220-1102 Exam Questions Tutorials

Windows is widely used in industrial and business environments due to its major market presence, extensive support from the industry, and a broad selection of operating system options. It supports a wide variety of software, making it suitable for running complex systems like an inventory management system in a factory. Other options such as Chrome OS, Android, and iOS are either more consumer-oriented or designed for specific types of devices, making them less likely choices for an industrial application like inventory management.References: Professor Messer’s CompTIA 220-1102 A+ Course Notes​​.

MFA stands for multi-factor authentication, which is an electronic authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN1. MFA provides security enhancement by making it harder for attackers to compromise the user’s identity or credentials, as they would need to obtain more than just the username and password. MFA can also prevent unauthorized access to sensitive data or resources, as well as reduce the risk of identity theft or fraud2. 

The first mitigation step that a technician should take when a machine is suspected to contain ransomware is to quarantine the system. This means isolating the infected machine from the network and other devices, to prevent the ransomware from spreading and encrypting more data. The technician can quarantine the system by disconnecting the network cable, turning off the wireless adapter, or using firewall rules to block the traffic from and to the machine12.

This step is more important than the other options because:

Disabling System Restore (A) is not a priority, as it will not stop the ransomware from running or spreading. System Restore is a feature that allows users to restore their system to a previous state, but it may not work if the ransomware has encrypted or deleted the restore points. Moreover, disabling System Restore may prevent the user from recovering some data or settings in the future13.

Remediating the system (B) is the ultimate goal, but it cannot be done before quarantining the system. Remediating the system means removing the ransomware, restoring the data, and fixing the vulnerabilities that allowed the attack. However, this process requires careful analysis, planning, and execution, and it may not be possible if the ransomware is still active and communicating with the attackers. Therefore, the technician should first isolate the system and then proceed with the remediation steps12.

Educating the system user © is a preventive measure, but it is not a mitigation step. Educating the system user means raising awareness and providing training on how to avoid ransomware attacks, such as by recognizing phishing emails, avoiding suspicious links or attachments, and updating and patching the system regularly. However, this step will not help if the system is already infected, and it may not be effective if the user is not willing or able to follow the best practices. Therefore, the technician should focus on resolving the current incident and then educate the user as part of the recovery plan14.

Copying the program file to a USB drive and installing it from there is the simplest and most reliable way to transfer the software from the network share to the Windows tablet. The other options are either unnecessary, risky, or impractical. Burning the program file to a CD requires a CD burner and a CD reader, which may not be available on the tablet. Formatting or replacing the HDD will erase all the data and settings on the tablet, which is not advisable unless there is a backup or a serious problem. Moreover, formatting or replacing the HDD will not solve the issue of copying the program file from the network share.
