質問 # 59
After a recent security breach, a financial company is reassessing their overall security posture and strategy to better protect sensitive data and resources. The company already\ deployed on- premises next-generation firewalls at the network edge for each branch location. Security measures must be enhanced at the endpoint level. The goal is to implement a solution that provides additional traffic filtering directly on endpoint devices, thereby offering another layer of defense against potential threats. Which technology must be implemented to meet the requirement?
正解：A
解説：
A host-based firewall runs directly on endpoint devices, providing traffic filtering and protection at the endpoint level. This adds another layer of defense beyond the network edge firewalls, ensuring threats are mitigated closer to where sensitive data resides.

Which generative AI impact is addressed by a human-in-the-loop design policy?
正解：A
解説：
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.

An administrator at a large university wants to ensure that the new employees have the right level of access when they are onboarded. The administrator asked the team to configure the cloud environment and ensure that new employees have the appropriate access based on their roles and responsibilities. Which technique must be recommended to ensure the right level of access?
正解：D
解説：
In a modern cloud and campus environment, managing the lifecycle of an identity is the cornerstone of a secure architecture.Identity and Access Management (IAM)is the comprehensive framework of policies and technologies that ensures the right individuals have the appropriate access to technology resources. According to the Cisco SDSI objectives, IAM is the primary mechanism used to transition from manual, error-prone onboarding to a policy-driven approach based onroles and responsibilities.
IAM solutions allow administrators to define digital identities and associate them with specific roles (Role- Based Access Control). When a new employee is onboarded, the IAM system automatically provisions access to the necessary cloud applications and data based on their department or job function. This ensures the principle ofleast privilegeis maintained from day one. WhileSecurity Groups(Option B) andNetwork Access Control Lists (ACLs)(Option D) are important technical controls for filtering traffic at the network layer, they do not manage the identity lifecycle or the complex mapping of users to application permissions. A VPN(Option C) provides a secure tunnel for remote access but does not definewhata user can do once they are inside the network. IAM provides the central control plane for identity-centric security, which is essential for a large university environment with high user turnover and diverse access requirements.

質問 # 62
A global energy company moved a monolithic application from the data center to public cloud.
Over time, the company added many capabilities to the application, and it is now difficult for the application team to scale it. The application owner decided to modernize the application by moving to a Kubernetes cluster. However, he wants to ensure that the new application architecture provides a container network interface that is scalable, offers options for cloud-native security, and helps with visibility and observability. Which solution must be used to accomplish the task?
正解：A
解説：
Cilium is a Kubernetes Container Network Interface (CNI) that provides scalability, cloud-native security with eBPF-based enforcement, and strong visibility/observability into network traffic between microservices. It is purpose-built to modernize applications running in Kubernetes clusters.
質問 # 63
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?
正解：A
解説：
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.
