Which file from the virtual machine directory is required to provide the suspended virtual machine's memory contents to technical support?

The file required to provide the suspended virtual machine's memory contents to technical support is the .vmss file. This file contains the memory state of the virtual machine at the moment it was suspended. When a virtual machine is suspended, its memory is saved to this file, allowing the machine to resume from that exact point later on.

This capability is important for technical support because having access to the .vmss file allows them to analyze the state of the virtual machine at the time of suspension, which can be crucial for troubleshooting any issues that might have led to the suspension or for understanding the virtual machine’s operations during that time.

The other files, while important to the virtual machine's functionality, serve different purposes. The .vmdk file is used for the virtual disk(s) of the VM, the .log file contains logs of the VM's operations, and the .vmx file is the configuration file that holds settings for the virtual machine. Each of these files contributes to the VM’s operation but does not hold the suspended state memory information necessary for technical support analysis.
