NEW QUESTION # 61
A manufacturing company experienced a security breach that resulted in sales data being compromised. An engineer participating in the investigation must identify who logged into the sales system during the affected period. Which approach must be used to gather the information?
Answer: B
Explanation:
AAA (Authentication, Authorization, and Accounting) provides accounting logs that record who logged in, when, and from where. During an investigation, these logs allow the security team to trace user logins to the sales system and identify who accessed it during the breach period.
NEW QUESTION # 62
Refer to the exhibit.
A software developer noticed that the application source code had been found on the internet. To avoid such an incident from happening again, the developer applied a DLP policy to prevent from uploading source code into generative AI tool like ChatGPT. When testing the policy, the developer noticed that it is still possible for the source code to be uploaded. Which action must the developer take to prevent this issue?
Answer: D
Explanation:
In the provided exhibit of theCisco Data Loss Prevention (DLP) Policyinterface (likely within Cisco Umbrella or a similar cloud security gateway), the reason for the policy's failure to stop the upload is clearly visible in the "Action" column. The rule named"ChatGPT Source Code"is currently configured with the action set toMonitor.
According to theCisco SDSI v1.0objectives regarding application and data security, theMonitoraction is designed for visibility and auditing. It allows the traffic to pass through while generating a log entry for security analysts to review. This is often used during an initial "discovery" phase to understand how data is moving without disrupting business processes. However, to fulfill the requirement ofpreventingthe unauthorized upload of sensitive data-such as application source code-the policy must be enforcement- centric.
By selectingOption D, the developer changes the action from "Monitor" toBlock. In "Block" mode, the DLP engine will actively intercept the web request to ChatGPT, inspect the content for "Source Code" classifications, and drop the connection if a match is found, thereby preventing the data from leaving the corporate environment. While moving rules (Option B) can resolve conflicts if a "Block" rule is superseded by an "Allow" rule higher in the list, the primary issue here is the non-restrictive action of the specific rule itself. Modifying data classifications (Option C) is unnecessary if the engine is already correctly identifying the source code, as evidenced by the successful monitoring logs mentioned in the scenario. Changing the action to Block is the definitive step to ensure data integrity and prevent intellectual property theft.
NEW QUESTION # 63
A company hosted multiple applications in the Kubernetes environment, using the naming app01, app02, and so on. An app01 user could access app02 data because no security measures are implemented. The administrator decided to place each application within a separate namespace and ensure that the namespaces are completely isolated and cannot communicate with each other. Which solution must be used to accomplish the task?
Answer: D
Explanation:
In Kubernetes, a NetworkPolicy controls communication between pods and namespaces. By applying policies that deny cross-namespace traffic, the administrator can ensure each application (e.g., app01, app02) is isolated and cannot access data from other namespaces.
NEW QUESTION # 64
A manufacturing company implemented IoT devices throughout their smart factory and needs a security solution that meets these requirements:
* Protect IoT devices from network-based attacks.
* Visibility into communication patterns.
* Anomaly detection for IoT traffic.
Which firewall technology or feature should be recommended?
Answer: C
Explanation:
In a smart factory environment, IoT devices often use specialized industrial protocols (like Modbus, PROFINET, or EtherNet/IP) and have limited built-in security. To meet the requirements of protecting these devices from network-based attacks while gaining visibility into communication patterns and detecting anomalies, anIPS/IDS (Intrusion Prevention/Detection System)is the most effective solution.
Modern Cisco Secure Firewall (NGFW) systems integrate advanced IPS/IDS capabilities that go beyond simple port-based filtering. They provide deep packet inspection (DPI) to identify specific IoT protocols and baseline "normal" behavior. When an IoT device suddenly begins communicating with an unknown external IP or attempts to use a command it has never used before, the IPS/IDS can trigger an alert or block the traffic as an anomaly.
While aZone-Based Firewall(Option A) or aTraditional Firewall(Option C) can segment traffic and control access between zones, they generally lack the granular visibility and behavior-based anomaly detection required for IoT security. ATransparent Firewall(Option B) is a deployment mode that makes the firewall
"invisible" at Layer 2, which is useful for insertion into existing networks but does not inherently provide the required anomaly detection. Therefore, IPS/IDS is the primary technology within the Cisco Security Infrastructure that addresses the need for signature-based protection combined with behavioral visibility for specialized IoT traffic.

NEW QUESTION # 65
Which two controls help detect drift in IaC-managed infrastructure? (Choose two.)
Answer: B,D
Explanation:
Continuous configuration monitoring detects deviations from IaC definitions, while immutable infrastructure minimizes drift by replacing resources instead of modifying them in place.
