Final answer:
The correct path for mapping a network drive in Windows is option B, which is \\servername\usershare. It uses backslashes as required by Windows networking standards.
Step-by-step explanation:
When mapping a network drive, a technician would use the following path format: \\servername\usershare.
This is because in Microsoft Windows based systems, network paths are typically indicated by two backslashes followed by the server name and then the share name, separated by another single backslash.
Thus the correct answer to the provided question is option B: \\servername\usershare.
It's important to use backslashes instead of forward slashes and there should be no spaces between servername and usershare.
This path tells the operating system where to find the network resource.
