A+ 220-1101 Release Date

To connect printers without an RJ45 port to the network, the technician needs to enable wireless connectivity. By configuring the printers to connect to the network wirelessly, the company can achieve the desired consistency in printer configuration across the office. This approach allows printers without built-in wired network capabilities to be part of the network, facilitating shared access and remote printing functionalities.

When a printer is offline for one user but works for others, the issue often lies in the user's print queue settings, such as a paused queue or failed print jobs. Checking and clearing the print queue can resolve the problem.

Why Not B (Check the printer's IP address): If other users can print, the printer’s IP address is not the issue.

Why Not C (Check the user's network settings): Network issues are unlikely if the user can access other resources on the network.

Why Not D (Check the printer's firmware version): Firmware issues would affect all users, not just one.

Given the network information for the server “InternalToolCentral” with an IP address of “192.130.230.5” and a subnet mask of “255.255.255.0”, the gateway address should be within the same network range. However, the gateway address is listed as “192.130.230.1”, which is correct and within the same subnet. Therefore, the issue is not with the gateway settings.

The DNS servers are listed as “8.8.8.8” and “4.2.2.1”, which are public DNS servers and should be able to resolve domain names correctly if they are reachable.

The open ports listed include 25 (SMTP), 80 (HTTP), 110 (POP3), 443 (HTTPS), and 3306 (MySQL), which are standard ports for their respective services.

Considering the provided options and the network settings, the most likely explanation for users being unable to access resources on the file server is: A. Applicable ports have been closed during routine hardening. This could prevent users from connecting to the necessary services on the file server.

The issue described suggests the 12V CPU power connector was likely forgotten during installation. The 12V power rail is essential for the operation of high-end workstation components, including the CPU. Without the 12V connection, the system will fail to POST and may power off shortly after being turned on.

Why 12V?

The 12V connector is critical for providing power to the CPU via the motherboard. Modern CPUs require a dedicated power source from the PSU, usually supplied through the 4-pin or 8-pin EPS12V connector.

If this connection is omitted, the motherboard will not receive adequate power for the CPU to function, resulting in the system failing to POST or shutting down after a brief period.

Incorrect Options:

A. 5V: The 5V rail powers USB devices, some motherboard components, and certain peripherals, but not the CPU directly.

C. 120V and D. 220V: These voltages refer to the power supply’s input from the wall outlet, not the internal connections to components.
