Answers
D.
It inspects outbound traffic content and blocks suspicious activity.
Suggested answer: D

Explanation:

CN-Series firewall prevents exfiltration by inspecting outbound traffic content and blocking suspicious activity. Exfiltration is a technique used by attackers to steal sensitive data or assets from a compromised network or system, usually by sending them to an external destination, such as a command and control server, a drop zone, or an email address. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CNSeries firewall prevents exfiltration by inspecting outbound traffic content and blocking suspicious activity using threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis. CN-Series firewall does not prevent exfiltration by employing custom-built signatures based on hash, distributing incoming virtual private cloud (VPC) traffic across the pool of VM-Series firewalls, or providing a license deactivation API key, as those are not valid or relevant methods for exfiltration prevention.
