VMware Certified Professional - Data Center Virtualization (VCP-DCV) Practice Exam

The command to power on a virtual machine while connected to an ESXi host using SSH utilizes the `vim-cmd` utility along with the virtual machine's ID. In the correct answer, the command structure `vim-cmd vmsvc/power.on` is followed by `12345`, which represents the specific ID of the virtual machine that you wish to power on.

Using the virtual machine ID is essential because it uniquely identifies the VM on the host. The `vim-cmd` command is a command-line interface provided by VMware for managing virtual machines from an ESXi shell or via SSH. This tool includes various subcommands, including `vmsvc/power.on`, which explicitly instructs the system to send a power-on signal to the specified virtual machine.

The format of the command is thus critical: the command must correctly reference the virtual machine's numeric ID and the `vmsvc/power.on` subcommand. Therefore, the combination of `vim-cmd`, the appropriate subcommand, and the VM's ID results in the correct command to power on the VM.

In contrast, other options may include invalid syntax or refer to non-existent commands or formats that do not conform to how `vim-cmd` functions. For
