Question #1
You are troubleshooting a CrowdStrike Container Sensor deployment on a Kubernetes cluster. The sensor is not reporting data back to the CrowdStrike Falcon Console.
What could be the most likely cause of this issue?
- A . The CrowdStrike Container Sensor deployment does not include a valid CrowdStrike API token.
- B . The Kubernetes namespace for the sensor deployment was not labeled correctly.
- C . The Kubernetes cluster is using a version not supported by the CrowdStrike Container Sensor.
- D . The CrowdStrike Container Sensor Helm chart was not installed with elevated privileges.
Correct Answer: A
A
Explanation:
Option A: The CrowdStrike Container Sensor requires a valid API token for authentication and communication with the CrowdStrike Falcon Console. If the API token is invalid, expired, or missing, the sensor cannot register or send telemetry data. This is the most common issue when the sensor does not report data back.
Option B: Namespace labels are used for organizational purposes and are not directly tied to the sensor’s functionality. Incorrect labeling would not prevent data reporting.
Option C: While it is important to ensure compatibility, the CrowdStrike Container Sensor supports most modern Kubernetes versions. It is less likely to be the primary cause unless you are using a very outdated or experimental Kubernetes version.
Option D: The Helm chart installation requires proper permissions, but a lack of elevated privileges would typically cause the installation to fail entirely, not prevent the sensor from reporting data.

Question #2
During a container security audit, a security team finds that multiple Kubernetes pods are publicly accessible from the internet due to a misconfigured ingress rule.
Which of the following actions should the team take first to mitigate the risk?
- A . Modify the Kubernetes Ingress and NetworkPolicy rules to restrict public access only to necessary endpoints.
- B . Change the container runtime from Docker to containerd to improve security and reduce exposure
risks. - C . Shut down all affected pods immediately to prevent unauthorized access.
- D . Disable all public-facing networking in the cloud provider settings, blocking all traffic to the cluster.
Correct Answer: A
A
Explanation:
Option A: Misconfigured Kubernetes ingress rules can expose sensitive services to the internet. The correct action is to update Ingress and NetworkPolicy rules to limit access to only trusted sources and necessary endpoints, reducing exposure while maintaining functionality.
Option B: Changing the container runtime (e.g., Docker to containerd) can have security benefits, but it does not resolve misconfigured network exposure.
Option C: Shutting down pods immediately may prevent unauthorized access but could also cause operational disruptions. The correct approach is to first secure network access before considering pod restarts.
Option D: Disabling all public-facing networking is an extreme action that may impact legitimate services. The issue should be addressed through precise network policy adjustments rather than blanket restrictions.

Question #3
What is the primary purpose of registering cloud accounts in Falcon Cloud Security?
- A . To ensure that CrowdStrike can enforce runtime policies on all workloads within the registered account.
- B . To enable CrowdStrike to monitor and secure cloud accounts by integrating with their APIs.
- C . To allow CrowdStrike to automatically assign compliance scores to all resources in the account.
- D . To register an account so that CrowdStrike can block unauthorized users from accessing the cloud environment.
Correct Answer: B
B
Explanation:
Option A: CrowdStrike does not enforce runtime policies directly through account registration. Enforcement mechanisms require additional configurations like workload protection and agent deployment.
Option B: The primary purpose of registering a cloud account in Falcon Cloud Security is to enable integration via APIs. This integration allows Falcon Cloud Security to monitor, assess, and secure cloud resources across the account effectively.
Option C: While compliance monitoring is a feature enabled by account registration, the assignment of compliance scores is not automatic or the sole reason for registration. Additional configuration and
assessments are needed.
Option D: CrowdStrike does not block unauthorized access directly via cloud account registration. Access control relies on identity and access management (IAM) configurations and is outside the primary scope of CrowdStrike’s registration process.

