質問 # 14
An oil and gas company recently faced a security breach when an employee's notepad, which contained critical login credentials, was stolen. The incident led to unauthorized access to a user account, which posed a significant risk to sensitive company data and operations. The company wants to adopt a security measure that enhances user account protection. Which action must be taken to prevent breaches like this from happening in the future?
正解：A
解説：
Multi-Factor Authentication (MFA) strengthens user account security by requiring additional verification factors beyond passwords, such as tokens or biometrics. Even if credentials are stolen, MFA prevents unauthorized access, directly addressing the breach scenario.
質問 # 15
Which tool is used by SOC analyst to quarantine an endpoint?
正解：B
解説：
Cisco XDR (Extended Detection and Response) gives SOC analysts the ability to detect, investigate, and quarantine compromised endpoints. It integrates telemetry across endpoints, network, and cloud, enabling coordinated response actions.
質問 # 16
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?
正解：B
解説：
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.
質問 # 17
Which benefit does AI provide in network security?
正解：C
解説：
According to the Cisco SDSI v1.0 objectives, Artificial Intelligence and Machine Learning (ML) provide significant benefits in automating the identification of complex security weaknesses. One of the primary benefits is the ability of AI to performEncrypted Threat Analytics (ETA). AI models can analyze the metadata and initial handshake patterns of encrypted traffic-without needing to decrypt it-toidentify vulnerabilities associated with weak TLS algorithmsor outdated cipher suites.
By recognizing specific fingerprints in the TLS handshake, AI-driven tools can alert administrators to non- compliant encryption standards that might be susceptible to interception. While AI is a powerful force multiplier, it doesnot replacea comprehensive defense-in-depth strategy (Option B); rather, it enhances it. It does not directlyspeed up data transmission(Option A), as that is a function of hardware and bandwidth.
Furthermore, while AI helps mitigate DDoS attacks, it rarely provides "complete" protection (Option C) on its own, as DDoS mitigation requires a multi-layered approach involving massive bandwidth and specialized scrubbing. The ability to identify cryptographic weaknesses at scale is a core functional benefit of AI in modern security infrastructure, aligning with the Cisco goal of maintaining a hardened and compliant network posture through automated visibility.
質問 # 18
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?
正解：D
解説：
In the aftermath of a security breach, forensic investigators rely on theAccountingportion ofAAA (Authentication, Authorization, and Accounting)to reconstruct a timeline of events. While Authentication verifies identity and Authorization defines permissions, Accounting is the specific framework used to track user activity, including login/logout times and the specific commands executed during a session.
According to Cisco Security Infrastructure design objectives, implementing a centralized AAA solution (such asCisco Identity Services Engine (ISE)or a TACACS+/RADIUS server) is critical for accountability. In this scenario, the engineer would query the AAA logs to identify exactly "who" accessed the sales system during the compromise period.SNMP(Option A) is primarily for network monitoring and performance data, not granular user access logs.NACM(Option B) is an access control model for NETCONF but doesn't provide the broad auditing required here.PKI(Option D) provides the certificates used for digital signatures and encryption but does not log the historical "session" data needed for the investigation. Therefore, AAA is the fundamental architectural requirement for ensuring non-repudiation and providing the audit trail necessary to satisfy risk management and incident response requirements.
