NEW QUESTION # 67
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?
Answer: A
Explanation:
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.

NEW QUESTION # 68
Which benefit does AI provide in network security?
Answer: A
Explanation:
AI in network security enhances threat detection and vulnerability identification by analyzing large volumes of traffic and encryption patterns. It can automatically detect risks such as weak TLS algorithm usage, which would otherwise be difficult to identify quickly with manual processes.
NEW QUESTION # 69
A legal services company wants to prevent remote employees from accessing personal email and social media accounts while using corporate laptops. Which security solution enforces the policy?
Answer: B
Explanation:
In the modern landscape of remote work, a legal services company must enforce acceptable use policies (AUP) regardless of where a corporate laptop is located.Cisco Umbrellais the ideal architectural solution for this requirement. Umbrella acts as a Secure Internet Gateway (SIG) that operates primarily at the DNS and web layer. When a remote employee attempts to access a personal email site or a social media platform, Umbrella intercepts the DNS request and checks it against the organization's defined security policy.
Cisco Umbrella provides granularContent Filteringcapabilities, allowing administrators to block entire categories of websites, such as "Social Networking" or "Webmail," with a single click. This enforcement happens at the edge-before a connection is even established to the malicious or unauthorized site-making it highly efficient for remote users who may not be connected to the corporate VPN. WhileCisco TrustSec (Option A) andRADIUS(Option B) are powerful for internal network segmentation and authentication, they do not inherently provide the URL/domain-based categorization required to block specific web content for remote clients. Anetwork monitoring tool(Option D) provides visibility but lacks the active enforcement mechanism to block traffic. Therefore, Cisco Umbrella is the specified technology in the SDSI objectives for cloud-delivered web security and policy enforcement for a distributed workforce.

NEW QUESTION # 70
A manufacturing company implemented IoT devices throughout their smart factory and needs a security solution that meets these requirements:
- Protect IoT devices from network-based attacks.
- Visibility into communication patterns.
- Anomaly detection for IoT traffic.
Which firewall technology or feature should be recommended?
Answer: D
Explanation:
An Intrusion Prevention/Detection System (IPS/IDS) provides visibility into IoT communication patterns, protects against network-based attacks, and uses anomaly detection to identify abnormal IoT traffic behaviors. This makes it the most effective solution for securing IoT devices in a smart factory.
NEW QUESTION # 71
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?
Answer: D
Explanation:
When moving security closer to the data, the endpoint becomes the final perimeter. Ahost-based firewallis a software component that runs directly on the endpoint's operating system (Windows, macOS, or Linux).
While the company already has Next-Generation Firewalls (NGFWs) at the network edge, those devices cannot protect endpoints from threats originating within the same local network segment (East-West traffic) or when the device is used outside the corporate office.
Implementing a host-based firewall provides a critical layer ofdefense-in-depth. It allows security administrators to enforce strict inbound and outbound traffic rules based on applications and services specific to that device. For example, it can prevent a compromised laptop from scanning other devices on a public Wi- Fi network. In the Cisco ecosystem, this is often achieved through theCisco Secure Client(AnyConnect) using theNetwork Visibility Module (NVM)or integrated endpoint security suites.
While aDistributed Firewall(Option C) is used for micro-segmentation within data centers/clouds and aWeb Application Firewall (WAF)(Option B) protects servers from web-based attacks, only a host-based firewall meets the requirement for traffic filtering directly on the diverse array of endpoint devices. This approach ensures that even if the network edge is bypassed, the individual host remains hardened against lateral movement and unauthorized communication.
