Cisco Designing Cisco Security Infrastructure Sample Questions (Q33-Q38):

NEW QUESTION # 33
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: D

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 # 34
A video game company identified a potential threat of a SYN flood attack, which could disrupt the online gaming services and impact user experience. The attack can overwhelm network resources by exploiting the TCP handshake process, leading to server unavailability and degraded performance. To safeguard the company's infrastructure and ensure uninterrupted service, it is essential to enhance the security measures in place. The company must implement a solution that manages and mitigates the risk of such network-based attacks. Which security product must be implemented to mitigate similar risks?

Answer: C

Explanation:
A SYN flood attack is a type of DoS/DDoS attack targeting the TCP handshake process. The correct mitigation is deploying a Cisco Secure Firewall, which includes advanced intrusion prevention, SYN flood protection, and traffic management capabilities to prevent resource exhaustion and keep services available.


NEW QUESTION # 35
How does AI improve the performance of intrusion prevention systems (IPS)?

Answer: C

Explanation:
AI enables IPS platforms to analyze traffic patterns in real time and dynamically create or adjust rules to respond to new and evolving threats.


NEW QUESTION # 36
Which generative AI impact is addressed by a human-in-the-loop design policy?

Answer: C


NEW QUESTION # 37
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: A

Explanation:
In a Kubernetes environment,Namespacesprovide a logical partition for resources but do not, by default, provide network isolation. To prevent "app01" from communicating with "app02," aNetworkPolicymust be implemented. NetworkPolicies act as the Layer 3/4 distributed firewall for the cluster, allowing administrators to define explicit rules for ingress and egress traffic between pods and namespaces.
To achieve complete isolation, a common design pattern is to implement a "deny-all" default policy for each namespace and then explicitly allow only necessary traffic. This aligns with theCisco SAFEarchitectural principle of micro-segmentation. WhileRoleBinding(Option B) manages permissions for the Kubernetes API (who can create or delete pods), it does not control the actual network traffic between those pods.HTTPRoute (Option A) andGateway(Option D) are components of the Kubernetes Gateway API used for managing external traffic routing and load balancing, rather than internal pod-to-pod isolation. By deploying NetworkPolicies, the administrator ensures that the "blast radius" of a compromised application is contained within its own namespace, fulfilling a core objective of securing cloud-native application infrastructure.
