faulty components on the office printer to
resolve the stated issues.
If at any time you would like to bring back
the initial state of the simulation, please click
the Reset All button.

Given that the laptop is shutting down intermittently and making noise when repositioned, the issue might be related to loose or damaged internal components. The technician should first look for any loose or potentially obstructive parts that could be causing the issue.

A sandbox environment is designed to isolate and contain software or programs, preventing them from interacting with other parts of the system or network. This isolation can be used to safely run untested or untrusted programs or code without risking the integrity of the host system or network. Setting up a virtual machine within a sandbox environment ensures that the VM has no communication with other devices over the network, providing a controlled and secure environment for testing or development purposes.

Explanation
The default gateway is the IP address of the router or device that connects a network to another network or the internet. In the output below, the default gateway is 172.25.1.252, as shown in the line "Default Gateway . . . .
. . . . . : 172.25.1.252". The other IP addresses are not default gateways, but either local IP addresses (172.25.1.39 and 172.25.1.4) or subnet masks (255.255.255.0).

The quickest way to resolve the issue is to install a Power over Ethernet (PoE) injector to provide power to the IP phone. An unmanaged switch does not provide PoE, so an injector is needed to power the phone.
