問題 #55
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?

答案：D

解題說明：
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.

問題 #56
A financial company uses a remote access solution that directs all traffic over a secure tunnel. The company recently received some large ISP bills from the headquarter location. According to traffic analysis during the investigation, most of the network traffic was due to employees spending a lot of time on video conferences provided by a SaaS collaboration company. What must the company modify to reduce the cost without negatively impacting security or employee experience?

答案：A

解題說明：
In aFull TunnelVPN configuration, all traffic from the remote client is sent to the VPN headend before being routed to its final destination. This often results in "hairpinning," where high-bandwidth latency-sensitive traffic, such as video conferencing, travels to the corporate data center only to be sent back out to the internet, doubling the bandwidth consumption at the headquarter's ISP link.
To resolve this, the company should implementSplit-Excludetunneling. This configuration allows the VPN administrator to define specific applications or IP ranges-in this case, the SaaS video platform-that should bypass the secure tunnel and go directly to the internet via the user's local ISP. This significantly reduces the load on the corporate headquarter's internet connection and often improves the "employee experience" by reducing latency for the video stream. Unlike Option A, which degrades quality, or Option C/D, which disrupts workflow and security posture, split-excluding trusted SaaS traffic maintains a high security standard for internal resources while optimizing infrastructure costs. This aligns with theCisco SDSIobjective of designing scalable and cost-effective remote access solutions usingCisco Secure Client(AnyConnect) and Firepower Threat Defense (FTD) policies.

問題 #57
Which generative AI impact is addressed by a human-in-the-loop design policy?

答案：B

解題說明：
A human-in-the-loop design policy ensures that humans validate or oversee AI-generated outputs, reducing the risk of AI hallucinations (false or misleading information generated by AI).
This provides accountability and accuracy in generative AI use.


問題 #58
Which tool must be used to prioritize incidents by a SOC?

答案：B

解題說明：
A SIEM (Security Information and Event Management) tool collects and correlates security logs from across the enterprise, then applies analytics to prioritize incidents for SOC analysts. This enables efficient detection and response to the most critical threats.


問題 #59
A software development company uses multiple cloud providers to host applications. The company is designing a scalable firewall solution that must meet the requirements:
* Consistent security policies across multiple cloud environments.
* Centralized visibility and management.
* Scalability to accommodate different cloud platforms.
Which type of firewall meets the requirements?

答案：A

解題說明：
In a multi-cloud architecture, traditional perimeter-based firewalls often create "chokepoints" and fail to provide the granularity needed for east-west traffic between microservices across different providers. A distributed firewallis the architectural solution designed to meet these modern requirements. Unlike a centralized appliance, a distributed firewall is implemented as a software-defined layer that resides close to the workloads-often within the hypervisor or as part of a service mesh.
According to Cisco Security Infrastructure objectives, a distributed firewall allows forcentralized managementof a unified policy that is pushed out to all enforcement points, regardless of whether the workload is in AWS, Azure, or an on-premises data center. This ensuresconsistent security policiesacross the entire footprint. Because the enforcement is decentralized, the solution scales automatically as new cloud platforms or workloads are added. While aTraditional Firewall(Option A) lacks the multi-cloud agility, a Zone-based Firewall(Option B) is typically tied to specific physical or logical interfaces on a router, and a Host-based Firewall(Option D) is managed at the individual OS level, which becomes difficult to coordinate centrally at scale. The distributed firewall model aligns with theCisco SAFEarchitectural goal of pervasive security and simplified operations in highly dynamic, heterogeneous cloud environments.
