NEW QUESTION # 33
A security engineer on an application design team must choose a framework of attack patterns to evaluate during threat modeling. Which framework provides the common set of attacks?
Answer: B
Explanation:
In the "Risk, Events, and Requirements" domain of the Cisco SDSI curriculum, understanding how to systematically identify and mitigate threats is essential.MITRE CAPEC (Common Attack Pattern Enumeration and Classification)is a comprehensive dictionary and classification scheme for known attack patterns used by adversaries. It is specifically designed to help security engineers, developers, and designers understand how an attacker might exploit a system. By using CAPEC during the threat modeling phase, an engineer can look at specific "attack patterns"-such as SQL injection, Cross-Site Scripting (XSS), or Man-in- the-Middle-to see if the application's architecture is resilient against them.
UnlikeCisco SAFE(Option A), which is an architectural guide providing best practices for designing secure networks, orGDPR(Option B) andSOC2(Option D), which are regulatory and compliance frameworks focused on privacy and operational auditing, CAPEC is purely technical and focused on the "how" of an attack. It provides the granular data necessary to simulate attacks and build robust defenses into the application design. Integrating CAPEC into the development lifecycle allows teams to move beyond broad risks and address the specific methods attackers use to bypass security controls. This alignment with the MITRE knowledge base ensures that the security infrastructure is designed with a realistic understanding of modern adversarial tactics, which is a core objective for Cisco security professionals.
NEW QUESTION # 34
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: B
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 # 35
How is generative AI used in securing networks?
Answer: B
Explanation:
The integration ofArtificial Intelligence (AI)andGenerative AI (GenAI)into network security is a pivotal component of theCisco SDSI v1.0blueprint. While traditional security mechanisms rely on deterministic rules and static signatures, GenAI leverages large-scale telemetry data to understand the baseline behavior of a specific network environment. By processing vast amounts of flow logs, packet metadata, and user activity, AI models candetect unusual patterns-often referred to as anomalies-that signify sophisticated threats such as zero-day exploits, lateral movement, or slow-and-low data exfiltration.
In a modern security architecture, GenAI enhances the "Visibility and Monitoring" domain by identifying deviations that would be invisible to human analysts. For instance, if an application suddenly changes its communication frequency or connects to a previously unknown internal segment, the AI can flag this as a potential compromise. Unlike Option A or B, which focus on operational efficiency and performance, or Option C, which is a reporting and compliance function, the use of AI forbehavioral analyticsdirectly strengthens the threat detection lifecycle. Cisco products likeSecure Network Analytics(Stealthwatch) and Cognitive Intelligenceuse these AI capabilities to transition from reactive defense to a proactive posture, reducing the window of opportunity for attackers and aligning with the Cisco SAFE principle of continuous monitoring and pervasive visibility.

NEW QUESTION # 36
How does a SOC leverage flow collectors?
Answer: C
Explanation:
A flow collector gathers metadata about network traffic (such as NetFlow or IPFIX), which SOC analysts use to analyze communication patterns. This data is critical for threat detection and response, helping identify anomalies, lateral movement, or potential attacks.
NEW QUESTION # 37
A manufacturing company recently experienced a network-down scenario due to malware spread on the management network. The company wants to implement a solution to detect and mitigate a similar threat in the future and protect the overall network. Which solution meets the requirements?
Answer: B
Explanation:
The spread of malware across a sensitive segment like themanagement networkhighlights a failure in host- level security and internal visibility. To detect and mitigate the spread of such threats and protect the overall network,Endpoint Detection and Response (EDR)is the most effective choice among the options. In the Cisco security ecosystem, the endpoint is often the last line of defense and the most critical source of telemetry for malware incidents.
By deploying an EDR solution likeCisco Secure Endpoint, the manufacturing company gains the ability to identify the "patient zero" of the infection. EDR uses advanced features likeDevice TraversalandLateral Movementdetection to see how malware moves from one machine to another over the management network.
Once detected, the security team can use the EDR platform to initiate a "host isolation" command, effectively cutting off the infected device's communication with the rest of the network without physically unplugging it.
WhileEncrypted Threat Analytics (ETA)(Option C) is a powerful network-based feature for detecting malware in encrypted traffic without decryption, EDR provides the most granular control and response capabilities specifically for malwareresiding on and spreading betweenhosts. RADIUS (Option B) and IPsec VPNs (Option D) focus on access control and encryption of data in transit, respectively, but do not provide the behavioral analysis needed to stop a running malware outbreak once the network has already been accessed.
