CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-004 試験問題 (Q65-Q70):

質問 # 65
A cybersecurity analyst receives an unstructured text document that contains advanced persistent threat (APT)-related indicators of compromise (IoCs). The analyst needs to extract the IPv4 addresses. Which of the following is the best tool to accomplish this task?

A. CyberChef
B. Zeek
C. Open Cyber Threat Intelligence (OpenCTI)
D. Wireshark

正解：A

解説：
CyberChef can parse unstructured text and extract IPv4 addresses using built-in extraction and regular-expression operations. Wireshark and Zeek analyze network traffic, while OpenCTI manages threat intelligence.

質問 # 66
Users frequently get disconnected from the company's internal wireless network. The wireless system and clients are healthy. Once disconnected, the wireless clients reconnect automatically.
Which of the following is the best way for a security analyst to determine the source of the wireless disconnection?

A. Utilizing aireplay-ng to disconnect the malicious wireless station and capture its handshake
B. Using a client with kismet to analyze the airspace for potential deauthentication attacks
C. Looking at authentication logs for impossible travel
D. Collecting the RADIUS logs and investigating the IP addresses of failed user authentications

正解：B

解説：
Deauthentication attacks force wireless clients to disconnect from an access point by sending forged deauthentication frames. Since the clients automatically reconnect and the wireless infrastructure appears healthy, analyzing the wireless airspace with Kismet is the best way to detect unauthorized deauthentication frames and determine whether a wireless attack is causing the disconnects.

質問 # 67
An analyst is assigned to a new cybersecurity improvement project. The analyst wants to better understand the workflow processes and the skill set of the cybersecurity engineers on this task force. The analyst sets up a recurring, weekly conference call. Which of the following best describes the purpose for the conference call?

A. To create vendor information sessions
B. To conduct incident response training
C. To manage and facilitate team coordination
D. To respond to customer requirements

正解：C

解説：
A recurring team call supports information sharing, workflow alignment, role awareness, and coordination among the cybersecurity engineers.

質問 # 68
A vulnerability scanner shows discrepancies between the number of Internet Protocol (IP) addresses across the sites being scanned and the number of systems reporting into the patching system. Which of the following actions will resolve this issue?

A. Enable verbose logging in the scanner and check for failures.
B. Conduct a comprehensive asset inventory with the infrastructure team.
C. Request the infrastructure team rerun patching deployments.
D. Rebuild the vulnerability report selection criteria to account for all sites.

正解：B

解説：
An asset inventory reconciles discovered IP addresses with known systems and identifies unmanaged, duplicated, or missing assets that are not reporting to the patching platform.

質問 # 69
Which of the following occurs during the analysis phase of the incident response process?

A. Alert writing
B. Isolation
C. Reimaging
D. Triage

正解：D

解説：
During analysis, alerts are validated and triaged to determine the incident's severity, scope, priority, and potential impact. Reimaging is recovery, while isolation is containment.
