CompTIA 220-1102 Exam Dumps - Valid Questions Answers

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. 

Phishing is the correct answer for this question. Phishing is a type of attack that uses fraudulent emails or other messages to trick users into revealing sensitive information or installing malicious software. Phishing emails often impersonate legitimate entities or individuals and offer incentives or threats to lure users into clicking on malicious links or attachments. In this scenario, the user received a removable USB device in the mail as a prize, which could be a phishing attempt to infect the user’s computer with malware or gain access to the user’s data. Dumpster diving, tailgating, and evil twin are not correct answers for this question. Dumpster diving is a type of attack that involves searching through trash bins or recycling containers to find discarded documents or devices that contain valuable information. Tailgating is a type of attack that involves following an authorized person into a restricted area without proper identification or authorization. Evil twin is a type of attack that involves setting up a rogue wireless access point that mimics a legitimate one to intercept or manipulate network traffic. References:

The most likely causes of the user’s Windows computer performance degradation and freezing are insufficient RAM and excessive software running in the background. Therefore, the technician should do the following to resolve the issue:

• Increase the RAM. RAM is the memory that the computer uses to store and run applications and processes. If the RAM is not enough to handle the workload, the computer will use the hard drive as a virtual memory, which is much slower and can cause performance issues. Increasing the RAM will allow the computer to run more applications and processes smoothly and avoid freezing. The technician should check the system requirements of the applications that the user needs to run, and install additional RAM modules that are compatible with the motherboard and the existing RAM. The technician should also make sure that the system is managing the page file size automatically, or adjust it manually to optimize the virtual memory usage12.
• Uninstall unnecessary software. Software that the user does not need or use can take up valuable disk space and system resources, and can interfere with the performance of other applications. Some software may also run in the background or start automatically when the computer boots up, which can slow down the system and cause freezing. The technician should help the user to identify and uninstall unnecessary software from the control panel or the settings app, and disable unnecessary startup programs from the task manager or the system configuration tool. The technician should also check for and remove viruses and malware that may affect the system performance134.
