EOL (end-of-life) is a term that indicates a vendor no longer supports a product. It means that the product will no longer be sold, updated or patched by the vendor, and that the users should migrate to a newer version or alternative product. AUP (acceptable use policy), EULA (end-user license agreement) and UAC (user account control) are not terms that indicate a vendor no longer supports a product.

netstat is a tool that can be used to investigate connections on a Windows machine. It displays information about the active TCP connections, listening ports, routing tables, network statistics, etc.

nslookup is a tool that can be used to query DNS servers and resolve domain names to IP addresses.

net use is a tool that can be used to connect or disconnect network drives or printers. net user is a tool that can be used to create or modify user accounts on a Windows machine. Verified Reference:

One of the possible ways to access the user's computer remotely is to use RDP, which stands for Remote Desktop Protocol. RDP is a protocol that allows a user to connect to another computer over a network and use its graphical interface. RDP is commonly used for remote desktop software, such as Microsoft Remote Desktop Connection1. To use RDP, the user's computer must run RDP server software, and the technician must run RDP client software. The technician can then enter the user's IP address or hostname, and provide the appropriate credentials to log in to the user's computer.

Once connected, the technician can view and control the user's desktop, and review the Outlook settings.

The best way for a technician to return the device to service safely is to reinstall the operating system. This is because the device is infected by ransomware, which is a form of malware that encrypts files and demands payment for decryption. Reinstalling the operating system will erase the ransomware and restore the device to its original state. However, this will also delete any data that was not backed up before the infection. Therefore, it is important to have regular backups of critical data and protect them from ransomware attacks1.

The other options are not effective or safe for ransomware recovery. Running an AV scan may not detect or remove the ransomware, especially if it is a new or unknown variant. Installing a software firewall may prevent future attacks, but it will not help with the current infection. Performing a system restore may not work if the ransomware has corrupted or deleted the restore points.

Complying with the on-screen instructions is not advisable, as it will encourage the attackers and there is no guarantee that they will provide the decryption key after receiving the payment.

To prevent and recover from ransomware attacks, it is recommended to follow some best practices, such as234:

Use strong passwords and multifactor authentication for all accounts and devices.

Keep all software and firmware updated with the latest security patches.

Avoid opening suspicious or unsolicited emails and attachments.

Educate users and staff on how to recognize and report phishing and social engineering attempts.

Use antivirus software and enable real-time protection.

Enable network segmentation and firewall rules to limit the spread of ransomware.

Implement a Zero Trust security model to verify all requests and devices before granting access.

Create and test backups of critical data and store them offline or in a separate network.

Recover safely by isolating the infected devices, identifying the ransomware variant, and restoring data from backups.

Report any ransomware incidents to law enforcement agencies and seek help from experts.

The correct answer is B. Printer Properties/Sharing tab. This is the location where the technician can enable printer sharing and assign a share name for the USB printer. This will allow other computers on the network to access the printer by using the share name or the IP address of the computer that has the printer attached1.

The correct answers are D. Restricting log-in times and E. Enabling a screen lock. These are the security measures that can be used to prevent the computers from being accessed by unsupervised contractors in the building.

Restricting log-in times means setting a policy that allows users to log in only during certain hours, such as the regular working hours of the company. This will prevent unauthorized access by contractors who work at night1.

Enabling a screen lock means setting a policy that requires users to enter a password or a PIN to unlock their screens after a period of inactivity. This will prevent unauthorized access by contractors who might try to use the computers when the users are away2.

The correct answer is

A. Verify the DNS server settings. This is because the DNS server is responsible for resolving domain names to IP addresses, which is necessary for accessing the internet or named network resources. If the DNS server settings are incorrect or the DNS server is down, the technician will not be able to access these resources even if they have a valid IP address and can ping the default gateway1.

The correct answers are B. Removing the applications from startup and E. Defragmenting the hard drive. These are the operations that would be best to do to resolve the issue of a slow boot at a minimal expense.

Removing the applications from startup means disabling the programs that run automatically when the PC is turned on. This will reduce the load on the CPU and RAM and speed up the boot process1.

Defragmenting the hard drive means rearranging the files on the disk so that they are stored in contiguous blocks. This will improve the disk performance and reduce the time it takes to read and write data2.

Calibrating the phone sensors is a step that can troubleshoot the issue of screen not autorotating on a mobile device. Screen autorotation is a feature that automatically adjusts the screen orientation based on the device's position and movement. Screen autorotation relies on sensors such as accelerometer and gyroscope to detect the device's tilt and rotation. Calibrating the phone sensors can help fix any errors or inaccuracies in the sensor readings that may prevent screen autorotation from working properly. Enabling the touch screen, reinstalling the operating system, and replacing the screen are not steps that should be done next to troubleshoot this issue.
