NEW QUESTION # 26
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 checks before being allowed to access the network. Which action achieves the level of security and control?
Answer: C
Explanation:
In high-security environments like banking, simply verifying a user's identity is insufficient; the "health" or security state of the device must also be validated.Posture validation, implemented throughCisco Identity Services Engine (ISE), is the specific architectural process used to ensure an endpoint meets the organization's security requirements-such as having an active antivirus, the latest OS patches, or disk encryption enabled-before it is granted access to the internal network.
When an endpoint connects, Cisco ISE triggers a posture check (often via the Cisco Secure Client agent). If the device is found to be non-compliant (e.g., outdated signatures), ISE can move the endpoint into a restricted quarantineVLAN where it can only access remediation servers to update its software. Only after a successful re-scan shows the device is compliant is the network access policy updated to allow full internal connectivity.
This effectively prevents compromised or "dirty" endpoints from spreading threats laterally across the bank's network. WhileMFA(Option A) secures the user's identity andTrustSec(Option B) provides segmentation, only Posture validation addresses the technical compliance of the endpoint hardware and software itself.Data Loss Prevention(Option C) is focused on data transit rather than initial network admission control.

NEW QUESTION # 27
A software development company relies on GitHub for managing the source code and is committed to maintaining application security. The company must ensure that known software vulnerabilities are not introduced to the application. The company needs a capability within GitHub that can analyze semantic versioning and flag any software components that pose security risks. Which GitHub feature must be used?
Answer: D
Explanation:
In modern DevSecOps, managing third-party dependencies is a major security challenge.Dependabot(often stylized as Depend-a-bot) is the specific GitHub feature designed to automate the identification and updating of vulnerable dependencies. It works by scanning the application's manifest files (like package.json or requirements.txt) and analyzing thesemantic versioningof the included libraries.
When a known vulnerability (CVE) is reported in a specific version of a library used by the application, Dependabot flags the security risk and alerts the development team. Most importantly, it can automatically generate pull requests to upgrade the dependency to the minimum secure version that resolves the vulnerability. This ensures that the application remains secure without requiring manual tracking of every third-party component.
WhileGitHub Actions(Option C) can be used to run security scanners (like SAST tools), it is a general automation framework, not a dedicated dependency analysis tool.Artifact attestations(Option D) are used to prove the provenance and integrity of a build, andSealed boxes(Option B) is not a standard GitHub security feature related to vulnerability scanning. Utilizing Dependabot directly supports the Cisco SDSI objective of
"Securing the CI/CD pipeline" by proactively managing the Software Bill of Materials (SBOM) and ensuring that vulnerable components do not reach the production environment.
NEW QUESTION # 28
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: A
Explanation:
In a smart factory environment, IoT devices often use specialized industrial protocols (like Modbus, PROFINET, or EtherNet/IP) and have limited built-in security. To meet the requirements of protecting these devices from network-based attacks while gaining visibility into communication patterns and detecting anomalies, anIPS/IDS (Intrusion Prevention/Detection System)is the most effective solution.
Modern Cisco Secure Firewall (NGFW) systems integrate advanced IPS/IDS capabilities that go beyond simple port-based filtering. They provide deep packet inspection (DPI) to identify specific IoT protocols and baseline "normal" behavior. When an IoT device suddenly begins communicating with an unknown external IP or attempts to use a command it has never used before, the IPS/IDS can trigger an alert or block the traffic as an anomaly.
While aZone-Based Firewall(Option A) or aTraditional Firewall(Option C) can segment traffic and control access between zones, they generally lack the granular visibility and behavior-based anomaly detection required for IoT security. ATransparent Firewall(Option B) is a deployment mode that makes the firewall
"invisible" at Layer 2, which is useful for insertion into existing networks but does not inherently provide the required anomaly detection. Therefore, IPS/IDS is the primary technology within the Cisco Security Infrastructure that addresses the need for signature-based protection combined with behavioral visibility for specialized IoT traffic.

NEW QUESTION # 29
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:
Cilium is a Kubernetes Container Network Interface (CNI) that provides scalability, cloud-native security with eBPF-based enforcement, and strong visibility/observability into network traffic between microservices. It is purpose-built to modernize applications running in Kubernetes clusters.
NEW QUESTION # 30
What does watermarking AI generated content prevent?
Answer: A
Explanation:
In the realm of Artificial Intelligence and DevSecOps,watermarkingis a critical security technique used to identify the origin of synthetic media. As generative AI models become increasingly sophisticated, they can create highly realistic images, videos, and audio clips-often referred to asdeep fakes. These deep fakes pose a significant risk to organizational security and public trust, as they can be used for sophisticated social engineering attacks, such as impersonating executives in "Business Email Compromise" (BEC) scenarios or spreading misinformation.
By embedding a cryptographic or perceptible watermark into AI-generated content, security systems and users can verify the authenticity and provenance of the media. This proactive measure helps prevent the successful deployment of deep fakes by making it easier for automated security tools to flag synthetic content that lacks a valid "signature" of origin. While watermarking does not inherently stop the creation ofharmful content(Option C) or reduceresource consumption(Option A), it provides a layer of accountability and verification. Similarly,scale changes(Option D) are technical image manipulations that watermarking does not prevent. Within the Cisco SDSI framework, watermarking is viewed as an essential component of the AI security lifecycle, ensuring that generative technologies are used responsibly and that synthetic content is distinguishable from genuine data.
