質問 # 56
A global marketing firm, based in California with customers on every continent, suffered a data breach that exposed employee and customer PII. Which regulations is the company in danger of violating?
正解：A
質問 # 57
In preparation for an upcoming security audit, a metal production company decided to enhance the security of container-based services running in a Kubernetes environment. The company wants to ensure that all communications between applications and services are encrypted. The administrator plans to implement mTLS service between application and services to secure the data exchanges. Given the need to manage encryption at scale and maintain efficient communication across the cluster, which network transport technology must be employed?
正解：A
解説：
In modern cloud-native architectures, managing security for hundreds of microservices manually is unfeasible. To implementmutual TLS (mTLS)at scale within a Kubernetes cluster, aService Mesh(such as Istio or Cisco Service Mesh Manager) is the architectural solution of choice. A service mesh provides a dedicated infrastructure layer for handling service-to-service communication without requiring changes to the application code itself.
The service mesh operates by deploying a "sidecar" proxy alongside every service instance. These proxies handle the heavy lifting of identity verification, certificate rotation, and the establishment of encrypted tunnels. This ensures that every data exchange is encrypted and that services only communicate with authenticated peers. While anIngress Controller(Option A) manages traffic entering the cluster andLoad Balancing(Option B) distributes traffic, neither provides the granular, internal encryption framework required for pod-to-pod mTLS.Kubernetes Network Policies(Option C) act as a distributed firewall to allow or deny traffic based on IP/Port but do not handle encryption or cryptographic identity. By choosing a Service Mesh, the company satisfies the audit requirement for end-to-end encryption and pervasive visibility into the application's communication flow, aligning with Cisco's design principles for secure, scalable microservices.

質問 # 58
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 check before being allowed to access the network. Which action achieves the level of security and control?
正解：D
解説：
Posture validation with Cisco ISE checks endpoint compliance (such as antivirus status, patches, and security configurations) before granting network access. This ensures compromised or non- compliant endpoints are denied access, directly addressing the bank's security concern.
質問 # 59
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?
正解：B
解説：
To secure both wired and wireless access points against unauthorized devices, the industry-standard framework isIEEE 802.1x. This technology provides port-based network access control (PNAC), ensuring that no traffic-wired or wireless-is forwarded by the switch or access point until the device or user has been successfully authenticated by a central authority, typically a RADIUS server likeCisco Identity Services Engine (ISE).
In an 802.1x architecture, the device (Supplicant) must provide valid credentials or certificates to the switch
/AP (Authenticator). The Authenticator then communicates with the Authentication Server to verify the identity. If authentication fails, the port remains in a "closed" state, effectively preventing the unauthorized
"rogue" wired connections mentioned in the scenario. This approach is far more scalable and dynamic than manually shutting down ports or usingVACLs(Option C), which are static filters based on IP or MAC addresses.VxLANs(Option A) are used for network virtualization and overlay tunneling, whilePrivate VLANs(Option B) provide Layer 2 isolation within a subnet but do not verify identity. By implementing
802.1x, the construction company establishes a robust "gatekeeper" at the hardware level, satisfying the Cisco SDSI objective of securing the network edge through identity-based access control for a diverse set of devices.

質問 # 60
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?
正解：A
解説：
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.
