問題 #90
The Digital Forensics and Incident Response (DFIR) team notices many encrypted files on an endpoint. The team also determines that the threat uses stolen Remote Desktop Protocol (RDP) credentials. The DFIR team responds according to the internal incident-response playbook. Which two elements make up the containment phase for this incident? (Choose two.)
答案：D,E
解題說明：
Endpoint segmentation contains the ransomware by isolating affected systems and restricting east-west movement, thereby limiting additional encryption and preventing the attacker from reaching other assets through RDP. Multifactor authentication addresses the second active risk: stolen credentials. Requiring another factor makes the captured password insufficient for renewed remote access and helps contain credential-based lateral movement. System information discovery is an attacker behavior, not a defensive control. A steganographic decoder is an analysis utility unrelated to ransomware containment, while a traffic- scrubbing service is primarily used against volumetric denial-of-service traffic. In a playbook, these actions should be accompanied by credential revocation, session termination, evidence preservation, and scoping, but those choices are not offered. This maps to CBRFIR Incident Response Processes objective 5.2, which requires evaluating playbook elements, and to the course's framework for responding to incidents. Cisco CBRFIR training overview
問題 #91
Refer to the exhibit.
A company that uses only the Unix platform implemented an intrusion detection system. After the initial configuration, the number of alerts is overwhelming, and an engineer needs to analyze and classify the alerts.
The highest number of alerts were generated from the signature shown in the exhibit. Which classification should the engineer assign to this event?
答案：D
解題說明：
The alert shown is based on a Snort rule for a Unicode directory traversal attack against IIS web servers (Microsoft platform). The key detail here is the payload content " ../..%c0%af../ " which is a classic IIS- specific exploit related to CVE-2000-0884.
Since the company only uses Unix systems, they are not vulnerable to this IIS-specific attack. Therefore, these alerts are triggered by irrelevant traffic or misapplied signatures, resulting in False Positives.
As defined in the Cisco CyberOps guide:
"False Positive: an alert is generated for traffic that is not actually malicious or relevant to the protected environment".
問題 #92
Which two tools conduct network traffic analysis in the absence of a graphical user interface? (Choose two.)
答案：B,C
解題說明：
* TCPdumpis a CLI-based packet capture tool that is widely used for real-time traffic inspection and analysis on Unix/Linux systems.
* TCPsharkis a variant CLI tool used similarly for packet analysis.
AlthoughWiresharkis a powerful network protocol analyzer, it requires a GUI. Therefore, it is not suitable for environments without a graphical interface.
問題 #93
Refer to the exhibit.
An experienced cybersecurity analyst is investigating a sophisticated suspected breach on a Windows server within an enterprise network and compiled the evidence gathered so far Which action should the analyst prioritize to understand the scope and impact of the breach?
答案：A
問題 #94
An "unknown error code" is appearing on an ESXi host during authentication. An engineer checks the authentication logs but is unable to identify the issue. Analysis of the vCenter agent logs shows no connectivity errors. What is the next log file the engineer should check to continue troubleshooting this error?
答案：C
