NEW QUESTION # 36
A company has been facing recurring issues with SQL injection vulnerabilities affecting the products, leading to significant disruptions for customers. To address the security concerns proactively, the company wants to integrate a tool into the CI/CD pipeline. The tool must be capable of identifying vulnerabilities such as SQL injection early in the development process, which allows developers to rectify issues before the code is deployed. Which solution must be implemented to meet the requirement?
Answer: A
Explanation:
In the framework of theDesigning Cisco Security Infrastructure (300-745 SDSI)curriculum, the "Shift- Left" security strategy is fundamental to modern DevSecOps. To identify vulnerabilities like SQL injection at the earliest possible stage-specifically before the code is even compiled or deployed-Static Application Security Testing (SAST)is the required solution. SAST tools analyze the application's source code, byte code, or binaries without actually executing the program.
By integrating SAST tools like Checkmarx or SonarQube into the CI/CD pipeline, the security team can automate the scanning of every code commit or pull request. These tools use sophisticated algorithms to trace data flows and identify dangerous patterns, such as user-controlled input being concatenated directly into SQL queries without proper sanitization or parameterization. This proactive approach allows developers to receive immediate feedback within their native workflow, enabling them to fix security flaws before they progress into later, more expensive stages of the development lifecycle.
In contrast,Dynamic Application Security Testing (DAST)(Option D) requires a running instance of the application and typically occurs much later in the pipeline, such as during the testing or staging phase. While DAST is excellent for finding runtime vulnerabilities, it does not meet the requirement of identifying issues
"early in the development process" as effectively as SAST.Build log observability tools(Option B) and workflow automation platforms(Option C) provide infrastructure and visibility but do not possess the specialized engine required to perform deep code analysis for application-layer vulnerabilities like SQL injection. Implementing SAST ensures that security is a foundational element of the code-writing phase, aligning with Cisco's vision for a secure, automated software supply chain.
NEW QUESTION # 37
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: C
Explanation:
A host-based firewall runs directly on endpoint devices, providing traffic filtering and protection at the endpoint level. This adds another layer of defense beyond the network edge firewalls, ensuring threats are mitigated closer to where sensitive data resides.
NEW QUESTION # 38
A manufacturing company recently experienced a network-down scenario due to malware spread on the management network. The company wants to implement a solution to detect and mitigate a similar threat in the future and protect the overall network. Which solution meets the requirements?
Answer: B
Explanation:
Endpoint Detection and Response (EDR) provides continuous monitoring, detection, and automated mitigation of malware at the endpoint level. By stopping threats before they spread across the management network, EDR protects the overall infrastructure from similar network- down scenarios in the future.
NEW QUESTION # 39
Network administrators at a medical facility cannot log in to network devices because of excessive resource consumption and high CPU utilization. The situation has led to delays in routine maintenance and troubleshooting, which affects overall network performance. An engineer must optimize the handling of traffic to reduce the impact and maintain consistent access and operational efficiency. Which approach must be implemented to meet the requirement?
Answer: A
Explanation:
The scenario described-where high CPU utilization prevents administrators from accessing device management interfaces-is a classic indication that the device'sControl Planeis being overwhelmed by malicious or malformed traffic (such as a DoS attack or a routing loop). To protect the "brains" of the network device,Control Plane Policing (CoPP)must be implemented.
CoPP allows an engineer to define filter and rate-limit policies specifically for traffic destined for the CPU.
By categorizing traffic into different classes (e.g., routing protocols, management traffic like SSH, and "catch- all" untrusted traffic), CoPP ensures that critical management and control traffic is prioritized while excessive or suspicious traffic is dropped before it can impact the device's performance. This maintainsoperational efficiencyeven during a traffic spike or attack. WhileAAA(Option B) handles authentication andRBAC (Option D) manages permissions once a user is logged in, neither can prevent the CPU exhaustion that blocks the login attempt in the first place.SNMP(Option C) is used for monitoring but does not provide active traffic policing. Within the Cisco SDSI framework, CoPP is a fundamental "Self-Defending Network" feature required to ensure the availability and resilience of the core infrastructure.

NEW QUESTION # 40
How is generative AI used in securing network?
Answer: C
Explanation:
Generative AI enhances network security by identifying anomalies in traffic patterns. It learns normal network behavior and flags deviations that may indicate threats, such as intrusions or data exfiltration attempts.
