Cisco Designing Cisco Security Infrastructure Sample Questions (Q22-Q27):

NEW QUESTION # 22
A retail company is facing a series of cyberattacks targeting web servers, which results in disruptions to 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: D

Explanation:
The cyberattacks described target theapplication layer (Layer 7), specifically exploiting vulnerabilities through malformed HTTP headers. AWeb Application Firewall (WAF)is the specialized security solution required to mitigate these threats. Unlike standard firewalls that inspect traffic at the network and transport layers (IPs and Ports), a WAF performs deep inspection of HTTP/HTTPS traffic.
A WAF-such as those integrated into theCisco Secure Firewallor cloud-native WAF services-understands the structure of web requests. It can identify and block sophisticated attacks like SQL injection, Cross-Site Scripting (XSS), and the specific "invalid HTTP request headers" mentioned in the scenario. By applying a set of rules (often based on the OWASP Top 10), the WAF filters out malicious requests before they reach the web server.Antivirus software(Option A) andHost-based firewalls(Option D) protect the server's operating system from malware and unauthorized connections but cannot inspect the logic of a web request. A Traditional Firewall(Option B) would simply see the traffic as "allowed" on Port 443 and pass it through.
Implementing a WAF is a critical architectural requirement in the Cisco SDSI "Applications" domain to protect customer-facing web services from exploitation.


NEW QUESTION # 23
A software development company uses multiple cloud providers to host applications. The company is designing a scalable firewall solution that must meet the requirements:
* Consistent security policies across multiple cloud environments.
* Centralized visibility and management.
* Scalability to accommodate different cloud platforms.
Which type of firewall meets the requirements?

Answer: B

Explanation:
In a multi-cloud architecture, traditional perimeter-based firewalls often create "chokepoints" and fail to provide the granularity needed for east-west traffic between microservices across different providers. A distributed firewallis the architectural solution designed to meet these modern requirements. Unlike a centralized appliance, a distributed firewall is implemented as a software-defined layer that resides close to the workloads-often within the hypervisor or as part of a service mesh.
According to Cisco Security Infrastructure objectives, a distributed firewall allows forcentralized managementof a unified policy that is pushed out to all enforcement points, regardless of whether the workload is in AWS, Azure, or an on-premises data center. This ensuresconsistent security policiesacross the entire footprint. Because the enforcement is decentralized, the solution scales automatically as new cloud platforms or workloads are added. While aTraditional Firewall(Option A) lacks the multi-cloud agility, a Zone-based Firewall(Option B) is typically tied to specific physical or logical interfaces on a router, and a Host-based Firewall(Option D) is managed at the individual OS level, which becomes difficult to coordinate centrally at scale. The distributed firewall model aligns with theCisco SAFEarchitectural goal of pervasive security and simplified operations in highly dynamic, heterogeneous cloud environments.

NEW QUESTION # 24
Which two solutions help ensure consistent policy enforcement across multi-cloud workloads?
(Choose two.)

Answer: A,C

Explanation:
Cisco Secure Workload provides workload visibility and policy enforcement across environments, while cloud-delivered firewalls apply consistent security policies across multiple cloud platforms.


NEW QUESTION # 25
Which generative AI impact is addressed by a human-in-the-loop design policy?

Answer: C

Explanation:
A human-in-the-loop design policy ensures that humans validate or oversee AI-generated outputs, reducing the risk of AI hallucinations (false or misleading information generated by AI).
This provides accountability and accuracy in generative AI use.


NEW QUESTION # 26
A logistics company wants to deploy an application in the cloud using cloud native techniques.
The company must ensure that the development, testing, and production environments are as identical as possible with the lowest risk of the development and testing environments impacting production. Which solution must be used to accomplish the task?

Answer: C

Explanation:
Using separate cloud accounts for development, testing, and production ensures strong isolation between environments. This prevents accidental impact on production while maintaining consistent, cloud-native deployments across all stages with minimal risk.
