Most Recent CompTIA 220-1102 Exam Questions & Answers

When handling a user support request that contains insufficient information, the first step a technician should take is to Ask the user for clarification (A). This involves gathering more details about the issue to understand the problem better and provide an accurate resolution. Effective communication and asking the right questions are essential for diagnosing and resolving IT issues efficiently.

Detailed Explanation with Core 2 Reference:

If multiple unsuccessful attempts led to the account being locked, the technician should unlock the account. Core 2 covers user account management practices, including unlocking accounts and managing failed login attempts (Core 2 Objective 2.5).

SQL injection is a type of attack that takes advantage of vulnerabilities in a web application's database query software, allowing an attacker to send malicious SQL commands through the application to the database. These commands can manipulate the database and can lead to unauthorized data access or manipulation.

SQL injection: In the scenario described, the malicious user was able to export an entire website's user database by entering specific commands into a field on the company's website, which is a classic example of an SQL injection attack. This type of attack exploits vulnerabilities in the database layer of an application to execute unauthorized SQL commands.

Cross-site scripting (A) involves injecting malicious scripts into content from otherwise trusted websites. A brute-force attack (C) is an attempt to gain access to a system by systematically checking all possible keys or passwords until the correct one is found. A DDoS attack (D) is an attempt to make a machine or network resource unavailable to its intended users by overwhelming it with a flood of internet traffic.

The technician should use devmgmt.msc tool to make adjustments for the touchpad issue after Windows installed updates on a laptop. Devmgmt.msc is a command that opens the Device Manager, which is a utility that allows users to view and manage the hardware devices and drivers installed on a computer. The technician can use the Device Manager to check the status, properties and compatibility of the touchpad device and its driver, and perform actions such as updating, uninstalling or reinstalling the driver, enabling or disabling the device, or scanning for hardware changes. Eventvwr.msc is a command that opens the Event Viewer, which is a utility that allows users to view and monitor the system logs and events. The Event Viewer may provide some information or clues about the touchpad issue, but it does not allow users to manage or troubleshoot the device or its driver directly. Perfmon.msc is a command that opens the Performance Monitor, which is a utility that allows users to measure and analyze the performance of the system

When an organization refuses to pay the ransom for a decryption key after a ransomware attack, and all traces of the infection have been removed, the next critical step is:

Restore critical data from backup: This is the most effective way to recover from a ransomware attack without paying the ransom. Assuming the organization has good backup practices, the backups should be free from infection and can be restored to get the systems operational again.

Scan all of the infected files with up-to-date, anti-malware cleaning software: This step is important during the infection removal process but does not address restoring the encrypted files.

Fully patch the server operating systems hosting the fileshares: While this is necessary to prevent future attacks, it does not recover the encrypted files.

Change the files to be read-only: This will not help recover the encrypted data.
