質問 # 220
Antivirus software indicates that a workstation is infected with ransomware that cannot be quarantined. Which of the following should be performed FIRST to prevent further damage to the host and other systems?
- A. Run a full antivirus scan.
- B. Remove the LAN card.
- C. Power off the machine.
- D. Install a different endpoint solution.
正解：C
解説：
Explanation
Ransomware is a type of malware that encrypts the files on a system and demands a ransom for their decryption1. Ransomware can also spread to other systems on the network or exfiltrate sensitive data to the attackers2. Therefore, it is important to isolate the infected machine as soon as possible to contain the infection and prevent further damage3. Powering off the machine is a quick and effective way of disconnecting it from the network and stopping any malicious processes running on it12. The other options are not directly related to preventing ransomware damage or may not be effective. Running a full antivirus scan may not be able to detect or remove the ransomware, especially if it is a new or unknown variant1. Removing the LAN card may disconnect the machine from the network, but it may not stop any malicious processes running on it or any data encryption or exfiltration that has already occurred2. Installing a different endpoint solution may not be possible or helpful if the system is already infected and locked by ransomware

正解：A
解説：
Net use is a command-line tool that can be used to map a drive in Windows. Mapping a drive means assigning a drive letter to a network location or a local folder, which allows the user to access it more easily and quickly.
Net use can also be used to disconnect a mapped drive, display information about mapped drives, or connect to shared resources on another computer. Gpupdate, hostname, and dir are not command-line tools that can be used to map a drive.
質問 # 223
A BSOD appears on a user's workstation monitor. The user immediately presses the power button to shut down the PC, hoping to repair the issue. The user then restarts the PC, and the BSOD reappears, so the user contacts the help desk. Which of the following should the technician use to determine the cause?
- A. System Configuration
- B. Stop code
- C. Event Mewer
- D. Services
正解：B
解説：
When a Blue Screen of Death (BSOD) appears on a Windows workstation, it indicates that there is a serious problem with the operating system. The stop code displayed on the BSOD can provide valuable information to help determine the cause of the issue. The stop code is a specific error code that is associated with the BSOD, and it can help identify the root cause of the problem.
In this scenario, the user has encountered a BSOD and has restarted the PC, only to see the BSOD reappear. This suggests that the problem is persistent and requires further investigation. By analyzing the stop code displayed on the BSOD, a technician can begin to identify the underlying issue and take appropriate actions to resolve it.

The courts determined that a cybercrimes case could no longer be prosecuted due to the agency's handling of evidence. Which of the following was MOST likely violated during the investigation?
- A. Open-source software
- B. Chain of custody
- C. EULA
- D. AUP
正解：B
解説：
Chain of custody is a process that documents how evidence is collected, handled, stored and transferred during a cybercrime investigation. It ensures that the evidence is authentic, reliable and admissible in court. If the chain of custody is violated during an investigation, it can compromise the integrity of the evidence and lead to the case being dismissed. Open-source software, EULA (end-user license agreement) and AUP (acceptable use policy) are not related to cybercrime investigations or evidence handling.

質問 # 228
Which of the following threats will the use of a privacy screen on a computer help prevent?
- A. Shoulder surfing
- B. Impersonation
- C. Whaling
- D. Tailgating
正解：A
解説：
Explanation
Shoulder surfing is a threat that involves someone looking over another person's shoulder to observe their screen, keyboard, or other sensitive information. Shoulder surfing can be used to steal passwords, personal identification numbers (PINs), credit card numbers, or other confidential data. The use of a privacy screen on a computer can help prevent shoulder surfing by limiting the viewing angle of the screen and making it harder for someone to see the screen from the side or behind. Impersonation, whaling, and tailgating are not threats that can be prevented by using a privacy screen on a computer.
