Cloud Security and is purpose-built to protect Kubernetes and containerized workloads.

The Falcon Container Sensor for Linux is deployed as a container (commonly as a DaemonSet) on each Kubernetes worker node. It integrates with the underlying Linux kernel to observe container runtime activity while maintaining Kubernetes awareness. This allows CrowdStrike to deliver deep visibility into container processes, file system activity, network connections, and inter-container behavior—capabilities that are not available with host-only sensors.

TheFalcon Sensor for Linuxprotects the EC2 host operating system but does not provide container-aware telemetry or Kubernetes context. TheFalcon Kubernetes Admission Controlleris a pre-runtime control used to enforce image and deployment policies at admission time, not to provide runtime detection.Image Assessment at Runtimeis a feature for evaluating container images and is not a deployable sensor.

Because the requirement explicitly includesruntime protection and container-level visibility within EKS, the Falcon Container Sensor for Linux is the only option that fully satisfies these needs according to CrowdStrike Falcon Cloud Security architecture and documentation.

When configuring a new image registry connection for aprivately hosted container registryin CrowdStrike Falcon Cloud Security, the required and most critical action is toverify the token and secretused for authentication. Private registries require explicit credentials so Falcon can securely access and assess container images for vulnerabilities, malware, and misconfigurations.

CrowdStrike supports multiple private registry types (such as private Docker registries or cloud-native registries with restricted access). In all cases, Falcon relies on valid authentication credentials—typically a token, username/password, or service account secret—to pull image metadata and layers. If these credentials are incorrect, expired, or misconfigured, image assessment will fail even if the registry connection appears configured.

Other options may be relevant in specific environments but are not universally required at creation time. Registry URLs are validated during setup, and allowlisting IP addresses may be necessary only if strict network controls are in place. Secret expiration checks are a maintenance concern, not a mandatory creation step.

Therefore, the required action when creating a private registry connection is toverify the token and secret.

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.

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.

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.

When remediation capacity is limited,CrowdStrike Falcon Cloud Securityemphasizesrisk-based prioritizationfocused onactual exposurerather than theoretical severity alone.

Filtering vulnerabilities bycontainer running statusallows teams to identify which vulnerable images areactively running and exposed, particularly those that arepublic-facing. Remediating vulnerabilities in running containers first reduces real-world risk immediately, while dormant or unused images can be addressed later.

CVSS scores and CVE age do not account for exploit accessibility or operational exposure. Taking the business offline is impractical and unnecessary when targeted remediation can significantly reduce risk.

Therefore, the correct and CrowdStrike-aligned approach is tofilter by container running status, makingOption Dthe correct answer.

InCrowdStrike Falcon Cloud Security, theAccount Registrationsection is the authoritative location for monitoring thestatus of onboarded cloud accountsand identifyingdeployment or configuration issues.

FromCloud Security → Settings → Account Registration, security teams can view whether AWS, Azure, or GCP accounts are successfully connected, partially configured, or experiencing errors. This view highlights misconfigurations such as missing permissions, failed integrations, or incomplete setup steps that could prevent posture assessments or detections from functioning correctly.

Other settings areas serve different purposes: Automate focuses on remediation workflows, posture policies define compliance logic, and scan settings control assessment frequency. None provide direct visibility into onboarding health and deployment validation.

Therefore,Cloud security – Settings – Account registrationis the correct and verified answer.
