NEW QUESTION # 60
Which generative AI impact is addressed by a human-in-the-loop design policy?
Answer: D
Explanation:
In the realm of Artificial Intelligence security,AI hallucinationsoccur when a generative model perceives patterns that are non-existent or logically incorrect, leading to the creation of content that is nonsensical, factually wrong, or potentially dangerous. To mitigate the risks associated with these inaccuracies, ahuman- in-the-loop (HITL)design policy is essential. This policy ensures that human judgment and contextual understanding are integrated into the AI's decision-making or output validation process.
According to theCisco SDSI v1.0objectives, while AI is exceptional at processing high volumes of data, it lacks the ethical and logical framework to consistently identify its own hallucinations. By implementing a HITL approach, subject matter experts can review AI-generated responses, code, or security alerts before they are acted upon. This human oversight allows for the identification of "logical leaps" or false information that automated filters might miss.
Whiledeep fakes(Option B) are typically addressed through cryptographic watermarking or origin tracking, andphishing(Option C) is mitigated via email security gateways and user training, hallucinations are an inherent flaw in the model's predictive nature that requires manual verification.Scale changes(Option D) refer to technical image manipulations and are not a primary concern for HITL policies. Incorporating human feedback-often throughReinforcement Learning from Human Feedback (RLHF)-allows the security infrastructure to refine the model's accuracy over time, ensuring that generative outputs remain reliable, safe, and aligned with organizational standards.
NEW QUESTION # 61
An oil and gas company recently faced a security breach when an employee's notepad, which contained critical login credentials, was stolen. The incident led to unauthorized access to a user account, which posed a significant risk to sensitive company data and operations. The company wants to adopt a security measure that enhances user account protection. Which action must be taken to prevent breaches like this from happening in the future?
Answer: C
Explanation:
Multi-Factor Authentication (MFA) strengthens user account security by requiring additional verification factors beyond passwords, such as tokens or biometrics. Even if credentials are stolen, MFA prevents unauthorized access, directly addressing the breach scenario.
NEW QUESTION # 62
Employees in a healthcare organization could not access their devices when they returned to work after the weekend. The security team discovered that a threat actor had encrypted the devices. Which security solution would mitigate the risk in future?
Answer: C
Explanation:
In the scenario described, the healthcare organization fell victim to aransomware attack, where devices were encrypted to extort the organization. To mitigate such risks in the future,Endpoint Detection and Response (EDR)is the essential architectural component. According to the Cisco SDSI Secure Infrastructure domain, protecting endpoints requires more than just traditional antivirus; it necessitates a solution that provides deep visibility into file behavior and process execution.
A robust EDR solution, such asCisco Secure Endpoint, continuously monitors all activity on the device.
When ransomware attempts to initiate its encryption process, the EDR can detect the malicious behavioral pattern in real-time. It can then take automated actions, such as isolating the infected host from the network and "stopping" the encryption process before it spreads. Furthermore, Cisco's EDR providesretrospective security, allowing administrators to see how the malware arrived and which other devices it touched. While Option A (Password Policies) helps prevent credential theft and Option C (DLP) prevents data theft, they do not stop the technical process of disk encryption. Only EDR provides the necessary detection and automated response capabilities to handle modern file-less and polymorphic malware threats effectively. This aligns with the Cisco SAFE goal of securing the endpoint layer against advanced persistent threats (APTs) and ransomware variants.

NEW QUESTION # 63
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: A
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 # 64
A bank experienced challenges with compromised endpoints gaining access to the internal network. To enhance security, the bank wants to ensure that all endpoints are scanned for compliance checks before being allowed to access the network. Which action achieves the level of security and control?
Answer: C
Explanation:
In high-security environments like banking, simply verifying a user's identity is insufficient; the "health" or security state of the device must also be validated.Posture validation, implemented throughCisco Identity Services Engine (ISE), is the specific architectural process used to ensure an endpoint meets the organization's security requirements-such as having an active antivirus, the latest OS patches, or disk encryption enabled-before it is granted access to the internal network.
When an endpoint connects, Cisco ISE triggers a posture check (often via the Cisco Secure Client agent). If the device is found to be non-compliant (e.g., outdated signatures), ISE can move the endpoint into a restricted quarantineVLAN where it can only access remediation servers to update its software. Only after a successful re-scan shows the device is compliant is the network access policy updated to allow full internal connectivity.
This effectively prevents compromised or "dirty" endpoints from spreading threats laterally across the bank's network. WhileMFA(Option A) secures the user's identity andTrustSec(Option B) provides segmentation, only Posture validation addresses the technical compliance of the endpoint hardware and software itself.Data Loss Prevention(Option C) is focused on data transit rather than initial network admission control.
