질문 # 26
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?
정답：C
질문 # 27
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?
정답：B
설명：
In the realm of modern application security and Kubernetes networking,Ciliumhas emerged as the industry- standardContainer Network Interface (CNI)that leverageseBPF (extended Berkeley Packet Filter) technology. For a global company modernizing a monolithic app into microservices, Cilium provides the required scalability and high-performance networking by operating directly within the Linux kernel.
Unlike traditionalSecurity Groups(Option A) which are often limited to IP-based rules at the cloud infrastructure level, orENIs(Option C) which are AWS-specific hardware interfaces, Cilium providesidentity- awaresecurity. It understands Kubernetes labels and metadata, allowing for granular Layer 7 policy enforcement. Furthermore, Cilium addresses the "visibility and observability" requirement through itsHubble component, which provides deep insights into network flows, application dependencies, and security events without the overhead of traditional sidecar proxies. AnIngress Gateway(Option D) manages external traffic entering the cluster but does not provide the comprehensive pod-to-pod networking, eBPF-based security, or internal observability that a CNI like Cilium offers. Designing with Cilium aligns with Cisco's focus on cloud- native security and the use of eBPF for distributed firewalling and telemetry in modern application environments.

질문 # 28
A construction company recently introduced a BYOD policy, where contractors can bring personal devices and connect to the wireless network. The network engineer configured a Wi-Fi network with a guest splash page to provide internet access only. Although the policy was limited to wireless devices, contractors started bringing devices that needed wired connections without authorization and connecting to the network. The network team suggested shutting down ports where unauthorized devices are connected. Which technology must be implemented to ensure that wired and wireless devices are granted network access only after successful authentication?
정답：A
설명：
802.1X provides port-based network access control, requiring devices (wired or wireless) to authenticate before gaining network access. This ensures that only authorized users and devices can connect, enforcing the BYOD policy and preventing unauthorized wired connections.
질문 # 29
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?
정답：B
설명：
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.
질문 # 30
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?
정답：D
설명：
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.
