Exam 300-745 Topic 2 Question 51 Discussion

In the provided exhibit of theCisco Secure Endpoint (formerly AMP for Endpoints)console, the "Activity Details" pane on the right side provides the specific reason why the malicious file was allowed to execute.
The log clearly states:"The file was not quarantined. In audit only mode."This indicates that while the system correctly identified the file (iodnxvg.exe) as malicious and categorized it with a threat name (W32.
DFC.MalParent), it took no preventative action because of the policy configuration.
In Cisco Secure Endpoint, policies can be set to different modes.Audit Modeis typically used during the initial deployment or testing phase to gain visibility into what would be blocked without actually disrupting business operations. In this mode, the connector logs events and alerts administrators but does not move the file to a secure quarantine area. To fulfill the requirement ofpreventingthe execution of malicious files, the security designer must change the policy from "Audit" to a protective mode, such asProtectorQuarantine.
This ensures that the engine actively intervenes when a threat signature or suspicious behavior is detected.
While the file is confirmed as malicious (negating Option A) and the system is clearly active and logging (negating Option C), the lack of enforcement is a direct result of the specific operational mode selected.
Option B is incorrect because, although network blocking is a feature, the primary failure here is at the file execution/quarantine layer. This scenario emphasizes the importance of moving from a visibility-centric posture to an enforcement-centric posture in a mature secure infrastructure design.
