CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-003 試験問題 (Q403-Q408):

質問 # 403
During a security incident, security tools quarantine a device and create a disk image. During the analysis, the image is corrupted. Which of the following best describes how the analyst should proceed with the investigation?

正解：B

解説：
The correct answer is D. In forensic analysis, the analyst should not repair, rebuild, or modify the original device or evidence. Forensic workflows rely on validated, forensically sound images and working copies. If the analysis copy becomes corrupted, the correct approach is to return to a preserved/archived copy or original validated image and continue from a clean copy.
The Sybex CySA+ Study Guide explains that drive and media images must be captured in a forensically sound manner, validated with hashing, and copied so that the original evidence is retained. It also states that multiple copies are made so the original drive can be retained for evidence. The official CySA+ objectives also include evidence acquisition, validating data integrity, preservation, and chain of custody under incident response activities.
Why the other options are incorrect:
A is incorrect because trying to remediate corruption may further alter evidence.
B is incorrect because bootable media may alter the device or evidence state.
C is incorrect because rebuilding the OS destroys or changes forensic evidence.
D is correct because restoring from a preserved copy maintains forensic integrity.


質問 # 404
An analyst wants to detect outdated software packages on a server. Which of the following methodologies will achieve this objective?

正解：C

解説：
Credentialed scanning uses valid system credentials to access and inspect software versions installed on a server, allowing accurate detection of outdated or vulnerable packages.


質問 # 405
During a recent site survey. an analyst discovered a rogue wireless access point on the network. Which of the following actions should be taken first to protect the network while preserving evidence?

正解：B

解説：
The correct answer is D. Disconnect the access point from the network.
A rogue access point is a wireless access point that has been installed on a network without the authorization or knowledge of the network administrator. A rogue access point can pose a serious security risk, as it can allow unauthorized users to access the network, intercept network traffic, or launch attacks against the network or its devices1234.
The first action that should be taken to protect the network while preserving evidence is to disconnect the rogue access point from the network. This will prevent any further damage or compromise of the network by blocking the access point from communicating with other devices or users. Disconnecting the rogue access point will also preserve its state and configuration, which can be useful for forensic analysis and investigation.
Disconnecting the rogue access point can be done physically by unplugging it from the network port or wirelessly by disabling its radio frequency5.
The other options are not the best actions to take first, as they may not protect the network or preserve evidence effectively.
Option A is not the best action to take first, as running a packet sniffer to monitor traffic to and from the access point may not stop the rogue access point from causing harm to the network. A packet sniffer is a tool that captures and analyzes network packets, which are units of data that travel across a network. A packet sniffer can be useful for identifying and troubleshooting network problems, but it may not be able to prevent or block malicious traffic from a rogue access point. Moreover, running a packet sniffer may require additional time and resources, which could delay the response and mitigation of the incident5.
Option B is not the best action to take first, as connecting to the access point and examining its log files may not protect the network or preserve evidence. Connecting to the access point may expose the analyst's device or credentials to potential attacks or compromise by the rogue access point. Examining its log files may provide some information about the origin and activity of the rogue access point, but it may also alter or delete some evidence that could be useful for forensic analysis and investigation. Furthermore, connecting to the access point and examining its log files may not prevent or stop the rogue access point from continuing to harm the network5.
Option C is not the best action to take first, as identifying who is connected to the access point and attempting to find the attacker may not protect the network or preserve evidence. Identifying who is connected to the access point may require additional tools or techniques, such as scanning for wireless devices or analyzing network traffic, which could take time and resources away from responding and mitigating the incident.
Attempting to find the attacker may also be difficult or impossible, as the attacker may use various methods to hide their identity or location, such as encryption, spoofing, or proxy servers. Moreover, identifying who is connected to the access point and attempting to find the attacker may not prevent or stop the rogue access point from causing further damage or compromise to the network5.

質問 # 406
A security analyst is performing vulnerability scans on the network. The analyst installs a scanner appliance, configures the subnets to scan, and begins the scan of the network. Which of the following would be missing from a scan performed with this configuration?

正解：B

解説：
Registry key values would be missing from a scan performed with this configuration, as the scanner appliance would not have access to the Windows Registry of the scanned systems. The Windows Registry is a database that stores configuration settings and options for the operating system and installed applications. To scan the Registry, the scanner would need to have credentials to log in to the systems and run a local agent or script. The other items would not be missing from the scan, as they can be detected by the scanner appliance without credentials.
Operating system version can be identified by analyzing service banners or fingerprinting techniques. Open ports can be discovered by performing a port scan or sending probes to common ports. IP address can be obtained by resolving the hostname or using network discovery tools.


質問 # 407
An analyst uses an AI platform to help correlate events. The AI output contains events that did not happen. This results in inaccurate correlations. Which of the following best describes what has occurred?

正解：C

解説：
Hallucinations occur when an AI system generates outputs that are not based on real events or data, leading to fabricated or inaccurate correlations.
