NEW QUESTION # 65
An employee of a pharmaceutical company accidentally checked in code that contains AWS secret keys to a public GitHub repository, which exposes production resources to attackers.
Which mitigation strategy must a security engineer recommend to prevent future reoccurrence?
Answer: D
Explanation:
An SCM (Source Code Management) precommit hook scans code for sensitive information such as AWS keys before it is committed. This prevents developers from accidentally pushing secrets to public repositories, protecting production resources from exposure.
NEW QUESTION # 66
The network security team of a private university is conducting a comprehensive audit to evaluate the security posture across the network infrastructure. During the review, the security team found that a trusted vendor disclosed serious vulnerabilities identified in a product that plays a crucial role in the university's CI/CD pipeline. The security team must act promptly to mitigate the potential risks posed by these vulnerabilities.
Which action must the security team take first in response to the disclosure?
Answer: B
Explanation:
According to theCisco Security Incident Responselifecycle and theNIST SP 800-61standards referenced in the SDSI objectives, the very first step in responding to a third-party vulnerability disclosure isIdentification and Validation. Before a team can patch, notify stakeholders, or monitor for exploits, they must perform an asset inventory check to confirm whether the specific vulnerable version of the product is actually running within their environment.
In a complex CI/CD pipeline, multiple tools and versions coexist. Jumping straight to patching (Option D) without validation can lead to unnecessary downtime or "breaking" integrated workflows if the vulnerability doesn't actually apply to the version in use. Similarly, using an IDS (Option A) is a detection/monitoring step that follows the confirmation of risk. Notifying customers (Option B) is a later phase in the incident response process, usually reserved for confirmed breaches or significant service impacts. By confirming the presence and version of the software first, the security team can accurately assess theblast radiusand prioritize remediation efforts based on the actual risk to the university's specific infrastructure. This systematic approach ensures that resources are allocated efficiently and that the security posture is managed based on verified data rather than assumptions.

NEW QUESTION # 67
A financial company is in the process of upgrading network access across the entire company. The solution must ensure: least privilege access control access across different network segments and increased security for employees. Which solution approach must the company take?
Answer: A
Explanation:
In the architecture of a modern secure infrastructure, achievingleast privilegeis a foundational requirement, especially for a financial institution where data sensitivity is high.Role-Based Access Control (RBAC)is the specific methodology used to restrict network access based on the roles of individual users within an enterprise. By implementing RBAC, the security team can ensure that employees only have access to the specific network segments and resources necessary for their job functions, effectively minimizing the internal attack surface.
Within the Cisco Security ecosystem, RBAC is often operationalized through tools likeCisco Identity Services Engine (ISE)usingScalable Group Tags (SGTs). Instead of relying on static IP addresses or complex Access Control Lists (ACLs) that are difficult to maintain across different segments, RBAC allows for dynamic policy enforcement. For example, a "Financial Auditor" role would automatically be granted access to the accounting segment but blocked from the development segment, regardless of where they plug into the network. WhilePKI(Option C) provides strong authentication and encryption, andNetFlow(Option A) provides visibility, neither inherently defines the "least privilege" permission structure. RBAC is the architectural approach that directly maps business requirements to technical access policies, ensuring that security is maintained across segmented environments as required by the Cisco SDSI objectives for secure infrastructure design.

NEW QUESTION # 68
Refer to the exhibit. In addition to SSL decryption, which firewall feature allows malware to be blocked?
Answer: C
Explanation:
In the exhibit, SSL decryption is already enabled, which allows encrypted traffic to be inspected.
To block malware hidden within decrypted traffic, the next required feature is File Inspection. This function analyzes files passing through the firewall to detect and stop malicious content.
NEW QUESTION # 69
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: C
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.