Question #4
A security team using CrowdStrike Falcon Runtime Protection wants to detect and respond to Indicators of Attack (IOAs) in their containerized environment.
Which of the following is the best approach for detecting IOAs in real-time?
- A . Monitor system calls and process behaviors in runtime to detect anomalous activity indicative of an attack.
- B . Block all incoming network connections to containerized workloads to prevent potential attacks.
- C . Only analyze static container images for known vulnerabilities before deployment.
- D . Rely exclusively on Kubernetes audit logs to identify threats within the environment.
Correct Answer: A
A
Explanation:
Option A: CrowdStrike Falcon Runtime Protection detects Indicators of Attack (IOAs) by monitoring system calls, process behaviors, and runtime activities in containers. This allows Falcon to identify anomalous activity, privilege escalation attempts, and suspicious behaviors indicative of an attack.
Option B: Blocking all network traffic would break legitimate communications and is not a practical security measure. Instead, Falcon applies behavioral analytics to detect suspicious network activity dynamically.
Option C: Static analysis alone is insufficient for detecting IOAs, as runtime threats may emerge after deployment, including zero-day attacks and living-off-the-land techniques.
Option D: While Kubernetes audit logs provide useful insights, they do not capture all IOAs, particularly those at the process and system call level within containers.

Question #5
When configuring an automated remediation workflow for AWS findings in Falcon Fusion, why is it important to perform a dry run before enabling the workflow in production?
- A . To apply changes to a limited number of AWS resources for testing.
- B . To simulate the workflow actions without making changes to validate the logic and outcomes.
- C . To bypass the need for permissions validation during configuration.
- D . To generate a compliance report highlighting unresolved findings.
Correct Answer: B
B
Explanation:
Option A: Applying actual changes, even to a limited set of resources, does not constitute a dry run. A dry run explicitly avoids making changes to validate the workflow without risk.
Option B: A dry run simulates the actions of the remediation workflow without actually making any changes to the resources. This process is crucial for validating the workflow’s logic, ensuring it targets the intended findings, and understanding potential impacts. Dry runs help reduce the risk of unintended disruptions in production environments.
Option C: A dry run does not bypass permissions validation. In fact, testing permissions is an important part of the dry run process to ensure the workflow has the necessary access.
Option D: Generating compliance reports is not the purpose of a dry run. While useful for audits, compliance reports do not test the logic or simulate the outcomes of a workflow.

Question #6
A company has a Kubernetes-based container orchestration environment running on Amazon Elastic Kubernetes Service (EKS). The security team needs to ensure real-time visibility into container activities and implement runtime threat detection.
Which sensor should the team deploy to achieve these objectives?
- A . Falcon Kubernetes Sensor
- B . Falcon Host Sensor
- C . Falcon Cloud Workload Protection (CWP) Sensor
- D . Falcon Container Sensor
Correct Answer: D
D
Explanation:
Option A: This is not a valid CrowdStrike product. It may cause confusion due to the association with Kubernetes but does not exist as an offering.
Option B: The Falcon Host Sensor is designed for traditional workloads like virtual machines or physical servers. It does not natively integrate with containerized environments or provide detailed insights into container activities.
Option C: While Falcon CWP offers security for cloud-native workloads, it focuses on configuration assessment and vulnerability management rather than real-time runtime visibility for container activities. It is not specifically optimized for monitoring container behavior within Kubernetes environments.
Option D: The Falcon Container Sensor is specifically tailored for containerized environments, providing runtime protection, visibility, and threat detection. It integrates well with Kubernetes deployments, including Amazon EKS, making it the most appropriate choice in this scenario.

Question #7
Which of the following best describes the difference between managed and unmanaged items in the context of Falcon Cloud Security?
- A . Managed items are fully patched systems, while unmanaged items are systems that have pending updates.
- B . Managed items refer to accounts or containers with CrowdStrike agents installed, while unmanaged items lack such direct control.
- C . Managed items are actively assessed for vulnerabilities, while unmanaged items are not assessed at all.
- D . Managed items are those integrated into the Falcon platform, while unmanaged items are only monitored externally.
Correct Answer: B
B
Explanation:
Option A: The terms managed and unmanaged do not directly relate to the patching status of systems.
Both managed and unmanaged items could be fully patched or have pending updates.
Option B: Managed items refer to accounts or containers where CrowdStrike agents or direct integrations are applied, giving the Falcon platform control and visibility. Unmanaged items, by contrast, lack direct integration, meaning the platform can monitor them but not control them directly. This differentiation is critical for managing risks in hybrid environments.
Option C: Managed and unmanaged items are not defined by their vulnerability assessment status. Even unmanaged items can be assessed for risks through other tools or indirect integrations.
Option D: While managed items are integrated into the Falcon platform, unmanaged items are not merely "externally monitored." The key distinction lies in the presence or absence of direct CrowdStrike agent or integration.

