312-50v13 Exam Dumps : Certified Ethical Hacker Exam (CEHv13)

The correct answer is B. In CEH ethical hacking and penetration-testing guidance, testers must operate strictly within the authorized scope, agreement, and reporting procedures. When sensitive data such as credit card numbers and PII is unexpectedly discovered, the tester should not copy, move, examine further, or continue testing as though it were a normal finding. CEH-aligned guidance specifically warns that when illegal or highly sensitive material is encountered, it should not be copied to the tester’s own device, and the tester must follow team guidance and remain within the engagement agreement. Continuing the test could increase exposure, disturb evidence, or violate PCI-DSS and privacy handling requirements. Making a local copy is especially wrong because it creates another unauthorized location for regulated data. Contacting the employee directly is also improper because escalation should go through the approved client point of contact or management. Therefore, the best course of action is to stop the test immediately and contact management.

The firewall described is doing more than simple header checks: it is validating session state and also performing some application-level analysis. That combination is characteristic of a Stateful Multilayer Inspection Firewall. This firewall type expands beyond traditional packet filtering by tracking the state of network connections (e.g., TCP handshake progression, established sessions, expected flags and sequence behavior) and applying inspection across multiple OSI layers. Because it understands whether traffic belongs to a legitimate, established session, it can block many spoofed or out-of-context packets that might pass a stateless filter.

The mention of being harder to bypass with fragmentation or tunneling attacks further supports this. Stateless packet-filtering firewalls mainly rely on source/destination IP, port, and protocol fields. Attackers may attempt fragmentation to split payloads across packets and evade simplistic inspection, or use tunneling to encapsulate traffic to hide prohibited content. A stateful multilayer firewall, by maintaining connection tables and reassembling or correlating traffic with session context, is better equipped to detect anomalies that do not align with valid session behavior and to apply deeper inspection policies.

Why the other choices are less fitting:

A Packet Filtering Firewall (A) focuses on basic header fields and is typically stateless, matching the opposite of what Mia observed.

An Application-Level Firewall (C) (proxy firewall) can do deep application inspection, but the scenario emphasizes a multilayer approach combining state tracking with application-level checks—more aligned with stateful multilayer inspection than a pure application proxy model.

A Circuit-Level Gateway Firewall (D) validates session establishment (e.g., TCP handshakes) and creates virtual circuits, but it generally does not perform meaningful application-level analysis of the content.

Therefore, the best match is B. Stateful Multilayer Inspection Firewall.

The correct answer is D. Detect.

The activity described is the continuous review of enterprise operational data to identify irregular patterns that may indicate malicious activity. This is a detection function.

CEH-aligned IDS material explains that intrusion detection systems monitor packets and attempt to discover whether an attacker is trying to break into a system or cause a denial-of-service condition. It also describes anomaly detection as measuring a baseline of activity, such as CPU utilization, disk activity, user logins, and file activity, so that abnormal behavior can be identified .

Option A. Predict is incorrect because prediction focuses on anticipating risks and likely threats before they occur.

Option B. Protect is incorrect because protection focuses on safeguards and controls that reduce the likelihood or impact of attacks.

Option C. Respond is incorrect because response occurs after an event or incident is detected.

Option D. Detect is correct because the team is monitoring data to identify suspicious or abnormal behavior.

Therefore, the best answer is D. Detect.
