Cisco Designing Cisco Security Infrastructure Sample Questions (Q57-Q62):

NEW QUESTION # 57
Which financial reporting regulatory framework must a publicly traded company doing business in the US comply with?

Answer: A

Explanation:
Publicly traded companies in the United States must comply with the Sarbanes-Oxley Act (SOX).
This regulation mandates strict standards for financial reporting, internal controls, and data integrity to protect investors from fraudulent financial practices.


NEW QUESTION # 58
A retail company is facing a series of cyberattacks targeting the web servers, which results in disruptions to the online services. Upon investigation, the security team identified that these attacks involved invalid HTTP request headers, which were used to exploit vulnerabilities in the web application. To safeguard the company websites against similar threats in the future, the security team must deploy a security solution specifically designed to detect and block such malicious web traffic. Which security product must be used to protect the websites from similar attacks?

Answer: C

Explanation:
A Web Application Firewall (WAF) is specifically designed to protect web servers and applications against attacks such as malformed HTTP requests, invalid headers, and injection attempts. By inspecting HTTP traffic, it blocks malicious requests before they reach the application, safeguarding the company's websites from similar disruptions.


NEW QUESTION # 59
Which tool is used by a SOC analyst to quarantine an endpoint?

Answer: C

Explanation:
In the event of a confirmed compromise, a SOC analyst must act quickly to prevent lateral movement.Cisco XDR (Extended Detection and Response)is the integrated security platform designed to provide cross- layered detection and automated response actions across the network, endpoint, and cloud. One of the most critical response actions within XDR is the ability toquarantine or isolate an endpoint.
Cisco XDR integrates with endpoint security agents (like Cisco Secure Client) and network infrastructure (like Cisco ISE). From a single interface, an analyst can trigger a "Host Isolation" command. This command instructs the endpoint agent to block all network traffic except for communication with the security console, effectively putting the device in digital quarantine. This is much faster and more effective than manually tracking down the device. Aflow collector(Option A) andsyslog(Option B) are diagnostic tools used for visibility and logging; they cannot take active enforcement actions. Aload balancer(Option C) manages traffic distribution for applications and is irrelevant to endpoint containment. Cisco XDR fulfills the SDSI objective of "Securing Infrastructure through Automation," allowing SOC teams to mitigate threats at scale through coordinated response workflows.

NEW QUESTION # 60
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 headcounter 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?

Answer: C

Explanation:
Split-exclusion allows trusted SaaS traffic (such as video conferencing) to bypass the VPN tunnel while keeping all other traffic secured. This reduces bandwidth costs at the headend location without degrading security or employee experience, since traffic to the SaaS provider is still encrypted natively.


NEW QUESTION # 61
Considering recent cybersecurity threats, a company wants to improve the process for identifying, assessing, and managing risks with a comprehensive and holistic approach. Which framework must be used to meet these requirements?

Answer: C

Explanation:
NIST SP 800-37 provides the Risk Management Framework (RMF), which establishes a structured process for identifying, assessing, and managing cybersecurity risks. It offers a comprehensive and holistic approach, integrating security and risk management activities into the system development life cycle, making it the appropriate framework for this requirement.


NEW QUESTION # 62
