Cisco Designing Cisco Security Infrastructure 300-745 Prüfungsfragen mit Lösungen (Q26-Q31):

26. Frage
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?

Antwort: C

Begründung:
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.


27. Frage
Which tool is used by a SOC analyst to quarantine an endpoint?

Antwort: A

Begründung:
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.

28. Frage
A manufacturing company experienced a security breach that resulted in sales data being compromised. An engineer participating in the investigation must identify who logged into the sales system during the affected period. Which approach must be used to gather the information?

Antwort: A

Begründung:
AAA (Authentication, Authorization, and Accounting) provides accounting logs that record who logged in, when, and from where. During an investigation, these logs allow the security team to trace user logins to the sales system and identify who accessed it during the breach period.


29. Frage
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?

Antwort: D

Begründung:
Enabling AAA authentication on the default connection profiles ensures that all VPN access attempts must go through strong authentication. This directly mitigates password spray attacks by enforcing centralized authentication controls, enabling account lockout, and supporting additional protections such as multifactor authentication.


30. Frage
Which two solutions help ensure consistent policy enforcement across multi-cloud workloads?
(Choose two.)

Antwort: C,D

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