Question #8
You are reviewing accounts using the CrowdStrike CIEM/Identity Analyzer and need to ensure MFA compliance.
Which account configuration demonstrates proper MFA implementation?
- A . An account with no login activity in the last 30 days and no additional authentication factors.
- B . An account that uses password authentication and an authenticator app for a one-time password (OTP).
- C . An account configured with biometric authentication only.
- D . An account that allows users to bypass additional authentication steps on trusted devices.
Correct Answer: B
B
Explanation:
Option A: The inactivity period and absence of additional authentication factors disqualify this account from demonstrating proper MFA implementation. This account would likely need further review for security compliance.
Option B: This setup meets the definition of MFA, combining two factors: "something you know" (password) and "something you have" (authenticator app). This ensures robust security against unauthorized access.
Option C: While biometric authentication ("something you are") is a strong factor, MFA requires combining at least two different factors. Biometric authentication alone does not meet this standard.
Option D: Allowing bypass of additional steps compromises the integrity of MFA and introduces vulnerabilities. Proper MFA should always require multiple factors, even on trusted devices.

Question #9
You are evaluating the asset inventory in a hybrid cloud environment monitored by CrowdStrike Falcon. An unregistered virtual machine (VM) in the cloud inventory is running outdated software with known vulnerabilities and accepting inbound connections from public IPs.
What is the best action to mitigate the risks associated with this asset?
- A . Deploy the Falcon sensor, restrict network access, and update the software on the VM.
- B . Assign the VM to a restricted group in the CrowdStrike platform.
- C . Ignore the VM until a breach is confirmed to avoid unnecessary disruptions.
- D . Terminate the VM immediately to prevent exploitation.
Correct Answer: A
A
Explanation:
Option A: Deploying the Falcon sensor ensures the VM is brought under management and monitoring.
Restricting network access limits exposure while updating the software addresses known vulnerabilities.
This approach effectively mitigates risk without unnecessarily disrupting operations.
Option B: While assigning the VM to a restricted group might help limit its access, it does not address the root cause of its vulnerabilities or the associated risks. Further actions, such as deploying the Falcon sensor and updating the software, are required.
Option C: Ignoring the VM leaves it vulnerable to exploitation, increasing the risk of a breach. Proactive steps are necessary to mitigate potential threats before they escalate.
Option D: Immediate termination could disrupt legitimate operations if the VM serves a business purpose. A more measured approach involves securing and updating the asset.

Question #10
What is the most effective action to take when a CIEM tool identifies an Azure Service Principal with overly permissive roles and no recent usage?
- A . Reassign the Service Principal to a new application for future use.
- B . Immediately delete the Service Principal to eliminate the risk.
- C . Assign a "Reader" role to the Service Principal to limit its permissions.
- D . Review and remove unnecessary roles or scope for the Service Principal.
Correct Answer: D
D
Explanation:
Option A: Reassigning the Service Principal does not address the risk of overly permissive roles. Additionally, using an existing Service Principal for a new purpose can create security challenges
Option B: While deleting the Service Principal may eliminate the risk, this approach can disrupt any active dependencies. A more controlled remediation involves first reviewing and adjusting permissions.
Option C: Changing the role to "Reader" may reduce risk, but it does not address whether the Service Principal is still necessary. The root cause (overly permissive roles and lack of usage) should be resolved.
Option D: The most effective action is to evaluate the necessity of the Service Principal and remove any unnecessary roles or scopes. This minimizes risk while maintaining operational functionality if needed.
